Ground Lift
A ground lift switch is provided to further reduce noise caused
by ground loops.
Active Bandpass Filter
The analog fi lter section is the back-end of the reactive circuit
and its job is to emulate the typical response curve of a speaker
cabinet. The Class-A active fi lter in the JDX produces superior
sound over passive fi lter circuits.
Active Balanced Driver
The output driver in the JDX converts the output to a balanced 600
ohm mic-level signal for driving long cables without signal loss or
noise. This JDX output can be patched into typical microphone
snakes and be processed along with other microphone signals.
The active balanced driver uses a discrete Class-A design for
excellent headroom and low distortion.
180° Polarity Reverse
The polarity of the JDX output can be inverted with the 180°
switch. Depressing the switch will reverse the signal on pin-2
and pin-3 at the XLR output. The polarity reverse may be used
to interface older "pin-3 hot" equipment that does not follow the
AES standard for XLR pin-out, or to correct a polarity reversal
upstream in the signal chain.
Balanced XLR Output
The JDX outputs a balanced mic-level signal. The male XLR con-
nector pin-out is wired to the AES (Audio Engineering Society)
standard with pin-1 ground, pin-2 hot and pin-3 cold.
