Electronically balanced, Phoenix-type inputs are provided on all channels. Follow the +,– and Ground labels when
connecting the input signal.
If an unbalanced connection is desired this can be achieved by summing the minus (“COLD”) and Ground
terminals and using the + terminal as the “HOT” signal. For the best possible performance, the summing of ground
and minus wires should be done at the source unit end of the cable (e.g. a CD player).
Connectors are supplied for attaching cables to the inputs. Compatible input connectors are Phoenix Contacts,
Part number MSTB 2.5/3-STZ-5.08 , or Anytek OQ03545100CCG.
When linking the same source signal to several input channels, be aware that there is a limit to the number of
channels an output source can “drive”. A typical output source (e.g. a DSP crossover unit) can drive up to four
amplifier channels before line-drivers would be required to boost the signal.
13.4.2. Output operation and connection
Detachable block-connectors with + and – poles are provided at each channel output for connection of the
speakers. If more conectors are needed, then these are compatible:
Phoenix 1709047, or Anytek KT02015000CCG.
Make sure that the speaker cables are connected correctly and tightly, and that accurate polarity is maintained to
all speakers in the system.
As the amplifier outputs produce high voltage, do not connect or disconnect speaker cables when the mains
power is on.
