=GENERAL INFORMATION
Revere Models T-1100, T-1120, andTR-1200 Tape Recorders feature a single three position
functionknob which performs the electrical and mechanical functions for "Record", "Stop", and
'-'Play"operations. Allthreerrnits basically incorporate the same tape transport mechanism but
differ slightly in amplifier circuitry and component values. The existing ditferences are best
pointedoutin the schematic diagrams, exploded views, and mechanical & electrical parts lists.
The Model TR-1200 is the same as Model T-1100 except for the addition of the Bfgg-6 Radio
Tuner Sub-Assembly. Model T-1120 is the same as Model T-1100 except for a built-in stereo-
phonic head and preamplifier (El199-11) for the lower channel. Treatment of the subject matter
pertainto the machines as being used a"s a monaural unit and information given for Model T-1I00
will cover Models T-1120 & TR-1200 unless noted otherwise.
These units are designedto recordtwotracks of material on standard width recording tape ,
which doubles the playing time of a tape reel with no loss of frequency response of quality. Re-
cordings may be made from microphone, phonograph, AM-FM tuner, Hi:Fi systems, external
radioortelevision, in additiontothosemadedirectly from the self-coniained "adio used in Mode1
TR-1200.
CAUTION: Do not use on direct current. Check name plate at rear of recorder for proper
current and voltage.

FUNCTIONS OF CONTROLS,
(Refer to Figure 1.)
0n-Off-Volume Control
Initial clockwise rotation of this control supplies
power to the entire recorder; further rotation regulates
thevolume for both the recording and play-back oper-
ations.
Tone Control
This control is designed to give three distinct
tonal extremes, and can be varied continuously between
them to produce a blend of tone suitable to any type of
program. The tone control is automatically discon-
nected when recording.
Function Knob
AIt electrical and mechanical functions for
"PIay" and "Record" operations are performed by this
single three position knob. AIso, for convenience and
protection, the Function Knob is returned to "Stop"
position when the power On-Off-Switch is turned of{
thus disengaging all pressure pads and rubber idlers.
I ND ICATORS & SW ITCHES
Speed Change Knob
Operation of this knob selects either 3 3/4 ips,
(slow speed, "S"), or 7 1/2 ips, (fast speed,"F'), tape
speeds while the recorder is in any function. The fi-
delity on 7 t/2 ips selection is greater insofar as re-
cording-reproduction is concerned.
Automatic Record Lock Button
This is a safety device preventing the Function
Knob to be turned to "Record" position, thus guarding
recordings from accidental erasure. The Lock Button
is re-set whenever the Function Knob returns to the
"Stop" position. To make a recording, the Record Lock
Button must be depressed before Function Knob can be
turned to "Record" position.
Rapid - Forward Rewind Lever
This lever is used to skip ahead to any point on
the tape or to rewind tape onto the supply reel. By
moving this lever back & forth the tape can be inched
along in either direction to find an exact point on the
tape. This levercan bemovedwhile the Function Knob
"n
o
rJ

Figure 3.
is in either "Record" or "Play", and the lever will
automatically return the Function Knob to "Stop".
Manual Start-Stop Button
This button is provided to instanily stop the tape
in either "Record" or "PIay, functions. Examples of
its use are: to prevent recording of unwanted breaks
in radio programs; to noiselessly hold back the tape
for instantaneous starts in either "Record" or "play"
functions; to precisely pre-set the record level while
the Function Knob is in "Record" position; to momen-
tarily stop tape in transcribing.
Record Level lndicator
This indicatortakes the guessworkout of setting
the recording level. The volumecontrol should bead-
justed until the "Normal" half of the indicator flashes
and no flashing occurs at the "Distorted" half. If it is
desired to preset the level in "Stop" position, turn the
tone control to treble.
lndex Counter
This is a precision revolution Counter enabling
Page 4
pinpointing of selections. The Counter is re-set by
turning the Counter wheel back.
Dual Hi-Lo lnput Jack
I The Input Jack is designed to make the proper
selection between the low level microphone (requires
short input plug 15n6" Iong) or high levelradio-phono
connection (requires long input plug, I g/!6,, long),
thus making two input jacks unnecessary. When the
longer input plug (three circuit) is used, the speaker
is automaticallyconnected for monitoring in "Record"
position or for public address in "Stop" position. When
the shorter plug is used, the speaker is left discon-
nected. Regardless of which input plug is used, in
both cases the buitt-in radio used in Model TR-1200
is disconnected.
Output Jack
Located on the rear panel,this jack can be used
to connect accessories such as a remote speaker (3.Zf,}),
or earphones. The Attachment Cord can be used'for
this purpose. See Auxiliary parts List page 24 for
l-isting of accessory parts. The speaker in the recorder
is automatically disconnected whenever a plug is in-
serted in the Output Jack.

