Get to the heart of any dLive system with Allen & Heath’s dLive CDM64 C Class MixRack Digital Stagebox. Designed to connect to a dLive control surface (sold separately), the CDM64 can also be controlled using a laptop, iPad, or third-party controllers using TCP/IP. The CDM64 Mixrack Digital Stagebox is ideal for multi-microphone, spoken-word applications of all types and sizes, such as conferences, panel shows, on-stage discussions, live forums, council meetings, and town halls.

Power from the Core

Central to the CDM64’s powerhouse capabilities is its XCVI processing core, which boasts 25 billion operations per second. Complete with audio I/O, control, and audio networking ports, this next-generation processing core uses innovative FPGA technology and combines 36 parallel virtual processing cores that power 160-64 channels at a 96kHz sampling rate. The XCVI core incorporates 6 parallel mixing engines that calculate over 10,000 cross points per sample, while its FPGA router offers capacity for 3,000x3,000 audio paths.

The XCVI provides enough power to the CDM64 stagebox that enables dLive to deliver premium functionality and maximum versatility. These features include:

  • 128 full processing inputs
  • 16 stereo FX returns
  • Configurable 64 bus architecture
  • Variable bit depth
  • 96bit accumulator
  • Ultra-low latency (0.7ms)

Extras and FX

The CDM64 MixRack Digital Stagebox comes with a comprehensive RackExtra FX portfolio. Achieve pristine audio quality while enjoying a versatile range of boutique plugins…all with the convenience and low latency made possible by onboard processing. Using the XCVI Core’s power, Allen & Heath has integrated their library of reverb, delay, and modulator algorithms.

Enable up to 4 zones that allow automatic control of multiple rooms at the same time—all from one interface. For further streamlining of your workload, the CDM64 comes with two modes of Automatic Mic Mixer (AMM) operation:

  • D-Classic uses gain sharing and offers quick and easy set-up
  • Number of Open Microphones (NOM) uses a logic-based automatic mixing algorithm for expanded parameters and increased operator flexibility
