Application Spotlight

In this Application Spotlight we explain how automatic microphone level control will enhance a sound system’s intelligibility.? This is ideal for any venue that supports untrained presenters (i.e., public speakers) or multiple presenters with a wide variety of speaking styles ranging from overly loud to very soft.?

First, I’ll review the key product in the system which is RDL’s HR-MCP2 Dual Microphone Compressor; a game-changer in the world of audio technology! This dual-channel microphone compressor is designed to produce consistent audio output levels with wide variations of mic input levels (up to 25 dB), as well as protect against distortion and clipping from signal overloads.? The HR-MCP2’s gain reduction is nearly instantaneous for both expected high audio peaks as well as severe input overloads.? These variations are typically caused by variety of presenter’s speaking styles, coughs, sneezes, and the occasional mic drop.?

This compressor is equally perfect for on-air broadcast, voice-over and recording studios, as well as public address systems, meeting rooms, public venues, and every commercial sound system.

Important point: the HR-MCP2 is designed to maintain average output levels without compromising the sonic integrity of dynamic sources. ?It offers exceptional input headroom, wide flat frequency response, and extremely low noise, with very high common-mode signal rejection. It can be operated as a stereo mic compressor or preamplifier, or as two separate mono compressors/preamplifiers.?

Each channel comes with a front-panel FILTER switch for low-cut filtering and an INPUT PAD switch which allows the operator to attenuate the input signal by 15 dB prior to the input stage. ?The GAIN control provides continuous adjustment to set the correct gain for normal microphone levels.? And with its unique circuit design, it offers studio-quality low-noise performance at any gain setting.

Each channel provides two balanced input and output formats: XLR and detachable terminal block, and selectable 48 Vdc phantom to support dynamic and condenser microphones. The HR-MCP2 is housed in a durable half-rack-width shielded metal enclosure, suitable for free-standing use or for mounting in an optional RDL rack adapter.

In this House of Worship system example, one channel of the rack-mounted HR-MCP2 Dual Microphone Compressor is connected in-line between each church microphone and the house mixer. The HR-MCP2 automatically adjusts the volume for best intelligibility for a wide range of presenters’ speaking styles, from soft-spoken to boisterous.

Phantom voltage (IEC Standard 48 Volt) may be provided by the HR-MCP2 to power any condenser microphone. The HR-MCP2 provides transparent audio level adjustment and compression over a 25 dB range. It ensures freedom from clipping and overload distortion, providing consistent audio levels throughout a presentation, and from one presenter to the next.

This single HR-MCP2 provides automatic gain reduction for two separate microphones, one at the pulpit/lectern and one wireless (switched to mic-level output). Front-panel LED metering strings simplify proper gain adjustment. Multiple HR-MCP2 Dual Microphone Compressors can be rack mounted to control all the microphones in the church for maximum system intelligibility.

For superior audio clarity, user adjustments, reliability, compactness, and unsurpassed versatility and performance, the HR-MCP2 is the ideal choice for improving audio intelligibility in any system.?
