Calibrating The Series 200 Mixer - Tascam M-200 Series Owner's Manual

CALIBRATING THE SERIES 200 M I X E R
I
Calibrating your Series 200 Mixer is the pro-
cess of matching i t s output to the rest of the
equipment being used in the system. In this
example we will assume you are using a four
track recorder, the 234 Syncaset. The method
l
used here can be used with virtually any type of
1
equipment you are likely to encounter.

The first step is to connect the PGM OUT-
puts from the Series 200 to the inputs of the
recorder. Once the equipment is connected, you
can begin the calibration. A test tone generator.
TO-122A, or test tape is handy to have for this
purpose. I f you have a constant tone test tape
skip to step number 12 in the following se-
quence. Assuming you have a tone generator,
or constant tone tape, set the frequency t o
1 kHz then proceed as outlined below:
1. Connect the tone source t o the channel 6
LINE INput. Any channel will do, we picked
channel 6
a t
random.
2. Set the EQ and PAN t o the 12 o'clock posi-
tion.
3. Press both Assign switches, 1-2 and 3-4.
4. Raise the channel 6 fader to the shaded
area between
7
and
8.
5. Raise the PGM 1
-
4 faders to the shaded
area between
7
and
8.
6 . Set the channel 6 TRIM to 12 o'clock posi-
tion.
7. Raise the channel 6 fader until meters 1
-
4 read O VU. The channel fader should be in the
shaded area. If i t isn't adjust the TRIM contro1
until it is correct. Use the PAD also if necessary.
8.
Raise the input level controls on the front
panel of the Syncaset recorder until the re-
corder's meters read O VU.
9. Using a fresh tape, record the O VU tone on
al1 four tracks for about a minute.
1 0. Disconnect the tone source, and connect
the outputs of the recorder t o the first four
TAPE I Nputs of the Series 200 Mixer.
11. Make sure al1 EQ controls are
a t their
12
o'clock settings.
12. Rewind the tape and play the tone. Set
the recorder's output level controls so that the
recorder's meters read O VU.
13. Pan channel 1 full left, channel 2 full
right. Turn off the 3-4 Assign switch in channels
1 and 2.
14. Pan channel 3 full left, channel 1 full
right. Turn off the 1-2 Assign switch in channels
3 and 4.
15. Raise the channel 3 and 4 faders until the
meters read O VU. Do the same for channels 1
