mAUDIO IN CH 1/2 connectors, FRONT/REAR/ LINE switches, and MIC +48V/OFF/• switches

AUDIO IN (audio input) CH 1/2 connectors (XLR type, 3-pin)

These connectors input external audio signals.

FRONT/REAR/LINE (audio signal selection) switches These switches make settings for the respective audio signals input from the AUDIO IN CH 1/2 connectors. FRONT: Selects the audio input from the video camera as

the audio signal.

REAR: Outputs the audio signal input from the AUDIO IN connector to the CCU. Gain control setting for the connected microphone must be made on the CCU.

LINE: Sets the level for the signal input from the AUDIO IN connector to –20 dB.

MIC +48V/OFF/• (microphone power supply mode) switches

The following power supply settings can be specified for the external microphone:

MIC +48V: +48 V is supplied to the external microphone through the AUDIO IN connector. Set to this position when the microphone requires +48 V of power supply.

OFF: No power is supplied through the AUDIO IN connector.

•: +12 V is supplied to the external microphone through the AUDIO IN connector. Set to this position when the microphone requires +12 V of power supply. This position becomes selectable when the S2 switch on the MA-128 internal board is set to ON (page 9).

Note

Supplying power whose voltage does not match the requirement to the microphone may damage the microphone. Be sure to set the MIC +48V/OFF/• switches to match the power requirement of the microphones.

nREMOTE connector (8-pin)

Connects an RCP-750/751/920/921 Remote Control Panel or RM-B150 Remote Control Unit. Connection must be made with a cable of 150 feet (50 meters) or less in length.

Notes

•The REMOTE connector cannot be used when a CCU is connected.

•When connecting the RM-B150, use the cable supplied with the RM-B150.

oRET CTRL (return control) connector (6-pin)Inputs the control signal for selecting the return video and for turning the intercom microphone on and off.

pEARPHONE jack (mini-jack)

rPOWER switch Selects the power supply.

CCU: Power is supplied from the CCU.

OFF: Standby mode.

EXT: Power is supplied from the DC IN connector.

sLEVEL (intercom level) switch (for the CA-590P)Selects the reception level adjustment method for the intercoms connected to the INCOM 1/2 connectors. REAR: Select this position to adjust the reception level of

the intercoms using the PGM1/2 controls, TRACKER control, ENG control, and PROD control independently.

FRONT: When this position is selected, audio volume of the program, reception level of the intercom connected to the TRACKER connector, and the reception level of the engineer's line and the producer's line are adjusted at one operation using the control on the video camera.

tPGM1/2 controls (for the CA-590P)

These controls adjust the audio volume of the program. PGM1 control adjusts the program audio input from the INCOM1 connector and the PGM2 control adjusts the program audio input from the INCOM2 connector.

uTRACKER control (for the CA-590P)

Adjusts the reception level of the intercom connected to the TRACKER connector.

vENG (engineer) control (for the CA-590P)Adjusts the reception level of the engineer's line.

wPROD (producer) control (for the CA-590P)Adjusts the reception level of the producer's line.

xMIC (microphone level) switches (for the CA-590P)Select the connection line of the intercom microphone independently for the intercoms connected to the INCOM 1/2 connectors.

PROD: Connects the intercom microphone to the producer's line.

ENG: Connects the intercom microphone to the engineeer's line.

OFF: Cuts the intercom microphone connection.
