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 amplifiers.
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.
