Tuning the 9 Bands of equalization is set by your listening
preference as dierent music genre are produced with
dierent quality and dierent equalizations. The AP-9EQ was
designed to help you compensate these recording dierences by
allowing you to ne tune your system for your listening enjoyment.
The 9 Bands of equalization does not aect your
subwoofer channel as your subwoofer channel already has its
own independent frequency range and volume knob. Instead the
equalization bands will only aect the Front and Rear Outputs.
- Bass (80Hz Centered): Use this knob sparingly as most
coaxials speakers and components cannot handle 18dB of
boost. However, in some music you will nd that turning up this
knob will enhance the low frequency output.
- Upper Bass (120Hz Centered): Use this knob to control
frequencies that are above subwoofer bass and below midrange
which is also called low order harmonics. This range is normally
associated with Male vocals, brass instruments.
- Upper Bass (200Hz Centered): Use this knob to control
frequencies that are associated lower end of vocals, deeper
notes from synthesizers, low brass and piano.
- Lower Midrange (500Hz Centered): Use this knob to control
the lower midrange frequencies. Adding to much boost in this
region makes things sound muddy and congested. Not adding
enough boost in this region can make sound seem thin and weak.
- Midrange (1kHz Centered): Use this knob to control the
midrange frequencies. Adding volume here should be used
sparingly as too much can give things a metallic sound and
can wear down on your ears quickly if raised too much.
- Upper Midrange (3kHz Centered): Use this knob to control the
upper midrange frequencies. Adding or reducing here can raise
or lower the snap of higher instrumentation quickly such as
acoustic and electric guitar and piano.
