Features

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.

Highlights

  • 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 @Ê 80 Hz or 160 Hz, 6 dB/octave
  • Limiter makes unit virtually "unclippable"
  • High current line output drive
  • Excellent immunity to RF interference
  • Durable mechanical construction
