At InfoComm, 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 a unique and very intelligent mixing algorithm with noise sensitive threshold.
The DMM 4/2/2 mixing algorithm automatically allocates gain among the system microphones (NOM attenuation) with a special noise detect function and the âNoise Sensitive Thresholdâ? algorithm (NST) that eliminates an accidental switching of the input channels.
The mixing algorithm features a âLast Mic Onâ? function as well as a âBest Mic Onâ? mode and the revolutionary control concept allows users to access all microphone functions via a single rotary switch for a very intuitive operation.
To compensate for level differences or any other obstacle, 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 and 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 19â? housing with an integrated power supply unit, one recording output via 2 chinch 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.
