ADJUSTING THE OVERALL BALANCE OF THE SYSTEM
Once you complete matching the signal level, the following steps ought to be made
to set the overall linearity of the system.
This may be necessary due to the relative efficiencies of each of the speakers.
For example, smaller speakers normally are more efficient then woofers and play
louder faster at given equal power (See Figure # 4)
The
PLXR3B's
individual output level controls allow compensation for this.
It is important to understand that the output levels are not designed to add gain to
the signal. Actually, the output level controls attenuate (reduce signal gain).
It is for this reason that in the following steps we will start with the output levels at
the maximum position then reduce the outputs to balance the system.
For example, if you like heavy bass, you will most likely leave the
SUBWOOFER
OUTPUT LEVEL
at the maximum position and reduce the
MID
and
HIGH
output
levels by 1/2 (50%). This will allow the bass to reach a high output faster than
MID
and
HIGH
speakers.
If you wish to increase the
MID
and
HIGH
frequencies, reduce the
SUBWOOFER
OUTPUT LEVEL
.
