Master volume controls reduce the signal going from the preamp section to the power amp section, allowing you to run the preamp tubes into distortion at lower volumes. An attenuator reduces the output power level going from the power amp section to the speaker, allowing you to run both the preamp and power amp into distortion at lower volumes Dr. Z AMA: Master Volume vs. Attenuators - YouTube.

Joined: Apr 30, 2008 Location: Portugal. So, it seems that many people seem to dislike master volume fenders (late 70's). But others like to use attenuators to tame their non master volume beasts. Isn't it the same thing?. Master volumes are not attenuators. Master volume is usually somewhere between preamp and poweramp and controls the output level there. If you have a multichannel amp you might have channel volumes which you can regard as preamp volume levels, mostly meant for balancing channels so your overdrive channel does not output at a much higher level than your clean for example Der Amp ist also voll aufgedreht, die Endstufenröhren müssen hart arbeiten und erzeugen einen satten Sound, während sich aus den Lautsprechern ein reduzierter Schalldruck den Weg ins Ohr bahnt. Sozusagen ein zusätzlicher Master-Volumenregler für die Box. Dieses Prinzip wird auch als Power Attenuator bezeichnet
That is not to say it won't sound good with a master---just different. A combination of a master volume and an attenuator is often needed for such amp. A better solution for many players who want real power tube breakup is to use a lower wattage amp or an amp with London Power Scaling like some of the model we build at Carl's Custom Amps. Post Phase Inverter vs. Pre-Phase Inverter Master. Power scaling can be applied throughout the amp, so all the valves produce less power. Alternatively, it can just be applied to the power tubes, but a master volume control may be required to prevent the preamp from driving the power stage too hard. Many amp builders are now using power scaling, and a big advantage over using external attenuators is that the life of the valves might be extended rather than reduced
What I found with that particular amp was that while there was a difference in sound between the master volume and the attenuator, it wasn't really a big enough difference to make it worth the effort. Oh, and a Mark V with the master volume hard bypassed and the channel volumes all set to noon is loud enough to sterilize a water buffalo from 300 yards.

I almost always use an attenuator for my master volume / modern amps. It sounds better than just running the master low, and by better I mean closer to running it loud.

It's a ClassAB power amp, the tubes are biased. One of the lesser understood elements of getting great guitar tone is volume. Live Wire. Sure, everybody knows that tube amps sound good when they're played loud. That's not where I'm going with this. Let's look at the opposite direction. Often amps that don't reach a certain volume sound choked. A 100-watt amp on 2 isn't going to sound like that same amp on 4. This doesn't have.

I prefered the sound of the amps master volume at low levels better than the sound using the hot plate. Now, I just picked up the Ultimate Attenuator and thus far my opinion of it concurs with others I've read - it is much better at attenuating down to bedroom levels however the Hotplate is probably a bit better in the moderate attenuation zone of -4 to -12 dB.

Amp attenuators are devices that solve a very old problem that is specific to tube amps. If you want good distortion, you have to crank the volume to the max. This has to do with the fact that power tubes provide the best sound once they are under maximum load. So in general, the rule of thumb is that the quality of sound increases with the volume Re: Post Phase Inverter Master Volume vs Attenuator Post by SeveBC » Tue Nov 16, 2010 2:43 am Weber recommends up to twice the maximum rated power output of your amp attenuator vs Master Volume on a modded Fender Twin.

