The pin assignments of the Bravo amplifier XLR-type female
chassis input connector is
Pin 1: Signal ground
Pin 2: Signal + (non-inverting)
Pin 3: Signal - (inverting)
Connector ground lug or case: chassis ground
These pin assignments are consistent with the standards adopted by
the Audio Engineering Society. Refer to the operating manual of your
balanced-output preamplifier to verify- that the pin assignments of its
output connectors correspond to your Bravo power amplifier. If not,
wire the cables so that the appropriate output pin connects to the
equivalent input pin.
4. AC mains cord and AC mains switch
IEC standard power cords are used in the Bravo power amplifier.
Plug the cord into the high-current IEC outlet provided, and then into a
suitable wall outlet.
Your new Bravo power amplifier has been safety-tested and is
designed for operation with a three-conductor power cord. Do not
defeat the "third pin" or earth ground of the AC power cord.
Two fuses are located at the rear of the Bravo power amplifier. The
protection circuitry has been designed such that only a catastrophic
failure would cause these fuses to blow. As a result, if you suspect that
your AC fuses have blown, disconnect your amplifier from the AC
mains and check them.
Potentially dangerous voltages and current capabilities exist within
your power amplifier, even when disconnected from AC mains. Do not
attempt to open any portion of the amplifier's cabinet. There are no
user-serviceable parts inside your power amplifier. All service of this
product must be referred to a qualified VIOLA dealer or distributor.
