Correct Speaker Polarity is Important
Polarity refers to + and – connections. Speaker wires are coded with color, printing or a ridge on the insulation
on one of the leads so you know which lead was connected to the + and – terminals at the other end. This
coding will help you keep the + and - polarity consistent for all channels. If one speaker is wired with incorrect
polarity it will significantly impair sound quality.
Speaker Wire Length and Gauge (thickness)
When selecting speaker wire, follow these guidelines:
• Keep the length of your speaker wire as short as possible.
• Use the thickest wire practical. For lengths greater than 50 feet, use speaker wire with an
AWG (gauge) of 14 or lower. The smaller the AWG number, the thicker the wire.
Turn On Options
The setting of the rear panel Turn On Options switch determines how the amplifier turns on and off.
Setting the Turn On Options switch to Audio or 12
V disables the JC 5’s front panel Power button.
There are three positions for this switch:
Manual:
When the Turn On Options switch is set to
Manual
the JC 5 is
turned on and off manually only by pressing the Power button on its
front panel every time you want to listen to music.
Audio:
When the Turn On Options switch is set to the
Audio
position,
the JC 5 will be turned on automatically when an audio signal is
present at the L or R Input jacks. After the audio signal ceases the
amplifier will remain on for about 10 minutes before shutting itself off.
This prevents unintended turn-off during pauses in your music...
12
V Trigger:
When the Turn On Options switch is set to its
12
V
position, the JC 5 is turned on and off only with an ex9 V to
+12
V DC voltage. When the external voltage ceases the amp will
turn off within a few seconds. The 12
V turn on trigger circuit in the
JC 5 requires a mere 5mA from the 12
V trigger source.
Turn On Threshold
This knob sets the audio signal level required for the JC 5 to automatically turn on when the Turn On Options
switch is set to the Audio position. Fully counter-clockwise is the most sensitive setting and therefore is
labeled “Quieter.” Fully clockwise requires a higher audio signal voltage and is therefore labeled “Louder.” In
most systems the best results will be with the Turn On Threshold knob set at or towards the Quieter position.
In some systems the JC 5 might turn itself on if there is a transient noise in the AC power line, even when an
audio signal is not present. Similarly, the JC 5 might never shut off even after waiting more than 10 minutes.
In this case, try rotating the knob towards the Louder position.
