BMC-1 CONTROLLER (PZA)
The M&K Sound BMC-1 is a balanced, line-level studio bass management controller designed for use with M&K Sounds' line of professional studio monitors and high-end home theater installations. Although the BMC-1 was primarily designed for monitoring 5.1 audio, its flexible architecture allows it to be used for monitoring mono, stereo, Dolby Surround, Dolby Digital, DTS, and other formats.
The BMC-1 combines several necessary functions into a 1RU 19-unit rack-mount package. Along with bass management and LFE channel control, it also provides individual channel adjustment capability to properly calibrate your entire monitoring system.
The controller consists of a series of five high-pass filters (one for each channel L, C, R, LS and RS) that route high-frequency information (above 80 Hz) to the amplifier and speaker of their appropriate channels. Each channel is also routed through a corresponding 80Hz low-pass filter. This low-frequency information is then sent to a summing amplifier, which in turn sends this low-frequency information, along with the LFE channel, to two subwoofer outputs.
This is done for two reasons. First, small speakers may not be able to properly reproduce information below 80 Hz. This information is then summed up and routed from the individual channels to a speaker that can reproduce this low-frequency information clearly and powerfully: a subwoofer. With the introduction of digital audio, it has become necessary for speaker systems to accurately reproduce audio with a bandwidth of 20 Hz to 20 kHz with wide dynamics. A satellite/subwoofer system is the best way to achieve this.
Second, today's home theater receivers use bass management based on Dolby requirements. For the work done in the studio to translate correctly, the mixer must hear your mix exactly as it will ultimately be played back. The BMC-1, in conjunction with a properly set up and calibrated M&K Sound monitoring system, allows the mixer to hear their work more accurately than would otherwise be possible.
