3 Connections of the BB35
extremely simple.Only two connections need to be made; mains power and audio signal.
A Stage Control connection is not neccesary for the functioning of the Blue box
Because all the components of a Blue Box are contained in a single cabinet, connection is

Mains Power Connection
voltage is configured at the factory according to standard used in the country of destination. The
The BB35 is internally selectable for 110-120/220-240V 50/60Hz mains voltage. The mains
exact voltages are stated at the frontpanel of the PMS6000. Switching between mains voltages
needs to done by selecting a jumper between position X1 and X3 on PCB BB3501.
Connecting to the wrong voltage is dangerous and may damage the PMS6000. Always ensure
that you use a correctly grounded power supply.
It is advisable to connect each unit seperately to the nearest main power supply socket.
The maximum advice for linked Blue Boxes using the AC out link on a 16A mains supply is 2
units.

Audio Connections
The XLR connectors (analog audio, AES/EBU in and link) of the BB35 are wired as follows:
Pin 1
= shield
Pin 2
= normal phase ( or “hot”)
Pin 3
= inverted phase (signal- or “cold”)
Always use high quality XLR connectors and shielded signal cables. Using the signal link
connectors, up to 30 BB35s can be linked without a problem. If more than 30 BB35s need to
be interconnected, a separate signal driver should be used.
The input stages are electronically balanced. To make optimum use of the balanced input stages
even in unbalanced situations, use balanced signal cables and connect pin 3 to pin 1 at the
output of the preceding equipment. If this is not possible, connect pin 3 to pin 1 at the input of
the BB35.

The digital input of the BB35 offers two input channels on one electronically balanced XLR-
connector and will accept AES/EBU and S/PDIF input signals of 16 to 24 bit 44.1, 48, 88.2 or
96kHz. Use the control panel or Stage Control to select reproducing left or right channel.
