  • Designed for high-definition field production environments, the studio-quality MP-1 is an ideal line-driver for critical radio, television, and film applications. The MP-1 is extremely durable and easy to use. With rugged mechanical and electrical construction and high-quality components it will provide years of superb audio performance under the most punishing field conditions.


    • Superb audio specifications
    • 66 dB of gain, in eleven discrete steps
    • Transformer-balanced input and output
    • Phantom power - 48 volt or 12 volt
    • High pass filter @  80 Hz or 160 Hz, 6 dB/octave
    • Limiter makes unit virtually "unclippable"
    • High current line output drive
    • Excellent immunity to RF interference.
    • Battery power (two x AA)
    • Durable mechanical construction
  • Equivalent Input Noise -126 dBu (-128 dBV) maximum (150 ohm source, flat weighting, 22 - 22 kHz bandwidth, gain control set at 50% or higher, phantom power off)
    Output Clipping Level (Line) +22 dBu minimum with 100k ohm load, +20 dBu minimum with 600 ohm load
    Dynamic Range 110 dB minimum
    THD + Noise 0.05% maximum (from 60 Hz to 22 kHz @ +4 dBu output level, 22 Hz - 22 kHz filter bandwidth, gain control at 50%, phantom off)
    Inputs Transformer-balanced, 2k ohm input impedance
    Outputs (XLR) s/n < 0507 - impedance-balanced, 120 ohm output impedance, s/n >0507 - active-balanced, 120 ohm output impedance
    Outputs (Tape) Unbalanced, tip-left, ring-right, sleeve-ground, 2.4k ohm output impedance
    Power (Internal) 2 AA alkaline batteries, 6 hours life typical with +4 dBu signal into 600 ohms, no phantom power
    Power LED Green indicates power and good battery. Red indicates power and low battery. LED turns red when approximately 1 hour of battery life remain (with phantom power off). Green with external DC power.
    Frequency Response 20 Hz - 30 kHz, +0.1, -0.5 dB; -1 dB at 5 Hz & 50 kHz (relative to 1 kHz with 150 ohm source, gain controls set at 50%)
    Input Clipping Level -10 dBu minimum
    Output Clipping Level (Tape) +11 dBu (2.75 V RMS) minimum with 100k ohm load
    Common Mode Rejection Ratio 100 dB minimum at 80 Hz, 60 dB minimum at 10 kHz
    Channel Separation Greater than 80 dB at 1 kHz (gain controls set to 50%)
    High-Pass Filters 80 Hz or 160 Hz (switch selectable), 6 dB per octave
    Phantom Power 48 V through 6.8k resistors or 15 V through 680 ohm resistors (switch selectable)
    Limiter Thresholds adjustable per channel from -10 dBu to +17 dBu, 10:1 limiting ratio, 5 mS attack time, 100 mS release time, Amber/Red LED indicates limiting/clipping, Dual mono or stereo linked
    Internal Voltage Rails ±15 V, regulated
    Polarity All inputs to all outputs, non-inverting. Pin-2 of XLRs "hot" to unbalanced inputs and outputs.
    Metering Seven segment GaN (Gallium Nitride) LED meter with three intensities, peak responding
    Operating Temperature Range 0 to 70 degrees C, 32 to 160 degrees F
