The SRD-1 is the industry standard TV stereo decoder for critical measurements. It serves a dual-role as a stereo measurement instrument and an audio-quality monitor. And the SRD-1 offers full compliance to BTSC standards yet works with test equipment already owned by most stations, saving costs over other BTSC-capable monitors.

A TV station can calibrate the SRD-1 to verify its performance to BTSC Recommended Practices. Its performance has not only been field-tested, but has also been verified by an independent Professional Engineer. A copy of the full report is available from Modulation Sciences at no cost.

The SRD-1 lets users select four operating modes: Equivalent mode: either sum and difference or left and right and BTSC mode: sum and difference or left and right. It also has selectable deemphasis and two independent sets of audio outputs -- precision and balanced line. Two preset inputs allow for rapid selection between two composite stereo sources.

The SRD-1 maintains performance over temperature and has a test set-up to permit field verification of performance. SRD-1 achieves laboratory accuracy at a modest price that is half to a third what other BTSC capable monitors costs. SRD-1 is unique in being the ONLY television stereo decoder delivering laboratory grade performance independently -- without reference to the encoder.

The SRD-1 is simply the most accurate way to assure a TV station's stereo performance and compliance.
