If you have difficulty achieving a suitable balance try experimenting with the speakers'
position, remembering that moving them closer to a wall or corner will produce more bass,
away from walls will give less.
It may take some time, and a number of records before the right setting is achieved.
Once the correct speaker position and contour setting has been established you should be
able to leave the contour setting where it is and ignore it.
USING THE CONTROLS: EXTENSION AND Q FACTOR
Although such information is present on the finest modern recordings it is seldom heard
correctly due mainly to deficiences in the low-frequency performance
of most conventional
loudspeaker systems.
i
In Model 107 these deficiencies can be removed by means of K-UBE's Extension and
Q-Factor controls.
For critical listening to music containing significant low-frequency information (e.g. pipe
organ, synthesiser, piano or percussion) then a setting of 25Hz or 18Hz should be chosen.
The higher settings of 35Hz and 50Hz should be used for less critical listening, when the
source material does not require extension or is of inferior quality. These settings should
also be used if Model 107 is to be used to provide continuous high-level background music
at parties, thus avoiding the possibilities of amplifier overload.
CAUTION: K-UBE applies PRECISELY the right amounts of equalisation to your system.
The use of graphic equalisers, or your amplifier's Bass or Loudness controls is not only
unnecessary, but may lead to the possibility of amplifier overload and consequent
damage.
USING THE CONTROLS: TAPE MONITOR
Note that the signal passing through the K-UBE to the tape deck is not modified.
K-UBE is
only operative on replay. At all other times, leave the TAPE MONITOR button out.