When an amp has two volume knobs like this, the first VOLUME is most often used to dial in preamp stage distortion while the MASTER is used to control overall volume. Master Volumes however, change the tone of an amplifier and often don't allow the power section to overdrive which is where a lot of secret buttery tones live in an amp Bei einem Röhrenverstärker hat der Volumenregler durchaus auch einen Effekt auf die Klangfarbe. Nämlich genau dann, wenn das Volumen so weit aufgedreht wird, dass die dahintersteckenden Röhren eine immer stärkere klangliche Sättigung erzeugen. Es kommt also zu einer Endstufenverzerrung, die einen ganz eigenen Klangcharakter mitbringt. In der 12. Folge von delamar Guitar erfährst Du mehr When he did the modding he unhooked it from the master volume, which now does nothing, and the amp now is only controlled by the volume knobs on each of the channels. I would like to get a more saturated tone at a reasonable volume, so I was thinking about getting an attenuator or having the master volume rehooked up. The thing about an attenuator is that there is nowhere to plug one in in the back of the amp (i believe) between the speakers and the amp. Anyone know if this can be created by. Attenuators. I think the concept here is simple. You turn your amp up as loud as you want it, and then reel it back down to a listenable volume. The idea is to get the power tubes working. It works like a post amp master volume and goes between your amp and cabinet. I've never actually tried one out, so I really don't know how effective or necessary these things are
There is no real reason to use an attenuator with an amp with proper master volume. You loose a lot more than you gain. Marshall Plexi 100w? Hell yes, you need one. You are better off with something like a Fryette Power Station 100 or a Boss Waza Tube Amp Expander. Most probably you have never heard your amp with the power section cooking and there is a high chance you will not like it. High gain amps and distorting power sections don't gel usually Whats the dif between tube amp volume box and an attenuator or a power soaker. Ive been looking into getting one of these now that were playing smaller venues and was wondering if anyone else has tried them and what they thought of them. Thanks Get a passive attenuator. Since it doesn't amplify the signal, its gain ranges from 0 to 1, which gives you a much larger usable range. Have two analogue volume controls. If your power amplifier or speakers have a volume or input trim control, that will work great. Use that to set a master volume level so that your regular volume control's usable range is maximised. If the previous two. The Weber MicroMass Attenuator is a reliable 15-watt attenuator used with 4-ohm, 8-ohm, and 16-ohm amplifiers. It has a low-mid knob and a mid-high knob. The former is used for controlling the master volume, while the latter adjusts the treble to warm up or brighten the tone. This unit offers complete control to an attenuation of -50 decibels. A speaker motor is used for the load, allowing the attenuator to interact more with the amplifier's output circuit and resulting in a more realistic.
Master Volume controls the overall volume of all the presets as a whole. This setting is handled physically via the knob on the amplifier itself and is not a part of any Channel/Preset, it acts as the knobs do when the amp is in Panel mode. 4. Share.

