Allen & Heath AH-DLIVE-DM64 dLive S Class MixRack 64x32 I/O, 128 x 64 FPGA, 3 option I/O, ME-1 port, Dual DX Expander Link, Hot Swap PSU

 The MixRack is the heart of any Allen & Heath dLive system. It houses the XCVI processing core complete with audio I/O, control and audio networking ports. It is typically connected to a dLive Surface, but can also be controlled at the same time as or even without a Surface using a laptop or iPad, Allen & Heath IP remotes or third party controllers via TCP/IP.

There are 3 sizes of dLive MixRack available, with this model; the DM64, being a 64-input, 32-output version. All feature the same mix engine and differ only in the number of analog I/O. All models can work with the full 128 channels by adding DX expanders or patching digital sources.

XCVI Core - The power of dLive emanates from the XCVI Core – using next generation FPGA technology - with 36 parallel virtual processing cores generating enough power for 160×64 channels of processing at 96kHz sampling rate. Six parallel mixing engines within the Core calculate over 10,000 cross points per sample, while the FPGA router has capacity for 3,000 x 3,000 audio paths. The massive power of XCVI (25 billion operations per second) allows dLive to deliver 128 full processing inputs and 16 stereo FX returns, a configurable 64 bus architecture, variable bit depth for ultimate precision and noise performance, a virtually infinite mix headroom thanks to a 96-bit accumulator, and class leading latency at an ultra-low 0.6ms.

Deep Processing - DEEP processing architecture embeds class-leading compressors and processing emulations directly within dLive’s input and mix channels. An array of bespoke algorithms including Graphic EQs and Compressor models can be inserted on the fly without burning FX slots and without the setup, latency and license hassles associated with external plug-ins – right there, where you need them, whenever you need them. The compressor models capture the audio nuances and non-linear ballistics of industry classics, ranging from a Slow-Opto model, various RMS detection and soft knee circuits, through to super-fast peak and RMS-based compression/limiting devices.
