Hey guys, I recently bought a beautiful Teac 5B mixer and am a little confused by the calibration process suggested in the service manual. Here is the manual for reference - https://usermanual.wiki/Collections...am Series 5, 5A Mixer Service Manual.pdf.html
In the 'Level setting and operation check' section of the manual, it says to apply a -10dB signal to the line in, and a level meter to the direct out, then raise the trim pot so that the level meter reads -10dB. Shouldn't a -10dB input give me a -10dB output without adding gain?
I calibrated the mixer fully according to the manual, and the result is this - when I play back something I recorded to tape, the signal coming in is much lower than the signal going to tape. So I have to turn up the gain on the receiving channel in order to match the level (which is consistent with the way it was calibrated, but it doesn't seem right to me!). Maybe I'm missing something or misinterpreted the manual somehow? Any help would be greatly appreciated.
