ABD-8A Analog Balanced Drive

The Sensurround ABD-8A is a high performance multichannel balanced drive stage for home theater and professional monitoring applications. It accepts up to eight separate unbalanced audio signals and drives an equal number of balanced lines. The electrical performance, including frequency response, crosstalk, noise and distortion, are unmatched. The transparency and absence of any coloration or degradation produce an auditory experience that is breathtaking.

Careful attention to detail and liberal use of shielding have made the ABD-8A one of the quietest units on the market. By using only the highest quality components and employing rigorous production testing, each unit can be offered with a 3 year warranty.

The A version provides 3dB lower output noise relative to the original ABD-8.

  • Selectable gain of 2 (6dB) or 4 (12dB)
    switchable in 4 sets: Ch. 1/2/3, Ch 4, Ch 5/6, Ch 7/8
  • High drive capability for use with long cable runs
  • Large headroom, can faithfully pass 10Vrms differentially
  • Capable of driving all outputs into 600 Ohms simultaneously
  • USB port for monitoring channel levels
  • External power supply for minimum hum and noise
  • Ferromagnetic enclosure virtually eliminates external interference

Applications
The high performance of the ABD-8 makes it ideal for use in high-end home theater installations when it is necessary to drive long lines and reduce noise pickup from lighting systems or other interference. The performance and high drive capability allow easy adaptation of home-theater surround-sound decoders to broadcast or recording studio use.
