INTEGRATED AUDIO MANAGEMENT / LOUDSPEAKER PROCESSOR

Installation audio processing becomes a whole lot easier with the introduction of the DC1048. Working in conjunction with both iCore and AudioCore, it’s easy to program the unit the way you want, and then unplug the computer, safe in the knowledge that settings can’t be changed, and even if they are, setting up timed presets ensures they’ll be back as they should be by the next morning! Units may be networked via RS485 and are compatible with the wireless Walkabout system.
The digital processor shall provide 4 inputs,and 8 outputs. It shall provide four into eight channels of matrix mixing, with each input channel including 8 bands of parametric EQ, all with adjustable response types. Each output channel shall provide high and low pass filters, 9 bands of parametric EQ (with adjustable response types), a program limiter ad a clip limiter.
There shall be up to 650mS of delay available on each output, in 300nS increments. Any output mya be fed from a mix of any of the four inputs with variable matrix mxing for the relative elevsl fo the four inputs.
Headroom metering shall be available for inputs and outputs.. Parameter information shall be shown on an LCD display. Only basic set-up of interface options and preset recalls shall be available from the front panel, and this may be locked out either completely or allowing preset recalls only. A additional security lockout facility shall be provided to limit remote access, augmented by full remote control from a PC via USB, or RS485.
The unit shall offer front panel recall of up to 20 memories, up to 16 of which are also available via closed contact GPI recall interface. A real time clock and calendar will also allow for automatic recalls on either a one-shot or repeated weekly basis.
The audio processing shall meet or exceed the following specifications:- Frequency Response +-0.5dB 20Hz - 20kHz (-3db @ 32kHz). Dynamic Range > 112dB 20Hz - 20kHz unw.
Inputs and outputs shall be via “Phoenix” connectors and be electronically balanced. GPI connections shall be via “Phoenix” mini-connector strip. The digital audio processor shall be a 1U, 19" rack mount device capable of operating from a 60V AC - 240V AC 50/60Hz supply. The digital audio processor shall be the XTA Electronics model DC1048.
