Use these connections to connect the output signal from a mixer, cross-over or EQ to your VLP 2500 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 connect by bare wire (directly connected, usually for permanent connections), banana plug, or spade connector. 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. Important Notice: Banana Plugs - When connecting your speakers to the amplifier using banana jacks; Be sure that the red and black caps on the binding post are completely screwed in. Insert the banana jacks into the caps of the binding post, be sure that the banana jack is inserted securely to avoid the risk of it popping out. Figure 6 ©American Audio® - - VLP 2500 Power Amplifier User Manual Page 7 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. Spade Connector: (Figure 8) When connecting your speakers to the amplifier using spade connector; Unscrew the red and black caps on the binding post, be sure not to completely remove or unscrew the red and black caps. Insert the spade connector in to the binding post and tighten the caps down on the spade connector. 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. When connecting your speakers to the amplifier using banana jacks; Be sure that the red and black caps on the binding post are tighten down completely. Insert the banana jacks into the caps of the binding post, be sure that the banana jack is inserted securely to avoid the risk of it popping out. 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. Figure 8 Typical speaker output using spade connectors. Insert bare wire into the binding post and tighten. Stereo Connections Using the Ne...
