A Level control is provided for each channel.These level
controls are located on the back panel, providing a mea-
sure of security against unauthorized system changes.
The Dual/Mono switches are located on the back panel
below the level controls. Mono mode combines the two
amplifier output channels selected into a single mono chan-
nel with twice the voltage of a single channel. This means
¥
the output will be much more powerful! It does this by bridg-
."
ing the outputs, and it requires special output wiring. Do
NOT use the black (negative) outputs when the Mono
mode is selected. Connecting anything to the negative
terminals may result in polarity problems. When Mono mode
is selected, only the odd-numbered channel's level control
will work.
