Sound Devices’ MP-1 is a portable, battery-powered microphone preamplifi er with phantom power. De-
signed for high-resolution fi eld production, this studio-quality mic pre is ideal for critical radio, televi-
sion, and fi lm production applications.
With its rugged mechanical and electrical construction, compact size and high-quality components, the
MP-1 will provide years of superb audio performance under the most punishing eld conditions.
Audio Performance
• Maximum of 66 dB of gain, adjustable in eleven discrete steps for accurate, repeatable gain set-
tings
• Dynamic range exceeding 120 dB
• 20 Hz to 50 kHz audio bandwidth
• High immunity to RF interference due to transformers, RF fi ltering, and all-metal construction
• High current line output driver capable of driving very long cable runs
Transformer-Balanced
• Premium quality input transformer provides superior sonic quality and freedom from interfer-
ence problems
• Custom-designed output transformer provides line driving ability with freedom from interfer-
ence problems
Limiter
• Extended range peak limiter via dual opto-isolators makes unit virtually “unclippable”
Battery Powered
• Internal battery power (two AA) for convenient, low cost power
• Battery life greater than 24 hours (phantom power off)
Durable Mechanical Construction
• High strength extruded aluminum chassis with protective metal end rails to withstand punish-
ing fi eld conditions
• Easy access battery compartment for quick battery changes
Phantom Power
• Selectable 48-volt and 12-volt phantom power for condenser and dynamic microphones
High-Pass Filter
• Two selectable corner frequencies, 80 and 160 Hz, 6 dB per octave
