breaks that connection. Although we have provided this switch to ensure versatility in
any installation, we can conceive of no installation where it would be set to
LIFT.
An RS-232 (PC Remote) Computer Interface on Port 1 is provided to connect the
6200 to IBM PC-compatible computers, directly or via modem, for remote control and
metering. In addition, an RS-232 (PAD) interface on Port 2 is provided to connect the
6200 to a DAB transmitter to communicate with it, providing PAD (Program-Associated
Data) to the transmitter and receiving frame synchronization data from it. Both remote
computer interfaces use DB-9 connectors.
For 6200 OPTIMOD-DAB units only, an optically isolated Remote Control Interface
is provided to connect the 6200 to your existing transmitter remote control. The 6200
remote control supports user-programmable selection of up to eight inputs for any one of
the following parameters: user presets, factory presets, test presets, stereo, mono left,
mono right, analog input, digital input, digital output parameters, low-pass filter. (See
Remote Interface Programming on page 2-36.) The 6200 remote control accepts a DB-25
connector.
Digital AES/EBU Input and Output are provided to support two-channel AES/EBU-
standard digital audio signals through XLR-type connectors. In addition, an AES/EBU
Sync Input is provided to accept house sync, if required
Analog Inputs and Outputs are provided to support left and right audio signals through
XLR-type connectors.
Audio Input and Output Connections
Cable
We recommend using two-conductor foil-shielded cable (such as Belden 8451 or equiva-
lent), because signal current flows through the two conductors only. The shield does not
carry signal, and is used only for shielding.
Connectors
• Input and output connectors are XLR-type connectors.
In the XLR-type connectors, pin 1 is CHASSIS GROUND, while pin 2 and
pin 3 are a balanced, floating pair. This wiring scheme is compatible with
any studio-wiring standard: If one pin is considered LOW, the other pin is
automatically HIGH.
Analog Audio Input
• Nominal input level between –14dBu and +8dBu will result in normal operation of
the 6200.
