As a leading manufacturer in the A/V industry, Sony offers a wide range of
public address and sound reinforcement products utilizing sophisticated Sony
audio, wireless and interfacing technologies to provide a comprehensive business
and industrial product line.
In 2002, Sony introduced an innovative all-in-one system concept for multimedia
presentations, the SRP-X700P Digital Powered Mixer. Designed to function as
the central control hub for the integration of video, audio and PC media sources,
this mixer allows for rich content and multimedia presentation systems to be
easily configured, without integrating several separate A/V presentation devices.
Best suited for use with in mid- to large-scale conference rooms, seminar rooms,
and audio-visual rooms, the SPR-X700P is now widely accepted in many different
arenas including education, and the corporate and public sectors.
In 2005, expanding on this all-in-one concept,Sony introduced the SRP-X500P.
This cost-effective mixer is an ideal choice in small to mid-scale presentation
systems that are typically used in conference rooms, corporate boardrooms,
classrooms, and houses of worship.
Soon after the launch of the SRP-X500P, however, system integrators and
installers were confronted with questions: What is the best choice for a specific
application – the SRP-X500P or the SRP-X700P? What are the differences
between these two mixers?
Tohelp answer these questions, this guide provides the following useful
information:
•Using the maximum functionality and performance of the SRP-X500P
•Understanding the differences between the SRP-X500P and the SRP-X700P
•Establishing an effective system using the key features of the SRP-X500P
•Professional audio terminologies related to the SRP-X500P and SRP-X700P
We hope this guide serves as a valuable asset to your SRP Series system

SRP-X500P System Integration Guide
4-1. SYSTEM TYPE
What is a “SYSTEM TYPE”?
The SRP-X500P offers nine factory default system settings
called “SYSTEM TYPE” in its memory, enabling efficient
audio adjustment. Depending on the type of room,
speaker locations, and speaker system configurations, you
can quickly configure an audio system by recalling the best-
suited preset for each venue. If your requirements cannot
be managed by one of the nine system presets provided,
you can easily customize all system settings using the
supplied SRP-X500P Manager software.
SYSTEM TYPE 1, 2 (for AV Presentation Rooms)
SYSTEM TYPE 1 and 2 are suitable for AV presentation
rooms. This type of room needs clear voice reproduction
from microphones, and vivid sound from AV equipment
such as DVD and CD players. Satisfying both requirements,
the following may be the best speaker configuration:
• Output microphone audio from ceiling speakers to
enhance clarity
• Output AV equipment audio from the front speakers in
stereo
For ceiling speakers, both multi-connected high-impedance
speakers and high-quality low-impedance speakers can be
used.
The SRP-X500P is equipped with a four-channel digital
power amplifier (SP1 to SP4). Low-impedance speakers can
be connected to SP1 and SP2, while SP3 and SP4 can be
switched between high- and low-impedance modes. This
means you can configure systems as follows:
• SYSTEM TYPE 1: a pair of front speakers and
high-impedance ceiling speakers (70V Line)
• SYSTEM TYPE 2: a pair of front speakers and
low-impedance ceiling speakers (Lo-imp)

SYSTEM TYPE 4, 5 (for Conference Rooms)
SYSTEM TYPE 4 and 5 are well suited for conference
rooms. This type of room mainly needs clear voice
reproduction from microphones. In these rooms, the
speaker system consists of ceiling speakers. Audio from AV
sources is mixed to monaural, and is output from all power
amplifiers (SP1 to SP4).
• SYSTEM TYPE 4 uses only SP3 and SP4 outputs, and
consists of high-impedance ceiling speakers (70V LINE)
• SYSTEM TYPE 5 uses all outputs from SP1 to SP4, and
consists of low-impedance ceiling speakers (Lo-imp)
SYSTEM TYPE 3, 6, 7, 8, 9
(for Audio-Visual Rooms)
SYSTEM TYPE 3, 6, 7, 8, and 9 settings are suitable for
audio-visual rooms. This type of room mainly needs vivid
audio reproduction from AV equipment such as DVD and
CD players. In these rooms, ceiling speakers are not used.
Audio from microphones is output from front speakers and
satellite speakers. So, speaker output should be adjusted
to be heard evenly anywhere in the room.
In a long length audio-visual room, locating satellite
speakers in the middle of the room is an effective way of
maintaining sufficient sound pressure at the rear of the
room, while suppressing excessive sound pressure close to
the speakers. SYSTEM TYPE 6 to 9 settings fit such rooms,
and are selected depending on the distance between front
speakers and satellite speakers.
By adding delay to satellite speakers according to their
distance from front speakers, users can compensate for
audio delay, allowing clear audio reproduction throughout
the room. For more details on the delay feature, please
refer to the appendix.

