Detailed Description DM32
DM32 is the processing MixRack in an Allen & Heath dLive digital mixing system. Its 96 kHz XCVI FPGA engine supports 128 input channels and 64 configurable mix buses, independently of the amount of local analog I/O. This model provides 32 microphone/line inputs and 16 line outputs.
The mix engine includes full input and output processing, DEEP embedded processing, sixteen RackExtra FX engines and dedicated stereo returns. Flexible buses can serve groups, auxiliaries, FX sends, matrices and mains. Automatic mic mixing, DCAs, a signal generator, RTA and spectrogram support a broad range of live and installed workflows.
3 optional 128-channel I/O slots provide connections for compatible audio-network formats. Redundant gigaACE and DX links support resilient system connections. A dLive surface or compatible software provides control. RackUltra FX requires the optional upgrade; it is not included in the original base MixRack.
