Owner's Manual

Audio Output Connections

The JC 3 Jr. Output jacks connect to the line level input jacks on your line level preamplifier or

integrated amplifier. Each channel has one balanced XLR jack and one unbalanced RCA output

jack. If your line stage preamplifier or integrated amp is equipped with balanced XLR inputs we

recommend using the JC 3 Jr. Balanced XLR output jacks for the maximum rejection of external

noise sources. The balanced and unbalanced jacks are active simultaneously.

Auto Turn On Option

Turn On Options switch

This switch enables you to choose whether your JC 3 Jr. is turned on and off manually or

automatically, provided your preamp/line stage or integrated amp is equipped with a 12V

trigger output jack.

Note: Setting the Turn On Options switch to 12V disables the JC 3 Jr.’s front panel On-Off

button.

12 V In Jack for Auto Turn On

When the JC 3 Jr. Turn On Options switch is set to 12 V the JC 3 Jr. will turn On and Off

automatically with your preamplifier. The 12

V input is a 3.5mm (1/8”) mono mini jack. To

trigger the JC 3 Jr. on and off automatically, insert the trigger wire plug into this jack and plug

the other end into your preamplifier or integrated amp’s 12

V output jack.

Note: The JC 3 Jr. trigger circuit draws a negligible 10

mA current from the triggering device.

12 V Loop Out Jack

The Trigger Out jack lets you loop or “daisy-chain” the incoming trigger voltage to another

component.

AC Power Connections

AC Power Inlet & Power Cord

A high quality IEC-type AC power cord is supplied with your JC 3 Jr. Please connect it

directly to an AC wall outlet or power line conditioner that is always “live.” If possible, plug

your JC 3 Jr. into the same AC wall outlet or line conditioner that your line level preamplifier or

integrated amp is plugged into. If a different AC outlet is used for the JC 3 Jr. the ground

potential may be higher or lower between the AC outlets, resulting in audible hum.

Rear Panel AC Power Switch

This switch is provided to turn the JC 3 Jr. completely off when it will not be used for an

extended time. Normally, this switch is left in the “on” position (upper section is pressed in).
