AH-DLIVE-CDM48 - Overview

The Allen & Heath AH-DLIVE-CDM48 dLive MixRack is the heart of the dLive system housing the XCVI processing core. The CDM48 is compatible with any dLive C class or S class Surface. It also can be ran with a laptop, iPad, via the Allen & Heath range of IP controllers, or with third party controllers. The CDM48 features 48 Inputs and 24 outputs, 96K sample rate, the ability to mix 128 input channels and 64 output channels with full processing, built in DEEP processing, Automatic Mic Mixer, and is expandable via the included DX link port and available option card slot.

The power of dLive emanates from the XCVI Core - pioneered by the Allen & Heath R&D team using next generation FPGA technology, with 36 parallel virtual processing cores generating enough power for 160x64 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 96bit accumulator, and class leading latency at an ultra-low 0.7ms.

DEEP Processing
The 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, Compressors and a 64 channel Automatic Mic Mixer (AMM) can be inserted on the fly without burning FX slots and without the setup, latency and license hassles associated with external plug-ins - they're 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.
