The BVRD2M router has eight electronically balanced inputs and seven electronically balanced outputs. Inputs 1 and 2 are normally reserved for fire microphones and are configurable with an 'all call' processor bypass (one further input can also be configured this way). In the unlikely event of a processor failure the unit also has an 'all call' fail safe emergency message generator. All eight inputs have both independent priority and level settings, allowing for dual mode; emergency and normal page. Any of the inputs or outputs can be aurally monitored through a loudspeaker on the front panel.

All outputs have ten band parametric equalisation with audio delay and inputs have three band parametric plus bass and treble equalisation to provide a high degree of audio processing, enhancing the intelligibility of the system.

The unit has a built-in real time clock for detailed logging of fault history and reporting, both of which can be accessed through the unit's USB2 connection. The BVRD2M has ancillary output/input modules which connect via its CANBUS port, this feature also allows for simple rack wiring. Currently three module options are available; please refer to the BVRD2M CANBUS modules table on the right for further information.

Up to six messages, each of a maximum 57 seconds, with a bandwidth of 18 KHz (CD quality), can be stored in the unit's flash memory, each with independent level, surveillance and timing. These are easily changed via the front panel password protected USB connection; also used to configure the unit. Each unit has nine selectable chimes of up to eight seconds.

A total of 128 BVRD2M units can be networked using fibre, copper or VO I/P to produce a truly sophisticated VA network

DSP control.

Nine chime/preannouncement tones, eight seconds.

Ten band parametric EQ on all outputs with audio delay of up to one second.

1U in height.

Three band parametric plus bass and treble EQ on all inputs, with limiter/compressor.

Six flash stored messages - easy to change via USB2 port, 57 seconds.

Seven outputs, electronically balanced 0dBM audio outputs.

Eight inputs, electronically balanced line -20dB audio inputs.

All call, one off fail safe emergency message generator twenty second EPROM in the event of processor failure.

Ambient noise sensing.

Auto amplifier changeover, one in ten.

CANBUS ports for module connection.

Decentralised networking of up to 128 units.

Front panel encoder for simple programming.

Fully configurable using USB2 connection (Type A to Type B USB2 lead required, not supplied).

Fully monitored, surveillance at either 30Hz or 20KHz; all faults stored within an historic log.

Inputs 1 and 2 can bypass processor.

Inputs 1 to 8 may incorporate two priority levels, one for emergency the other for normal use.

Message synchronisation, even on a decentralised system.

Priority levels to a maximum of fifteen, if two concurrent routes are set at the same priority they will be treated on a first come first served basis. Priorities are changeable.

Real time clock indicates time, date, month and year. Used for date stamping the fault log and may be selected for night volume reduction.

Remote diagnostics via a modem.

Two RS485 ports for networking, microphones, etc.
