Important Safety Instructions
1. Read these instructions.
2. Keep these instructions.
3. Heed all warnings.
4. Follow all instructions.
5. Do not use this device near water.
The lightning flash with arrowhead symbol within an equilateral triangle, is intended to alert the user to the presence of uninsulated “dangerous voltage “ within the product’s enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons.
The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the product.
6. Clean only with dry cloth.
7. Do not block any ventilation openings. Install in accordance with the manufacturer’s instructions.
8. Do not install near any heat sources such as radiators, heat registers, stoves, or other device (including amplifiers) that produce heat.
9. Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized plug has two blades with one wider than the other. A grounding type plug has two blades and a third grounding prong. The wide blade or the third prong are provided for your safety. If the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet.
10. Protect the power cord from being walked on or pinched particularly at plugs, convenience receptacles, and the point where they exit from the device.
11. Only use attachments/accessories specified by the manufacturer.
12. Use only with the cart, stand, tripod, bracket, or table specified by the manufacturer, or sold with the device. When a cart is used use caution when moving the cart/device combination to avoid injury from tip-over.
13. Unplug this device during lightning storms or when unused for long periods of time.
14. Refer all servicing to qualified service personnel. Servicing is required when the device has been damaged in any way, such as power-supply cord or plug is damaged, liquid has been spilled, or objects have fallen into the device, the device has been exposed to rain or moisture, does not operate normally, or has been dropped.

1. Power Switch This push on/off switch supplies power to the AA60 mixer amplifier.
2. Power LED
This LED illuminates when the power switch is turned on.
3. Peak LED Indicator
The PEAK LED will illuminate when the AA60 is in a clipping condition, caused by excessively high input levels or a GAIN control is turned up too high. An occasional flash is OK. Check that the proper signal level is being fed into the inputs and/or turn the input gain down until the LED is no longer illuminated.

4. Signal LED
When the signal LED illuminates, this indicates that input signals connected to the amplifier are capable of driving the AA60 to full power.
5. Input 1 Gain
Input 1 rotary control varies the amplitude of the signal fed into the amplifier. Turn clockwise to increase and counter-clockwise to decrease the signal level.
6. Input 2 Gain
Input 2 rotary control varies the amplitude of the signal fed into the amplifier. Turn clockwise to increase and counter-clockwise to decrease the signal level.
7. Input 3 Gain
Input 3 rotary control varies the amplitude of the signal fed into the amplifier. Turn clockwise to increase
and counter-clockwise to decrease the signal level.
8. Bass Control
Normally set at the 12:00 position, rotating clockwise will increase (boost) bass frequencies to a maximum of
10 dB at 100 Hz. Rotating counter-clockwise from the 12:00 position will decrease (cut) bass frequencies to a maximum of 10 dB at 100 Hz.
9. Treble Control
Normally set at the 12:00 position, rotating clockwise will increase (boost) treble frequencies by 10 dB at 10 kHz.
Rotating counter-clockwise from the 12:00 position will decrease (cut) treble frequencies by 10 dB at 10 kHz.
