22. Channel 1 & 2 TRS Input - Channel one & two 1/4” female jacks. Excepts either a balanced or unbalanced plug. See page 9 for more details. 23. Mode Switch - This switch controls the amplifier’s operating mode. The amplifier can operate in three different modes; Mono Bridge, Stereo, or Parallel Mono. The amplifier is shipped in stereo mode. 24. Air Vents - These vents allow hot air to exit the amp. Do not place anything in front or obstruct these vents. 25. AC Cord - Plug this cable into a standard wall outlet. Check that the voltage in your area matches the amplifiers required voltage. 26. Fuse Holder - This housing stores a 15 amp protective fuse for the XLT1200 and 20 amp protective fuse for the 2000 and 2500. Never defeat the fuse, the fuse is designed to protect the electronics in the event of severe power fluctuations. Always be sure to replace the fuse with an exact match as the one being replaced, unless otherwise told to do so by an authorized American Audio® service technician. ©American Audio® - - XLT Series Power Amplifier User Manual Page 7 Set Up INPUTS - The XLT Series amplifier allows you to use two types of input connector per a channel, a XLR jack for balanced connections and a 1/4” female jack that will accept balanced and unbalanced connectors. Use these connections to connect the output signal from a mixer, cross-over or EQ to your XLT Series amplifier. A balanced connection is recommended for cable runs longer that 20ft. When constructing your own XLR cables follow the pin configuration describe below for proper connections. For cable runs shorter than 20ft. you may choose the 1/4” unbalanced input option. The 1/4” unbalanced input option may be more convenient for most users due to the abundant supply of prefabricated cables available at your local audio dealer.

The speaker wire may be connected by bare wire (directly connected, usually for permanent connections). Connections are made to Channels 1 and 2 output’s for stereo mode or across the red terminals of Channels 1 and 2 for Mono Bridge Mode. Important Notice: Although a speaker will operate with the positive and negative leads plugged into either terminal on the amplifier binding post, be sure to plug the negative lead into the black terminal and positive lead into the red terminal. Ensuring proper polarity will avoid speakers being out of phase, that can cause a loss of bass response. ©American Audio® - - XLT Series Power Amplifier User Manual Page 8 Bare Wire Connections: (Figure 7) When connecting your speakers to the amplifier using bare wire; Unscrew the red and black caps on the binding post, be sure not to completely remove or unscrew the red and black caps. Strip back the wire insulation 1/2” (13mm). Insert the bare wire into the hole that was reveled by unscrewing the binding post cap. After inserting the wire into the binding post hole, screw the binding post cap down on the wire. To reduce the risk of shock or damage to your amplifier, be sure that the wire connected to one binding post does not come in contact with that of another. Figure 7 Typical speaker output using bare wire. Insert bare wire into the binding post and tighten. Mono Bridge Connections: Mono bridge operation connections will follow the above descriptions however, when operating in mono bridge operation the speaker connections will run between the two positive (red) leads. Use channel two positive output terminal for the negative connection and the channel one positive output terminal for the positive connection. Stereo Connections Using the Neutrik Speakon output connectors: Recent regulatory requirements in Europe have outlawed the use of the dual banana plug and forced amp users to terminate their speaker cables with spade lugs or bare wire ends. This is not advantageous to most users that want to reconfigure their systems or quickly change out an amp. The Neutrik Speakon® connector provides the most convenient solution to this problem, eliminating the need for spade plugs or bare wire end cables. Major speaker manufacturers have been using Speakon connectors on their products for years, so chances are you are ready to use the Speakon connection. With Speakon connectors, you can connect straight from the amplifier to the speaker. The Speakon connector used on this amplifier meets all known safety regulations. Once wired correctly, the connector cannot be plugged in backwards, causing the type of inverted polarity situations that have become common with banana hookups. This connection will provide a safe, secure and reliable method of connecting your speakers to your new amplifi...
