Calibration (CR-4)

The CR4 provides facilities for manual calibration.
to match the deck to a wide variety of tapes. For
best results, perform calibration before starting to
record.
0 Before doing the calibration. turn off the Dolby
NR switch.

0 The position of the Monitor switch has no effect
on calibration. The output is switched off.

0 While the Calibration switch of the CR4 is set
to "On," regular playback or recording is not
possible. Take special care not to inadvertently
set the switch to "On" during normal recording.

as a test tone will be recorded in such a case.
Always set the switch to "0" when calibration
is not being performed. To prevent noise tran-
sients from reaching the output. a muting circuit
is active for a few seconds when the Calibration
switch is operated.

Insert the tape to be used for recording and set the
Tape Selector and Eq switch to the required posi-
tions. Then set the Calibration switch to "On."

Set the deck to the record mode and start the tape.
A test tone is now being recorded. and the results
are shown on the peak level meters, which assume
a special function during calibration.

First adjust the bias current to achieve flat frequency
response. Turn the Bias control until the indication
of the upper and lower meter bars becomes equal.
The upper bar corresponds to high-range response
and the lower bar to low-range response.

Next. adjust the overall level to match the sensi-
tivity of the tape. Turn the Level control until the in-
dication of the lower meter bar matches the "Cal"
mark. The upper bar should now also be approxi-
mately at the Cal" mark.

If there is a notable difference in upper and lower
meter readings. readjust the Bias control until both
bars match the Cal" mark. This completes the
calibration procedure.

Set the Calibration switch to ".Off" The tape is au-
tomatically rewound to the beginning (or to the zero
point of the tape counter, if Memory Stop is ac-
tivated).
