Adjustment procedure

Adjustment condition

Step 1

. Disconnect the connecting cables of rear panel. . Connect the frequency counter to the TP50

(C5)/SSP-11 board.

. Check that the frequency at TP50 (C5) satisfies the

following specification (47999.76 to 48000.24 Hz). If the specification are not satisfied, adjust the

CT401

(C4)/X403*2 (C4).

. SAMPLING FREQ. switch(Front panel)

: 48 kHz

Specification (frequency at TP50) Fs (48 kHz) = 48000.00 ±0.24 Hz

Step 2

The settings remain in the same as step 1 except the following.

. SAMPLING FREQ. switch(front panel)

. Check that the frequency at TP50 (C5) satisfies the

following specification (44099.78 to 44100.22 Hz). If the specifications are not satisfied, adjust the CT402*1 (D4)/X404*2 (D4).

: 44.1 kHz

Specification (frequency at TP50) Fs (44.1 kHz) = 44100.00 ±0.22 Hz

5-2-3. RF PLL Adjustment

The RF PLL block generates the clock for extracking the playback data from the head. In correspondence to the head/RF amplifier characteristics, adjust the RF PLL block to obtain the best error rate. Perform this adjustment when replacing SSP-11 board and RF PLL block components, and replacing the mechanism assembly, drum assembly and RF assembly.

Preparation

. Disconnect the connection plugs (COP401 and COP402)

from the connection pins (COR401 and COR402) (D6) on the SSP-11 board. (See “Adjustment Location”.) The connection plugs (COP401 and COP402) are to be reinserted after the RF PLL adjustment.
