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.
