Fully variable potentiometer, used to set the input sensitivity for channel-A.
Switches input impedance from 10 meg Ω for piezos to DRAG control for magnetic pickups.
LED indicator lets you know 48V phantom power is activated.
High Pass Filter eliminates excessive low frequency mud that can cause resonance and acoustic feedback on stage.
Channel selector switch, toggles between A and B inputs with LED status indicators.
Switches input impedance from 10 meg Ω for piezo transducers to 220k Ω for magnetic pickups.
LEDs show signal presence and if you are exceeding the maximum input level.
Adjusts the relative phase between channel A and B to time align fundamentals for a more natural sound.
Locking 4-pin XLR power connection for external power supply.
Balanced XLR connects to the PA and recording system.
Inverts the signal polarity by flipping pins-2 and pin-3 on the XLR output.
Disconnects pin-1 at the XLR out. Helps reduce noise caused by ground loops.
Introduces an isolation transformer into the XLR signal path to help eliminate hum and buzz caused by ground loops.
Extra high output for direct recording.
Hi-Z always-on ¼” output used to connect tuner.
Unbalanced ¼” thru-put used to feed the stage amp.
Unbalanced ¼” input jacks used to connect instruments to the JDV.
Connection point for the optional JR-2 remote footswitch.
Balanced ¼” TRS input for condensor or dynamic microphone.
Mic 48V Phantom
Turns on the 48V phantom power at the MIC IN.
Blend A+B in
Combines input-A with input-B and lets you mix the two sources using the front panel level controls.
Lets you introduce an isolation transformer into the stage amp output signal path to reduce hum and buzz caused by ground loops.
