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 ter-

minals 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 ter-

minal 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.

 - The vX Se

ries

 amplifiers have one XLr jack for balanced input per channel. use this connection to connect the output signal 

from a mixer, cross-over or EQ to your VX Se

ries 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. 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.
