Dual volume controls on superphon pre-amp

It replaces the need for a balance control.

If the two controls are for the two channels it is a damn nuisance. When stereo was first introduced I, and some others, used two mono preamps, because there weren't any stereo ones. I stacked two Heathkit preamps, installed a stereo volume control in one of them and ran the signal from the other preamp up and back.

Some preamps (but I haven't seen any lately) had, for each channel, volume controls at the input and at the output. This lets you optimize the signal level going through the circuitry. My electronic crossover, Ashly, has this feature today, and I use it to allow a high signal level through the digital circuits of my Behringer DEQ2496 equalizers without overloading the crossover or power amps.

Brilliant. Never would have thought about that. If that was the case the designer would have not put an extra control on what is a pre designed to be basic.

Any other ideas?

I have dual volume controls on my Morrison Audio ELAD. It seems like a pain, but I became acclimated to it pretty quickly. Try it for a while.

If it is the dual mono model it does replace the balance...but when stan warren designed it the were mirror image channels so neither channel relied on the other.I really enjoyed mine back then.replaced with higher end vol atteuators bumped it up another level.paired with a bk st-140.Those were simpler days.still think alot of that little preamp...
