INPUTS -
The MS series amplifiers allows you to use two types of input connectors, XLR female jack for balanced connections and 1/4” TRS female jack that
will accept balanced and unbalanced connections. Use these connections to connect the output signal from a mixer, cross-over or EQ to your MS series
amplifiers. 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 amplifier. 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.
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.
