Sansui QS-800A

Description

The QS-800A is a combination of Sansui's new QS matrix system 4-channel decoder and a high performance 200 watt stereo amplifier to amplify the rear channel signals for 4-channel sound reproduction.

The decoder features the exclusive QS Vario-Matrix circuitry which provides optimum separation among the reproduced sounds.

When added to a present stereo system, this decoder and the rear channel amplifier will work together to (1) decode encoded 4-channel program sources back into 4-channel, and (2) transform (synthesize) conventional 2-channel sources into 4-channel.

The QS-800A as a whole also offers complete provisions for reproducing discrete 4-channel program sources and for reproducing 2-channel sources in 2-channel stereo if you so desire.

As such, it is the most complete, most authentic means of upgrading your stereo system to immediate 4-channel status.
