INPUTS
The V1500™ allows you two types of input connector per a channel, a XLR jack for balanced connections and a 1/4” jack for
unbalanced connections. Use these connection to connect the output signal from a mixer, cross-over or EQ to your V1500 amplifier.
The XLR connection is recommended for cable runs longer that 20ft. When building 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” input option. The 1/4” input
option may be a little more convenient for most user due to the abundant supply of prefabricated cables on the market. You may
also use the two different types of input cables to jump a parallel connection to another amp. For Example: Connect a XLR cable
to the input of channel one. You may now connect a 1/4” cable to the input put jack of channel one and jump that cable to the
input of another amp.
