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.
Offering full matrix mixing and a pallette of EQ functions to satisfy even the most demanding application, the DC1048 doesn’t compromise your processing, whilst offering a range of installation-friendly features.
24-bit high end converters coupled with a 96k sample rate, ensure a bandwidth in excess of 30kHz and a dynamic range of over 112dB.
XTA’s world class limiters, offer unrivalled transparency, give peace of mind when configuring a system to “set and forget”. Systems that are often driven hard “into the red” and with heavy limiting, more often than not, sound harsh and tiring. Our limitiers are renowned for their smooth controlled behaviour, even when working hard.
Quick access keys make setting up the remote facilities a breeze, with simple easy to remember menus. Preset recalls may also be actioned from the front panel.
The real time clock and calendar in each unit allows for the set-up of fully automated preset recalls, so your system can seamlessly adapt in the background with no need for user intervention.
Display and guide LEDs fade up when the unit is locally accessed, with the display fading up independently when remotely accessed.
With a GPIO interface built in, along with the USB easy access front panel connector, and RS485 networking, it’s easy to get your system configured and then left secure with only remote access via the touch panels (or any other system you choose).
As with all xta products, excellent sound quality is assured through the heritage of the 4 Series processing platform, and the use of high resolution, high sample rate audio converters.
Remote touch sensitive wall panels allow for quick recall of up to four presets (with the facility to program an offset for different banks). These panels can be parallelled up around a venue so any one will trigger a system-wide recall, with messages relaying via RS485. An additional control line allows for an override memory to work with emergency evacuation systems.
