24. Capstan Drives the tape at a constant speed in the Play or Record modes. Not engaged with the Pinch Roller during Forward or Rewind modes, but rotation continues until electrical power is removed from the transport
25. NORMAL/SIMUL-SYNC switches In the NORMAL position, the TAPE: monitor function is performed by the Playback head in the SIMUL-SYNC position, that function is switched to the Record head to permit synchronization with the material being recorded on another channel. Always use the NORMAL position during regular Playback operation
26. Head Housing Protects the heads and SIMUL SYNC switches from dust and damage
27. GND connection For connecting a grounding wire between components or to earth ground if necessary to eliminate electrical harm
28. FUSE holder Contains a 2 amp fuse for overload protection

30. REMOTE CONTROL RC-120/TIMER CONTROL RC-320 Dummy Plug Unless one of the two optional accessories is connected here, this Dummy Plug must be inserted to permit proper operation of the tape transport
31. 3D OUTPUT jacks Connect to the Discrete inputs of  4-channel amplifiers or two 2-channel amplifiers. Notice that the channel designation corresponds with the VU Meters and Level Controls when viewed from the front of the deck
32. LINE IN jacks Line inputs for recording are connected to these pin cord jacks.

Basic Connection and Speaker Placement

If you wish to use the 3340S as a conventional, 2-channel stereo tape deck, use the FRONT connections only (Ll & R3). Remember to place the PLAY switch on the front of the deck in the 2CHAN position and leave it there.

Basic Operation of the TEAC 3340S

Transport Controls

Certain operations ace basic to tape deck operation and are referred to throughout this manual in a few words when they actually involve a certain level of familiarity with the tape transport operation. Connect only the AC power cord and use a reel of blank (unrecorded) tape and an empty reel.

1. Loosen the reel shaft tip fully CCW(counter-clockwise).
2. Align the outer 3 index tabs (Ref.2) and the inner index tabs (Ref. 3). This is done by turning the upper tab section (Ref. 2) slightly CCW to place the tabs in a straight line between the two sections.
3. Using both hands, grasp a reel and place its center hole partially over the reel shaft tip (Ref. 1). Then gently rotate the reel CCW while sliding the reel fully onto the turntable. When the outer 3 index tabs (Ref. 2) are fully visible above the reel, you may proceed to step (4).
4. Carefully rotate the outer tab section (Ref. 2) clockwise until it stops (approximately 60 degrees or 1/6 of a revolution). Then turn the reel shaft tip clockwise approximately 3 revolutions so it is finger-tip tight. The outer index tabs must be about mid-way between the corresponding slots on the reel.

NOTE: The tape must leave the left side of the full reel.

If large-center (NAB 10-1/2″) metal reels are to be used, insert the plastic Reel Adapters into the center of the metal reels before placing them on the reel tables. Also, place the Reel Heights Adapter sheets onto the Reel Tables. These inserts and sheets are included with the Standard Accessories packet accompanying your deck. Always use a reel of the same type and size on the right, take-up reel table. Both reels should be of the same hub diameter, material, and outside diameter to ensure proper braking and tension.

Playback Operation

Preliminary Settings

• Thread the tape.
• Confirm all Simul-Sync switches in the NORMAL position.
• Reset the Index Counter for “0000”.
• Set the following switches as indicated:
• REEL Size Selector switch to match the reels.
• SPEED Selector switch to match the speed used when the tape was recorded.
• All Level controls (OUTPUT, MIC, LINE) to MIN. (counter-clockwise).
• All OUTPUT Selector switches for TAPE monitoring.
• PLAY switch for 4CHAN operation.
• RECORD – EQ and BIAS switches have no effect during playback. g. RECORD – MODE switches all OFF.
• Verify the correct connections between all components.
• Prepare the 4-channel amplifier or integrated receiver for Discrete + Channel playback according to its manual of instructions.

1. Depress the POWER switch to ON.
2. Rotate the right-side reel clockwise by hand to remove the slack (looseness) from the tape, raising the Shut-off Arm.
3. Depress the play button for Playback to begin.
4. Adjust the OUTPUT Level Controls individually for each channel while observing the related VU Level Meter. The loudest passages of music should reach but not exceed a 0 VU indication.
5. Control the listening level with the Volume Controls on your 4-channel Stereo Amplifier.
6. After completing all audio adjustments on the deck and the amplifier (tone, balance, filter. eic.), you may rewind the tape to “0000” and listen again from the beginning.

Special Recording Information and Procedures

Recording with Microphones

Live Recording

High Quality recordings begin with high quality microphones. The TEAC 3340S will perform excellent live recordings from any high quality microphones (such as TEAC’s MC-201) with impedances from 600 to 10,000 ohms. Low impedance microphone of 150-600 ohms will also work satisfactorily.

1. Connect the microphones to the MIC Input jacks on the front panel.
2. Use headphones for monitoring to prevent feedback from developing whistles or squeaks in the recording.
3. Select OUTPUT – SOURCE.
4. Reduce the LINE Level control to MIN.
5. Adjust the MIC Level control for the proper recording level on the VU Meters.
6. Other recording procedures are the same as Recording Procedures.
7. Use the PAUSE control during interruptions in the recording.

MIC/LINE mixing

You may add your commentary to a musical recording, add music background to a live recording, and perform many other interesting recordings by combining the procedures for Live Recording with Microphones and the standard recording procedures for Line Inputs. Connect the microphones to the MIC Jacks on the front of the deck. Consider these following points while recording.

1. The use of headphones is recommended to prevent feedback squeals and whistles.
2. Use the SOURCE selection of the OUTPUT switches to simplify the synchronization of the MIC and LINE Inputs.
3. Adjust the MIC and the LINE Level Controls to balance the relative levels between the separate inputs while keeping the total input level within the limitations indicated by the VU Meters.
4. If the Line Input is Dolby-encoded, please note that the MIC Input will not be Dolbyized, thus it will sound unnatural during playback.
