American Audio V4000 plus manual Set Up, Outputs, Male XLR Pin Configuration, Balanc, RS 1/4” Plug

Set Up

INPUTS - The V4000plus 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 V4000plus 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. You may use the two XLR “Input Thru” jacks to jump a parallel connection to another amplifier or other device. For Example: Connect a XLR cable to the input of channel one. You may now connect a XLR cable from the channel one “Input Thru” jack to the input jack of another amplifier’s channel one input. This will reduce the use of “Y” cables.

OUTPUTS:

Binding Post/Banana Plug - Connect your speakers to the binding post outputs on the rear of the amplifi er. 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 termi- nals 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 termi- nal on the amplifi er 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 amplifi er using banana jacks; Be sure that the red and black caps on the binding post are completely screwed in.
