Location and Function of Parts
MIC 3: Adjusts the level of the signal input from the MIC
INPUT 3 connector.
MIC 4: Adjusts the level of the signal input from the MIC
INPUT 4 connector.
LINE: Adjusts the level of the signals input from the
LINE IN connectors.
AV/RGB: Adjusts the level of the signals input from the
AV/RGB INPUT audio connectors, as specified by the
J AV/RGB SELECT buttons.
F Input indicators
SIGNAL (signal level) indicators: Light up green when
the signal is input from each audio connector.
RF (radio frequency) indicators: Light up green when
the level of the RF signal input from each tuner unit is
satisfactory.
AF (audio frequency) indicators: Light up yellow when
the signal is input from each tuner unit.
G SPEAKER OUTPUT indicators
PROTECTION (protection circuit) indicator: Lights
up red when the protection circuit of the internal power
amplifier operates.
CLIP (clip) indicators: Light up red when the output
level of the internal power amplifier is excessive and
the output signal is distorted.
70V LINE (high-impedance speaker connection)
indicator: Lights up green when the SPEAKERS
CH-3/4 terminals are set to connect high-impedance
speakers (70V LINE).
VU (volume unit) meters: Uses 5-segment LEDs to
indicate the signal output level prior to adjustment by
the L SPEAKER OUT controls.
Note
When the internal protection circuit operates, the signal
output is cut to protect the speakers and the SRP-X500P
from being damaged.
• If any of the following conditions arises, turn off the
SRP-X500P and eliminate the cause.
− The temperature inside the amplifier exceeds the
specified level due to excessive output.
− The impedance of the connected speakers is too low.
− The ventilation holes (located on both sides of the
SRP-X500P) are blocked by dust.
− The SPEAKERS terminals are short-circuited.
• When the SRP-X500P does not operate normally after
eliminating the cause, turn it off and contact the Sony
dealer from whom you purchased it.
H MASTER MUTING indicator
Lights up red when signal output is muted by a command
issued from a device connected to the REMOTE
PARALLEL or REMOTE RS-232C connector, or by
operation of an optional remote commander.
I MASTER control
Adjusts the output level of the assigned channels.
With the SRP-X500P Manager software, you can specify
which output channels are controlled by the MASTER
control.
The MASTER control is factory-set to control the output
from the SPEAKERS CH-1 to 4 terminals and the LINE
OUTPUT 1/2 connectors. (Note that the output from the
LINE OUTPUT 3/4 terminals cannot be controlled.)
J AV RGB SELECT buttons (A to E)
Press to select a device connected to the AV/RGB INPUT
audio/video connectors. The pressed button lights up
green.
K LINE AV/RGB input adjustment section
TRIM (input reference level adjustment) controls:
Adjust the reference level for the audio signals input
from the LINE IN connectors and the AV/RGB
INPUT audio connectors. The adjustable range is –
30dBu to 0 dBu.
REF. (reference level) indicators: Light up yellow when
the audio signal whose level exceeds the reference
level is input to the LINE IN connectors and the AV/
RGB INPUT audio connectors. While the audio signal
is input, adjust the TRIM controls so that the REF.
indicators light up yellow intermittently.
L SPEAKER OUT controls
Used to attenuate the output level of the internal power
amplifier.
Before adjusting the speaker output level, use the TRIM
controls to specify the reference level for the audio input
signals, then use the MASTER control to adjust the
overall level. And then use the SPEAKER OUT controls to
adjust output level from the SPEAKERS CH-1/2 terminals
and CH-3/4 terminals.
M PROJECTOR PROTOCOL selector
Used to select the protocol corresponding to the model of
the projector or display monitor connected to the
PROJECTOR CONTROL RS-232C connector or the
CONTROL S IN/OUT connectors. (Select position 0 only
when setting the projector protocol 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 selector position and projector and
display monitor models, see “PROJECTOR CONTROL
RS-232C connector” (page 23) and “PROJECTOR
CONTROL CONTROL S IN/OUT connectors” (page 24).
