4. Set all INPUT selector switches to TAPE position.
5. Initially, set all input FADERS at nominal (#7 to #8).
NOTE: The TRIM controls have no effect when-the unit is
operated in this configuration.
6. Initially, set all 4 CHAN BUSS PAN pots at center.
7. Set the MASTER 1-2 FADER at nominal (# 7 to #8).
8. Press the PLAY button, causing tape to roll.
9. Gradually bring up the monitor amplifier volume until the
desired level is heard. (Alternately, if listening with head¬
phones, adjust the HEADPHONE volume control CW
from OFF position).
NOTE: Both channels will have the same program
(mono), and relative balance probably will be incorrect at
this point.
10. Set the 4 CHAN BUSS selector to 1-2 of channel 1 and
those of other channels 2 through 4 to OFF position and
the channel 1 fader to nominal position.
11. Adjust the 4 CHAN BUSS PAN pot on channel 1 to place
the program from track 1 anywhere from left to right in
the stereo perspective.
12. Adjust the channel 1 EQ controls as desired to:
a) obtain the most pleasing sound quality,
b) reduce leakage of unwanted sound in the channel, or
c) improve separation from other channels by accenting
or minimizing parts of the frequency sjDectrum.
13. Set the 4 CHAN BUSS selector of channel 1 to OFF posi¬
tion and that of channel 2 to 1 -2 and bring up the fader of
channel 2. Repeat steps 11 and 12 for channel 2, and for
each of the remaining channels, thus creating a stereo
panorama of the various acoustic images.
14. Bring up all four channel input FADERS to nominal set¬
ting; then move them down (or up) as required to balance
the level between tracks. Observe the VU METERS to
ensure that the level peaks between - 3 VU and 0 VU
in both the 1 (track 1) and 2 (track 2) meters; the red peak
indicator LEDs should flash only once in a while.
NOTE: The 3 and 4 meters will be inactive in this mode;
only the 2 channels are being monitored.
15. If necessary, adjust the MASTER 1 -2 FADER to obtain the
correct VU indications, with these exceptions:
a) If the MASTER FADER must be set below #6, instead
reset it at It 7 and lower all four input FADERS suffi¬
ciently to obtain the optimum level.
b) If the MASTER FADER must be set between # 9 and
#10, instead reset it at #8 and raise all four input
FADERS sufficiently to obtain the optimum level.
NOTE; If the speakers are too loud or too quiet, adjust
the monitor amplifier volume (or if phones are used,
adjust HEADPHONE volume).
16. Rewind the tape (press ZERO RETURN or REWIND then
STOP). If desired, press PLAY, and recheck the balance
and sound quality. When ready, rewind again and pro¬
ceed.

17. P lace the stereo master recorder in record ready mode.
(Press record/pause, or whatever mode permits the
record levels to be adjusted without rolling tape.)
NOTE: Steps 17, 18 and 19 enable the proper record level
to be set. The Model 250 controls are adjusted so the 1 &
2 VU METERS indicate a suitable output level, and the
monitor speakers or phones level may appear to be cor¬
rect, yet none of this ensures proper recording levels;
these are set on the stereo master recorder.
