aTALLY lamp and TALLY switch

When the TALLY switch is ON, the TALLY lamp lights when a red tally signal, green tally signal, or call signal is input from the CCU.

Turning the S101 switch on the internal AU-294 board to ON mixes and outputs the battery alarm signal to the TALLY lamp.

bRET 1 button, RET button and RET 2/3/4 switch

RET1 (return video 1) button

While this button is pressed down, the return video1 signal from the CCU (camera control unit) can be monitored in the viewfinder or on a monitor connected to the RETURN connector.

RET (return video) button

While this button is pressed down, the return video signal from the CCU can be monitored in the viewfinder. Select the monitored signal with the RET 2/3/4 switch.

RET 2/3/4 switch

Selects the return video signal to be monitored in the viewfinder while the RET button is pressed down.

cLIGHT switch

Turns the backlight on the upper part of the panel and the light on the connector section on or off. Depending on the switch position, both lights turn on, only the light on the connector section turns on, or both lights turn off.

dPGM (program audio) 1/2 level controls (for the CA-590)

These controls adjust the audio volume of the program. PGM level controls are provided for both intercom 1 and 2.

eTriax connector

Connects a CCU-550D/550DP/590/590P/700A/700AP/ 790/790P Camera Control Unit through a triax cable.

fINCOM level controls, PROD/ENG switches, and MIC LEVEL switches (for the CA-590)

INCOM (intercom) level controls

These controls adjust the audio reception level of the intercom 1/2.

PROD/ENG (producer/engineer) switches Select the line for the microphone of the intercoms connected to the respective INCOM connectors. PROD: Selects the producer’s line.

ENG: Selects the engineer’s line.

MIC/LEVEL (microphone/intercom level) switches The MIC and LEVEL settings specify the following functions:

ON/REAR: Turns on the intercom microphone. Adjust the intercom reception level with the INCOM level control.

OFF/REAR: Turns off the intercom microphone. Turn the intercom microphone on and off using the control on the external equipment connected to the RET CTRL connector. Adjust the intercom reception level with the INCOM level control.

OFF/FRONT: Turns off the intercom microphone. Turn the intercom microphone on and off using the control on the external equipment connected to the RET CTRL connector or the VTR S/S switch on the video camera. Use the control on the video camera to adjust the intercom reception level. Depending on the video camera, intercom reception level adjustment requires menu operation.

gINCOM (intercom) 1/2 connectos

Connect headsets to enable the reception of program/ intercom audio and transmission of intercom audio.

Set the S3 switch on the internal MA-128 board to “CM” when using headsets with a carbon-type microphone, and set it to “DYN” when using headsets with a dynamic-type microphone.

The INCOM 1 connector can be used for communications through the engineer’s line even though the power to the camera is turned off on the CCU-550D/550DP/590/590P/ 700A/700AP/790/790P.

hTRACKER connector (10-pin)

Used for communications with a tracker and intercom 1 and 2 communications. Also outputs the up tally and program audio signals. The maximam current output from this connector is 500 mA. Settings regarding the input/ output signals can be made on the internal AU-294 board.

iDC IN (direct current input) connector (4-pin)Connects an AC adapter or battery case. Supplies power to the CA-590/590P when the POWER switch is set to EXT.

jRETURN (return video output) connector (BNC type)

Outputs the return video signal.

kPROMPTER (prompter video signal input/output)

connector (BNC type)

Inputs and outputs a prompter video signal. Use the S301 switch on the DM-139 internal board to select the transmission direction (input or output) of the prompter video signal. When the setting is made on the camera adaptor, the transmission direction must be also changed on the CCU.

lDC OUT (direct current output) connector (4-pin)Outputs a direct current of 10.5 V to 17 V at a maximum rated current output of 1.5 A. Connecting equipment with a power consumption greater than the maximum rating will activate the protection circuit, cutting off the current flow.
