3. Turn the module gain pot down counter clockwise (Left direction). 4. Turn EQ pot clockwise (Right direction). 5. Turn the AA120M power switch off. 6. Carefully inset the AA-SMG module into the card guider rails. Push until card is seated and the panels are flush. Secure with screws. 7. Select the AA120M input module mode, switch #5 located on the rear panel of the amp. 8. Turn all levels down on amplifier. Note if the module is in Amp Direct mode, the only level control you have for masking is the Gain pot on the AA-SMG. The Master and Input 6 levels on the AA120M are bypassed. All other channels operate normally. 9. Turn the amp on. You should be hearing either White or Pink noise. 10. Whenever connecting the Line Out or Insert jack, always turn off the AA120M prior to connection. 11. Tune the system as needed. Always a good suggestion to refer to Atlas’s white paper on masking.
