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. Frequency Response: 10 Hz – 40 KHz. Output Power: 2 x 500 Watt / 8Ω RMS, 2 x 800 Watt / 4Ω RMS, 1600 Watt / 8Ω bridge RMS. Weight: 12,5 Kg.
The S Series of RAM Audio amplifiers distils all these features to fulfill all your needs, whether youʼre starting a P.A. amplifier project from scratch, or you need to upgrade your present sound reinforcement equipment.
In the S Series amps, you'll find five 2-channel models and five 4-channel models, all offering plentiful power levels at low distortion in the range of 1.5 to 6 kilowatts, yet weighing in around 8 kilos and 30 cm deep.
• Ultra-compact and lightweight 2-U high
• Laser cut aluminum front panels with integrated carrying handles
• Neutrik® XLR input connectors, input and signal link in 2 channel models
• Input Link switch: allow daisy-chaining of the input signal
• Neutrik® Speakon® output connectors
• Detented sealed potentiometers for easy recall of volume settings
• ICL™, PMS™, Hi-temp, Signal indicators per channel
• Power on and Stand-by leds
• Highly versatile with multiple configuration and additional module options
• Full PC control via EtheRAM (with EtheRAM Control module)
• Switchable ICL™ clip-limiters per channel
• Switchable (30-50 Hz) sub-sonic highpass filter per channel
• Three-position gain selector (26, 32 or 38 dB)
• Dual or bridge mode selector
• Twin temperature controlled, back to front cooling fans
• Oversized power components (high SOA reserve specification)
Standard Signal Inputs Module: The S Series amps are equipped as standard with twin Neutrik® XLR, doubled by two other XLR connectors for linking purposes. In the 4 Channel models an XLR input per channel is provided with the signal linking facility.
Analog Processor Module: permits a very easy, user-friendly signal processing to enable the amp to set up a bi-amp system without any other outboard device. These are the Processor's main characteristics:
• 2-way stereo crossover (dual mono or single bridged sub output)
• 24dB/oct Linkwitz-Riley configurable crossover (90, 100 o 120Hz)
• Adjustable attenuation in the High-pass outputs (-3, -6 or -9dB)
• Adjustable Limiter, relative to Max. Output (-3, -6 or -9dB)
DSP44_S Module: Digital Signal Processor fully programmable through an USB port. These are the Processor's main characteristics:
• 4 Inputs/4 Outputs or 2 In/2 Out free route configurable.
• 24 bits/192 kHz 256x Oversampling Converters.
• Output Delay: 0 to 7.1 meters (20.69ms) per channel.
• XOver: Up to 48dB/oct Butterworth, Linkwitz-Riley and Bessel.
• EQ: 9 filters per channel (Parametric, Shelving, LP,HP,BP,SB).
• Gain, Mute and Phase inversion per channel.
• RMS Power and Peak Voltage output limiter per channel.
• Real Time operation from USB or front panel configuration.
