NOTES CAUTION: RISK OF ELECTRONIC SHOCK! DO NOT OPEN! TO PREVENT ELECTONIC SHOCK, DO NOT REMOVE TOP OR BOTTOM COVERS. NO USER SERVICABLE PARTS INSIDE. LEAVE SERVICING TO QUALIFIED SERVICE PERSONNEL. DISCONNECT POWER CORD BEFORE REMOVING BACK PANEL COVER TO ACCESS. MAGNETIC FIELD: Do not place sensitive high-gain equipment, such as pre-amplifiers or tape decks, directly above or below the unit. Because this amplifier has a high power density. It has a strong magnetic field which can induce hum into unshielded devices that are located nearby. The field is strongest just above and below the unit if an equipment rack is used. We recommend locating the amplifier (s) in the bottom of the rack and the pre-amplifier or other sensitive equipment at the top. WARNING! TO REDUCE THE RISK OF ELECTRIC SHOCK, DO NOT EXPOSE THIS EQUIPMENT TO RAIN OR MOISTURE!

Set up and Capabilities: 1. Mixer inputs: • Permits connection of up to 8 audio sources and two microphones • Connect audio sources such as CD players, Cassette players, VCR, electronic instruments (drum machines, keyboards, etc) to the line inputs • Phono 1 and Line 1 use the same input connectors • Phono 2 and Line 3 use the same input connectors • When not using Phono 1 or 2, place switch input selector to line position on the input panel (rear panel) 2. Connecting Turntables: • Connect up to 2 turntables to the phono 1 and 2 inputs RCA connectors • Input selector on the rear panel should be in the phono position 3. Connecting mixer outputs: • In order to run signal through a speaker system, you need to connect the master left and right output (amp output) to a power amplifier • This output will be controlled by the master fader • Amp output features two types of connectors (RCA or 1/4” jack) • Do not use both simultaneously 4. Connecting zone output: • Zone output is an extra master output • in order to run signal through a second speaker system, you need to connect the zone left and right outputs to another power amplifier • This output is controlled by the zone fader. • Zone output features stereo RCA connectors 5.
