AKG launches DMM 4/2/2 digital microphone mixer

At InfoComm 2009 in Orlando, Florida, AKG announced the release of the DMM 4/2/2 automatic microphone mixer. The DMM 4/2/2 is a processor controlled digital automatic mixing algorithm with four balanced universal (microphone/line) inputs and two stereo AUX inputs providing an intelligent mixing algorithm with noise sensitive threshold. The DMM 4/2/2 was also exhibited at IBC 2009 in Amsterdam and at PLASA 2009 in London. The DMM 4/2/2 mixing algorithm automatically allocates gain among the system microphones (NOM attenuation) with a special noise detect function and the “Noise Sensitive Threshold” algorithm (NST) that eliminates an accidental switching of the input channels. The mixing algorithm features a “Last Mic On” function as well as a “Best Mic On” mode and the control concept allows users to access all microphone functions via a single rotary switch for intuitive operation. The DMM 4/2/2 incorporates a dbx compressor/limiter, which provides clear and pristine sound quality to an array of applications. Each channel has switchable gain (Mic/Line, Mic-Lo/Mic-Hi) and switchable phantom power. Every input is equipped with an incremental level control, including LED level and peak hold display. The auto-mixing and ducking function can be enabled/disabled for each microphone and AUX channel individually providing an expansive amount of flexibility. The DMM 4/2/2 has an expansion connector to cascade multiple mixers in a bigger system and a control I/O is located on the rear panel, providing logic in and outputs to control external devices. The DMM 4/2/2 comes in a rugged 19” housing with an integrated power supply unit, one recording output via two RCA connectors and one master XLR output. The mixer can also be remotely controlled via logic in/outs with a Sub-D connector. Each input incorporates a volume control, high frequency shelving filter, a low frequency shelving filter and a switchable bass cut filter. The main output is equipped with an adjustable limiter as well as a master level control and all functions are controlled from the incremental controls on the front panel. The mixer also provides a software locking function to avoid unwanted operation.
