The DQRack is the optimum amplification and control package for any EM Acoustics system, intended to offer a standardised solution primarily for mobile and touring applications. The combination of three Dante-enabled DQ20D amplifiers along with a dedicated signal I/O and output/mains power I/O package provides vital flexibility and effortless expandability.
  • Dedicated output and mains power distribution
  • 32A 3-phase universal power supplies
  • Concealed integrated flying system
  • Shock-mounted frame for all electronics contained within rugged plywood construction

The DQRack is a flyable touring rack comprising 12 channels of premium Class-D amplification within the 10U shock-mounted frame. Built for a life on the road, the DQRack is the optimum solution for touring with unmatched versatility and for a wide variety of different applications. The DQRack contains three Dante-enabled DQ20D amplifiers, a dedicated signal and data I/O unit and a dedicated output and mains power distribution unit to give maximum flexibility in use. All inputs and available from the front panel, whereas outputs and mains power are presented on the rear to keep cabling neat and efficient.

The SigIO input and data distribution unit provides four analog inputs – linked to all amplifiers – as well as the individual AES input and buffered AES output for each amplifier. It also contains a managed Cisco network switch to generate separate VLANs for Dante Primary, Secondary and Control networks, with trunk ports to allow linking of racks with the minimum of cable, and optional connectors for optical fibre. Status LED’s for the network switch are presented on the front panel for easy identification.

The PowerIO unit is presented on the rear of the DQRack and offers all connections for mains power and loudspeaker output distribution. Outputs are provided in two formats – two 19-pole connectors handle 6 amplifier channels each (identified by the clear graphical legend by each connector) and are the optimum choices for large array applications. For increased flexibility, each amplifier also has its own speakON NL8 connector that carries the four channels of each specific amplifier. Mains input to the DQRack is handled by a 32A 3-phase connector on a trailing cable, and a 32A 3-phase output is provided for linking racks. Additionally, two local power outlets are also provided – an internal Neutrik powerCON connector supplies power to the SigIO unit, and an external 20A powerCON connector is provided for local power needs – this output is isolated on its own MCB.

The mechanical package of the DQRack is another area where no compromises have been made. All components are housed within a shock-mounted frame, ensuring maximum protection against damage in transit. The external casing is manufactured from premium Birch plywood, coated in the same 3-step polyurethane finish as our loudspeaker products making the DQRack not just aesthetically consistent but inherently rugged and reliable. Sliding rack doors minimise wasted space, and the external dimensions are optimised for efficient truck pack. Concealed within the sides of the DQRack is a simple and efficient flying system – which allows up to three DQRack units to be safely suspended from the optional FG-DQRack flying grid. For flying or stacking, the wheelboard is easily removable from the base of the DQRack to allow the flying hardware to engage between racks. The flying system doubles as a means of safely locking stacked racks together – although recesses for castors to sit in are also provided for temporary stacking.

The DQRack is ideal for any EM Acoustics touring loudspeaker system but has particular merit with HALO-A and HALO-B line array systems.
