The HR-MP2A from RDL is a dual channel microphone preamplifier housed in a half space rack-mount chassis. The preamp features exceptional input headroom, wide flat frequency response, and extremely low noise with very high common-mode signal rejection. Total harmonic distortion and crosstalk are below the noise floor.
Each section provides identical connections and controls. A 15dB pad and polarity inverse can all be enabled, along with 48V phantom power. A separate LED flashes when a signal peak is within 3dB of clipping. The HR-MP2A can be operated as a stereo preamplifier, or as two separate mono preamplifiers.
Balanced line-level outputs include detachable terminal block and 1/4" TRS phone connectors, which can be wired unbalanced. A separate summing amplifier provides a combined mono output on a line-level detachable terminal block, and a power input jack allows for connecting 24VDC power.
