Note

For control of an LCD Data Projector VPL-PX15, use the CONTROL S connectors instead of the PROJECTOR CONTROL RS-232C connector.

NSYSTEM TYPE selector

Can be set to positions 1-9, according to the speaker configuration of the AV system being used. (Select position 0 only when setting the system type using the SRP-X500P Manager software.)

The setting becomes effective next time the power is turned on. Thus, change the setting while the SRP-X500P is turned off.

For details on the various system types, see “Selection of system type” (page 19).

OIR OUTPUT MODE (remote programming) button

Used to program an SRP-X500P command to an optional remote commander with leaning capability.

For details on how to program an optional remote commander, see “Programming a remote commander” (page 28) and refer to the Operating Instruction supplied with the remote commander.

PMicrophone input adjustment section

+48V (48 V DC power supply) ON/OFF switches: Set

to ON to supply 48 V DC power to condenser microphones connected to the MIC INPUT 1 to 4 connectors. These switches are factory-set to OFF.

Note

Before turning these switches, be sure to fully turn down all input level controls and the LINE AV/RGB controls, or turn off the unit.

TRIM (microphone input reference level adjustment) controls: Set the reference level for signals input from the MIC INPUT 1 to 4 connectors. The settable range is –60 dBu to –30 dBu.

Notes

•A reference level cannot be set for signal input from tuner units installed to the SRP-X500P.

•The TRIM controls treat their adjustable signal range as two areas (one is between –60 dBu and –50 dBu and another is between –49 dBu and –30 dBu) and because of this, sound dropouts may be observed while adjusting the reference level for the signal input from the microphones. However, this is not a malfunction.

REF. (reference level) indicators: Light up yellow when the audio signal whose level exceeds the reference level is input to the MIC INPUT 1 to 4 connectors. While the audio signal is input, adjust the TRIM

controls so that the REF. indicators light up yellow intermittently.

FEED BACK REDUCER (howling suppressor) buttons: Used to turn the howling noise reducing function on or off, and to make settings for the function. The buttons light up green when the function is turned on.

For details on the settings, see “To suppress howling” (page 22).

QRS-232C indicator

Lights up green when the SRP-X500P and a PC or external controller are communicating via the REMOTE RS-232C connector.

RPROJECTOR ON/STANDBY POWER switch Turns on the projector or the display monitor connected to the SRP-X500P or sets the projector or the monitor to standby status. Press the switch while it is lighted up red (i.e., the projector or display monitor is in standby status) to turn the projector or display monitor on. The switch lights up green when the projector or the monitor is turned on.

To turn off the projector or the monitor, keep pressing the switch for more than 2 seconds. The switch flashes green while the projector or the monitor cools off, and then lights up red when the projector or monitor enters standby status.

Notes

•If you turn on the projector or display monitor or change the input setting by operating it directly or by using the remote commander supplied with it, the PROJECTOR ON/STANDBY switch indication and actual status of the projector or display monitor may become unmatched.

•If you attempt to turn on the projector or display monitor while it is cooling off, it may not respond. Turn it on again after the projector or display monitor finishes cooling off and enters standby status.
