AC Power Connection/Control

The AC connection is an integrated connector/

switch/fuse holder to allow for greater reliability and
safety.

1

AC Connector

IEC standard 3-prong connector.  The center post is

chassis ground.  When power is not connected, the unit
is bypassed, i.e., the audio inputs are connected to the

audio outputs through a relay.

2

Power Switch

This controls the AC power into the BD500.  When

the power switch is off, the unit is bypassed.

3

Fuse Holder

1-Amp Slow Blow fuse.  You should always replace

it with the correct value.  This fuse interrupts the AC

power.  Removal or destruction of this fuse will cause
all operation to stop and will cause the bypass relay

to close, connecting the XLR audio inputs to the XLR
audio outputs.  This does not guarantee that high volt-
age will not be present in the unit.  Always disconnect

the line cord from the AC connector before removing
any cover or panel.

Standard and Optional Remote Control and
Signalling

The BD500 has a standard remote control/signalling

output.  This allows remoting of the dump and sneeze

functions and output of safe status  (see Appendix B.)
The optional remote control card (see Appendix C) al-

lows RS-232 remote control, relay/dry contact remote
control of front panel functions, relay drivers for ex-
ternal signals and lamps, and additional commands

not available from the front panel.

4

RS-232 Connector (optional)

This is a female 9 pin DB9 connector supplied to con-

nect a remote computer or terminal.  The remote
computer or terminal can control all functions of the

BD500 including configuration.  See Appendix E.

5

Remote Connector

This is a female 15 pin DB15 connector  for connec-

tion of external signalling (buttons, indicators,
telephone cut-off).  See Appendices B and C.

6

Auxiliary Connector (optional)

This female 25-pin DB25 connector is used for de-

laying control signals by the delay amount.  See
Appendix D.

Optional AES/EBU - Digital Audio In/Out

These optional connections are used to connect pro-

fessional digital audio gear to the BD500.  These cables
are differential with a shielded twisted pair.

7

Input data, XLR (optional)

The BD500's connector is female.  Pin 1 is shield, 2

and 3 are differential.

8

Output data, XLR (optional)

The BD500's connector is male.  Pin 1 is shield, 2

and 3 are differential.

Analog Audio Inputs and Outputs

XLR differential audio connections for two input

channels and two output channels.

9 and 10   Channel 1 and 2 Outputs

Male XLR connectors.

11 and 12  Channel 1 and 2 Inputs

Female XLR connectors.
