  • Thông số kỹ thuật :


    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)

    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

    Operating Temperature Range: 0°-70°C (32°-160°F)
    Dimensions (H×W×D): 43×94×140 mm(1.69"×3.7"×5.51")
    Net Weight: (unit only) 0.56 kg, 1.24 lbs
    Packaging: Colorful outer packaging