This has been the consensus of audiophiles for many years. But unlike common potentiometers (or other stepped attenuator brands), our stepped attenuators provide very clear sound and precise signal level matching. All Goldpoint stepped attenuators have make-before-break switch contacts, so as not to create clicks or pops while changing levels. Our switch contacts have unusually thick hard-gold plating - and are low contact bounce. They serve as impressive potentiometer upgrades, are easy. . Now after messing around with it I'v managed to get a..
PPIMV (Post-Phase-Inverter-Master-Volume) is by far the most transparent MV that can be added to an amplifier, due to it's location in the circuit being after the preamp gain stages and phase inverter. When it is turned to max, it is essentially taken out of the circuit (ala Matchless type MV). The layout listed is for implementing this Mod in a JTM50 circuit, but will easily translate to any of the circuits listed above without issue. Mod Kit includes Dual 250KA pot, (2) 2.2M resistors, 2FT. I mic my class 5 so for fun I tried heavily attenuated (orpheus class5 attenuator) VS full volume. The difference is sustain and room resonation, which are wicked but you can live without them. I agree with above about just using the master volume though. Unless you're going for power tube saturation it doesn't matter, except that tube amps generally have a threshold somewhere around 1-3 on. I have found that the stepped attenuator (volume control) value is usually not so critical - and that it does not make as much difference as some people claim - but that other aspects of the equipment or system can make bigger, more noticeable sonic differences. There is a common misconception that higher value volume controls such as 50K or 100K will result in LOUDER sound compared to using.
Source selection is via the small switch by the volume control knob. Photograph 3: Rear - DIY Stepped Attenuator Volume Control. The insides of the unit are almost as tidy as the outside. Here is a shot of the interior of the unit prior to base installation. Photograph 4: Inside - DIY Stepped Attenuator Volume Control. Wiring is a little tight. Given a chance to do it again, I would probably make the box just a little bigger front to back to leave more room between the selector. Ok, this is probably a stupid question, but I have to ask. When using a tube amp, to hit that sweet spot where you get the amps overdrive working, you have to turn the volue on the amp up. Generally somewhere past 6 or 7. So a lot of folks use a power attenuator to cut the volume (yes I am aware. Be aware that this is a volume attenuator that lowers pre-amp volume INTO the power stage, as such it sits in the effects loop. It'll attenuate from zero (no signal to power amp) to wide open (like it's not there). I have it on my pedalboard in the loop of a Mesa Boogie 5/25. The Boogie is LOUD, that's fine in a band setting but unacceptable at home, with this little baby in my loop I can dial her back to entirely 'bedroom' levels without killing tone. I say that but in truth maybe the last.
In the Master section, there's the distinctive VOX Tone Cut and Master Volume that allow you to obtain a variety of sounds ranging from the extraordinarily sparkling VOX clean tone to a powerful, raw overdrive. The familiar VOX Tremolo and Spring Reverb from the Custom Series are also found in the new AC30CH and AC15CH. These effects can be switched on/off using the optional VOX VFS2A foot. Although behaving just like a ladder attenuator for each switch position, shunt attenuators vary the impedance as seen by the signal source. To minimize this, one wants to choose a large value input-to-output resistor. This can conflict with the need to have a small input-to-output resistor so that the attenuator will pass the maximum signal level at high volume settings (and have less effect. On every pioneer mixer there is an Master ATT knob in the back of the mixer, then you can choose the MAX volume the mixer can generate. In my DJM 900 I get really low volume in some clubs, and I just noticed there isn't any knob in the back of the mixer (in other pioneer mixers there it) who can gain more volume
The Master Volume is a pre-phase inverter master volume versus the more common post phase inverter master volume (PPIMV). The pre master volume controls the signal level flowing into the phase inverter and controls the distortion level of both the phase inverter and the power tubes. The 12AX7 phase inverter gets hit with a hot signal from the preamp and being able to tame that signal before it. Both the volume and clean headroom will be reduced, yet the tone stays fairly the same (some clarity may be lost). This effect is similar to an attenuator, which is very nice when you want to achieve the amp's sweet spot at a lower volume. In a 2×12? @ 8 ohm speaker configuration, we recommend 4 ohm + 2 ohm output impedances Perceived Increase in Volume vs Actual Pot Resistance Properties of Linear pots Properties of Audio-Taper pots Replacing the stock master volume with an audio-taper is the best way to fix the oversensitive Master—as we can clearly see by the example above. If I remember correctly, the log pot on 4 is equal to the linear pot on 0.5! For those who don't know, twelve on the log pot is also as.
High gain amps such as Marshall or clones are hard on attenuators. Unfortunately, an amp's volume dial is not a good indicator of how much power is being produced. Many amps can reach full power at 3 or 4 on the volume dial, so it is a good suggestion to get an attenuator with 4x the power handling. For example, if you have a 50w high gain amp, you should opt for the MASS 200. If you have a. Metal Volume Box guitar amp audio taper effects loop master volume attenuator. $34.00. Free shipping.

An attenuator sits between your guitar amp head and your speaker, and serves as a post-power amplifier master volume. To use an attenuator, connect a speaker cable from one of your amp's speaker outputs to the attenuator's input, and then connect another speaker cable from the attenuator's output or through jack to the speaker cabinet's input jack. At this point, you can keep the. The output from my audio interface is balanced, as are the inputs to my powered speakers.

A guitar amp attenuator is a device that gets your tube-driven guitar amp to the edge of breakup at lower volumes. It does this in one of two ways: by using a power soaker to absorb a portion of the power and dissipate it as heat or via a power scaling circuit, which lowers the voltage available to the tubes, which allows distortion at a lower volume level

