Soundweb™ London
BLU-50
OVERVIEW:
The Soundweb London BLU-50 offers a a fixed configuration of four inputs and four outputs, configurable signal
processing, logic processing and a high bandwidth, fault tolerant digital audio bus.
The BLU-50 has open architecture which is fully configurable through HiQnet™ London Architect. A rich palette of
processing and logic objects and a “drag and drop” method of configuration provide a simple and familiar design
environment.
This processor features a low latency, fault tolerant digital audio bus of 48 channels which uses standard Category 5e
cabling giving a distance of 100m between compatible devices. Fiber media converters can be used to increase the
distance between devices to over 40km.
The BLU-50 is compatible with the entire Soundweb London family and its 48 channel digital audio bus represents
channels 1-48 of the larger 256 channel digital audio bus when integrated with the BLU-806, BLU-805, BLU-800,
BLU-326, BLU-325, BLU-320, BLU-160, BLU-120, BLU-102, BLU-101, BLU-100, BLU-BIB and BLU-BOB devices.
Analog Inputs provide software configurable gain in 6dB steps up to +48dB per channel and software selectable Phantom
Power per channel.
Phantom Power, Signal Present and Clip information per channel is easily accessible, without the requirement for a PC,
from clear front panel LED indication. A bi-directional locate function allows devices to be identified both from and
within HiQnet London Architect.
12 Control Inputs and 6 Logic Outputs and an RS-232 port allow the BLU-50 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 London Architect.
The chassis is a half rack wide and can be rack mounted using the BSS Audio 1U Rack-Mount Kit. It can also be
undertable mounted or wall mounted using the included mounting brackets.
The device can be powered with the included 12VDC power supply, but can accept 12-48VDC via a terminal block
connector. The BLU-50 can also be powered with PoE+ via the Ethernet port, allowing the device to be powered,
configured, controlled and monitored using a single Cat 5e cable.
The BLU-50 and the other members of the Soundweb London family provide the building blocks of the perfectly tailored
system solution.
