The RDL HR-MP2 is a dual channel microphone preamplifier designed for professional audio applications.

The RDL HR-MP2 is a dual channel microphone preamplifier designed for professional audio applications. It features 40dB of gain and a 6dB/Octave low-cut filter for enhanced sound quality. The unit includes two XLR inputs with balanced input impedance below 1kΩ. The input level ranges from -56dBu to 0dBu, with maximum levels varying based on the input pad setting. Gain can be adjusted between 20dB and 60dB per channel.

Each preamplifier has a 15dB nominal input pad. Outputs include two XLR connections, three detachable terminal blocks, and two 1/4" TRS phone jacks. The output impedance is balanced at 150Ω, with output levels of +4dBu balanced, -4dBV unbalanced, and a maximum of +24dBu. Phantom power options include switchable 24V or 48V. The frequency response spans from 10Hz to 70 kHz with a flat curve, and includes a low-cut filter at 80Hz.

  • Number of Channels: 2 (1 and 2 may be used for stereo, or as two separate mono preamplifiers)
  • Inputs: 2 x XLR
  • Input Impedance: < 1kΩ balanced
  • Input Level: For +4dBu output: -56dBu to 0dBu (maximum gain without pad, minimum gain with pad) Maximum Level: >+5dBu input pad disabled, +22dBu input pad enabled)
  • Gain Range: 20dB to 60dB (front panel adjustable for each preamplifier)
