Datasat - RA2400 - 400 Watt 2-Channel Stereo Power Amplifier

Datasat - RA2400 - 400 Watt 2-Channel Stereo Power Amplifier

The Datasat RA2400 Stereo Power Amplifier combines innovative design with advanced circuitry to deliver outstanding audio performance. Ideal for high-quality home theatre installations as well as 2 channel audiophile music systems the sound reproduction is refined and pure. Datasat has produced one of the industry’s quietest and most powerful, quiet and musical 2 channel stereo amplifiers.

The fully balanced differential design of the RA2400 doubles amplifier speed (slew rate) while reducing noise by 50%. It uses current feedback to increase amplifier speed while the dual-mono design ensures each channel is completely independent with separate power supplies. This minimizes crosstalk, noise, and distortion.

The Datasat RA2400 features a unique amplifier design using 940 small storage capacitors situated close to the output transistors for faultless operation. With up to 20 output devices per channel, each channel of the RA2400 has its own specifically designed bridge rectifier for smooth AC to DC conversion.

Any number of Datasat RA2400 amplifiers can be operated without thermal issues – the amplifiers are maintained at their optimum bias point independent of their temperature. All parts within the amplifier have no thermal limitations. Its fully integrated power supply for the input stage features 7 independent regulators for continuous operation.

Delivering extended versatility, the Datasat RA2400 produces 400 watts of power rated at 8-ohm loads. For high power performance at low impedance, it is capable of continuous operation at 600 watts rated at 4 ohms.

The RA2400 amplifier is designed to complement Datasat’s RS20i high-end audio processor as well as the RA7300 multi-channel amplifier providing the ultimate listening experience for luxury home cinema.
