Page 20: Mounting The 803
Note: If the mounting location for the 803 provides access to the back panel controls and connectors, you should be able to mount the 803 at this time. Otherwise, perform the connections and adjustments as described in the following sections before mounting the 803.
Page 21: J101 Connector
If you are connecting a powered channel, termination is usually accomplished by the power supply. The 803 has built-in dc isolation, and so it is not neces- sary to use isolation capacitors when connecting to a pow- ered intercom channel.

To change this, see "Mic Select Setup", page 48. The IHM gain is adjusted via the IHM trimmer on the back panel. The standard 803 uses a 5-pin connector for J202. This connector is used for headsets without a mic switch.
Page 34: Miscellaneous Connections
Connect the intercom channel to the remote listener's station. When connecting both local IFB channels and standard intercom channels to the 803, it may be convenient to use splitters. An example for 2-wire ap- plications is shown in Figure 22, page 42. For a 2- wire IFB channel, use the appropriate pins at the J101 connector, page 21.
Page 35 MRT-327 intercom stations conference on channel 1. Channel 2 of each intercom station communicates with the 803 on a private channel. The PS-31 provides power to the intercom stations on channel 1 and also provides the 200-ohm line termination for this channel. The 4012 provides a separate 200-ohm line termination for each of the twelve channels of the 803 that communicate separately with each intercom station.
Page 36 (channel 1 or channel 4). This channel is not available to the 803's. Each 803, however can selectively communicate with any of the 4 in- tercom branches on a private channel.
Page 37 Figure 17. A balanced, 2-wire intercom system using only 803 intercom stations. Each intercom station can talk and listen to any one or combination of intercom stations. A 200-ohm resistor is connected across each 2-wire channel to set the terminating impedance. By adding another 4025A interconnect panel, the system could be ex- panded to 12 stations.
Page 38 Talent 7 Figure 18. IFB panel emulation with 803 Master Stations. In this example, the 803 stations are equipped with op- tional IFB1 and IFB2 connectors. Twelve front panel buttons emulate a Model 4002 IFB panel. Each 803 may send IFB selectively to any of the 8 talent locations or to all 4 talent stations on each 4010, or to all 8 talent stations.
Page 39 Figure 19. ISO panel emulation with 803 Master Stations. In this example, the 803 stations are equipped with op- tional ISO1 and ISO2 connectors. Twelve front panel buttons emulate a Model VCP-12 ISO panel. Each 803 may selectively ISO any of the twelve cameras. Note that in this configuration, channels 1 through 6 are still available for use as 2- or 4-wire intercom channels.
Page 40 IFB1 and ISO1 connectors. Six front panel buttons emulate a Model 4001 IFB panel, and six emulate a VCP-6 ISO panel. Each 803 may send IFB selectively to any of the 4 talent locations or to the stage announce output of the 4010.
Page 41 J101 and J105. In this application, the 4-wire talk outputs are connected using J101. The only rea- son for doing this is to also provide access to the keying outputs of the 803. For example, it may be necessary to key a radio transmitter when talking to it.

Page 45: Buffer Recall Setup
To quit setup mode tap the CALL & SETUP button. Note that you must quit, then re-enter setup to assign additional unused channels. 3.4.7 BUFFER RECALL Setup Buffer recall is a convenient way to assign the current on/off settings for all talk and listen buttons to any one of the PRE 1 through PRE 6 preset buttons.
Page 46: Call Disable Setup
CALL DISABLE Setup 3.4.9 This feature disables or enables call signal reception on se- lected channels. When call signal reception is disabled on a channel, there will be no chime tone or button flash to indicate an incoming call. Outgoing call signals are not af- fected.
Page 47: Local Ifb Setup
IFB channel normally sends a program feed to a re- mote listener. By pressing the talk button for the local IFB channel, the 803 station operator can interrupt the pro- gram feed and then talk to the remote listener. If the IFB channel is configured as a 2-wire channel, either the pro- gram 1 or 2 input can be selected as the program source.
Page 48 *, 0, and # buttons will then display the program source being used with that button. 3.4.21 MIC SELECT Setup This feature selects which microphone inputs are acti- vated by the PANEL ON button in both the on and off po- sitions.
