Welcome to lter wonderland!
Thank you very much for purchasing the xlter – one of the quite few
true linked stereo EQs in the market.
The xlter gives you the expensive sound of an all class-A equalizer in a
surprisingly aordable package, with a precise stereo image based on
computer-selected, stepped potentiometers and low tolerance lm ca-
pacitors.
This EQ is serious about exibility. It oers high and low shelf bands
which can be switched into high and low cut lters with resonance, two
mid peak lters with wide and narrow Q, plus additional passive LC stag-
es with shielded coils for a glorious top end.
With its exceptionally open sound, straight transient projection and solid
punch, the xlter is the perfect match for your xpressor – or any other
piece of delicious outboard gear!