Threading The Tape
1. Plug linecord in socket provided at the rear
of recorder, and plug the linecord plug into a conven-
ient wall receptacle of the proper rating as specified
on name plate.
2. PlacefuII supplyof tape (glossy side out,i.e.
"A" wind) on left spindle and empty reel on right spind-
le, making sure the reels are fully seated.
3. Unwindabout 14" of tape from the supply reel.
Hold a section of the tape straight with both hands and
insert the tape in the tape slot making sure the dull
coated side of the tape faces the rear of the recorder.
Feed the end of th'e tape into one of the radial slots in
the empty reel. Rotate the reelcounterclockwiseuntil
the tape is secured and aII slack is taken up between
reeIs.
To Record From Microphone
Note: The Revere automatic high frequency erase re-
moves previous recorded sound when new ma-
terial is recorded; therefore, no special step is
necessary to erase recordings before new re-
cordings are made. The Erase functions only
when the Function Knob is in "Record". By
turning the volume control down, the recorder
will erase withoutputting new soundon the tape.
1. Insert microphone plug firmly into input jack.
2. Turn tonecontrol to treble, and while talking
into the microphone adjust the volume control until
"Normal" half of indicator flashes and no flashing
occurs at the "Distorted" half.
3. Set the index Counter to zero. While holding
the Record Lock Button in its depressed position, turn
the Function Knob to "Record" position.
To Record From Radiq TV, 0r Phonograph
l. To Record From Radio or T.V. - Insert
Attachment Cord plug into the input jack on the re-
corder. Connect the cord clips to the radio or T.V.
speaker terminals. Proceed with recording as des-
cribed, in "To Record From Microphone".
2. To Record From Phonograph -Insert stand-
ard phono plug, used with most crystal or magnetic
type phonographs, into input jack onrecorder. If stand-
ard phono plug is not used, Attachment Cord may be
used. Proceed with recording as described in "To
Record From Microphone".
Monitoring Recordings
The longer L-3/t6" standard phone plug, when
inserted in the input, turns on the recorder speaker
for monitoring radiq T.V, or phono. Tomonitormike
recordings, a high impedance headset can be plugged
into the output jack. Monitoring mike recordings from
the recorder's speaker can be accomplished by using
the microphone P.A. extension cord accessory. (See
Auxiliary Parts List). With this cord, the speaker is
connected for Public Address in "Stop" position and
Speaker Monitoring in "Record" position.

To 0perate Radio-Recorder Combi nation
(Model TR-1200)
1. To Listen To Buitt-In Radio - Any plugmust
be removed from recorder's input jack. Turn Function
Knob to "Stop" position, and adjust tone & volume
controls to desired levels. To disconnect Radio, while
in "Stop" position, any plug can be inserted into the
input jack or the Radio can be de -tuned.
2. To Record From Built-In Radio - Any plug
must be removed from the input jack. No external
connections are necessary. Proceed with recording
as described in "To Record From Microphone".
3. Whenexternal sources of recording material
are used, the built-in radio wiII be automatically dis-
connected by the insertion of the respective plug into
the input jack.
Twin-Track Recording
1. These recorders are designed so that each
reel of tape holds two full length recordings, one on
each half of the duII'.side of the tape.
2. After the first track has been recorded, a
second recording can be made on the same side of the
tape by removing the reels from the recorder, turning
them over, and placing them on opposite spindles.
3. Thread the tape and proceedwith the record-
ing as previously described.
4. After the second track has been recorded,
the first track is ready to be played, withoutrewindirig,
by changing reels as described in Step No. 2 above.
Page 6
Splicing & Editing
Note: Since it is impossible to editandsplice one track
without affecting the other, recordings which
are to be edited should be limited to one track
only.
1. The tape may be edited by cutting out un-
wanted portions, or by joining selections into another
sequence. Announcements may be inserted between
selections, etc., and unused sections of tape can be
spliced together for re-use.
2. For bestresults,cut tape ata slightdiagona!
join ends together with splicing tape on the glossy side,
and trim off any excess width. Use Scotch #41 tape to
prevent bleeding of adhesive.
3. For very precise editing turn Function Knob
to "Play" position and push in Instant StopButton. Turn
.reels by hand tolocate a single word or sound. Cutor
mark tape at this sound by removing the head covers
and marking tape at the right hand pole face of the
Sound Head.
To Rewind Tape
1. The tape may be rewound at any time by
moving high speed lever (105) to the left. In so doing,
the tapeon the take-upreel istransferred tothesupply
reel.
2. By moving the high speed lever back & forth
(betweenrewind & neutral) the tapecan be inchedalong
to the number previouslynoted on the index counter.
3. After reaching the desired portion of the tape,
move the high speed lever to the middle or neutral
position to stop all movement of the tape.

