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.
