E AC Input Use the included power cord to connect your amplifier to an AC power source. F Master Power Switch Turns the current to the amplifier on or off. NOTE: The picture below is an AT2007 seven-channel model. It differs from the AT3007 only in the extra space on the panel. Other models ranging from two to six channels will only have two to six sets of balanced audio inputs, unbalanced audio inputs and speaker outputs. 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. When making connections with RCA type plugs or XLR connectors on interconnect cables, make certain to gently, but firmly, insert the plug into the jack and make sure that they are firmly seated. Loose connections can cause intermittent sound and may damage your speakers. Some quality plugs may be very tight, and it is important to assure a proper connection between the interconnection cable and the input jack. Be careful to match the type of input you have decided to utilize on your amplifier with the same type on your preamp or other source device. Do not mix types, i.e. do not use an RCA type jack on one end and an XLR connector on the other as this will defeat the output. Once you have chosen the type of connectors and made the connections, be sure that the small toggle switches located between the RCA and XLR jacks are thrown toward the connector being used. There will be no output if the toggle switches are in the wrong position. NOTE: There is an XLR pin assignment diagram located just above the binding posts for Output-1. Make certain that the cables/ connectors you choose utilize the same order of wiring to your preamp or other source device...they may be different. Failure to ensure this continuity will result in a malfunction. Please consult with your dealer if there is any doubt. Speaker Connections To assure that the high quality signals produced by your amplifier are carried to your speakers without loss of clarity or resolution, we recommend that you use high quality speaker wire. Many brands of wire are available; the choice may be influenced by the distance between your speakers and the amplifier, the type of speakers you use, personal preferences, or other factors. Regardless of the brand or type of speaker wire selected, we recommend that you use a wire constructed of fine, multi-strand copper with a gauge of 14 or less. In specifying wire, the lower the number, the thicker the cable. Wire with a gauge of 16 may be used for short runs of less than twenty feet. We do not recommend that you use any wires with an AWG equivalent of 18 or higher due to the power loss and degradation in performance that will occur. To connect the amplifier to your speakers, a pair of binding posts is provided for each channel output. These posts will accept bare wire, spade lugs or banana type plugs. If bare wire is used for the connections, strip approximately 1/2 inch to 3/4 inch of insulation from the end of each wire and carefully twist the strands of each conductor together. Be careful not to cut the individual strands or twist them off. All strands must be used for optimal performance. Correct polarity connections are important to maintain proper speaker phasing. When speaker phasing is correct, all speakers move in and out at the same time, preserving the imaging of the program material. Out-of-phase connections mean that some speaker cones will be moving in, while others move out. This will cause indistinct or confused imaging, and muddled and cloudy sounds. To avoid incorrect phasing or polarity, be certain to use wire that has distinct markings, colors, stripes, wording, or grooves on each side of the speaker cable. When making connections to the amp and speakers, adhere to a consistent pattern of using one side of the wire to the red terminals and the other side to the black terminals. When using cable with markings on one side only, traditional convention is to consider the marked side of the wire as the red, or positive (+) connection, and the non-marked side as the black or negative (–) connection. Next, loosen the knobs of the amplifier’s speaker output terminals, far enough so that the pass through hole is revealed. Follow the proper connection instructions for your system with regard to which terminals are used. Once the connections are made, twist the cap back so that the connection is secured, but do not over tighten or use tools, as this may break the delicate wire strands and decrease system performance. If you are using spade lugs, connect them to the speaker wire using the manufacturer’s instructions, and then loosen the caps on the speaker terminals. Place lugs between the plastic cap and the back of the terminal. Be sure to observe prope...
