AT&T 0II722050-917 installation manual Level Controls, Main Output

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.)