4-2. Feedback Reducer
The SRP-X500P is equipped with an independent feedback
reducer function on each microphone channel, helping to
achieve optimum sound quality. In multimedia presentation
systems, it’s not unusual for microphones to be located
within the speaker coverage area (sometimes in front of a
speaker), and howling may occur when the distance
between a speaker and microphone is too close. In the
past, howling has been typically suppressed by making
repeated manual adjustments to a graphic equalizer, but
this manual operation takes a long time as the user must
detect the frequency bands in which howling occurs. Now,
with the SRP-X500P, howling is easily and quickly
suppressed by the built-in feedback reducer function. For
an explanation of howling, please refer to the appendix.
1Adjust the TRIM
volume while
talking on a wired
microphone, or

SRP-X500P System Integration Guide
5-1. Automatic Gain Control (AGC)
It is often difficult to appropriately adjust microphone
volumes when picking up voice. This is because speaking
volumes differ from person to person, and depend on the
distance between each presenter’s mouth and the
microphone. The Automatic Gain Control (AGC) function
is convenient for maintaining an optimum audio level by
reducing speech volume differences. AGC can be set using
the supplied SRP-X500P Manager software. For more
details on AGC, refer to the appendix.
■Setting
1. Set the overall audio volume. The speaker output
level should be adjusted beforehand so that the audio
can be heard evenly anywhere in the room.
2. Set the AGC to ON. Left click the AGC button on the
OVERVIEW screen to display the AUTO GAIN
CONTROL setting screen. Click the ON button to turn
on the AGC function.
3. Initially set the GATE THRESHOLD level to -50 dB.
4. Adjust the COMPRESSOR THRESHOLD level so that
the GAIN CONTROL meter reads between -5 and
-10 dB when talking on a microphone in a loud voice.
At the same time, adjust the RATIO so that the voice
can be clearly heard. As a rough guideline, set it
between 3:1 and 10:1.
5. Adjust the MAKE GAIN
so that the compressor
characteristics line is at
0dB IN/0 dB OUT.
6. Adjust the GATE THRESHOLD level so that the gate
does not open with the ambient noise level present
during a presentation.
7. Adjust the RANGE level so that the ambient noise is
not completely muted. At the same time, confirm
that the gate opens when you talk into the
microphone. If you lower the volume too much, the
timing to open the gate will be delayed when you
talk on the microphone. This may cause a
momentary microphone off when starting to speak.
8. Adjust the ATTACK, HOLD, and RELEASE times.
ATTACK time means the response time when the gate
opens or the compressor works. As a rough
guideline, set it to 50 ms or less.
HOLD time suppresses the rapid change of gain by
maintaining the condition of the gate and
compressor. 10 ms to 100 ms may be a suitable
value. If you want to eliminate any unnatural sound
that may occur for a short duration just after talking,
set a short HOLD time value. If the gate closes
between words while speaking, set a longer value.
RELEASE time is the response time it takes from the
gate opening and closing, the compressor stopping,
and the gain returning to normal. 100 ms to 300 ms
may be an appropriate value. If the level rapidly
changes and the voice is interrupted, set a longer
RELEASE time. If you are worried about the noise
made by the gate closing, set a shorter time.
9. Setting is now complete, so close the AGC screen.

5-2. Delay
The SRP-X500P is equipped with a four-channel power
amplifier. By utilizing all amplifiers, you can configure a
multiple speaker system with the SRP-X500P. When you
select SYSTEM TYPE 0 to configure your audio-visual room,
adelay setting is required to compensate for the distance
between front speakers and satellite speakers. Delays can
be set on the OVERVIEW screen of the supplied SRP-X500P
Manager software.
■Setting
1. Measure the distance between the main speakers and
the satellite speakers (e.g. 10 m).
2. Select meters or feet from the drop-down list in the
UNIT setup box. Then input the value in the SP3 and
SP4 DELAYboxes.
3. By setting the delay parameter a little longer than the
actual measurement, you can get more natural audio
from front speakers. Select ms from the drop-down
list in the UNIT setup box.Then add 10 to 20 ms to
the SP3 and SP4 DELAY value (e.g. 20 ms).
4. Listen to the audio. If it sounds normal, the setting
is complete.
If you find the audio from the front speakers and
satellite speakers is not unified, the delay parameter is
too great. Reduce its value gradually, and check by
listening. If sound is located at the mid-point between
the left and right satellite speakers, the delay parameter
is too small. Increase its value gradually.
