J. IEC AC Power Inlet

Accepts an IEC AC power cord. The DBC Network Bridge has a universal power supply, and may be operated on AC line voltages from 100 VAC to 240 VAC at 50 Hz or 60 Hz.

K. Multifunction Control Port

One DB37M for analog inputs, digital inputs, +5VDC, +10VDC and ground. 8 input-switch closures, 8 analog 0-10VDC inputs, 16 output contact closures, +10VDC power source (1A), GND (1A+).

L. Primary Network Connector

RJ45 connector for primary CobraNet network connections (100Mbit CAT 5). Supports TCP/IQ communications with CobraNet digital audio channels.

On the connector are two LEDs (see detail drawing below). The left LED lights yellow when the port is in use and will blink if the device is also the conductor (the CobraNet timing master device). The right LED lights green when link is established and blinks when network activity is detected. Both LEDs flash yel- low in unison to report a fatal error.

M. Secondary Network Connector

RJ45 connector for secondary (redundant or backup) CobraNet network con- nections (100Mbit CAT 5). Supports TCP/IQ communications with CobraNet digital audio channels.The SECONDARY connection is similar to the Primary, but is active only in case of a fault in the CobraNet network attached to the PRIMARY. The secondary LEDs work in the same way as the primary ones.

N. AES/EBU Digital Audio Input

DB25 female connector accepts eight AES3 digital audio signals. Pinout matches Dolby #778 AES input/output card for CP-650.

O. Analog Audio Input

DB25 female connector accepts eight balanced analog line-level analog inputs. Pinout matches Dolby CP-650 analog output.

P. Aux Input Level Controls

Screwdriver-set, calibrated gain potentiometer (one per channel) for adjusting the input gain to the input signal level. These can be used to compensate for different microphone sensitivities. Control range is from –12 dB to +20 dB.

Figure 4.2 Back Panel Controls and Connectors

Q. Aux Inputs

2 female XLR balanced inputs for speech reinforcement or announcements. Switchable between mic, line, and mic with phantom power.

R. Monitor Out Connector

3-pin Phoenix-type connector supplies a balanced analog line-level output signal which can feed a powered monitor loudspeaker. This output can be switched to monitor:

•Cinema processor output signals (+20 dBu maximum output level)

•Pre-amp input signals

•Post-amp output signals

S. Aux Input Mic/Line/Phantom Switch

Each input has a three-position “M L P” selector switch for mic level, line level, or mic level with phantom power.

•Select the M position for microphone signal levels up to +7dBu (0 dbu = 0.775 volt).

•Select the L position for line level signals up to +32 dBu

•Select the P position for mic inputs that require +24 VDC phantom power.
