REAR PANEL CONNECTIONS
It is easy to interface the SDA-1 with a wide variety of equipment. All inputs
and outputs are located on the rear panel. Standard ¼” and XLR inputs and
binding post outputs make patching simple.
Inputs
The SDA-1 has two styles of input connections: XLR and ¼”. Use
these connections to connect the output signal from a mixer,
preamplifier, crossover, or EQ to the amplifier. The balanced XLR
connection is recommended for cable runs longer than 20 feet. For
cable runs under 20 feet, the ¼” option may be preferable.
You may also use the two different types of input cables to jump a
parallel connection to another amp. For example: connect an XLR
cable to the input of channel one, then connect a ¼” cable to the input
jack of channel one and jump that cable to the input of another amp.
¼” Input Jacks
The ¼” Input jacks are wired as follows: Tip is positive, Ring is
negative, and Sleeve is ground. This connection can be used for both
balanced and unbalanced connections.
XLR Input Jacks
The XLR Input jacks are Pin Two positive, Pin Three negative, and Pin
One is ground. This connection is for balanced connections.
