Setting Bass and Treble Controls on Receiver or Amplifi er
Normally we recommend that you set the “Bass” and “Treble” controls on fl at (or off, or 0 dB). Same applies
for a graphic equalizer; we recommend that you leave it fl at (or off). This will give you the most accurate and
natural sound. If you want more bass, raise your subwoofer’s “Level” control (or raise the subwoofer level on
you’re a/v receiver), keeping in mind that even a little turn of the knob can make a big difference in the sound.
The reason for this recommendation is that we have discovered what is often thought to be improper sounding
speakers is, in fact, a problem caused by the use of tone controls. When in doubt, leave them out (fl at); this almost
always results in the best possible and most natural sounding system performance.
Complete Home Theater Systems
We strongly suggest that you use matching GoldenEar Technology Invisa ® loudspeakers and a ForceField ™
subwoofer, for your complete GoldenEar home theater system. Invisa ® MPX speakers are designed to be
used as front, rear and/or side surround speakers, with exceptional results for both music and movies. Of particular
note, the GoldenEar ForceField Subs have been designed specifi cally to make a perfect match with the Invisa
®
MPX speakers.
Using the Invisa ® MPX in a Multi-Channel Home Theater Application
When using the Invisa ® MPX as part of a home theater system that includes powered subwoofer(s), it is
extremely important that bass is directed to the subwoofer and NOT the Invisa ® MPX speakers. This is done
through the use of a high-pass fi lter, implemented as part of the setup of the bass management system of
your home theater receiver/processor (see below).
Setting Channel Levels and Bass Management
Multi-channel surround sound systems have bass management systems (systems which direct the bass to
the various channels) which vary from unit to unit. This bass management system must be properly adjusted,
in particular it is extremely important that bass is directed to the subwoofer and NOT the Invisa ® speakers in these
setups, through use of bass management settings as described below. Many problems relating to the overall sound
of the system can be traced back to improper bass management. Also note that Multi-channel surround sound
systems have a critical channel balancing procedure for setting the level for all speakers which must be followed if
the system is to perform properly. Many problems relating to the overall sound of the system can be clearly traced
back to improper system balance.
Home Theater System Bass Management Settings: On your Home Theater receiver or A/V processor’s Speaker
Setup Menu, set speaker to “Small” for all channels using Invisa
® MPX speakers, and set Subwoofer to “Yes.”
The standard 80Hz crossover is the recommended setting (or at least starting point) for the crossover setting.
Setting Channel Levels: On your receiver or A/V processor’s Speaker Level Calibration Menu, set each speaker
(channel) in the system to the same volume level. While you can get reasonable results doing this by ear, it is best
to use an inexpensive Sound Pressure (SPL) meter to get better channel to channel balance. Some new receivers
and processors have Auto Set Up functions that use a supplied microphone to set levels automatically.
