FUNCTIONS OF PRINCI PAL
Volume Control ( For Upper Channel 0nly)
and 0n-Off Switch
Clockwise rotation of the Volume knob supplies
power to the entire recorder and simultaneously re-
gulates the volume for both the recording and play-
back operations. Turning the recorder On also auto_-
matically unlocks thetransport mechanism so that the
Function knob may be turned to engage the Record or
Play mode.
NOTE: The automatic tape cutoff switch is elec-
tricallv connected in series with the
power On-Off switch and must be held
in the closed position before power is
supplied to the recorders. The tape
cutoffswitchis held in the closed posi-
tion when either the Function knob is
returned to the Stop position, or when
the tape has been threaded on the mach-
ineforusein the Record or PIay mode,
Engagement of the Rewind or Rapid For-
',vard mode returns the Function knob
to the Stop position, and thus mechan-
ically holds the cutoff switch in the
closed position without interference by
the tape.
Tone Control
Clockwise rotation of the Toneknob regulates the
tone for playback and public address operations only.
The Tone control is disconnected when recording.
Function Knob
A11 electrical and mechanical functions for Re-
cord, Stop, and Play modes are performed by this
single, 3-position knob.
Stop Mode-Turning the Function knob to the
Stop positi6-n
returns the mechanism and associated
amplifier circuitrytothenormal or rest position from
a prevailing engagement of either the Record or play
mode. Also for convenience and protection, a pre-
vailing engagementof theRecordor Play mode is auto-
matically returned to the Stop position whenever the
On-Off switch is turned Off, therebyagaindisengaging
the mechanism from the Ptay or Record mode. With
the Function knob in the Stop position, the recorder
may be used as a public address system.
Record Mode-Turningthe Function knob to the
Record position actuates the mechanism and switches
the electricalcircuitsthat enables the material avail-
ableattheinputjackto be recorded. The Record Lock
Button mu'St firstbedepressedbefore the Record mode
can be engaged. The Record mode cannot be engaged
if the recorder is already engaged in either the Re-
wind or Fast Forward mode - the High Speed Lever
must first be returned to its neutral (center) position
before the Record mode can be engaged.
Play Mode-Turning the Function knob to the
elay poEIE6E aET[ates the mechanism and switches the
electrical circuits necessary to properly ptay back a
recorded tape. The Play mode, Iike the Record mode,
cannot be engaged if the recorder happens to be engaged
4
PARTS ( REFER TO FIG. I)
in either the Rewindor Fast Forward mode - the High
Speed Lever mustfirstbereturned to its neutral (cen-
ter) position before the Play mode can be engaged.
High Speed Lever
This lever controls the high speed transport of
the tape in both the Rewind and Fast Forward modes.
It can be used toskipahead to any point on the tape or
to rewind tape onto the supply reel. By moving the
lever back and forth, the tape can be inched along in
either direction to find arr exact point on the tape.
Rewind Mode-Sliding the High Speed lever to
the ieiT?EGI[6nEechanicallinkages in such a wav as
to cause highspeedtransport of the tape onto the sup-
ply reel. The Rewind mode can be engaged while the
recorderis engagedintheRecord, Stop, or Play mode.
The previousiy engaged mode (either PIay or Record)
automatically releases and returns the Function knob
to the Stop position. To switch from Rewind to the
Fast Forward mode, the High Speed lever must first
be moved to its center position to allow the brakes to
stop the rewind travel of the tape. The High Speed
lever may then be moved to the right to engage the
Rapid Forward mode.
Rapid Forward Mode-Sliding the High Speed
I ever to the?Qht aEGTponE echanical linkages in such
a way as to cause high speed transport of the tape onto
the take-up reel. The Fast Forward mode can be en-
gaged while the recorder is engaged in the Record,
Stop, or Play mode. The previously engaged mode
(either Play or Record) automatically releases and re-
turnsthe Functionknobto the Stop position. To switch
from Fast Forward to the Rewind mode, the High Speed
lever must first be moved to its center position to allow
the brakes to stop the fast forward travel of the tape.
