Double System Sound

By Sweetwater on April 15, 1998

A method of producing sound motion pictures where the sound track is recorded on a magnetic tape recorder that is synchronized with the movement of the film in the camera. The synchronization is done by recording a special tachometer signal on one track of the tape. This signal is generated by the camera and is at 60 Hz when running at 24 f.p.s (the standard frame rate for film). When the tape of the sound track is played back, the sync signal is sensed by a device called a resolver, which adjusts the speed of the tape player to match the speed of the movie projector.

Offer applies only to single-receipt qualifying purchases. No interest will be charged on the promo balance if you pay it off, in full, within the promo period. If you do not, interest will be charged on the promo balance from the purchase date. The required minimum monthly payments may or may not pay off the promo balance before the end of the promo period, depending on purchase amount, promo length and payment allocation.

The estimated required monthly payment shown which excludes taxes and delivery equals the amount financed divided by the number of months in the promo period, rounded up to the next cent. During the last month(s) of the promo period the required monthly payment may be reduced due to this rounding. These payments apply only with the financing offer shown. If you make these payments by the due date each month, you should pay off this amount financed within the promo period, if it is the only balance you are paying off. If you have other balances on your account, this payment will be added to any other minimum monthly payments.
