BLU-SV8T Source Selector/Volume Control
The BLU-SV8T is a
source selector/volume
control for BSS Audio
London Series Digital
Signal Processors. It is
built on a dual gang
panel for mounting in a
dual gang electrical box.
The front side of the
control has 8 lighted
momentary pushbutton
switches for selecting
audio, and a pot for
the audio signal. On the backside of the control is a single RJ-45 Cat5e
jack for connecting the BLU-SV8 to the DSP via the BLU-CIF or BLUCIF2 SV
orts. The BLU-SV8T installs in the tech room.

BLU-SV8 Wiring Instructions
IMPORTANT: CAT5e wiring for the RJ-45 connector needs to be
crimped to TIA/EIA 568B Standards (see below) on both ends of the cable.
You must crimp and test the wiring with an approved CAT5 568A/B
tester before connecting any cable between the BLU-SV8 and either a
BLU-CIF or BLU-CIF2 Interface unit. Failure to crimp wiring to the
correct standard could possibly lead to component damage.

Note: To complete the BLU-SV8 set-up, a change needs to be made inside
the BSS London Architect software. Be aware that applications may vary in
each installation based on the template being used. If the audio side defines
the source, then navigate to the audio tab and select the DSP being used.
Right click on the desired SV to be converted to an SV8. Select properties,
then change the number of channels to 8 with “allows none” enabled. If the
logic tab defines the source, then change the logic value source from 5 to 9.
Contact BSS Audio if additional support is needed.
