Specifications

Frequency Response: 10Hz-50 kHz,+/-1.0dB, any input to any output, gain control set to 50%

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
