Architecture and Engineering Specifications
The control centre shall be designed for digital audio mixing applications and be optimised for use in live performance. It shall feature 64 simultaneous input channels with 8 integrated microphone preamplifier inputs and 27 time-aligned and phase-coherent output mix buses and operate at 96 kHz sampling rate.
The control centre shall support 100 Mbit/s Ethernet frame-based digital audio networking with a total network channel count capability of 156 inputs and 164 outputs at 96 kHz sampling rate.
The 100 Megabit Ethernet frame-based digital audio network shall off er N+1 cable redundancy and be compliant with the Audio Engineering Society AES50-2011 standard.
The control centre shall provide a combination of up to 28 assignable digital audio emulations of industry standard one-third octave proportional-Q response graphic equalisers and 6 multi-channel digital signal processing effects engines. There shall be automatic latency management of all internal routing, external analogue insert and digital signal processing delays. This latency management system shall synchronise audio samples when summing to mix buses to ensure phase alignment of the summed signals.
The control centre shall provide a user navigation system including 8 variable control association (VCA) groups and 6 population (POP) groups.
The control centre shall have 20 motorised 100 mm faders with a rated life time of up to one million cycles and one daylight-viewable 15" full colour display screen. It shall include software interpolation of physical control elements and associated display feedback to eliminate digital quantisation artefacts.
The control centre shall have the provision for the optional wireless control using an Apple iPad, with a bespoke software application available as a free download from the Apple App Store.
The control centre shall include two auto-ranging universal switch-mode power supplies with dual redundancy for use on a worldwide basis. The power supply modules shall be externally removable.
The control centre shall be 882 mm wide x 730.3 mm deep x 274.9 mm high (34.7" x 28.7" x 10.8"), with nominal weight 37 kg (81.4 lbs). The control centre shall be installed on a flat horizontal surface capable of safely supporting its weight. Input, output, and power connections shall be made at the rear panel of the control centre. Installers shall allow adequate space at the rear for connection and disconnection of input, output, and power connections. The power requirements shall be 100 to 240 VAC, 50 to 60 Hz.
The control centre shall be supplied in a touring package including a road case constructed from marine grade plywood with aluminium extrusions, with internal support provided by protective composite density foam. The road case shall be 964 mm wide x 455 mm deep x 1116 mm high (38.0" x 17.9" x 43.9") including castor wheels and the gross weight of the control centre in the road case shall be 120.2 kg (264.4 lbs).
The control centre shall be the MIDAS PRO2C-CC-TP and no other alternative shall be acceptable.