The High Speed lever may thenbe moved to the left to
engage the Rewind mode.
lnstant Stop Button
Pushing this button acts mechanically upon the
mechanismtostopthe tape travel while in functions of
Record or Play. Examples of its use are: to prevent
recording of unwanted breaks in radio programs, to
noiselesslyholdback the tape for instantaneous starts
in either Record or Play, to precisely preset the re-
cord level while in the Record mode, and to moment-
arily stop tape in transcribing. The Instant Stop is
inoperative in functions of Rapid Forward and Rewind.
Record Lock Button
This buttonacts as a safety device and prevents
the Function knob from engaging the Record mode,
thus guardingrecordings from accidentaL erasure. To
make a recording the button must first be depressed
before the Functionknob can engage the Record mode.
The buttonis resetwhenever the Function knob returns
to the Stop position.
Speed Change Knob
Operation of this knob selects either 3 3/4 ips
or 7 l/2 ips tape speedswhiletherecorder is engaged

in any function. Rapid Forward winding can be accel-
erated by selecting thel l/2 ips tape speed. The
fidelity on7 t/2 ips selectionisgreaterinsofaras re-
cording and reproducing are concerned.
Record Level I ndicators
Series T-2000 Recorders - Withthe combination
ptay/"m in Series T-2000 re-
corders, the Record Level indicator (labeled 'Record
Level") isusedtogive a visual analysis of the correct
volume setting for the recording of monaural 2 (or
twin) - track tapes. The left or "Normal, half of the
indicator flashes to indicate a correct volume level,
and the right or "Distort" halfof the indicator flashes
when the volume level is too high. The proper re-
cordinglevelmaybepresetwith the recorder in either
the Stop or Record functions, If the volume level for
recording ispresetin the Stop position, the Tone con-
trol should be turned to "Treble." The Tone control
has no effect on the record level in the Record function.
Series T-2200 Recorders - Two Record Level
indicators are used in Series T-2200 recorders - one
is labeled "Upper ChannelRecord Level" andthe other
is labeled "LowerChannelRecord Level." The Upper
Channel Record Level indicator is the same indicator
that is used in the T-2000 Series. However, with the
separate stereo in-line head usedin the T-2200 Series,
the indicator is used to give a visual analysis of the
correct volume setting for the recording of:
1. Monaural 2 (or twin) - track tapes.
2. Monaural 4-track tapes.
3. Upper channel of stereo 2-track tapes.
4. Upper channel of stereo 4-track tapes.
The operation of the Upper Channel Record Level in-
dicator is thesameas that described above for Series
T-2000 recorders.
The Lower Channel Record Level indicator is
used to give a visual analysis of the correct volume
settingforthe recording of the lower channel on stereo
2-track and 4-track tapes. Thevolume control on the
external stereo amplifier should be adjusted so that the
"Normal" half of the indicator flashes, and no flashing
occurs at the "Distorted" half,
I ndex Counter
Set the counter to zero by turning its knob to-
ward the frontofthe recorder when starting to record
orplaybackareel oftape. Ifthe reading of the counter
is noted at various points in the tape travel, new pro-
gram selections can be indexed, or previously recorded
selections can be located with great accuracy.
Head Track Selector
( Series T-2200 Recorders 0nly)
The head track selector knob moves the head
assemblies up or down to properly orient the heads
for the monaural record/playback and stereo record./
playback operations. Refertothe "Operating Instruc-
tions", page 6.

Fig. 2. Rear Panel Connections
Automatic Feature of Tape Cutoff
This feature is controlled by a weighted pin which
moves into a siot in the cutoff post when the tape runs
out between the post and pin while in functions of Play
or Record. Movement of the pin into the cutoff post
opens the tape cutoff switch which interrupts power to
the recorder, andthusturns it Off. To turn on the re-
corder after automatic cutoff, the Function knob must
be turned to the Stop position. The tape can then be
rethreaded on the machine. Ifdesired, the tape cutoff
feature can be made inoperative by placing a piece of
tape over the slot in the cutoff post, The automatic end
of tape cutoff is inoperative in the Rewind and Rapid
Forward modes.
