Analog
The BD600+ provides XLR differential audio connections
for two input channels and two output channels. When by-
passed, the audio pins of each input channel are connected
to the audio pins of each output channel using a relay. The
unit is automatically bypassed when power is disconnected
or turned off. Note that neither pin 2 nor pin 3 should be
left unconnected or you will get more noise and distortion
than signal. Be aware that the ¼” jack inputs are not supported by the bypass function and should not
normally be used.
Analog Outputs
These male XLR connectors provide a differential bal-
anced audio output with a maximum level of +24dBu and
a nominal level of -4dBu. Pin 1 is grounded to the case of
the external XLR connector. Pin 2 is +phase and pin 3 is –
phase.
Each connection may also be used as an unbalanced line.
The BD600+'s XLR analog audio output connectors are
male. Pin 1 is grounded. Connect pin 2 to your center con-
ductor and connect pin 3 to pin 1. Both pins 2 and 3 must be connected at all times.
Analog Inputs
These female XLR connectors provide differential bal-
anced audio input. The input level has a maximum value
of +24dBu and nominal level of -4dBu. Pin 1 is grounded.
Pin 2 is +phase and pin 3 is –phase.
Although the inputs of the BD600+ are balanced, you can
still use them with an unbalanced line. The BD600+ XLR
analog audio input connectors are female. Pin 1 and pin 3
would be grounded, while pin 2 is your audio signal. Both
pins 2 and 3 must be connected at all times.
In the case of an XLR to XLR balanced line (differential)
cable the shield should be left disconnected on one end
(usually on the end connected to an instrument output).
This helps to prevent ground loops. The use of balanced
connections is recommended.
Digital
These cables are differential with a shielded twisted pair.
For short distances microphone cables can be used, but
for longer distances and permanent installation a digital grade twisted pair cable is recommended.
AES/EBU input, XLR
The BD600+'s connector is female. Pin 1 is shield, 2 and 3 are differential.
