MC20/30/50/70 inputs
Connect the audio source to the required
input, and make sure the selector switch is in
the correct position: up for balanced voltage
input; down for unbalanced voltage input.
Balanced voltage input:
High impedance: suitable for a standard
preamplifier or CD player for example. XLR
output.
Input impedance: 10 kohms + 10 kohms.
Unbalanced voltage input:
High impedance: suitable for a standard
preamplifier or CD player for example. RCA
output.
Input impedance: 10 kohms.
Connecting loudspeakers
There may be voltages
present at the loudspeaker
terminals which may present
an electric shock hazard if
touched. Always ensure the
unit is switched to OFF or
Standby mode when
connecting or disconnecting
loudspeakers.
Each amplification module is numbered and
named (15) for your convenience. To ensure
peak performance, and share the load equally
between the power supplies, we recommend
you connect the speakers as designated by
name. For example, connect the Left Front
speaker cable to 'L.Front' on your
MC20/30/50/70. (Refer to the diagram on
following page.)
Each amplification module has two
loudspeaker terminals (11):
•
Positive
+
(red)
•
Negative -
(black)
To connect the loudspeakers, connect the
positive (red) terminal of the multi-channel
power amplifier to the positive (red) terminal of
the designated loudspeaker. This will ensure
correct phasing of the audio signal. We
recommend only one loudspeaker be
connected to each amplifier module. Ensure
the loudspeaker terminals are securely
tightened, but do not over-tighten to the point
of damaging the connection.
,
Use only loudspeaker cables with well-
insulated terminals.
DO NOT SHORT-CIRCUIT THE TERMINALS.
