DUAL foto
Mod.C-830
Description

With its three heads and true source/tape monitoring ability, the C 830 will have special appeal to the most serious recording enthusiast. The incoming signal can be instantly compared with the signal actually recorded on the tape.

The Direct Load and Lock system begins the entire recording and playback process by assuring perfect cassette alignment. The four-point tape guidance system assures perfect contact between the tape and heads.

Recordings from discs, broadcasts and other tape recorders can be mixed with the microphone inputs - line and microphone each having its own record-level controls. Headphone monitoring is made more convenient by an independent level control for this output.

The drive system has an extra touch of precision - a phase-locked-loop in the servo control system which reduces wow and flutter to only 0.035 percent. An integral frequency generator provides instantaneous corrections of any deviation from accurate speed. Perfect tape to head alignment is assured by the four-point guidance system. And the electronic sensor constantly monitors the tape tension so that any deviation instantaneously stops the transport.

As you've probably learned from experience, no matter how careful you are when making recordings, especially off-the-air, there are occasional unexpected interruptions and abrupt endings. Since cassettes are not easily edited, you invariably have to live with those unwanted sounds or try to erase the tape at just the right points - assuming you can locate them.

Dual's electronic fade/edit system lets you fade out unwanted materials during playback - while you're listening to the tape. Guesswork and accidental erasure are avoided. And you'll have the satisfaction of knowing that the beginnings and endings of all your tapes are unmarred.

The 830's many other operating features include: six-way bias/equalization; equalized peak-reading LED record-level indicators; two-way memory stop; switch-able multiplex filter; and Dolby noise reduction. In short, just about everything the demanding professional is likely to look for in an advanced design cassette deck.
