Connections
For 70V and 8-ohm Speakers
The 6XL was designed to drive 70V constant voltage and 8-ohm
type speaker loads. The use of lower impedance speakers may
cause the amplifier to engage its protection circuits and shut
down or limit amplifier function. The speaker terminals can
accept up to a #10 AWG wire or spade lug and have integral
clamping plates which make wiring easier. The polarity of each
set of speaker outputs (A & B) is indicated with a “+” and “-” sign.
Use these indicators to ensure that the polarity of the speakers is
correct. Do not ground the “+” output of either set of outputs.
Doing so will cause the amplifier to go into protect mode, shutting
down operation of the affected channel.
Note: The “+” and “-” indicators are mirrored on the “A” and “B”
outputs. Be sure to make the correct connections.
Earth Ground Terminal
The Earth Ground Terminal is provided as a convenient means
to connect to the amplifier’s chassis/AC ground, if necessary.
DO NOT connect the earth ground terminal to the “+” terminals
of either output. No damage will occur if this is accidently done,
but the amplifier will go into protect mode and shut down the
affected channel.

Balanced Input Connections
Balanced input connections are used when the source device
provides a balanced output signal (signal “+”, signal “-”, and
ground “G”). This type of connection is desirable when operating
in electrically noisy environments, where long input cable runs
are needed, or to ensure the lowest noise operation.
If compatible with the source device, this type of connection is
recommended.
Unbalanced Input Connections
Unbalanced input connections are used when the source device
provides an unbalanced output signal (signal “+” and ground
“G”). Since unbalanced connections do not provide the same
amount of noise immunity that a balanced connection does, the
connection distances should be made as short as possible.
