Audio sensing.
Each – and + speaker terminal will accept bare speaker wire up to AWG 12, a wire terminated
with a
1
⁄4” spade lug, or with a single banana plug; dual banana plugs which are
3
⁄4” (19mm) apart
may be used for each speaker.
If you use bare wires, remove only enough insulation, about
1
⁄2” (12mm) for each exposed bare
wire to insert through the small hole in the side of the binding post. Before inserting a bare
wire, twist the strands tightly between your fingers to prevent strays that might touch the
chassis or another terminal and cause a short circuit. If you have soldering experience you may
want to “tin” the stripped bare wire with solder for a cleaner termination and to prevent the
wire from oxidizing.
Correct Speaker Polarity is Important
As you connect the speaker wires, you can see that the insulation on one of the two wires in
each pair has either printing or a raised ridge. The marking lets you know which wire you con-
nected to the positive speaker terminal at its other end.
Make sure the + wire you attach to each Model 5125 v.2 + speaker terminal is attached to the
+ terminal of the speaker for that channel.

• Manually, by pressing the Power button on the front panel.
• Automatically, when a suitable trigger voltage is applied to its 12V In (input) jack.
• Automatically, when an audio signal is present at the channels 1 and 2 audio Input jacks.
