2.5 Output Connections
Because the current flow in constant voltage systems and speakers is
much lower than in 8
Ω
systems, higher gauge (thinner diameter) wire
can be used. Please refer to the following chart to choose the appro-
priate wire gauge for your installation.
Speaker leads connect by means of the removable 5mm terminal block
connectors supplied with the unit. Strip speaker leads 1/4” and insert
leads into connector observing proper polarity. With a small, flat-blade
screwdriver, tighten the screw until the leads are held securely in
place. Inspect for possible shorts or broken wires.

Note: Class 2 wiring must be used on the speaker termi-
nals to comply with UL requirements.
CAUTION: Do not connect either speaker terminal to
ground. This will cause a short circuit which may dam-
age the amplifier, speaker, or both.
CAUTION: The speaker terminals represent a shock haz-
ard as they carry 70.7V and 100V when driven with an
audio signal. Disconnect the amplifier from the AC pow-
er source when working on these terminals.
