Yamaha PC6501N

A full model revision takes Yamaha's high-end PC-N power amplifiers to the next level - the PC-1N Series. The new PC-1N Series amplifiers feature an extraordinarily solid low end, rich midrange, and superbly defined highs. They also deliver fast response and exceptional stability even in the face of serious power supply limitations. Refinements throughout this expanded five-model lineup make these amplifiers the new benchmarks for quality, reliability, and versatility in professional applications.

Three Drive Modes Mean Maximum Application Flexibility
All PC-1N models feature stereo, dual mono and bridged mono modes for extra versatility. In the stereo mode the two channels are independent. The parallel (dual mono) mode allows a single mono input signal to drive both channels and two independent speaker systems. And in the bridge mode, both channels work together to deliver maximum power. The rear panel MODE switch lets you change modes quickly and easily.
The PC3301N was specially designed to drive high-impedance loads with multiple parallel-connected 100-volt line speakers, for use as a distribution amplifier in installations.

Multiple I/O Connections Plus Subsonic Filter
A comprehensive array of rear-panel terminals and connectors lets you use the PC-1N Series amplifiers with the widest possible range of systems and equipment. Balanced XLR (XLR3-32) and Euroblock terminal inputs allow quick, easy connection. All models also come with a built-in high-pass (subsonic) filter that cuts frequencies below 20 Hz. 5-way heavy-duty binding-post terminals and Speakon™ connectors ensure solid, reliable speaker connections. All models are equipped with a lockable/detachable power supply connector.

Remote Amplifier Monitoring/Control Via a CobraNet™ Network
Each PC-1N Series amplifier can be connected to a Yamaha ACU16-C amplifier control unit (optional) and Windows-based computer via a rear-panel RJ-45 connector to allow monitoring and control of amplifiers and speakers. You can set amplifier ID via a 5-bit DIP switch, so up to 32 PC-1N units can be serially connected via one ACU16-C. If a protection system is activated in any of the amplifiers the NetworkAmp Manager software running on the system computer automatically displays a pop-up warning window and logs the current parameters for quick, easy troubleshooting, even in complex amp systems. The optional NHB32-C Network Hub/Bridge can be used to monitor/control the entire system via CobraNet™ — while well as using the ACU16-C as a high-quality 24-bit DA converter.

Easy-To-Read Indicators and Comprehensive Protection Circuitry
The PC-1N features an impressive array of protection circuitry and indicators for stable operation and accurate monitoring. The 10-segment LED level meters on the front panel ensure accurate level monitoring even under poor lighting conditions. If output distortion exceeds 1% the red CLIP indicator lights and the PC limiter activates automatically. DC voltage protection activates the speaker protection circuitry and causes the PROTECTION indicator to light if surges of excess current are detected. The high-efficiency EEEngine simply won't overheat under most circumstances, but the TEMP lamp will light if heat sink temperature rises above 85 degrees cersius. At temperatures over 90?? degrees celsius the thermal protection circuit automatically shuts down the system. The 31-step 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 that a "stand-by" command has been received from an external control unit. And the REMOTE indicator on the rear panel illuminates when control signals are received from an external device connected to the DATA port.
