Sound Devices MP-1 Portable Microphone Preamplifier

Sound Devices MP-1 Portable Microphone Preamplifier Overview: 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 Features: 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 Specifications: Frequency Response 20 Hz to 22 kHz, +0.1, -0.5 dB; -1 dB at 50 kHz (relative to 1 kHz level with 150 ohm source) Gain 0 dB to 66 dB input to output (switch selectable) Gain Accuracy +0.6, -0.1 dB with reference to front panel gain markings (150 ohm source, 100k ohm load impedances) Equivalent Input Noise -126 dBu (-128 dBV) maximum (150 ohm source, flat weighting, 22 - 22 kHz bandwidth, gain setting 36 dB or greater) Input Clipping Level +4 dBu minimum at the 0 or +18 dB gain setting Output Clipping Level +22 dBu minimum with 100k ohm load +2- dBu minimum with 600 ohm load Dynamic Range 122 dB minimum at the +18 dB gain setting THD + Noise 0.05% maximum (from 50 Hz to 22 kHz @ +4 dBu output level, +46 dB gain setting) Common Mode Rejection Ratio 100 dB minimum at 80 Hz, 60 dB minimum at 10 kHz Input Transformer-balanced, 2k ohm input impedance Output Transformer-balanced, 130 ohm output impedance Low Cut 80 Hz or 160 Hz (switch selectable), 6 dB per octave Phantom Power 12 V or 48 V (switch selectable) per DIN 45 596 specification Limiter Limits to +17 dBu output level 10:1 limiting ratio; 5 mS attack time, 100 mS release time; Amber/Red LED indicates limiting/clipping Internal Voltage Rails ±15 V, regulated Power 2 AA batteries, 24 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 4 hour of battery life remain Polarity Mic input to line output is non-inverting.
