2.2. Audio engine description.AEQ CAPITOL is an ultra-compact digital audio mixer for Radio and Television consisting in acontrol surface and an associated audio engine, specially designed for ON AIR broadcastcontrol, highly adaptable to different operational situations. The following chapters will describeAEQ CAPITOL audio engine.The AEQ CAPITOL audio engine or core unit consists in a 2RU chassis (89mm or 3 1/2”height), designed to be installed in standardizedd 19” (482mm) racks. As with the rest of AEQCAPITOL, the audio engine size has been minimized without leaving any feature out, its depthbeing only 330mm.AEQ CAPITOL audio engine does not have any fans or moving mechanical parts for cooling.Therefore its operation is totally silent and can thus be installed inside radio studios. The unitcooling relies on convection air flow. For this reason it is strongly recommended to leave somespace above and below the equipment. It also takes advantage of the good thermal conductivityproperties of the metal elements of the chassis to channel the residual heat to the front panel,where it is dissipated.Ease of installation and set up been a priority during the design of CAPITOL, so audio input andoutput, control monitoring and auxiliary signals configurations of the mixing console are fixedand defined from Factory:• 4 balanced microphone / line level inputs.• 12 line level balanced mono analog inputs.• 4 AES/S/PDIF digital stereo inputs.• 8 line level balanced mono analog outputs.• 4 AES/S/PDIF digital stereo outputs.• 2 stereo input/output USB computer connections.• Control and Studio headphone outputs.• Stereo unbalanced CUE output with line level.• Stereo balanced analog outputs with line level for control and Studio monitors.In order to connect external cough-cuts, remote control external devices, ON AIR lights, etc,AEQ CAPITOL features 8 general purpose digital inputs (GPI), 8 outputs (GPO) and another 4relay-switched outputs. The system configuration and remote control is carried out through anIP based Ethernet connection.AEQ CAPITOL has an optional bi-directional MADI interface (optional and subject to a specificuser license) that can carry up to 64 digital inputs and outputs as well as two optional digitaltelephone hybrids.For ease of wiring and avoid errors in the installation process, audio and data cables with DB15male connectors required to connect the console can be optionally supplied. In any event, it isnecessary to use shielded and balanced audio cables and that the connection to the DBconnectors are made by technically qualified personnel and properly verified before connectingthe equipment. Further, optional power supply and wiring for control and studio signalling andGPIO can be supplied.AEQ CAPITOLUltra-compact digital audio mixer19
