NSC1
Stereo Coder

This is a high performance Stereo Generator built into a one- rack space unit. Its stereo separation performance is higher than 60 dB with S/N higher than 85 dB. A high sensitivity VU meter allows accurate measurement of audio input levels. The two balanced audio inputs (XLR Connectors) are filtered from RF interference. The very low distortion (typical 0.05 dB) makes this low cost generator comparable in performance to the more expensive digital equipment.
