Specifications

The C52 contains two identical subwoofer
controllers, Channel 1 and Channel 2. Unless
otherwise stated, this section refers to one
section only.
Output Connections
Connect the cables from the rear-panel output
terminals to the loudspeakers. Be sure to
observe correct polarity, and note that these
terminals can develop significant voltages/
current-passing capability when the C52 is
powered up and being fed with an active
signal. Ensure that connections are made
with the power disconnected from the
unit.
Digital connections
Identify the S/PDIF digital connections on the
rear panel as shown on the diagram above.
The Digital Input should be connected to
a digital source, such as a digital sound
processor, or digital preamplifier.
The Digital Output may be connected to a
second (slave) DSP loudspeaker, using an S5
lead.
The S/PDIF cable connected to the digital
input carries two channels. Set the DIGITAL
CHANNEL SELECTOR switches on the front
panel switch to indicate which channel(s) are
directed to each subwoofer.
