12 V Loop Out Jack

The Trigger Out jack lets you loop or “daisy-chain” the incoming trigger voltage to an additional JC 1+ or other

component(s). The total load on your triggering device’s 12 V output is the sum of the trigger current drawn by

each of the components you plan to loop together. Check the maximum capacity of your preamplifier’s trigger

output so you do not overload it by connecting too many power amplifiers. Typical preamp trigger outputs are

rated to handle 50 mA to 100 mA.

3.5 mm and 2.5 mm jacks

Some other Parasound power amplifiers and preamplifiers might use a 2.5 mm “sub-mini” (mono) trigger jack.

To use the JC 1+ trigger with products that use a 2.5mm jack you will need a 3.5 mm to 2.5 mm mono adapter

for one of the plugs on the included trigger wire.

Front Panel Operation

On-Off Button

Push once to turn the JC 1+ on. Push the On-Off button again to turn the JC 1+ off. The On-Off button will be

disabled when the Turn On Options switch is set to Audio or 12 V. Whenever the JC 1+ is turned on, the soft

blue glow behind its On-Off button changes to red for a few seconds while its internal circuits stabilize. Then the

red glow is replaced by a brighter blue glow to indicate normal operation. If the glow remains red after turn-on or

while the amp is playing, it indicates activation of the JC 1+’s protection circuits and no sound will be heard from

the speakers.

The JC 1+ protects itself from external conditions such as excessive heat, load impedance that is too low, or a

short-circuited speaker connection or wire. After you correct the fault, the JC 1+ will resume operation. If the JC

1+ remains in “protection mode” (with a red glow around the On-Off button) after it has cooled down and you’ve

confirmed there are no external faults, it could indicate an internal problem. Please contact your Parasound

dealer or Parasound’s Technical Service Department.

Channel Indicator

When the blue channel indicator is lit, the JC 1+ is operating normally. If the indicator does not light, even

though the amp is turned on, there is a fault in your system. In the case of a fault first check that there is no

short circuit with your speaker wire or speakers.

Hi Temp Indicator

This indicator is near the right side of the front panel recess. It will glow red if the JC 1+ overheats. The On-

Off button will also glow red if the JC 1+ overheats. If such a condition occurs you must provide for better

ventilation around the amplifier or check the speakers for faulty operation that is causing the JC 1+ to

overheat. You might find you need to set the Bias switch to the Low setting to reduce heat output.
