PRODUCT OVERVIEW

The TASCAM 322 is designed to offer the simplicity of a standard dual cassette deck, yet the sophistication for the most demanding A/V installation. Optical leader sensing allows the deck to minimize the play or record time lost in reversing tape direction. The two tape decks can operate independently with their own audio I/O or they can work together for dual recording of a single master. Built-in cascade out and transport logic also allows multiple machines to be used in duplication rigs or logging set-ups. The 322 comes equipped with an RS-232 control port for use with advanced control systems, and optional slot for the LA-322 Balancing Kit.
