Audio Mixing System

The PRO6 standard package comprises of:-

• 35 Bus Console (plus 6 solo for 5.1)
• 64 main inputs (or 56 input and 8 aux return)
• 56 XLR mic/line inputs
• 16 XLR line outputs
• 8 Jack line inputs
• 8 Jack line outputs
• 4 AES/EBU inputs
• 4 AES/EBU outputs
• 1 Control Centre in flight case
• 1 main rack case housing DSP and I/O
• 4 interconnecting (N=1) rack Cat-5E copper cables
• 2 interconnecting (dual redundant) gigabit Hyper-MAC 100m Cat-5E copper cables

The system shall comprise of robust steel, 19” rack mountable, modular units that can be interconnected via N+1 or dual redundant cables to provide a scalable audio signal network with signal processing and mixing capability.

A central control surface shall be provided consisting of multiple modules housed in a robust steel chassis that can be located well away from the rest of the system and connected by dual redundant multi-channel digital fibre or copper “snake”. The entire system shall be fault tolerant such that no single interconnecting cable fault can stop the system operating to its full capacity. All external interfacing, internal processing and system controls shall be modular such that loss of power to any single module only affects that module allowing the remainder of the system to operate normally. The operational status of all the system modules and interconnections shall be continuously monitored and reported at the control surface.

The system shall be configurable to meet all of its I/O, processing and control surface requirements within an easily portable, two flight case, solution that is fast to set up and only requires the interconnection of one digital audio cable (two for dual redundancy) and power to make it operational.

The system shall be expandable and capable of sourcing inputs and driving outputs from multiple locations so that for example all inputs can source their signal from a hard disk recorder for sound checking but switch over to microphone feeds for the main live show event.

The system shall be capable of mixing 56 primary input channels and 8 auxiliary input channels simultaneously to 35 main bus output channels, with equalisation every channel and dynamic processing on all outputs and primary input channels. 8 effects processors shall be included that can be inserted into any channel path with the ability to add additional external insert points to any of the channels, as desired.
