ä Dual Bandwidth Equalizer – 13 bands
The dual bandwidth design of the EQX
concentrates more control in the lower bass
frequencies where the interior of an auto-
mobile causes problems. The higher fre-
quency controls are spaced on octave
centers to give you complete control up to
16,000 Hz. No simple dash-mount equalizer
gives you this kind of flexibility.

Linkwitz-Riley aren‘t our attorneys – Linkwitz and Riley are a
couple of smart guys who designed a very effective fourth-order
filter for bi-amplified systems. You hear it each time you see a
movie at your local THX theater – we like it! If you want to
know more about this exotic filter, check out our Technical
Paper #102, appropriately titled

ä Level Matching
True standards in car stereo are hard to find.
Every manufacturer has a slightly different
interpretation of things. The input and
output level controls on the EQX Series II
bring everything together. Now any head
unit can be connected to any amplifier and
make the system sound great.

ä Balanced Input
The EQX takes noise rejection a step further
than the average by incorporating balanced
differential input circuitry. By looking at the
output from your source unit in a different
way the EQX can reject up to 60 dB of radi-
ated noise.
