FEATURES
1. ¼” THRU-PUTS: Left and right parallel outputs used to
connect the hi-Z instrument signal to an amplier, tuner or
personal monitoring system.
2. ¼” INPUTS: Left and right unbalanced, hi-Z inputs used to
connect instruments.
3. -15dB PAD: Reduces the input sensitivity to prevent overload.
4. +48V: LED indicator will glow when the J48 Stereo is
receiving phantom power.
5. HPF: High-pass lter switch gently rolls off bass to remove
rumble and resonant feedback (-3dB @ 80Hz).
6. BOOKEND DESIGN: Creates a protective zone around the
switches and connectors.
7. 180° POLARITY (side panel): Reverses the polarity of the
RIGHT XLR output by toggling pins-2 and 3.
8. I-BEAM REINFORCED: 14-gauge steel enclosure with rigid
I-beam construction makes it impossible to torque the PC
board and cause solder joints to go cold.
9. XLR OUT: Left and right balanced, low impedance mic level
output. Wired to AES standard (pin-2 hot).
10. GROUND LIFT: Disconnects the ground from the audio
signal path and helps eliminate hum and buzz caused by
ground loops.
11. NO SLIP PAD: Provides electrical and mechanical isolation
and keeps the J48 Stereo from sliding around.
12. POWDER COAT FINISH: Durable nish keeps your J48
Stereo looking great for years.