Rear Panel Connections ( See Fig. 2)
Input (Series T-2000 Recorders) - Thelnputjack
ln the@nnect theaudio
signals from a microphone, a phonograph, a radio, or
some other suitable source, to the recorder for the
purposeof makingmonauralrecordings of 2 (or twin) -
track tapes. Theproperinput circuit is automatically
selected by the different lengths of input plugs. The
shorter (1") plug is used with the microphone and a
I 3/16" plugis usedforthe radioor phono connections.
Input (Series T-2200 Recorders) -Two Input
jacks ders - one is
labeled "Upper Channel Input" andtheother is labeled
"Lower Channel Input. " The Upper Channel Input jack
is identicalto the Input jack that is used in the T-2000
serres. However, withthe separate stereo in-Iine head
usedinthe T-2200Series, thelnput jackis used to con-
nect the programmaterialtotherecorder for the pur-
pose of recording:
1. Monaural 2 (or twin) - track tapes.
2. Monaural 4-track tapes.
3. Upper channel of stereo 2-track tapes.
4. Upper channel of stereo 4-track tapes.
The Lower Channellnput jack is designed to op-
erate from a low-impedance output transformer (B to

16 ohms) of a radio, television, phonograph, auxiliary
amplifier, or any other stereo appliance. The Input
jack connects the program haterial to the recorder
for the purpose of recording the lower channel of stereo
2-track and 4-track tapes.
P.A.,/Monitor - Record Mike-This is a slide
switch@e speaker in either
the Stop (P.A.) or Record functions. With the switch
in the Record Mike position, the speaker is silenced
in functions of Record or Stop. With the switch in the
P. A.,/Monitor position, the speaker is connected so that
the recorder may be used as a public address system
in the Stop function, or so that the program material
can be monitored in the Record function. In Series
T-2000 recorders, the monaural recording of 2-track
tapes can be monitored. In Series T-2200 recorders,
both the monaural recording of 2-track and 4-track
tapes, and the stereo recording on the upper channel
of 2-track and 4-track tapes can be monitored. The
switch has no control ol the speaker in the Play func-
tion.
Extension Spea.ker - This jack is labeled "Exten-
sion Speaker" inSeries T-2000 recorders and "Upper
Channel Extension Speaker" inSeries T-2200 record-
ers. These jacks are identical, the only difference
being their application in the different recorders.
The jack provides a connection for an external
speaker or head phones. The nominal impedance of
theexternalspeakershouldbe 8 ohms, but speakers of
impedance ranging from 3.2 to 16 ohms may be used
withonlya slightloss of power. Accessories, such as
the TE-401 ear phones may alsobe used. The associa-
ted connecting plug of the external speaker: or phones
will automatically disconnect the speaker in the re-
corder. The external speaker duplicates the functions
of the interna-l speaker.
InSeries T-2000 recorders, the ExtensionSpeak-
er jack delivers the output from monaural 2-track
tapes. InSeries T-2200 recorders, the UpperChannel
htension Speaker jack delivers the output from mon-
aural 2-track and monaural 4-track tapes, and,/or the
upper channel output from stereo 2-track or 4-track
tapes,
Auxiliary Amplifier (Series T-2000 Recorders)-
This jackis used in conjunction with the Play function
of the recorder. In Series T-2000 recorders, the
Auxiliary Amplifier jack may be used to deliver the
preamplifiedoutputfrom monaural 2-track tapes to an
external Hi - Fi system for further amplification and
control.
Auxiliary Amplifier (Series T-2?00 Recorders) -
Two Auxiliary Amplifier jacks are used in Series T-
2200 recorders- one is labeled "Upper Channel" and
the other is labeled "Lower Channel". Both jacks may
be usedinconjunctionwith the Play function of the re-
corder. The Upper Channel jack is identical to the
Auxiliary Amplifier jack usedin the T-2000 Series.
However, withtheseparatestereo in-line head used in
the T-2200 Series, theupperchanneljack maybe used
to deliver the preamplified output from monaural 2-
track and monaural 4-track tapes, and/or the preamp-
lified output of the upper channel from stereo 2-track
or 4-tracktapesto an external Hi - Fi system for fur-
ther amplification and control.
