The Datasat RA7300 Multi-Channel Power Amplifiers bring a new level of quality and flexibility to high-end home theatre and multi-channel music systems. Perfect for anything from small media systems to dedicated top of the line home cinemas or even to outfit an entire home, its advanced circuitry and careful design delivers one of the industry's most powerful, versatile and quietest power amplifiers.
The RA7300 is designed to be versatile and is rated for 4 and 8 ohm loads. With a rated output of 300 watts RMS into seven channels at 8 ohms, the RA7300 is powerful enough to deliver consistently excellent performance in any system. The RA7300 amplifier is deigned to complement Datasat's RS20i high-end audio processor.
OVERVIEW
Great condition pre-owned Datasat RA7300 Multi-Channel Power Amplifier in black finish.
unit comes with original box, power cord, and manual.
Rated 8/10 for minor cosmetic ware consistent with age and use.
FEATURES
-
The quietest amplifiers available: Dual thermal sensors, one for each channel or channel bank, control a very low speed fan with substantial heat sinks. The fan only operates when program material requires additional cooling to ensure any fan noise is always masked by the content. In this way, the RA7300 delivers a signal-to-noise ratio of >125dB ('A' weighted, referenced to full output).
-
Innovative, modular design: Each RA7300 amplifier channel is designed complete with the power supply on a single printed circuit board. Separate power supplies for each channel minimise crosstalk, noise and distortion. This approach provides for ease of replacement and system maintenance.
-
Enhanced versatility: The RA7300 is rated for 4 and 8 ohm loads. It delivers 7 channels of 300 watts RMS power at 8 ohms. It delivers 450 watts RMS at 4 ohms.
-
Extended connectivity: The RA7300 features DB25 connectors with pass-through and channel ID selections that mate perfectly with the Datasat RS20i audio processor. It also includes balanced XLR and unbalanced RCA connectors.The RA2400 features DB25 connectors with pass-through and channel ID selectionsthat mate perfectly with the Datasat RS20i audio processor. It also features balanced XLR and unbalanced RCA connectors.
-
Consistent, thermal-independent operations: The RA7300 amplifier uses dual-DC servos to ensure that DC offset is at a minimum and thermal-track transistors maintain the amplifiers at their optimum bias point independent of amplifier temperature. The amplifiers operate without current limiting.
-
Advanced circuitry: The fully balanced differential topology of the RA7300 doubles amplifier slew rate and reduces noise by half. It uses current feedback to increase amplifier speed.
-
Efficient standby: The Datasat RA7300 amplifier meets or exceeds all international standards for standby power consumption including the new 122 watt standard.
