BLU link In/Out
The Digital Audio Bus is a high bandwidth, fault-tolerant bus of 256 channels at
48kHz and 128 channels at 96kHz. Devices are connected, using Cat 5e or Cat 6
cable, in a ring from the OUT connector of one device to the IN connector of the
adjacent device. The distance between devices in the ring can be up to 100m on
Cat 5e or Cat 6 or up to 10km on single mode fiber using the MC-1 fiber media
converter. The ring topology allows any single cable fault without loss of channels.
All devices within a given Digital Audio Bus ring must be configured for the same
sample rate. The sample rate of the PDP-BOB output expander is automatically
configured based on remotely configured devices within the Digital Audio Bus
ring.
Channel Select
The PDP-BOB output channels are easily configured by six DIP switches located
on the rear of the device, which select a range of 8 consecutive channels from
the Digital Audio Bus. Output channel assignments are configured by DIP switch
selection only.
Analog Output 1-8
The 8 analog line level outputs utilize the terminal block connectors.