The Lower Channel jack may be used to feed the
preamplified Iower channel output of stereo 2-track and
4-tracktapestoanexternal Hi - Fi system for further
amplification and control.
Aux. A.C. Outlet-This power outlet can be used
to control the power to any appliance (radio, televi-
sion, phonograph, etc.) thatdoesn't require more than
200 watts. Power to the outlet is controlled by the
automatic tape cutoff switch. Power is applied to the
outlet when the Function knob is in the Stop position,
or when the tape has been threaded on the machine for
use in functions of Record or PIay. Exa"mples of the
outlet's use are to turn off po\ryer to a radio tuner or
auxiliary Hi - Fi system at the end of the tape.
OPERATI NG I NSTRUCTI ONS

To Record or Play Stereo 2 - Track Tapes
( Series I-2200 Recorders 0nly)
Stereo 2-track tapes contain one full length re-
cordingonthedull side of the tape. To record or play
a stereo 2-track tape, proceed as follows:
1. To record from aradio, television, auxiliary
amplilier, or phonograph.
a. Turn the Function knob to the stop
position and thread the machine.
b. Turn the head track selector knob to
the "2-Track" position. This action
moves the heads in a position with re-
spect to the tape as shown in Fig. 6.
c. TurntheSpeedChange knob to the de-
sired tape speed.
d. Turn the recorder's Tone control to
"Treble" and set the slide switch at
the rearofthe recorder to the Record
Mike position.
e. Insert the input signals from the out-
putterminals (such as speaker term-
inals, output transformer terminals,
preampoutput jack, etc.) of the stereo
sound-producing appliance into their
respective input jacks at the rear of
the recorder. Theoutputfromtheleft
cha.nnel of the stereo appliance should
be connectedtothe Upper Channel In-
put jack. The output from the right
channel of the stereo appliance should
be connectedtothe Lower Channel In-
put jack.
f. Theinputsignalfedtothe Upper Chan-
nel Input jack is preamplified by the
recorder before it is recorded on the
tape. This being the case the signal
fed to the Upper Channel Input jack may
be of a signallevel as low as 2 milli-
volts.
The input signal fed to the Lower Chan-
nel Input jack is not preamplifi.ed by
the recorder before it i.s recorded on
the tape. Thisbeingthe case the sig-
nal fed to the Lower Charnel Input
jack must be preamplified to a signal
level oI at Ieast 1 volt by the external
stereo appliance. To also match the
input impedance of the Lower Channel
Input jack, theoutput impedance from
the right channel of the stereo appli-
anceshouldbewithin the range of 3 to
16 ohms.
g. Adjust volume control on left channel
of stereo appliance for normal listen-
ing level. Thereafter, adjusttheVol-
ume control on the recorder so that
the "Normal" halfof the Upper Chan-
nal Record Level indicator flashes,
and noflashingoccurs at the "Distor-
ted" half.
Adjust Volume control on right chan-
nel of stereo appliance so that the
"Normal" half of the Lower Channel
Record Level indicator flashes, and no
flashing occurs at the "Distorted" half.
h. Depress the Record Lock Button and
turn the Function knob to the Record
position. The recording will start.
Obs erve both Record Level indicators
again, and if necessary readjust the
proper Volume control for normal
flashing. Record the tape through in
one direction only.
2. To play a stereo recorded or prerecorded
2-track tape.
Fig. 7. "A" Position of Heads Shown for
Stereo 4-Track Record or Playback

a. With the Function knob in the Stop
position, placethe full reel of tape on
the left spindle and thread the machine.
b. PlacetheSpeed Changeknobto the de-
sired tape speed. Make sure that the
head track selector knob is turned to
the "2-Track" position. The "2-
Track" positionof the heads is shown
in Fig. 6.
c. Connect the Lower Channel Auxiliary
Amplifier jack at the rear of the re-
corder to an external amplifier and
speaker system. Placethespeakerat
least 7 feettothe rightofthe recorder.
d. Turn the Function knob to the Play
position and play the tape through in
one direction only.
