Description
The MP-1: 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.
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.
Simple to Use
The MP-1 provides up to 66 dB of clean, nearly noiseless gain. Its transformer-balance microphone preamplifier offers a two-position highpass filter, extended range, selectable peak limiter, and 48 V phantom power, ensuring superior sonic quality and freedom from interference problems.

Tech Specs
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
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.