ffi
To Play Back Recordings
1. Move high speed lever (105) to the left and
wind tape back to the original counter setting. Return
high speed lever to the center position to stop the reels.
2. Turnthe Function Knohto "Play"positionand
adjust volume and tone controls to the desired listening
leveI.
Fast Forward
1. Any portion of a recording may be skipped,
or any selection may be located in a few seconds by
moving the high speed lever (105) to the right. A few
seconds of "Fast Forward" is equivalent to several
minutes of playing time.
2. By moving lever (105) back & forth, the tape
can be inched along to an exact point.
3. After reaching the desiredportionof the tape,
move the high speed lever to the middle or neutral
position to stop all tape movement.
Connecting To Hi-Fi Systems
1. The recorder can beconnected toHi-Fi sys-
Figure 6.
TIPS ON RECORD ING WITH A MICROPHONE
tems by using Revere Hi-Fi cables (see Auxiliary
Parts List).
2. To connect for recording, plug a Hi-Ficable
between tfie recorder's input jack and the jack of an
amplifier marked "Detector", "Tape", "Recorder In-
put", or "Pre-Amp Output".
3. To connect for playing a tape, plug a Hi-Fi
cable between the recorder's rear output jack and
the jack of an amplifier marked "Auxiliary", "T\I',
"Tunert', or "lV Inputt'.
4. While tape is playing set the recorder's tone
control so that the black dot on the top plate assembly
is opposite the blank space between treble and bass;
set the volume control to flash the normal half of the
indicator. Thereafter, adjust the Hi-Fi amplifier
volume & tone to desired listening level.
To Use As Public Address System
1. Insert microphone plug into the Microphone
P.A. Extension Cord. PIug Extension Cord into the
recorder's input jack.
2. Turn Function Knob to "Stop" position and
adjust volume & tone controls to desired listening level.

In recording, the most satisfactory results are
obtained when the microphone is held about one foot
from the mouth. The microphone should notbe placed
on the same table with the recorder, or on a piano or
radio,as it may pick upvibrationsand producea noisy
recording. The pre-setting of the record level with
either microphone or radio will be more accurately
set if the tone control is placed in treble. In monitoring
with the recorder's speaker, the microphone must be
kept as farfrom the speakeras possible. Bestresults
wiII be obtained if the speaker and microphone are in
separate rooms. Feedback and howling will occur if
this precaution is not taken.

PREL IM I NARY TESTS
TEST PROCEDURE: FAILURE TO PASS ANY OF
THESE TESTS IND ICATES A FAULT THAT SHOULD BE
REMED IED .
1. Remove front and rear plastic head covers
(3 & 4) by pulling "up". Clean head (94), tape guides,
and capstan with alcohol.
2. Turn Function Knob (15) to "Stop" position,
place high speed lever (105) in the middle or neutral
position, and turn power "on".
3. Thread tape on recorder. Brakes should be
engaged. Pull required on reel should not distort the
tape and shouldoffer sufficient drag to preventspilling
of tape. Drop tape into threading slot. Attach free
end to take-up reel (right). Reel should rotate freely
counterclockwise and drag when rotated clockwise.
4. Turn Function Knob to "PIay" position.. Felt
pressure pads should press square against tape and
cover shinypole face areaunder tape. Pressure roller

ward) or left (Rewind) andcheck to see that the Function
Knob is automatically returned to "Stop" position;
without removing the recorder from its case by re-
moving six Phillips head screws from the case bottom
grille.
REPA I R PROCEDURE
pressure roller and pressure pads should also be re-
leased. Tape should move in either direction at a
greatly increased speed.
6. Returnhighspeed lever tothe middle orneu-
tral position. Tape should stop without spilling or
breaking.
7. Connect microphone and prepare to make a