e, The upper stereo channel or track is
played back through the tape recorder
and its self-contained speaker (left
speaker). The lower stereo channel
or track is played back through the
external amplifier and speaker system
(right speaker).
f. InaHi - Fi hook-up, itmaybedesired
to play back the upper stereo channel
through an auxiliary amplifier and
speaker system to more closely match
the playbackofthe lower stereo chan-
nel. To do this, connect an auxiliary
amplifier and speaker system to the
Upper Channel Auxiliary Amplifier
jack at the rear of the recorder. Set
the recorder's Tone control to "Hi -
Fi" position and adjust the recorder's
Volume control until the "Normal!'
half of the Upper Channel Record Lev-
el indicator flashes. Thereafter, ad-
just the Volume and Tone contlols on
the auxiliary amplifier for the desired
listeningpleasure. To silence the
speaker in the recorder, insert a plug
into the Upper Channel Extension
Speaker jack, For best stereo re-
production, the right and left speakers
should be identical units, of good qual-
ity, and at least 7 feet apart.
To Record or Play Stereo 4 -Track Tapes
t Series l-2200 Recorders Only)
Stereo 4-track tapes contain two full length re-
cordings (anupper andlowertrack for each recording)
on the dull side of the tape. The procedure for re-
cording and playing 4-track stereo is essentially the
same as for recording and playing 2-track stereo. To
record or play 4-track stereo, proceed as follows:
1. To record from a radio, television, auxiliary
amplifier, or phonograph.
a. Turn the Function knob to the Stop
position and thread the machine.
b. Turn the head track selector knob to
the 'A'r position. This action moves
the heads inaposition with respect to
the tape as shown in Fig. ?.
c. Follow the instructions as described
in Steps 1-c, 1-d, 1-e, 1-f, 1-9, and
1-h under "To Record or Play Stereo
2-Track Tapes.
d. At the end of the first full-length re-
cording, return the Function knob to
theStopposition. Takethefull reel of
tape from the right spindle, turn it
over, and place it on the left spindle.
Place empty take-up reel on right

Erasing Tape
Whenever a monaural or stereo recording is
made, any prerecorded material on the tape is auto-
matically erasedbeforethe new material is recorded.
Erasure is accomplished onlywhen the recorder is in
the Record function. In Series T-2000 recorders the
erase head erases approximately t/2 of the tape each
time the tape passes the head.
In Series T-2200 recorders, the upper-channel
section only of the erase head erases approximately
o
|-

ril
T
\Jl

r/4 ofthetape eacntimethe tape passes the head when
making monaural recordings. When making stereo re-
cordings in Series T-2200 recorders, both the upper-
channel section and the lower-channel section eaeh of
the erase head erases approximately l/4 of. the tape
eachtimethetapepasses the head. The lower-channel
section of the erase headis made operative only when
a pLugisinsertedintotheLower Channel Input jack for
the Record function.
NOTE: When making monaural recordings on
Series T-2200 recorders, make sure that
no plug is inserted into the Lower Chan-
nal Input jack. Inadvertent insertion of
a plug into this jack wiII automatically
erase any prerecorded material on the
lower channel.
To erase the tape without recording new sound,
turn the Volume control down and engage the Record
function.
Public Address System
The recorder may be used as a public address
system whentheStopfunctionis engaged. Set the slide
switch at the rear of the recorder to the P.A.,/Monitor
position and feed the signal from an external source
such as a microphone, radio, AM-FM tuner, phono-
graph, etc., into the jack labeled "Input" in Series T-
2000 recorders, orintothe jack labeled "Upper Chan-
nellnput" inSeries T-2200 recorders. TheToneCon-
trol is fully effectiveinthe P.A. function. When using
the microphone for P. A., keep the distance between the
microphone and speaker as far as possible to prevent
feedback and howling. For best results plug an external
auditorium speaker intothe Extension Speaker jack at
the rear of the recorder.

Check for binding in the following:
1. Flywheel (182) bearings. Check by moving
7 1/2 ips speed idler assembly (?0) or 3 3/4
ips speed idler assembly (172) - depending on
which speed is selected - and rapid forward
idler assembly (78) away from the flywheel;
rotate the capstan by hand. A slight drag is
normally obtained from take-up belt (147).
