C Connect the sleeve to ground (Gnd). Connecting the sleeve to a negative
(-) terminal will damage the audio output circuits.
C The length of the exposed (stripped) portion of the copper wires is
important. The ideal length is 3/16” (5 mm). Longer bare wires can
short together. Shorter bare wires are not as secure in the direct insertion
connectors and could be pulled out.
The volume level for each output can be individually set via the front panel
or Ethernet or serial port control. See chapter 3, “Operation”, chapter 4,
“Programmer’s Guide”, chapter 5, “Matrix Software”, and chapter 6,
“HTML Operation” for details.
