The A 5400 digital audio processor is a comprehensive system which integrates pre-amplifier, compressor limiter, equaliser, as well as matrixing and delay functions into one unit. Useful features like automatic gain control, feedback killers, auto microphone mixers and crossovers are also part of the A 5400 impressive components library. A unique digital signal processor manages up to 8 microphones (VOX or contact activation) with different priority levels.
Internal processing of audio signals can be fully programmed to suit the clients application. Installers can select the audio processing features they wish to apply to the various inputs and outputs with the provided PC software. Once the configuration process is complete, it can be uploaded to the A 5400. All configurations can be backed up onto PC and loaded into the A 5400 when required.
Each front panel control can be associated to any of the variable audio processing functions of the A 5400, including: input level, output level, source selection, routing, preset changes. For remote configuration changes A 5412 wallplates may be installed in each zone and connected to the A 5400 via its analogue control inputs. Wallplates allow source selection and volume control adjustments. The A 5400 can also be controlled via an external system such as Crestron AMXor by a PC and supplied software.
The A 5400 has 8 universal balanced audio inputs and 8 balanced audio outputs. It is also fitted with 8 TTL logic inputs and outputs. Each of the hardware inputs or outputs can be associated to virtually any software audio processing feature the system designer requires.
The A 5400 presents the end user with state-of-the-art technology while remaining user-friendly.
All of these functions make the A 5400 well suited to audio signal processing in places of worship, auditoriums, function centres, clubs, halls, pubs and shopping centres etc.