2. Right and left reelspindles. Thebrakes
should be disengaged or held away before the
spindles are turned.
3. Pressure roller (34) bearing.
4. All idler and drive wheel bearings.
5. Motor bearing. Check by turning shaft by
hand.
Check to see that:
1. Supply reel isfreetorotate and is not scrap-
ing against the top plate.
2. Brakes are completely released.
3. Pressure roller (34) is making good contact
with capstan.
4. Capstan and pressure roller are clean.
Check for irregularities in the following:
1. Idler wheel surfaces.
2. Pressure roller (34) surface.
3. Take-up tension. The take-up clutch is de-
signed to slip during normal operation to com-
pensateforthe difference in the rate of rota-
tion between a full and empty reel. Check by
holding the take-up spindle while the recorder
is in the Play function. The clutch action
should be smooth and nonpulsating. If the sur-
face of the take-up clutch (143) is gummy or
worn, it should be replaced.
Tape Squeal or Squeak
Tapesquealorsqueak is heard as a high pitched
sound that accompanies recording or playback. It can
be heard in quiet surroundings when listening close to
the sound head and with the Volume turned down.
Squeal or squeak can be minimized as follows:
1. Clean head (s), pressurepads, andtape guides
with alcohol.
2. Use a good and known name-brand tape. An
inferior brand of tape with insufficient lub-
rication may be helped by treating it with
silicone lubricant.
3. Replace pressure pads. Place thin telflon
film tape over pads if necessary.
4. Slightlydecrease the tension of pressure pad
springs (112 and 115).
Rewinds, But No Rapid Forward( Check Rapid
Forward With Nearly Full Take-Up Reel)
1. Check high speed slide arm (87) to see if it
moves approximately 7/8" to the right from
the neutral position. This should allow idler
assembly (?8) to be pulled by its spring (?3)
into contact with high speed drum (141) and
flywheel (182). A weak spring (73), binding
idler slide (77), or bent arm (?9) may pre-
vent this. AIso check for binding of other
mechanical linkages.
2. With tape speed selector in 7 L/2ips posi-
tion, idler slide (69) must be free to slide
7 t/2 ips speedidler assembly (70) into con-
tact with motor pulley (159). Check tension
on idler spring (68).
3. With tape speed selector in 3 3/4 ips posi-
tion, 3 3/4 ips speed idler assembly (L72)
should make contact with motor pulley (159).

icular check fol binding in the amplifier func-
ticn switch(M4). To check this, Ioosen set
screw (85) on switch actuating arm (83) and
slide upward on function shaft (52 ). There-
after, see if mechanism operates normally.
Binding in the amplifier function switch may
be causedbythe switch shield rubbing against
the switch slide. In some cases excessive
friction in the function switch can be reduced
by lubricatingtheswitch contacts with a non-
oxidizing lubricant.
2. If turning the Volume control to Off does not
trip the Functionknob to Stop position, check
to see that the roll pin at the bottom of the
Volume control knob is tripping function cam
pawl (3?).
Function KnobWill Not Stay in Playor Record Position
Spring (36) disconnectedorbroken. This spring
must be connected as shown in Fig. 16. If not, the
Function knob will return to Stopposition when placed
in the PIay or Record position.
Faulty lnstant Stop
With Function knob in the PIay position, actuate
the instant stop arm (44). Checkto see that upper in-
stantstopplate (132) comes in contact with the rubber
tire (153) onrewindspindle (152) the instant the pres-
sure roller (3a) starts moving away from the capstan.
Tape movement should stop. Upon releasing the in-
stant stop arm, tape should resume its normal travel.
If not, check to see that spring (135) is connected as
shownin Fig. 17 so that it returns the upper (132) and
lower (134) instant stop plate to their original positions,
thus disengagingthe upper instant stop plate (1 32) from
the spindle tire (153).
Tape Counter Sticks
Counter stickingis usually caused by a defective
counter (1?1) andnotbyslippage of tape-counter drive
belt (154). Check counter.
