Does such a preamp exist?


My pre simply has too much gain. I need a pre with 0 gain, but without the impedance problem of a passive;
So, this preamp has 0 gain input buffer, passive volume and sourse select network, then 0 gain output buffer...I wonder if this kind of pre exsists? If yes, please tell me, I want one badly...my volume knob keeps at 7-8 o'clock and already too loud.
Oh, one more thing, it must have balanced output...I know this is so difficult, I've searched everywhere and got no result.

For you information, unless you have an odd unit, your pre amp does have a gain control with a subtractive position(s), a unity gain position, and a amplified position(s). On my preamp, using an amp with a 1.5v input sensitivity, about 10 o'clock is unity gain for 1 source and 12 o'clock is unity gain for another.

What you need to do is to reduce the output gain by using in-line attenuators at the amp, say 12db, or see if your preamp mfg can reduce the output gain. What kind of pre-amp do you have?
The Levinson preamps like my 380S only apply gain when it is called for (about 19dB) based on the volume control position - from unity on down, the circuit actively buffers the inputs and outputs but applies no gain, and the sound does benefit. From what I've read, the forthcoming 320S will feature user-selectable gain including a 0 gain setting. All Levinson preamps of course are fully balanced with XLR I/O.
The Jeff Rowland Synergy preamps are balanced and have selective gain. Good luck.
Investigate at www.dact.com, splendid attenuators in balanced mode.

The site is worth a visit for didactical reasons too.
