Yamaha PC6501N: Power Amplifier
Maximum sound quality with minimum distortion for a new dimension in powerful, clear sound: From the start, the new Yamaha PC6501N had a lot to live up to. As the next generation in Yamaha’s flagship PC lineup, it had to deliver the same exceptional standards of clear separation and rapid response while taking sound quality to the next level. Yamaha audio engineers went to work examining every detail of sound quality. Which led to breakthrough-level innovations in circuitry and internal wiring. Meticulous part selection — including environmentally friendly leadfree parts — and innovative combinations. And new circuit board mounting methods to absorb unnecessary vibrations. They also analyzed feedback from public address professionals on-site and tested prototypes with commitment bordering on obsession. The results were worth it. Results like the highest level of sound quality with the lowest level of distortion available. Clear and transparent, yet powerful and robust. A responsive, dynamically energetic low range, rich, mellow mid range and high-resolution high range. The bottom line? The Yamaha PC6501N features dynamic, deep, detailed sound with exceptional balance — the kind of performance that "runs in the family".

New advanced switching regulator and high-efficiency EEEngine technology: Thanks to Yamaha’s advanced new switching regulator and high-efficiency EEEngine technology, the Yamaha PC6501N features high-quality sound and exceptional power with slashed power consumption and new compact size. The switching regulator stabilizes output voltage and current — even when line voltage varies — for maximum efficiency drive. Which means that, unlike conventional linear power supplies that use a transformer, the switching regulator guarantees balanced sound with no instability even at high output levels. What’s more, the improved amp drive efficiency as a result of the switching regulator is the key behind other important Yamaha PC6501N features like reduced heat loss, longer part life, lighter weight, more compact size and lower power consumption. And thanks to the advanced switching regulator and other refinements, the Yamaha PC6501N’s switching regulator features the highest performance ever — clear, stable, high-quality sound in installed sound systems with long power cables and outdoor, large-scale public address applications with unstable primary power sources. Next, EEEngine technology is the key to slashing power consumption without sacrificing sound quality. The independent auxiliary power line and highspeed voltage buffer feature split-second response capabilities to fast attack sound. What’s more, new MOSFET (Metal Oxide Semiconductor Field Effect Transistor) circuitry in the high-efficiency current buffer is why the Yamaha PC6501N boosts efficiency to a phenomenal 200% — 50% lower power consumption — over conventional Class-AB amplifiers.
Easy-to-read indicators and comprehensive protection circuitry: The Yamaha PC6501N features an impressive array of protection circuitry and indicators to ensure stable operation and accurate monitoring. The front panel’s 10- segment LED level meters guarantee accurate level monitoring — even under poor lighting conditions. If output signal distortion exceeds 1%, the red "CLIP" indicator lights and the PC limiter activates automatically. In terms of DC voltage protection, surges of excess current activate the speaker protection circuitry and cause the "PROTECTION" indicator to light. What’s more, the high-efficiency EEEngine prevents against overheating under almost any circumstances. However, the "TEMP" lamp illuminates if heat sink temperature rises above 85. And at temperatures over 90, the thermal protection circuit automatically shuts down the system — for a fail-safe protection environment.
There’s more. The 31-step-detented level controls for channels A and B come with a security cover to prevent control settings from being changed accidentally. The "POWER/STAND-BY" indicator does double duty; green means the power is on, while orange notifies users of a "stand-by" command from the connected external control unit. And the "REMOTE" on the rear panel illuminates when control signals are received from an external device connected to the DATA port.
Three drive modes guarantee maximum application flexibility: All PC-1N models feature stereo, dual mono and bridged mono modes for the ultimate in versatility. In the Stereo mode, the two channels are independent. The Parallel (dual mono) mode allows a single, mono input signal to drive two independent speaker systems. And in the Bridge mode, the two channels work together as one, pumping out maximum power. What’s more, the rear panel MODE switch lets you change modes quickly and easily for top versatility any time, anywhere. In terms of individual model capabilities, the Yamaha PC3301N was specially designed for use as a distribution amplifier to drive multiple speakers in installed sound systems based on its ability to drive highimpedance loads using multiple 100-volt line output speakers in parallel..
Multiple I/O connections plus subsonic filter cut unwanted low frequencies: The comprehensive array of rear panel terminals and connectors let you use the Yamaha PC6501N with the widest possible range of systems and equipment. Balanced XLR (XLR3-32) and Euro-block terminals are featured as inputs for quick, easy connection. All Yamaha PC-1N models also come with a built-in high pass (subsonic) filter that eliminates frequencies below 20Hz. On the output side, 5-way heavy-duty binding-post terminals and Speakon™ connectors ensure solid, reliable speaker connections. Finally, all models are equipped with a lockable/detachable power supply connector.
Remote amplifier monitoring/control with cutting-edge CobraNet™ audio networking interface: Each Yamaha PC-1N model can be connected to a Yamaha ACU16-C amplifier control unit (optional) and Windows PC through its rear-mounted RJ-45 connector — to let you monitor/control the amplifiers and speakers connected to it. You can control AMP ID settings with the unit’s 5-bit DIP switch and up to 32 PC-1N serial interface connections with one Yamaha ACU16-C. If a protection system is activated in any of the amplifiers, the PC’s NetworkAmp Manager software automatically displays a pop-up warning window and logs current parameters for quick, easy trouble shooting — even in complex amp systems. What’s more, the NHB32-C Network Hub/Bridge (optional) lets you monitor/control the entire system via CobraNet™ — as well as using the ACU16-C as a high-quality 24-bit DA converter.
