Voltage Gain:
Gain Loop Out Headphone output (1,2,3)
Bal. Line -3 dB 34dB
HP Input -1 dB 35 dB
Output Clipping Level: +18dBu minimum with 600 ohm load
+16dBu minimum with 300 ohm load
Headphone Output impedance: 200 ohms
Input Clipping Level:
XLR:+24 dBu
Dynamic Range: ≥120 dB (Balanced line inputs)
THD + Noise: 0.03% maximum(from 10Hz – 22kHz @ +10 dBu input and output level, 300 ohm
load,10 Hz – 22kHz filter bandwidth)
Inputs: XLR: electronically balanced, 22k ohm input impedance
1/4-inch unbalanced: 9.1k ohm impedance
1/8-inch unbalanced: 9.1k ohm impedance
Note: only one set of inputs (balanced or unbalanced) should be connected at a time
Loop Output: Unbalanced, 200 ohm output impedance
Internal Voltage Rails ±15V, regulated
Power: Internal: 2 AA alkaline batteries, 12 hours life typical driving one 75 ohm headset
External: 5-17 VDC via threaded coaxial connector,(5.5mm outer diameter, 2.1 mm
inner diameter), pin positive, sleeve negative. Voltages above 17 VDC cause no
damage to unit, but will open an inter- nal poly fuse. Poly fuse will reset when voltage
is removed.
Power LED: Green indicates power and good battery.Red indicates power with low batteries. LED
turns red when approximately 4 hours of battery life remain
