AT&T 0II722050-917 Level Controls

Level Controls Main Output
Adjusts level of output. Full counter-clockwise rotation provides
unity gain from Telephone input to PagePal output. This is best
for driving AT&T PagePals, or consumer (home Hi-Fi) type
amplifiers.
Full clockwise rotation provides 14dB gain.* This will be more
appropriate commercial-industrial sound equipment. Refer to
the specifications of your power amplifier for the appropriate
input level, or experiment with the adjustments for best results.
Set the Main Output level first using telephone input, then
adjust Attendant and Music inputs for an appropriate relative
level. (Telephone input signals are typically -15 to -10dBm.)
Attendant Input
Adjusts level of Attendant Input relative to the Telephone Input.
Adjustment range is from 0dB to less than -30dB.
Music Input
Adjusts the level of Music Input relative to Telephone Input.
Adjustment range is from 0dB to less than -30dB.
*Gain assumes that the balanced output is driving 600 ohms. (See block diagram in Appendix B for gain
structure.)
