7 Power amplifier indicators
• PROTECTION indicator
The PROTECTION indicator lights in red when the
protection circuit of the internal power amplifier works.
• CLIP indicator
The CLIP indicator lights in red when the output level of the
internal power amplifier is excessive such that the output
signal is distorted.
Notes
When the PROTECTION indicator lights
The protection circuit operates (PROTECTION indicator
lights) and the speaker and amplifier are protected from
damage by decreasing or cutting the output signal in case of
the following:
• If the temperature of the heat sink inside the amplifier
exceeds the specified value.
The connected speaker impedance is too low.
Air intake and exhaust holes (on the right and left sides of
the SRP-X700P) are choked by dust.
• The SPEAKERS terminal is short-circuited.
In such a case, turn the POWER button to the OFF position
and remove the cause of the fault before using the unit
again.
• If DC voltage appears in the SPEAKERS terminal due to
failure.
Turn off the POWER button and contact your local Sony
Sales office or Dealer.

qs USB terminal
Connect the SRP-X700P to a computer in which the supplied
software (SRP-X700P Manager and User Control Panel) is
installed using the USB terminal.
qd SCENE RECALL button
You can recall the scene memories A to D.
Use the SRP-X700P Manager to assign the scenes to the scene
memories A to D.
By default, the scene memory A is assigned to scene No. 1, the
scene memory B is assigned to scene No. 2, the scene memory
C is assigned to scene No. 3 and the scene memory D is
assigned to scene No. 4.
Features
The SRP-X700P is a versatile digital powered mixer that
incorporates an audio mixer, RGB/video switcher, processor
and power amplifier in the 3U rack size.
Built-in digital mixer
The digital mixer incorporates A/D and D/A converters operating at
24 bit/48 kHz sampling and a high-performance DSP. In addition to
the usual functions of conventional ordinary audio mixers, the
SRP-X700P offers functions such as a feedback reducer in the
independent channel and automatic mixing by using digital
technology.
Many audio input/output terminals
Six microphone input systems and two stereo line input systems
can be freely assigned to ten output systems.
Support for RGB/Component signals
The SRP-X700P is equipped with three composite/S-video input
systems and three RGB/component input systems. This broad input
system eliminates need for a separate RGB switcher and video
switcher and enables simple system configuration. The SRP-X700P
supports high-resolution component signals such as 480 p and
(1280 × 1024 pixels) of RGB
1080 i, and also supports SXGA 1)
signals.
Built-in power-saving digital amplifier
A power amplifier of 150 W + 150 W (8 Ω) or 200 W + 200W
(4 Ω) is incorporated. The rated power consumption is almost two-
thirds that of the conventional amplifier. The SRP-X700P also
supports high impedance speakers 150 W (70 V LINE, 32 Ω).
Support for 5.1-channel audio input
4D and 4E INPUT terminals of LINE4 INPUT terminal support
5.1-channel audio input.
Useful external remote terminal
• RS-232C terminal
This terminal enables outside personal computer and system
controller to control various operations of the SRP-X700P. This
terminal can also be used to turn on the power of a Sony
projector and plasma display, or put it in STANDBY. It also can
be used to select the input signals.
• Equipped with Control S output terminal
Basic operations (playback, stop, fast forward, rewind, etc.) of
the Sony AV products are possible.
• Equipped with parallel input and output terminals
Input selection, volume control and scene control of the SRP-
X700P can be performed in the input terminal. Operation of
environment equipment such as screen and lighting, and the
status display of the SRP-X700P can be performed via the output
terminal.

wireless tuner units WRU-806B (option)
Mountable in the EIA standard 19-inch rack

Setting up and operating the SRP-X700P using the
supplied software
The CD-ROM supplied with the SRP-X700P contains two software
applications. One is the User Control Panel that enables an external
personal computer to perform basic operations (sound volume
adjustment, input selection and scene control) of the SRP-X700P
and also the basic operations (playback, stop, fast forward, rewind,
etc.) of a Sony DVD, VCR, CD and MD. The other is SRP-X700P
Manager, which enables you to perform internal settings of the
SRP-X700P.

1 POWER button and POWER indicator
Pressing the POWER button turns on the power. The POWER
indicator lights in green when the power turns on.
You can switch the projectors and displays connected to the
SRP-X700P, to power-on state or to power standby state from
the SRP-X700P as they are interlocked by the SRP-X700P
Manager setup.
By default when shipped from the factory, the projectors and
displays powers are interlocked with the POWER button of the
SRP-X700P.
Turning on the POWER button of the SRP-X700P, sets the AV
equipment connected to the CONTROL S OUT terminals 1
through 4, to power-on state. Note that the AV equipment does
not enter the power standby state when the POWER button of
the SRP-X700P is turned off.
2 Input faders
• MIC1/WL1 and MIC2/WL2 faders
Adjusts the level of the signals supplied from the MIC1/
WL1 and MIC2/WL2 input terminals.
Either a wireless microphone or wired microphone can be
connected. When the wireless tuner receives the signal, the
wireless microphone is selected automatically.
• MIC3 and MIC4 faders
Adjusts the level of the signals supplied from the MIC3 and
MIC4 input connectors.
• MIC5/LINE1 and MIC6/LINE2 faders
Adjusts the level of the signals supplied from the MIC5/
LINE1 and MIC6/LINE2 input terminals. The MIC/LINE
selector button on the rear panel can be used to switch the
reference input level.
By default, LINE is selected.
• LINE3 and LINE4 faders
Adjusts the level of the signals supplied from the LINE3
and LINE4 input terminals.
These input faders are not the "moving" type.
