Crownʼs new CTs series of power amplifiers are remarkable for their loud, punchy sound; sustained, tight bass; and superior protection against overheating and overload. This paper explains the design features behind those advantages. After reading this information, youʼll know why Crown CTs amps sound better than the competition. CTs amplifiers can provide large amounts of power into various loads, such as 2, 4, 8 ohms and 70V. With most power amps, the maximum output power tends to drop as the load impedance increases. But with the CTs series, the power stays the same at almost any impedance. 2-ohm Dual (per Ch.) 250W 4-ohm Dual (per Ch.) 600W 8-ohm Dual (per Ch.) 600W 16-ohm Dual (per Ch.) 300W 70V Dual (per Ch.) 600W 4-ohm Bridge 500W 8-ohm Bridge 1200W 16-ohm Bridge 1200W 140V Bridge 1200W Crown switching power supply for less weight Sustained Power on long-duration signals due to regulated, "stiff” power supplies with incredible energy storage (huge filter capacitors). Extra Hidden Power during high-level transients and during incomplete use of all the channels. Overheating and overload protection thanks to the sophisticated TLC circuitry which compresses the signal only when needed. Compression is controlled not by temperature, but by signal voltage. This keeps the loudness up during compression more than with competitive amps. | 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.

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.
