Dual C 810
Stereo Cassette Deck (1979)
The C 810 includes every important feature that directly contributes to fine performance and total reliability, with little that might be considered frills. In short, you'll find the 810 the perfect deck if you're looking for your first recorder or if you're simply looking for great value.
Among the many features the 810 shares with the higher priced Dual cassette decks are the Direct Load and Lock system, high torque DC servo control motor with integral frequency generator, twin belt drive system, equalized peak reading meters, logic-controlled intermode switching and foolproof tape protection.
The DLL system is one of those features that will make you wonder why it hasn't been thought of before. Instead of a door that's always in the way of the cassette, you have direct, unimpeded access to the cassette compartment. The necessary protection for the tape heads is provided by a shield that swivels out of the way the moment you switch the machine on. Then you simply place the cassette into the compartment, where it locks in perfect alignment.
To remove or replace the cassette, you just reach for it and pull it out. You can even do that while the tape is in fast forward! The instant your fingers touch the side of the cassette they activate auxiliary stop switches.
The one area where no cassette deck can afford compromise is in its drive system. If that's not reliable, nothing else matters. The 810's drive system has two precision ground belts in a vibration isolating system, plus a high-speed direct-gear rewind and fast forward.
Precise speed control is assured by a high-torque DC servo-control motor whose speed is constantly monitored and instantaneously corrected by feedback from an integral frequency generator.
If a faulty cassette should ever jam or spill, an electronic tape motion sensor automatically stops the transport. So if you've ever been annoyed with such problems, you can now forget them. Thanks to the logic-controlled switching you can go from mode to mode - even to or from fast wind - without going through stop.
