The BD500 provides XLR differential audio con-
nections for two input channels and two output
channels. When bypassed, the audio pins of each
input channel are connected to the audio pins of each
output channel using a four pole relay. The unit is
automatically bypassed when power is disconnected
or turned off.
Analog Outputs
These male XLR connectors provide a differential
balanced audio output with a maximum level of
+4dBm and a nominal level of -20dBm. 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 unbal-
anced line. The BD500's XLR analog audio output
connectors are male. Pin 1 is grounded. Connect pin
2 to your center conductor and leave pin 3 floating.
Analog Inputs
These female XLR connectors provide differential
balanced audio input. The input level has a maxi-
mum value of +4dBm and nominal level of -20dBm,
but an internal attenuator increases the allowable
level to 0dBm for nominal level and +24dBm for
maximum. Pin 1 is grounded. Pin 2 is +phase and
pin 3 is –phase.
Even though the inputs of the BD500 are balanced,
you can still use them with an unbalanced line. The
BD500 XLR analog audio input connectors are fe-
male. Pin 1 and pin 3 are grounded. Pin 2 is your
audio signal.
Female XLR input, unbalanced
Note: In the case of an XLR to XLR bal-
anced line (i.e., differential) cable the
shield should be left disconnected on one
end (usually on the end connected to an in-
strument output). This helps to prevent
ground loops.
