P-Series power amplifier 350 watts RMS x 2 at 8 ohms (450W x 2 at 4 ohms)
Our take on the Yamaha P3500S by Crutchfield's Dave Delamere
When you're up on stage, you don't want to worry about having enough power for your speakers and monitors. With the robust power from Yamaha's P-Series amplifiers, you won't have to worry. They work effectively in a wide variety of venues, such as dance clubs, music halls, convention centers, and houses of worship. Their strong power output, versatile channel configurations, and portability make them a great choice for any event.
A blend of features and performance
The rear panel inputs and outputs accommodate a wide variety of pro audio gear.
Yamaha's P3500S amp delivers 350 watts RMS per channel at 8 ohms, 450 watts per channel at 4 ohms, and up to 2000 watts bridged at 4 ohms. EEEngine (Energy Efficient Engine) technology effectively reduces AC power consumption and heat generation without sacrificing power output. Combine that with its variable-speed cooling fan, and you get an amp that runs cool, only drawing big-time current when it needs it. The gain controls and variable high-pass and low-pass filters let you pair these amps with just about any non-powered speakers. Yamaha's YS processing balances the power output to perfectly match the power handling of Yamaha's Club Series speakers.
Yamaha's P3500S amp includes balanced XLR and 1/4" TRS inputs, as well as 5-way binding posts, 1/4" outputs, and Neutrik Speakon® outputs for the speakers. Rack mounts are included, so you can install multiple amps in one rack to power your multi-speaker setup.

P-Series Power Amplifier: The Yamaha P-Series P3500S power amplifier delivers solid, professional-quality power in a wide range of configurations designed to suit a variety of applications. The unit offers three operating modes - Stereo (350W x 2ch in 8Ω or 450W x 2ch in 4Ω), Parallel (350W x 2ch in 8Ω or 450W x 2ch in 4Ω), and Bridge (900W x 1ch in 8Ω).
- Stereo: In Stereo mode, Channels A and B operate independently (as with a conventional stereo amplifier). The Channel A input goes to the Channel A output jacks, and the Channel B input goes to the Channel B output jacks.
- Parallel: In Parallel mode, the unit outputs a mono source
through twin amplifier systems. 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: In Bridge mode, the unit operates as a single high-power amp. The Channel A input signal is output from the Bridge output jacks. To adjust the volume, you must use the Channel A volume control knob.
Note: The amplifiers two output channels have independent volume controls (31-step) located on the front-panel.
Inputs/Outputs: To provide the most versatile connectivity possible, The P3500S is equipped with Neutrik Speakon output jacks and 1/4" output jacks for each channel, in addition to 5-way binding posts. Balanced XLR and 1/4" TRS phone jacks are provided for channel inputs A-B.
High-Pass & Low-Pass Filters: The Yamaha P3500S is equipped with independent high-pass and low-pass filters on each channel, so you can optimize the output for a subwoofer or full range system. The high-pass and low-pass filters are variable (25-150Hz).
Perfect Match for Yamaha Club Series Speakers: Yamaha's audio engineers have specifically designed the new P-S Series power amplifiers to be perfect companions to the popular Club Series loudspeakers. To achieve this, they made sure that the amplifiers are capable of delivering power that matches the power handling capabilities of the Club Series Speakers, and equipped them with YS Processing (Yamaha Speaker Processing) to deliver a signal that will result in optimum system performance. The P-Series power amplifier can also be used with practically any loudspeaker PA system.
EEEngine (Energy Efficient Engine) Technology: EEEngine (Energy Efficient Engine) Technology makes more efficient use of AC power by reducing power consumption and heat generation without sacrificing output power or sound quality. When power requirements are low, the system uses a highly efficient current buffer to transparently switch input power on and off as needed. As power requirements increase, an independently responding auxiliary power line supplies additional power as required. Output isn't compromised because the auxiliary power line is driven by the power supply voltage which maintains maximum output to the speaker load.
Protection Circuitry + Cooling Fan: Comprehensive protection includes power on/off muting, DC detection, thermal protection, current limiting, and a protective cover for the attenuators. The Protection indicator lights up and sound output is automatically muted whenever the unit's protective circuitry is operating. The amplifier also features a variable cooling fan for quiet, efficient cooling. The Temp indicator lights up if the unit is running hot.
Rack Mountable: The Yamaha P3500S power amp is rack mountable with a 2U chassis size.
