Getting to Know the Rear Panel A. Balanced XLR Audio Inputs F. Master Power Switches Use the BALANCED INPUT jacks to connect to the outputs of a preamplifier or other control device with XLR outputs. Turns the current to each bank of the amplifier on or off. B. Input Selector Switch Selects either the BALANCED INPUT (XLR) or the UNBALANCED (RCA) INPUT jack. Use the REMOTE TRIGGER jack to connect to a compatible preamplifier, source device, or other product with a 3.3-24 VDC output. C.
Input Connections Connecting the amplifier to your source equipment is simple. Using high-quality XLR cables or audio interconnect cables, match the output channel designations on the rear of your source equipment to the balanced input jacks or unbalanced inputs jacks on the rear panel of your amplifier that have the same channel name.

Power Control Connections CAUTION! Your amplifier features a built-in remote turn-on system that will automatically switch the amplifier on when another device in the system is switched on. Never make or break connection to the 6000 series amplifiers unless the amplifiers and all associated components are powered off.
Main Circuit Breaker ATI Service Information Your amplifier is supplied with two heavy-duty magnetic circuit breakers/power switches. If power to your amplifier is interrupted, inspect the circuit breaker on the rear of the unit. If the circuit breaker is in the off position you may reset it to the on position to restore AC power. If the circuit breaker immediately trips to the off position, unplug the amplifier from the AC power source and contact the ATI Service Department.
A Few Words About Hum and Noise Audible hum, or a discernible low frequency noise, is one of the most common problems in audio/video systems. This hum, which may be present even when the volume is at a low level, is usually caused by a problem known as “ground loops”. A ground loop occurs when there is a difference in ground voltages between two or more components that are connected electrically. This, in turn, creates multiple current paths and causes the low-level noise, or hum.
