The RDL HR-MP2A is a dual channel microphone preamplifier designed for professional audio applications.

The RDL HR-MP2A is a dual channel microphone preamplifier designed for professional audio applications. It features 40dB of gain with polarity switches and includes 1/4" TRS, terminal block inputs. The device supports two XLR inputs with an input impedance of less than 1kΩ balanced. For +4dBu output, the input level ranges from -56dBu to 0dBu (maximum gain without pad, minimum gain with pad). The gain range is adjustable between 20dB to 60dB for each preamplifier.

An input pad of 15dB nominal is available per channel. Outputs include three detachable terminal blocks and two 1/4" TRS phone outputs. The output impedance is 150Ω balanced, with an output level 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 +/-0.5dB flatness, featuring 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)
