Nobsound high precision passive preamp volume controller
Fema test answers 200c
Volume control The volume control module is placed at the end of the digital signal path, just before the DAC. This ensures that all intermediate processes are performed with optimal precision. The volume adjustment process is performed by simple multiplication. If we want to reduce the signal level by 3dB we multiply each sample by 0.707.
SOLD - $ 150.00. This passive preamp is built using a Dact CT-2 100K Stereo 24 step Attenuator. Currently wired for One input and one output. But another set of output is available for hookup. You will just need to solder the wire if you need to use 2 pairs of output (making it useful for by-amping, etc).
