Passive input selector and volume control
(power supply not required)
|Passive input selector + convenient volume control
If you do not listen to LPs, this selector is the best performing passive “pre-amp” for the money.
There are two stereo OUTPUT circuits to connect to power amplifiers.
REC output is fixed and not changed by the volume control.
You can connect a high quality amplifier to this passive “pre-amp” input selector and volume control chassis rather than purchase an expensive preamplifier; the only input source that won’t be available directly is for phono /LPs.
How to choose the volume control resistance (10k or 50k)
Please be careful about the gain of the power amplifier.
