switch on the power some moments before you play records for
reproduction. In radio reception, however, the sound can be heard in
about
20
seconds.
2.
Speaker Phasing
When the left and right speakers are attached to the opposite
( +)
and (-)
terminals, the sound level midway between the two speakers will fall,
a deterioration in bass being especially noticeable. Listen to the stereo
recording and switch the SPEAKER PHASE.
It is in proper phasing
if the sound midway between the two speakers becomes full and the
bass tone improves.
3.
HUM BALANCER
Adjust in the following manner: Connect all the lines from the pickup
and to the speakers; switch on the power and turn the volume control
up almost to maximum. Turn the HUM BALANCER with a screwdriver
or coin until hum- an irritating drone- is reduced to minimum.
It
will suffice to adjust it only once- you need not adjust it again.
The hum sometimes decreases depending on the way the amplifier power
cord is plugged into the socket. Choose the position with the least hum.
4.
HOWLING
When the record player is placed directly on top of the speaker case
or close by it, the sound from the speaker travels to the player pickup
needle and causes "howling". It then becomes impossible to raise either
the volume or boost the bass tones. Adjusting the amplifier will not
help since it is not responsible for the howling.
In order to avoid howling, keep the player case and speakers as far apart
as possible. However, if you are forced to place the player on top of
the speaker lay a thick cushion or sponge mat in between.
5.
HEATING OF AMPLIFIER
The upper surface of the amplifier case reaches a considerable temperature
with the elapse of time; but since the W-38 is well designed with this
taken into account, you need not worry about it. However, do not place
anything on top of the case thereby blocking the ventilation holes and
increasing the heat inside.
6.
SPEAKER SWITCH
Turn the SPEAKER (See photograph) to OFF position
only
when you
use the headphone. Keep it at ON position at all other times.
Caution:
Donot raise volume when the switch is in OFF Position with
a stereo headphone disconnected.
Otherwise, it is likely to cause a
breakdown in your amplifier.
