@ REC LEVEL controls
Used to adjust the input level of the signal coming from
the rear panel LINE IN/REC jacks for recording, and the
adjustable signal level is displayed on the PEAK level
The White plug on the paired connecting cables
corresponds to the Left channel and the Red plug
corresponds to the Right channel. The LINE OUT/PLAY
jacks on the K-540 should be connected to the Tape PB
(Playback/Input) jacks on your amplifier, and the LINE
IN/REC jacks on the K-540 should be connected to the
Rec Qut (Rec/Output) jacks on your amplifier. Make sure
that the left and right channel connections are properly
made, and that the plugs are inserted firmly,
7 Amplifier or receiver
Connect the power cord to an AC outlet or to the AC
outlet provided on the rear panel of your receiver,
integrated amplifier, or control amplifier, etc. Make sure
that power to both the K-540 and your amplifier {receiver,
etc.) are turned off before making connections. With the
REMOTE CONTROL terminal on the rear of the K-540,
system remote control through the amplifier is possible.
Connect the terminal to the amplifier with the flat cable
supplied to the amplifier. For details of operation, refer to
the Owner's Manual of the amplifier.
There are many different types of cassette tapes available,
however, they all conform to standard specifications so
any brand may be used with the K-540.
e (Classification of Cassettes Tapes by Formulation
Cassette tapes are available in four basic types
depending on their formuiation, or type of magnetic
material and manufacturing process. These four types
are commonly known as Normal (I{NORM), Chrome
(I1/CrO2), Ferrichrome (FeCr), and Metal (1V/Metal), and
they each require specific bias, level, and equalization
settings for optimum performance. |
The K-540 has an Auto Tape Selector which
automatically adjusts for the proper bias, level and
equalization according to the tape formulation - all you
have to do is load a cassette and the Auto Tape
Selector does the rest.
e Old-type Metal tape cassette shells do not have the
necessary hole for Auto Tape Selector operation. It is
‘recommended that you do not record with this kind of
Metal cassette. However, Metal tape cassettes
recorded on another deck may be played back with the
K-540 at the Chrome (l{/CrQ,} settings. All current
cassette tapes will have this small opening in the
cassette shell, so be sure you use suitable cassettes
with the K-540.
* The K-540 does not have the required setting for
Ferrichrome (FeCr) tape, since this tape formulation is
not widely used. Should you use a Ferrichrome tape, it
will be recorded and played back at the Normal
(I/NORM) settings. And this will result in an unnatural
high frequency emphasis. This effect may be
compensated for somewhat by adjusting the tone
controls of your amplifier. _
e YAMAHA does not recommend the use of C-120
cassettes since the
extreme thinness of the tape makes them susceptible
to mechanical and electrical problems.
All cassette tapes are provided with erasure protection
holes to prevent recorded tapes from being accidentally
erased. There is a small tab covering the hole on each
cassette, and it should be broken off with the screwdriver
after recording a tape. Without this tab covering the hole,
it is impossible to record on that tape again; thus, you can
keep any recorded tape for as long as you wish without
fear of accidental erasure. Should you wish to use a
cassette tape protected in this way for later recording,
simply covering the hole with adhesive tape will permit
erasure and re-recording.
When using Chrome (ll/CrQ,), or Metal tape, make
sure you do not cover the hole intended for the tape
formulation check.
Slack in the tape inside of the cassette shell can be
corrected by simply inserting a pencil into one of the
spools and winding it until all the slack is taken up.
After putting a cassette tape back into its case, store in a
location away from exposure to direct sunlight, humidity,
high temperatures, and magnetic fields (away from
television sets, speakers, etc.). High temperatures and
humidity will damage the tape itself, while exposure to
magnetic fields may cause a loss of recorded material.
In order to make recordings with the best possible signal-
to-noise ratio, it is important to set the recording level at
the highest leve! possible without introducting distortion.
Push the REC/PAUSE button to engage the Rec Standby
mode, and play a section of the program to be recorded.
Watch the PEAK level meters and adjust the REC LEVEL
controls so that the average meter reading is between
—5 dB and + 3 dB, with occasional peaks no higher than
+5 dB.
The peak value over the O dB is held for a while.

1. Make sure that all power cord connections between
the timer and amplifier are properly made. No change
in any of the other connections between deck and
amplifier, etc., is necessary.
2. After turning on the power to each component, select
the station on your tuner which you want to record and
turn down the volume on your amplifier. This will have
no effect on the recording signal level. Remember to
set the proper recording level.
3. Set the timer to the desired times. It is advisable to set
the timer to begin recording slightly before the actual
recording time, and end slightly after the actual
recording time, so that you leave some room for later
editing. |
4. Set the AUTO MODE selector to the TIMER REC
5. The timer will send power to the amplifier, tuner and
deck at the preset time, turning all the components on
and initiating the recording mode.
if the tape cannot be ejected after timer recording, turn
the AUTO MODE selector OFF and the K-540's POWER
switch ON; the tape can then be ejected.
ea Timer Playback
1. All connections are the same as for timer recording.
2. Turn on the amplifier and adjust the Volume and Tone
controls. |
3. Set the input mode selector of your amplifier to the
Tape mode.
4. Set the timer to the time you wish to start and stop
5. Set the AUTO MODE selector to the TIMER PLAY
position. | |
6. Atthe preset time, the timer will turn power on to the
amplifier and tape deck and begin playback. It will shut
power OFF, at the preset time as well ending playback.
After using your K-540 for a certain length of time, itis
possible that the sound of your tapes may deteriorate with
"fading, vibration, or noise as a noticeable result. This is
caused by an accumulation of dirt or dust on the heads,
capstans, or pinch rollers, and magnetization of the heads.
It is advisable to clean the capstan and pinch roller. Use a
commonly available cotton swab and head cleaning
solution to do this, or use a special head cleaning tape.
Head demagnetizers are also commonly available.
e When cleaning the heads, be careful not to apply
unnecessary pressure.
e When demagnetizing the heads, be sure to follow the
instructions of the head demagnetizer carefully.
e For better access to the head assembly, the cassette
compartment cover is detachable by pulling upward.
To reattach it, reverse the same procedure.
