Introduction
Thank you for your purchase of the YAMAHA P7000S, P5000S, P3500S or P2500S power amplifier.
These P-series amplifiers fully incorporate Yamaha’s renown technological expertise, and offer high
reliability, rock-solid stability, and superb acoustic characteristics—all in a trim, 2U-sized package.
Features
• With two types of input jacks (balanced XLR and balanced phone) and three types of output jacks
(Speakon, 5-way binding post, and phone), the P series is suitable for a wide variety of applications
and installed systems.
• The unit offers three operating modes: STEREO (where Channels A and B operate independently),
PARALLEL (where the unit outputs a mono source through twin amplifier systems), and BRIDGE
(where the unit operates as a single high-power amp).
• Each channel is equipped with an independent OFF/LOW CUT/SUBWOOFER switch—where
LOW CUT engages a high-pass filter, and SUBWOOFER engages a low-pass filter. With LOW CUT
or SUBWOOFER selected, you can adjust the cutoff frequency from 25 to 150 Hz.
• Each channel has its own SIGNAL and CLIP indicators.
• The PROTECTION indicator lights up—and sound output is automatically muted—whenever the
unit’s protective circuitry is operating. The TEMP indicator lights up if the unit is running hot.
• Variable-speed low-noise fans ensure high reliability.
This Owner’s Manual covers the four models: P7000S, P5000S, P3500S and P2500S power amplifi-
ers. Please read through this manual carefully before beginning use, so that you will be able to take full
advantage of the amplifier’s superlative features and enjoy trouble-free operation for years to come.
After reading through the manual, please store it in a safe place.

Controls and Functions
■ Front Panel
1 POWER switch and indicator
Press to toggle the power on or off. The POWER indicator
lights up green when the power is ON.
2 TEMP indicator
Lights up red if the heat sink temperature exceeds 85°C
(185°F).
3 PROTECTION indicator
Lights up red to indicate that protection is in effect. Specifi-
cally, lights up if the heat sink overheats, or if a DC voltage is
detected at the amplifier outputs. Also lights up for about three
seconds at time of power-on, as the amp gets ready to operate.
To provide protection, the unit will not output any sound from
the speakers while this indicator is lit up. When start-up is
completed or the problem is corrected, the indicator goes off
and normal operation resumes.
4 CLIP indicator
Lights up red when the output signal distortion on the corre-
sponding channel rises above 1%—indicating that “clipping”
has occurred because the signal level is too high.
5 SIGNAL indicator
Lights up green when the corresponding channel’s output level
exceeds 2 Vrms (equivalent to 1/2 W into an 8 Ω load, or 1 W
into a 4 Ω load).
6 Volume control knobs
Each control knob adjusts the volume of the corresponding
channel, in 31 steps from –
∞ dB to 0 dB.
NOTE:
If you wish to lock in the knob settings, you can fasten the sup-
plied security cover over the knobs so that the settings will not
be disturbed.
How to install the security cover
(1) Use the supplied hex wrench to remove the four attach-
ment screws from the amplifier.
(2) Adjust the security cover to the position of screw holes.
Fasten it into place using the same screws.
7 indicator
Lights up yellow if the YS PROCESSING switch on the rear
panel is set ON. (See page 7.)
8 Air intakes
The amplifier uses forced-air cooling. The cooling fans draw
air in from the front and exhaust it through the rear. Please be
sure that you do not block the air intakes or exhaust vents.
NOTE:
The fans do not come on at initial power-on, but will switch on
automatically when the temperature of the heat sink rises above
50°C (122°F). The fan speed will then vary automatically as
the temperature changes.

■ Rear Panel
1 FILTER switch and FREQUENCY adjustment knob
(One pair for each channel)
Use these controls to select the filter type and adjust the cutoff
frequency on each channel (A and B). You use the FILTER
switch to select the filter, as follows.
OFF ...................... Do not use any filter.
SUBWOOFER..... Use a low-pass filter. The amplifier outputs
the frequencies that are lower than the cut-
off set by the FREQUENCY adjustment
knob.
LOW CUT ........... Use a high-pass filter. You can use this set-
ting to filter out unneeded low or subsonic
frequencies.
If you select SUBWOOFER or LOW CUT, you can then use
the FREQUENCY adjustment knob to adjust the cutoff fre-
quency. The adjustment range is 25 Hz to 150 Hz.
NOTE:
If the amplifer is set to BRIDGE mode, only the switch and
knob for Channel A are effective. (The Channel B frequency
controls are disabled.)
2 ON/OFF switch
If you set this switch ON, the amplifier adds low-frequency
compensation so as to enhance speaker output. The results (the
actual change in the low-frequency balance) will vary accord-
ing to the speaker type. Note that this switch is effective only if
the FILTER switch is set to OFF.
NOTE:
This feature provides improved frequency reponse on speakers
such as the YAMAHA S112 and S115.
3 INPUT jacks (Channels A, B)
Two jack types are provided for each channel. Note that if you
are using BRIDGE or PARALLEL mode, only the Channel A
jacks are effective.

4 STEREO/PARALLEL/BRIDGE switch
Use this switch to select the operating mode.
• STEREO mode
Channels A and B operate independently (as with a conven-
tional stereo amplifier). The Channel A input goes to the Chan-
nel A output jacks, and the Channel B input goes to the
Channel B output jacks.
• PARALLEL mode
The Channel A input signal is output through both the Channel
A and Channel B output jacks. The Channel B input jacks do
not function. Channel A and B volumes can be independently
adjusted.
• BRIDGE mode
The Channel A input signal is output from the BRIDGE output
jacks. To adjust the volume, you must use the Channel A vol-
ume control knob.
