Prior to using any Atlas Sound module please read the AA120M manual prior to use. It is very important for one to know the difference between Amp Direct and Mix Bus modes. KEY FEATURES 1. Gain Trim – When the gain is set to max (Clockwise), it is designed that the 70v output will not exceed 30v. When fully attenuated the module will have a 1v or less at the 70v outputs 2. EQ Trim– The EQ filter operating range is between 1 KHz and 8 kHz with a slope of 6db per octave. When the potentiometer is rotated fully clockwise the variable Hi-Cut filter is at 8 kHz. 3. EQ Insert – This TRS insert jack allows you to use an external equalizer for fine tuning of the system. Tip = Send to the EQ, Ring = Return from the EQ and Sleeve is the ground. 4. Line Out – This feature allows you use the generator to send a signal to another amplifier for multizone masking. You have the selection of two signal pick up points, Pre EQ or Post EQ. The Pre EQ is a fixed level of 250mv. The Gain, EQ or Insert jack have no effect on the Line Output. If Post EQ is selected, the Line Out signal is affected by the Gain level, EQ setting and the Insert Jack. In Post EQ mode the Line Out signal is the same signal that the AA120M is receiving. 5. Post or Pre EQ (jumper J11) – This is for the Line Out jack signal. To select this function, prior to inserting the module into the amplifier, locate (jumper J11) header and place the jumper to the desired selection. Note: You only need to move the jumper one pin over for connection. The middle pin is always connected. 6. Pink and White Noise selection (jumper J5)- Reposition the jumper for desired signal type. The middle pin is always connected. 7. Amp Direct and Mixed Bus (jumper J10) – This selection determines the master gain feeding the amplifier. It also works in conjunction with Input 6 module selection switch position 5 located on the rear panel of the AA120M. We suggest when using the AA-SMG module, the amp and module and AA120M are set to the Amp Direct position. The middle pin is always connected. 8. Out to Amp (jumper J8) – If you do not want the AA-SMG signal to go to the AA-120M and want to use the module to feed an external amplifier set this jumper to the OFF position.
