1. Adjusting Tape Speed (DECK 2)

Requirements

•

Measuring Device: WOW & FLUTTER Meter (Frequency Counter)

Test Tape: TTA-100 (3 kHz)

Test Point: HP OUT (J101)

Adjustment Point: SFR 1

1) Connect the WOW & FLUTTER Meter to the HP OUT.

2) Insert the test tape (TTA-100) into DECK 2, FWD playback the centre of the tape and adjust SFR1 until

it becomes 3,000 Hz

5 Hz.

3) RVS playback and check that

45 Hz is added according to the FWD speed.

2. Checking Tape Speed (DECK 1)

Requirements

Same as number 1

1) Insert the test tape (TTA-100) into DECK 1, playback the centre of the tape and check that the speed is

within

45 Hz according to the speed of DECK 2.
