Gain Control

 – A gain control has been incorporated to adjust the level of the 

signal. Clockwise increases the signal. Note: When the gain is turn fully counter 
clockwise there will still be some signal present at the output.

5. 

EQ

 – This potentiometer allows one to adjust the noise parameter to meet a 

basic masking spectrum. This Hi-Cut filter adjusts from 7 kHz to 1 kHz at 6 db 
per octave. Note: If more equalization is necessary we suggest using an Atlas 
EQM131, a 31 band graphic equalizer, after the AA-GPN1200 balanced output. 
Note: For the EQ range control pot to be in effect, the EQ filter switch #6 must be 
in the POST EQ position. See the illustration showing the frequency curves to get a 
complete understanding of the EQ range.

6. 

Pre EQ & Post EQ

 – this slide switch allows one to select between Pre EQ and 

Post EQ. POST EQ, the internal Hi-Cut filter is engaged limiting the frequency 
bandwidth. In PRE EQ the internal EQ is bypassed allowing the full noise spectrum 
at the output. See illustration on the next page.

7. 

Balanced Output

 – This removable Phoenix style connector is a electronic 

balanced output. If an unbalanced signal is needed connect the (G) and the (-) 
terminals together.

Suggested optional accessory EQM131

 - For most sound masking systems the EQ 

on the AA-GPN1200 is adequate. For systems requiring more fine tuning of equalization 
we suggest using Atlas Sound EQM131.
