Portable, battery-powered microphone preamplifier with phantom power. Designed for high-definition field production environments, the MP-1 is an ideal studio-quality mic pre for critical radio, television, and film applications.

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)
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

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.

+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)
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
