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.
