The new NHB32-C Network Hub and Bridge is equipped with four AES/EBU terminals for connectivity between digital audio devices via the Cobranet, whilst the ACU16-C Amplifier Control Unit operates as an output device that can be used in combination with Yamaha¹s new PC9500N or PC4800N power amplifiers. The ACU16-C allows both control and monitoring of the PC-N series amplifiers and features high quality DA converters delivering high quality analog output to the PC-N series.
A maximum of 8 NHB32-C and 16 ACU16-C devices can be connected to a single network. Both units also allow the relay of control data systems (Amp Control, COM or MIDI) between other units on the network, and run lengths of up to 100m are possible using 100 Base- TX Cat 5 cable and up to 2km using fibre optic cable. Audio patching, word clock settings, monitoring and control of amplifiers is made possible through the packaged software.
The ACU16-C amplifier control unit offers a Cobranet interface with on board 16-channel high quality 24-bit DA converters, allowing reception of up to 16 channels of digital audio. Seamless Cobranet operation is guaranteed, say Yamaha, thanks to the incorporation of both Primary and Secondary terminals ensuring that in the unlikely event of a problem with one line the backup line takes over. Euroblock terminals provide quick and easy connection to the amplifiers.
Bundled software allows control and management of a maximum of 32 power amplifiers whilst the RS-485 Network terminal allows control and monitoring of up to 32 network compatible PC9500N or PC4800N power amplifiers. Single location network control over audio patching, settings is possible via a Windows equipped PC.
