After having confirmed that the setting is correct, the mir-
ror tape may warp anyway. In order to establish the titit
angles of the recording/plaback head and the erase head,
adjust (by turning 1/4 — 1/2 turns) the level adjusting screw
(311) of the tape guide (103). Refer to the pages on
“Adjusting and checking the Mechanism Section’’ when
replacing or adjusting the R/P HEAD.

Azimuth
(1)
After

check
load
the
test
tape
(TEAC
MTT-114).
(2) Play back the test tape; adjust the azimuth nut so
that section A of the resurge wave form is maximum
and section B is minimum.
3. Checking and Adjusting the Tape Speed
1) Connect the frequency counter to the LINE OUT
terminal and load the test tape (TEAC MTT-111).
2) Playback a test tape. At about halfway through the
tape, where the tape transport is stable, adjust the
adjustment points on the back of the capstan motor
so that the frequency counter will have a reading with-
in the the range of 3,000 Hz + 6Hz.

4. Adjusting the Input Sensitivity
(1) Set the MONITOR switch to SOURCE position, the
operational mode at STOP. Supply a 400 Hz signal
to the LINE IN terminal and set the input signal level
(approx. —20 dB) so that the output level at the LINE
OUT TERMINAL (L ch) becaomes OdB.

(2) At the same time, check to make sure the R ch output
level is also OdB.

5. Adjusting Playback Section
(1) Adjusting the playback level
Play back the Dolby standard level test tape (TEAC
MTT-150)
and
adjust

so that the LINE OUT voltage becomes 0 dB (0.775V).
(2) Adjusting the playback frequency response
Play back the test tape (A-BEX TCC-262) and check
to make sure that the frequency response meets the
specifications in the diagram.
