The 2-channel amplifier DA 230 is equipped with comprehensive DSP features like matrix router, 6 fully parametric equalizers two crossover networks, delay and dynamic processor per channel. Factory and user presets may of cause be stored inside the unit, an SD-card reader is implemented and can be used to easily transfer preset and system information to other units. All parameters as well as user navigation can be managed using a simple 5-key navigation pad together with 4 rotary encoders. The sophisticated user interface is completed by a graphic LCD display and 4 RGB LEDs informing about relevant operation parameters and state of the single channels. On the inputs side are two analogue or one digital XLR connectors which can also be used mixed. Link sockets, either carrying the signal applied to the inputs can be routed as >processed< digital outputs. The outside power connection was realised using a self-locking Neutrik PowerCon connector, two Neutrik Speakon sockets ensure the connection to the speaker systems. The designers also implemented a module slot for future updates, i.e. connections to audio / control networks, standard- fitted with module RSNC equipped with a RS232 connector and a 'normally closed' contact feature. Another important feature is the PFC controlled, audio-optimized wide-range switched- mode power supply of the last generation. A top feature if the absolutely quite "low-noise" fan. An extensive set of protective circuits short circuit, DC on output, impedance undercut and digital monitoring functions like log book with using and power hour meter are included 'rounding off' the professional features of this equipment. Its wide-range application scope lasts from monitor — over the use in passive components to the realization of multi-channel systems within sound installations. The DA 230 is mainly intended for the amplification of more powerful reinforcement components. By the optional available PC software Preset-Editor you can create own presets on your computer. This KME preset files can be saved on an SD card and later transfered to both digital amplifiers DA 428 and DA 230. From now on Firmeware-Updates can also be transfered by an SD-card on DA 428 and DA 230.
