CONNECTIONS: OUTPUTS- USING THE TERMINAL BLOCK CONNECTORS
The output connections are made by attaching speaker
wires to the 8-pin terminal block connectors. Once these
connectors have been populated with the necessary
speaker wire connections, plug the terminal blocks into
their respective output jack.
The output jacks are configured in two discrete connectors.
One connector carries the connections for channels 1
through 4. The other, channels 5 through 8. Each connector
has 8 pins, each of which connects to the speaker wire
using a screw-clamp. Refer to the diagram, right, for the
basic connection procedure. Be sure that speaker polarity is
maintained. The locations of the + and - terminals on
the amplifier is not the same for each channel.
Ensure that all wires are neatly terminated with no loose
strands. Do not strip the insulation back excessively. Loose
strands and exposed wire beyond the terminals may cause
a short circuit and cause protective muting of the amplifier.
Once all the required connections have been made to the
terminal block connectors, they may be inserted into the
OUTPUTS jack on the rear panel. Orient the connector
properly (it only fits one way) and push it in until it is fully
seated in the receptacle. Note each connector is oriented so
its wires face outwards.
OUTPUT TERMINAL SAFETY WARNING!
Do not touch output terminals while amplifier power is on.
Make all connections with amplifier turned off. Risk of
hazardous energy!
How to make connections to the terminal block:
1- Strip the wires approximately 0.28” (7mm).
2- Twist any loose strands of wire together.
3- Loosen the appropriate retaining screw fully.
4- Insert the stripped wire into the receptacle.
5- Tighten the appropriate retaining screw to secure.
When selecting speaker cable (wire), always use the
largest wire size and shortest length of wire practical for
an installation. Larger wire sizes and shorter lengths
minimize power loss and degradation of damping factor. Do
not place speaker cables next to input wiring.
