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.
4. The delivery status
The scope of delivery includes: 1x DA 230, 1x PowerCon-mains cable, 1x rack-mounting
set, 4x rubber base and user manual

the main menu are pre-set:
- „Preset 1“ is loaded
-
Sig. LED threshold is adjusted to -50 dB
-
User LED threshold is adjusted to 0 dB (0 dB = deactivated)
-
output levels are shown on the LCD display
-
input A is switched to analogue
