Making Good Sounding Recordings
Dolby Noise Reduction Systems
Dolby B NR is the system used in most cassette tape decks to re-
duce the background noise that is inherent in all cassette tapes.
Dolby Laboratories then developed an even more effective noise
reduction system, Dolby C NR, in response to the demand for in-
creasingly better sound quality from cassette tapes.
Both Dolby noise reduction systems operate by boosting sig-
nals during recording that fall below a certain input level. Dolby
B and C NR operate on the higher portions of the frequency spec-
trum using what is called a ‘‘sliding band”’ technique. This is be-
Using the Accubias Control Knob
Although this deck is equipped with an Accubias system for fine
bias adjustment, you will get excellent results with most tapes by
just leaving the ACCUBIAS knob in the center clickstop position.
Nevertheless, some tapes may require additional bias adjustment
in order to obtain flat frequency response. In such cases, refer to
the following diagram. For tapes not listed, refer to the ‘‘Deter-
mining the Conrect Accubias Setting for Tapes Not Listed”’ sec-
tion at right.
cause tape hiss is most prominent during the quiet, high frequency nr rine
portions of a recording. These same signals are then reduced back TORR
to their original strength during playback, thereby reducing the m sh |
background noise by the same amount. In order to operate only Bone ace snes!

The Dolby HX Pro System
Tape sensitivity is constantly changing as recordings are made
due to the biasing effect of high frequency audio signals. Dolby
HX Pro is a system that compensates for these undesirable fluctua-
tions during recording. It does not operate during playback, so cas-
settes recorded with Dolby HX Pro can be played back on decks
not equipped with the system.
Note:
Dolby HX Pro operates independently of Dolby B and C NR, and
only during recording.
Determining the Correct Accubias Setting for Tapes Not
Listed
Use the following procedure to determine the correct Accubias
setting for cassettes not listed in the above diagram. As it is neces-
sary to make use of the ‘‘white noise’’ produced by FM tuners
when tuned to the unused frequencies between stations, it is not
possible to perform this procedure with FM tuners that do not pro-
duce white noise. In such cases, use the center clickstop position
when making recordings.
(1) Set your FM tuner to an unused frequency between stations.
Setting the Proper Recording Level
The recording level has an important effect on the sound quality a
tape will have when it is played back. A recording level that is too
high will cause distortion while one that is too low will lower the
signal-to-noise ratio resulting in a tape with excessive ‘‘hiss
noise.’’ It is particularly important to set the recording level cor-
rectly with cassette tapes since they have a much thinner magnetic
coating than open reel tapes. The thin coating gives the tape a
comparatively low saturation level which can easily be surpassed
if the recording level is set too high.
The recording level indicators feature a peak-hold function for the
indicators from -6 dB through +8 dB. This can come in handy
when setting the recording level.
CD Synchro Recording System
(2) Turn the tuner’s FM muting switch off. (White noise should
be audible.)
(3) Record white noise on a section of the cassette tape you wish
to use at about the -10dB recording level. (The ACCUBIAS
knob should be set to the center position.)
(4) Compare the sound of the tuner’s white noise with that re-
corded on the tape. If they sound the same, the Accubias set-
ting is correct.
(5) If they do not sound the same on the first try, turn the
ACCUBIAS knob toward the (+) or the (—) indication and re-
peat the above procedure. When you have found the position
that most closely approximates the sound of the FM tuner’s
white noise, record the setting in the above diagram for future
reference.
Once the TA-6510 is connected to a CD player bearing the RI mark (see page 4.), pressing the » button of the CD player will cause re-
cording to commence automatically on the TA-6510.
1. Insert a cassette with the side to be recorded facing out.
2. Start the CD player.
