10 Hz – 50 kHz, ±0.5 dB, gain at 50 %
10 Hz – 50 kHz, ±0.5 dB, gain at 50%
Greater than +30 dBu
80 Hz or 160 Hz (switch selectable), 6 dB per octave
12 V or 48 V (switch selectable), will supply 10 mA per DIN 45 596 specification
12 V via 180 ohm resistors, will supply 10 mA
Limits to +17 dBu output level, 10:1 limiting ratio
5 ms attack time, 100 ms release time
Amber/Red LED indicates limiting/clipping
±15 V, regulated
Internal: 2 x AA batteries
External: 5–17 VDC via threaded coaxial jack, (5.5 mm outer diameter, 2.1 mm inner diameter),
pin positive, sleeve negative.
Voltages above 17 VDC cause no damage to unit but will open an internal poly fuse. Poly fuse will
reset when voltage is removed.
All inputs to all outputs are non-inverting
XLR – pin-2 = hot, pin-3 = cold, pin-1 is ground
TRS – Tip = hot, ring = cold, sleeve = ground
