About the automatic-tape-select function
This unit is equipped with the automatic-tape-select feature; it
automatically detects the type of tape being used, and then makes the suitable adjustments of the bias and equalization ac- cordingly.
About the Dolby noise-reduction system
The Dolbynoise-reductionsystemisdesignedto effectivelyredu- ce the annoying high-frequency "hissing" noise typical of cassette tapes. During recording,the system functions to in- crease the high-frequencysound level,the sound,andthen,dur- ing playback,that same portionis weakenedto bringit backto the previouslevel.
Thisunit includestwo typesof Dolby noise-reductionsystems, the DolbyB NR-typeand C NR-type.
Dolby B.type noise.reduction
Noise is reduced to about one-third. Use this system when playing back tapes recorded by the Dolby- B noise-reduction system, such as prerecorded music tapes, etc.
Dolby C-type noise-reduction
Noise isreducedto about one-tenth. Usethissystemforthe recordingandplaybackofsoundsources that have a widedynamic rangeand good tonequality,such as FM broadcastsof live performances,etc., and for playingback suchtapes.
About the Dolby HX-Pro headroom
extension system
Byfunctioningto Improve the maximum outputlevelofthetape's high-frequencyrange, thissystem permits recordingswithouta reduction in the level of the sound source's high-frequency range. In addition,by usingthe systemin parallelwiththis unit's noise-reductionsystem,recordingandplaybackwitha greatlyex- tendeddynamicrangeis possible.

About the selection of the Dolby NR type
The Dolby NR effect can be obtained by using the same type of Dolby NR during both recording and playback: Refer to the follow- ing table when selecting the type (either B or C).
Type B
TypeC
Use this type when the deck on which the tape will be played back is equipped with only type B
Dolby NR. Use this type when the deck on which the tape
will be played back is equipped with type C
Dolby NR. (for example, when this unit isalso go-
ing to be used to play back the tape.)
Refer to "About the Dolby noise-reduction system" on page 8
About the recording level adjustment
If the recording level Is too high, there will be distortion in the recorded sounds, and if it is too low, the hiss noise inherent to recording tapes will become noticeable. In order to make high-quality recordings, use the REC LEVEL con-
trol to adjust so that highest values of the input level indicated by the level meter do not exceed the standard recording level (the
number indicated in parentheses) for the tape being used.

they are on the tape being played back.
• Because the signal being recorded from Deck 1 onto Deck 2
does not pass through the receiver, it is possible to change the
setting of the receiver's input selector during recording in order
to listen to some other sound source.
J,
When recording with the recording speed set to double speed,
noise interference may be recorded onto the tape if there is a television set nearby, so make the recording in a location separated from the television set or switch off the television set during recording.

Selection o£ cassette tapes
Cassette tapes exceeding 90 minutes
These tapes are handy for their long playback and recording time but be careful about repeatedly stopping and starting, rewinding and fast forwarding these tapes in short intervals as they are thin, tend to stretch and may become entangled in the machine.
Fe.Cr tapes (tYPE Ul) The high frequency range will be emphasized, and it will not be possible to obtain a flat frequency response.
Metal tape without detection holes in the cassette Recordings will be very distorted. (However, there will be no pro-
blem with playback.)

Head demagnetization
In order to maintain good sound quality during recording and playback, it is recommended that the head assembly be demagnetized if distortion or poor sound quality persists after cleaning the heads. If the head assembly becomes magnetized, it could create noise in the recordings, loss of high-frequency response or erasure of valuable recordings.
Several types of head demagnetizers are available and may be purchased separately at local electronics supply stores.
Follow the instructions that are supplied with the device.
Do not bring any type of metal objects or tools such as magnetic
screwdrivers in contact with the head assembly.
Main tenance of external surfaces
To clean this unit, use a soft, dry cloth. If the surfaces are extremely dirty, use a soft cloth, dipped into a
soap-and-water solution or a weak detergent solution. Wring the cloth well before wiping the unit. Wipe once again with a soft, dry cloth. Never use alcohol, paint thinner, benzine, nor a chemically treated cloth to clean this unit. Such chemicals may damage the finish of your unit.
