PC-1N Series Power Amplifiers

The new PC-1N Series power amplifiers had a lot to live up to. As the next generation in Yamaha's flagship PC lineup, they would be expected to deliver the same exceptional standards of separation and response, while taking sound quality to the next level. Yamaha engineers examined every detail of the circuitry, and how each affects sound quality. This in-depth analysis led to important innovations in circuitry and internal wiring. Meticulous part selection - including environmentally friendly lead-free parts - was part of the process as well. New circuit board mounting methods were developed to absorb unnecessary vibrations, and feedback from sound professionals in the field was analyzed and refinements implemented wherever necessary. The results were worth it: unprecedented sound quality with the lowest possible distortion. Clear and transparent, yet powerful and solid. The PC-1N Series features dynamic, deep, detailed sound with exceptional balance.

The PC-1N series features smaller components throughout thanks to the improved efficiency achieved by the new switching regulator and EEEngine technology. Smaller part size, in turn, gave Yamaha engineers new freedom in component layout, offering a wider range of alternatives in choosing parts, circuit design, and internal layout that could be implemented to maximize sound quality and reliability. As you can see in the photo below, PC-1N models feature a performance-enhancing symmetrical layout. Circuit boards prone to heat generation, for instance, have been located on both sides of the amplifier with large heat sinks and low-noise variable-speed cooling fans. This arrangement also absorbs vibration that can result in unwanted noise. Also, heat sinks are mounted to the side panels with insulated screws to eliminate chassis resonance that can cause noise.

An advanced Yamaha switching regulator and high-efficiency EEEngine technology give the PC-1N Series amplifiers high-quality sound and exceptional power with dramatically reduced power consumption and a new compact size. The switching regulator stabilizes output voltage and current … even when line voltage varies … for maximum drive efficiency. This means that, unlike conventional linear power supplies that use a transformer, the switching regulator guarantees dynamic reproduction with faultless stability even at high output levels. This improved efficiency is also the key to other important PC-1N features such as reduced heat generation, longer component life, lighter weight, more compact dimensions, and lower power consumption. Expect clear, stable, high-quality sound in installed systems with long power cables as well as large-scale outdoor live sound applications with unstable primary power sources. EEEngine technology further reduces power consumption without sacrificing sound quality. An independent auxiliary power line and high-speed voltage buffer guarantee split-second response to fast sound transients. New MOSFET (Metal Oxide Semiconductor Field Effect Transistor) circuitry in the high-efficiency current buffer boosts PC-1N Series efficiency by as much as 200% - that's 50% lower power consumption - over conventional class-AB amplifiers. * The PC9501N, for instance, draws a mere 950 watts of power with both channels driven at maximum power into 4-ohm loads. * Comparison with previous Yamaha class-AB amplifiers.

Amp Editor is a dedicated software application for PC-1N amplifiers that makes amplifier management easy. Remotely control and monitor PC-1N amplifiers simply by connecting your amplifiers to an Ethernet port on a computer via a standard high-speed Ethernet switch. Connection to the Amp Editor network requires no special drivers so that your system is up and running in no time. All PC-1N amplifier functions and DSP parameters can be controlled using Amp Editor.

- Remote monitoring and control via CobraNet™ Network -The NetworkAmp Manager is a software application that lets you monitor, manage, and control Tn series and PC-1N series amplifiers connected to a network via the ACU16-C and NHB32-C. The software runs on Windows based computers, and can be used to control a system of up to eight NHB32-C hubs, sixteen ACU16-C control units, and as many as 512 power amplifiers. Simply connect your computer's COM or USB port to any ACU16-C or NHB32-C on the network, and use the software's efficient, intuitive graphical interface to remotely monitor and control each networked device.
