The TCD 910 was intended to replace reel-to-reel and cartridgemachines in many applications. Touting its high specs, the deck was"capable of producing tapes at sound and silence levels beyond thatrequired by broadcast and studio requirements." It offered a real-timecounter and auto-locator functions.
