The S Series of RAM Audio amplifiers distils all these features to fulfill all your needs, whether you’re 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.

Features

• 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)

Protections

• PMS™: Power Management System controls the amount of power that the amp delivers under diferent circumstances.

• SSP™: SOA Sentry Protection effectively limiting the power that the amp could deliver into an incorrect load or to a direct short-circuit

• ICL2™: improved Intelligent Clip Limiting

• Input signal muting at turn on

• Thermal overload protection

• Progressive Ramp input signal

Input Module Options

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.

EtheRAM Control Module: permits the control and monitoring of an installed group of 2 channels S series Power Amps, connected to a standard EtherNet LAN using the onboard Datacom port via a Neutrik® RJ-45 connector. Also, it has a general purpose input and output connector to interface with third party controllers like an alarm system. It permits to control the turn on and to report the operating status.

Ethernet Audio Transport (Coming soon): digital audio network interface module which permits the reception of audio signal through an Ethernet network. The network`s own external control system permits signal routing to any of the amp's channels. Two different versions for CobraNet™ or EtherSound™ protocols.

AES/EBU Digital Input (Coming soon): Input for digital audio signal for AES/EBU (AES3) standard via Neutrik® XLR, (extra Link XLR connector fitted). Its Sample Rate Converter permits 16 or 24 bits resolution operation at 32 to 48 KHz Sample Rate.
