3. The completely digital 2-channel DSP-amplifier 

 

The DA 230 is a completely digital 2-channel amplifier with 1500 W @ 4 ohm output 
power on each channel. This compact, light- weight 19"-2U device is equipped with 
comprehensive DSP features like matrix router, 6 fully parametric equalizers, two 
crossover networks, delay and dynamic processor per channel. 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 LED`s informing about relevant operation parameters and state of the 
single channels.  
Factory and user presets may of course 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. An preset editor software and various firmware add- ons are available as well.  
On the inputs side are 2 analogue connections as well as 1 digital port accepting 
AES/EBU and SPDIF formats of 16 to 24 bit and 32 to 192 kHz  sampling  frequency.              
2 link sockets, one of them carries the signal applied to the inputs can be routed as 
“processed” digital output carrying AES/EBU of 24 bit / 48 kHz. 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. Global remote control is guaranteed using future 
firmware upgrade modules, but even the standard version contains simple remote 
features. Another important feature is the PFC controlled, audio-optimised wide-range 
switched- mode power supply of the last generation.  
The outside power connection was realised using a self- locking Neutrik PowerCon 
connector, 2 Neutrik Speakon sockets (channel A is wired ´bi-amp´) ensure the 
connection to the speaker systems. An extensive set of protective circuits and digital 
monitoring components is included ´´rounding off´´ the professional features of this 
equipment. The DA 230 is usable for intelligent bass management operation to system 
operation of passive PA components or realisation of professional multi- channel systems 
within sound installations.
