Series 6385 Stereo Encoders

INTRODUCTION

The Series 6385 Stereo Encoders are designed for cable television headends that must encode locally-originated or satellite-

delivered stereo audio programming into BTSC stereo format. They are economical, top-of-the-line encoders with superior

performance specifications and unsurpassed interfacing flexibility. Two models support NTSC and PAL-N video formats

respectively.

DESCRIPTION The Series 6385 Encoder encodes stereo audio signals into the BTSC multi-channel television sound format. The encoder uses the dbx noise reduction system as required by the BTSC standard. The Model 6385 Encoder accepts discrete left/right stereo and/or SAP audio as standard inputs. Available outputs include a wideband BTSC encoded baseband signal and a 4.5 MHz subcarrier for use with a wide variety of video equipment.
