The Allen & Heath CDM32 dLive MixRack audio mixer 32×16 I/O is a 5U rack-mountable device that can operate independently, with or without a control surface. It can handle 128 input channels, 64 mix busses and over 400 soft-patchable system inputs and outputs, all independently assigned. There are 16 rack-mounted stereo FX engines with dedicated stereo returns, and 24 DCAs. The rack unit contains the mixing engine. This mixing engine operates at a sampling rate of 96 kHz and uses FPGA technology for digital signal processing. The system latency from analogue input to output must not exceed 0.7ms. The Allen & Heath CDM32 for dLive systems provides 32 high-quality XLR inputs capable of handling microphone or line signals and will have a remote-controlled analogue gain adjustable in 1 dB steps, a 20 dB PAD and phantom power. All input channels are configurable mono/stereo and will have access to any of the unit’s hardware inputs or remote inputs via expansion options. Mixing buses are configurable as any combination of mono/stereo aux sends, groups, mains, FX sends or matrixes. All output channels are routed to any of the unit’s 16 XLR line outputs or to a remote output via expansion options. All input channels contain the following processing: Trim, Polarity, High Pass Filter, Low Pass Filter, two insert points, Gate, Parametric EQ, Compressor and Delay. All output channels of the mix must contain the following processing: External Input, Trim, Polarity, Insert, Parametric EQ, Graphic EQ, Compressor, Delay. Parametric, Graphic EQ, Compressor, Delay. Channel processing provides high-quality emulations of classic compressors and GEQs. These emulations can be inserted on any channel, without using the internal FX and without the need for external plug-ins or licences. The Allen & Heath CDM32 mixer also provides automatic mic mixing (AMM) of up to 64 mic sources in 1 or 2 or 4 zones. There is also a single 128-channel I/O port for an optional digital interface module. Optional interface modules include: MADI, EtherSound, Dante, Waves SoundGrid and ACE. The unit is equipped with a fixed power supply accepting AC mains voltages of 100~240V, 50/60 Hz, 175W max via a 3-pin grounded IEC male connector. The Allen & Heath audio mixer for dLive systems allows 500 scenes to be saved.
