With a minimum of care and attention, your new TEAC 2300S will pr

2、ovide you with many years of recording pleasure. It was designed for your convenience and contains the latest technological improvements for enhancing the art of tape recording and listening. We know that you are eager to begin using your new deck. Before you start, however, we would encourage you t

3、o carefully read this Instruction Manual. We feel that the time devoted to this manual by you will be returned in increased enjoyment of your new TEAC 2300S. OPERATIONAL LIMITATIONS The TEAC 2300S is very well constructed, and adaptable to a wide range of condi- tions. It is still an electronic devi

4、ce with limits to be considered. To prolong the life of your new deck, consider the following factors when you install and operate. Mounting position This deck may be used in either the upright or horizontal positions. The upright position is preferred from the point of more efficient ventilation. L

5、ocations of constant high temperatures Do not operate this unit near heating appliances or on top of an amplifier where amplifier heat would contribute to a rise in temperature. Do not place the unit where it will be exposed to direct summer sunlight. Temperature extremes will not only cause degrada

6、tion of sound quality, but will also shorten the useful operating life of the unit. Avoid temperatures higher than I 00F. Locations of extreme low temperature In low temperature locations, lubricants will harden and satisfactory operation cannot be expected. Operation will be sluggish and an overloa

7、d may be placed on the drive motors. Avoid temperatures lower than 40 F. Locations of high humidity High humidity locations will shorten equipment life from corrosion and possible fungus growth on printed circuit boards. Dusty environments Your TEAC deck is a precision machine and as such should be

8、protected from dust. Operation in a dusty atmosphere will result in excessive bearing and tape head wear. Your tapes should also be kept dust-free. Fluctuation of the supply voltage Should you be in an area where line voltage fluctuation is severe, the use of a voltage controller may be advisable. *

17、lrequirements demanded by the semi-professionals and experienced audio enthusiasts. This manual, therefore, has been written in two sections. The forward section is rather brief and designed to familiarize you with the location of the features and controls, followed by a very brief, simplified, Basi

18、c Operations chapter. This first portion may not be sufficient for those without extensive recording knowledge and experience. The remainder of this manual expands the basic information to lead the novice into the exciting world of audio recording. There have been dozens of books and thousands of ma

19、gazine articles written about stereophonic audio equipment and techniques. It would be impossible to include all this published material in the space available to this Instruction Manual. Every instal- lation, every combination of components, and every situation has its own problems, with specific s

20、olutions required. Therefore, we recommend that if you are unable to achieve the results you want with your stereo system, talk with your dealer. If he is unable to solve your problem or give you a solution, perhaps he can refer you to a good book or guide you to some of the excellent magazine artic

21、les available. Your city library probably has many excellent publications to aid you to truly enjoy the wonderful world of sound recording.

Once the level has been set, select the TAPE Monitor position and adjust the OUTPUT Level Controls to obtain the same reading. Alternate betwe

PAUSE Control button operation Recording is greatly simplified by using the PAUSE button rather than the STOP button when you wish to temporarily halt the tape transport. The PAUSE mode is

35、 engaged by de- pressing the PAUSE button while recording to keep the decks recording circuits engaged. Recording is instantly restored by merely pushing thelI Play button. Use the PAUSE button 1. to eliminate commercials when recording from the radio; 2. to eliminate interruptions in the recording

36、during live recording or those caused by changing phonograph discs; 3. for keeping switch noises or needle clicks out of the re- cording; 4. anytime you wish to momentarily stop recording. If the STOP button is used rather than the PAUSE button, you must depress both the REC and the I., I Play butto

37、ns to resume recording. This increases the possibility of forgetting to depress the REC button which would pro- duce a blank section on the tape. The RECORD-PAUSE Mode is very convenient for setting the Recording Level, for you can set the MIC and/or LINE Input Controls to the desired VU Meter readi

38、ng without .actually recording .onto the tape. This eliminates having to rewind the tape aftr setting the recording levels as instruct- ed in the BASIC RECORDING PROCEDURES Section. During tape playback, the PAUSE button functions only to stop the transport in the same manner as the STOP button. -11

39、 - Level Setting Recording procedures have been greatly simplified over the years to the point where todays tape recorders can be operated by almost everyone. Perfect recordings are also much easier to achieve than before, thanks to improved tapes and advanced electronics. One area, however will al-

40、 ways make the difference between an excellent recording and an average recording: that is the skillful setting of the Level Controls. Correct level setting of the MIC and LINE Input Controls will assure full frequency response, maximum dynamic range, minimum amount of tape noise and the least possi

41、ble distortion in your recorded tape. This is based upon the nature of magnetic recording tape which has a useable re- cording range as shown in the chart below. Useable Range Saturation +6 VU -+-1- +3 vu -+-l- 0 vu -+-l- -+-+-20 vu -+-1- -1-40 vu -I- -50 vu -l- :fi-iJJii/J11 Noise Conventional Tape

42、 Low Noise/High Output Tape Useable Range When the input level (an audio signal of a specified voltage) is very low or weak, it must compete with the hiss and noise always present at the same low level on the tape. Stronger input levels are recorded above this tape noise and tend to cover or mask it

43、 so you hear only the desired sound during playback. If the input level is too high, it en- ters the region shown at the top of the chart, which re- presents the limits of the tape. This limit says that no matter how much stronger you record, the tape cannot accept and return the same strength of si

44、gnal. The result is known as saturation distortion, and is heard as a garbled or harsh sound. The dynamic range available is found between this distortion at the high end and the noise at the low end. As the chart also shows, there is a difference between recording tape. The tape on the left is repr

45、esentative of conventional or no.rmal recording tape. To the right is the improved kind of low noise/high output tape. Input Level Controls (MIC and LINE) are used to match the strength of the input signal to the requirements of the tape. If the input signal is a little too strong, these controls mu

46、st be adjusted to reduce it to prevent distortion. If the signal is a little too weak, the controls must be set to in- crease the preamplification for raising the signal above the tapes noise level. Of these two limits, the distortion caused by high level inputs is used as a reference for setting the controls. Generally speaking, the shaded area at the upper (right side) of the VU meters scal
