    Formerly known as BLU-326

    The Soundweb London BLU-326DA offers configurable I/O, Dante / AES67 audio, and a high bandwidth, fault tolerant digital audio bus.

    The BLU-326DA is configurable through HiQnet™ Audio Architect. A rich palette of logic objects and a “drag and drop” method of configuration provide a simple and familiar design environment.

    This processor features Dante / AES67 audio with primary and secondary ports for fault tolerance, with control through a separate Ethernet port. As well, the processor includes support for Dante 4.0 firmware for integration with Dante Domain Manager.

    The BLU-326DA also features a low latency, fault tolerant digital audio bus of 256 channels which uses standard Category 5e cabling giving a distance of 100m between compatible devices. Fiber optic media converters can be used to increase the distance between devices to over 40 km.

    Four card slots which accommodate analog inputs, analog outputs, digital inputs and digital outputs in banks of four facilitate many different device I/O configurations.

    Analog Input Cards provide software configurable gain in 6 dB steps up to +48 dB per channel and software selectable Phantom Power per channel. Digital Input Cards and Digital Output Cards process AES/EBU and/or S/PDIF audio and offer a variety of clocking and syncing options. (Further information about the I/O cards can be found on dedicated datasheets)

    Phantom Power, Sync, Signal Present and Clip information per channel is easily accessible, without the requirement for a PC, from clear front panel LED indication. Device-specific information such as Device Name, Device Type, Firmware Version Number, Time, IP Address and Subnet Mask is available from the front panel display. A bi-directional locate function allows devices to be identified both from and within HiQnet Audio Architect.

    12 Control Inputs and 6 Logic Outputs allow the BLU-326DA to be integrated with GPIO compatible devices.

    The Soundweb London Interface Kit, comprehensive documentation which details how Soundweb London systems can be integrated with third party control systems, is included within the installation of HiQnet Audio Architect.

    The BLU-326DA and the other members of the Soundweb London family provide the building blocks of the perfectly tailored system solution.
