1692a mixer

[valhallax]

hey folks..just got one of these and looking through the vault here, i couldnt find much on them. so im wondering, on the gain switches..54 db, 40 db, or 26db. do i feed a source into this and then measure the output for my amp? im running a few 9444s...

The 1692A is a mic/line mixer. It sounds like you are going to use it with a line input from a stereo source. Start with the input gain at the lowest setting. Set the output volume controls at 12 o'clock and slowly turn up the input controls. IMHO the gain is about correct when the input controls are between 9 and 2 o'clock and you are producing enough "loud".

I've got a PDF manual if you want it Jon. Just PM me your email addy if you do.

yep..ill be running an out, similar to the tape monitor function on a home stereo. ill have to get the dvm out and check source levels. i think its pretty cool having three levels of phatom power in a pre-amp. the manual says 81db's of output! recommended procedure is to set gain levels to preserve an optimum signal to noise ratio. average signal through the 1692a should be set with a vu meter at the +14vu(+18dbm)range (using program material).... now to rig up some rca-xlr wires and see how nice this sounds compared to my ol' samson pl1602 mixer

The 1692A offers phantom power on the inputs . . . Do not turn on the phantom power. Phantom power puts DC volts on the input terminals for powering condenser microphones. Line level sources will be damaged by phantom power. The 1692A offers multiple levels of input gain for a total of 81dB. Max output level is +18dB. Average output should be set for around 0dB to allow for peaks. Since the input of the 9444 power amplifier is 0dB for maximum power output, set the 9444 input level controls at 3 o'clock for approximately 12dB of attenuation. Large peaks in the program should barely illuminate the peak lights on the 9444 when you are running wide open.

Connect RCA-to-XLR;
Positive - RCA center - XLR pin 2
Negative - RCA shell - XLR pin 3
