RDL HR-MCP2 – Dual Channel Microphone Compressor and Preamp
What is the RDL HR-MCP2?
The RDL HR-MCP2 is a two-channel microphone compressor that holds output levels consistent over input variations of up to 25 dB. Each channel can work as an in-line mic-level compressor or as a microphone preamplifier with compression and line-level output. It suits broadcast studios, voice-over rooms, public address systems, meeting rooms and commercial sound systems where talkers vary widely in level.
How does it work?
The HR-MCP2 installs between a microphone and a mixer or amplifier mic input, or serves as the microphone preamplifier itself. Rear-panel switches set each output to mic or line level. It works with dynamic and condenser microphones, and a front-panel switch enables 48 V phantom power on both inputs. Gain reduction is nearly instantaneous for expected and severe overloads, and automatic release adjustment keeps compression action nearly inaudible. Each channel has an 80 Hz low-cut filter switch and a 15 dB input pad that raises the maximum input level from +5 dBu to greater than +20 dBu. The gain control adjusts from 20 dB to 60 dB for the line output. A seven-LED meter shows gain reduction in 3 dB steps, and a CLIP LED flashes when a peak is within 1 dB of clipping. Inputs and outputs are balanced on XLR jacks and detachable terminal blocks, and channels can operate as a stereo pair or as two mono channels. The unit runs from 24 Vdc; RDL recommends its PS-24AS (USA) or PS-24AX (international) 24 Vdc supply. It operates free-standing on included feet or rack mounts with the HR-RA2 19-inch rack adapter or HR-HRA1 10.4-inch rack chassis.
What are the key features?
- Two compressor channels — Independent channels for dual mono or stereo operation.
- Consistent mic levels — Holds output level steady over input variations of up to 25 dB.
- Mic or line output — Rear-panel switches allow use as an in-line compressor or a preamp with compression.
- Phantom and pads — Switch-selectable 48 V phantom and 15 dB input pads.
- Gain reduction metering — Seven-LED meter in 3 dB steps plus CLIP indicators per channel.
- Low-cut filter — Switchable 80 Hz low-cut filter on each channel.
Where is it typically used?
- Broadcast and voice-over studios
- Boardrooms and meeting rooms
- Houses of worship