A stepped attenuator is geeky audio term for a complex multi-pole mechanical switch with a ton of resistors attached. It uses a big rotary switch to select discrete resistor pairs usually corresponding to a few dB change in volume per step. But it's still a mechanical device with multiple metal-on-metal contact points that can wear and corrode as well as introduce their own source of noise Cop-call-deterring boxes from Weber, Two Notes, Bugera, Radial, Mesa/Boogie, and more. Sure, you could simply roll down your amp's volume when you receive the evil eye (or worse) from your bandmates, engineer, spouse, or neighbor, but then your tonal sweet spot disappears. We've rounded up 10 attenuation options, from $50 to $550, that'll let you.
Every audio system needs at least one volume control, or attenuator. Since most audio equipment is stereo, the most common kind is a dual gang type, which bonds two attenuators together. Since our ears respond on a logarithmic scale, most audio attenuators have a log response, also called audio taper. After you narrow the field of commercial attenuators to the dual-gang audio-taper type, there really aren't that many choices available to the hobbyist. There is a. gain controls the amount of distortion is provided, volume controls preamp volume, master controls power amp volume punk isn't dead, it's always smelled that way.

Volume is a measure of the output of an audio system as measured in decibels (dB). You can think of a sound system as a set of speaker monitors, headphones, an airplane, a chainsaw, or someone whispering in your ear. A system in this case can be anything that produces sound. And the volume can be measured on the decibel scale. The higher the decibels, the louder the sound is. There's more to mention about sound pressure levels (SPL) and sound intensity, but let's not. When using a power attenuator with a tube amplifier, the master volume no longer acts as the master volume control. Instead, the power attenuator's attenuation control controls the power delivered to the speaker, and the amplifier's master volume control determines the amount of power-tube distortion. Power-supply based power reduction is controlled by a knob on the tube power amp, variously labeled wattage, power, scale, power scale, or power dampening What was lost with the Rothwells is the detail from the music. The sound lost its life, its direct sound, and its quickness. Taking the attenuators out of the loop produced improvement in some areas, but detriments in others. The sound without the attenuators was more detailed, snappier and more articulate. The leading edges of the music were better reproduced. The sound now regained some of its life, zest, snap and vibrancy. The soundstage also was larger and taller, generally bigger. The.
Attenuators also come handy when recording in small studios where cranking up your regular tube amp can be too loud. Note that even when using an attenuator, over-cranking your amp for prolonged periods will still cause faster wear and tear to the tubes - much like when the attenuator is not in use. So finding the right balance for the gain and attenuation level is important if you want to save your tubes Master Volume knob Down = no master volume at all, Up = master volume on. This diagram shows a 5E3 Deluxe but the push-pull switch wiring is the same. Another option is to use a switch and resistor for your master volume instead of a pot. You simply replace the master volume pot with a resistor on a switch. One guy used a 5k 1/2 watt resistor which gave him his preferred bedroom practice. The Volume Box lets you expand your amp's range of usable volume & dial in much more open & driven tube tones at lower/more manageable volumes (without driving your neighbors crazy!). It adds another much more responsive audio taper volume control to the circuit of your amp by simply plugging into the effects loop, no mods required whatsoever and no danger of harming your amplifier. It solves the problem of an EXTREMELY touchy volume knob on your amp, you know what I mean: zero has no. There are three kinds of volume controls when using a power attenuator in a standard setup. The first (gain) controls the amount of preamp distortion. The second (master volume) controls the amount of power-tube saturation and output transformer distortion. The third (attenuation) controls the amount of power sent through to the speakers, as opposed to being sent to the dummy load; this controls speaker distortion and room volume level The JTS Mic attenuator MA-123 works perfect for me in -30 dB setting. Very good price compared to the others. Quality and flexibility in settings: -10 / -20 / -30 dB. The Setup: ADI-2 DAC as preamp for the poweramp section of Accuphase E-600 (30W Class A).

The Volume and Master Volume might be on different sides of the fx loop (don't recall for certain, offhand). The attenuator is used slightly differently -- the Valvetronix' final amp isn't pushing into the dummy load so hard that that amp stage distorts; the power-tube distortion is generated earlier. It's like running a tube amp into a soak without driving the tube amp's power stage hard. The Ironman II reactive power attenuator gives Tone King amplifiers increased flexibility for any gig, session, or rehearsal. Just crank your amp to the sweet spot then reign in the volume for thick, rich tone at usable levels.

This means the overall volume level can be reduced, whilst keeping control over the entire amp's clipping characteristics. Unlike a loadbox, our design ensures the all-important relationship between the output transformer and the speaker remains intact so, even at very low volumes, the amp remains springy and responsive.
