[主要特性]
Frequency Response:
10 Hz-50 kHz, ±1.0 dB, any input to any output, gain control set to 50%

Voltage Gain:
(Gain, Loop, Out Headphone output) Bal. Line, -3dB, 34dB; HP Input, -1dB, 35dB

Output Clipping Level:
+18dBu m inimum with 600 Ω load
+16dBu m inimum with 300 Ω load

Headphone Output impedance: 200 Ω
Input Clipping Level: XLR:+24 dBu
Dynamic Range: ≥120 dB (Balanced line inputs)

THD + Noise:
0.03% maximum(from 10 Hz–22k Hz @ +10 dBu input and output level, 300 ohm load, 10 Hz–22k Hz 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 Ω output impedance
Internal Voltage Rails: ±15V, regulated

Power: Internal:
2 AA alkaline batteries, 12 hours life typical driving one 75 Ω 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
