70V "Transformer-Coupled" Speakers
The Black Max series was designed to drive only 70V constant volt-
age type speaker loads. The use of low-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 out-
puts (A & B) is indicated with a "+" and "-" sign. Use these indica-
tors to ensure that the phasing of the speakers are 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 effected channel.

Note: The "+" and "-" indicators are mirrored on "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 done, but the amplifi-
er will go into protect mode and shut down the effected channel.

Inputs
Balanced Input Connections
Balanced input connections are used when the
source device provides a balanced output (sig-
nal "+", signal "-", and ground "G").This type of
connection is desirable when operating in elec-
trically 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 recommend-
ed.

Unbalanced Input Connections
When the source device provides only an
unbalanced output (signal and ground), the
input should be wired with "-" input shorted to
ground (G).The unbalanced signal's shield wire
is connected to ground and the signal hot wire
is connected to the "+" terminal. Since unbal-
anced connections do not provide the same
amount of noise immunity that a balanced con-
nection does, the connection distances should
be made as short as possible.
