xlter 500
Welcome to lter wonderland!
Thank you very much for purchasing the xlter 500 – one of
the quite few true linked stereo EQs in the market.
The xlter 500 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 potenti-
ometers and low tolerance lm capacitors.
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 stages with shielded coils for a glorious
top end.
With its exceptionally open sound, straight transient projec-
tion and solid punch, the xlter is the perfect match for your
xpressor – or any other piece of delicious outboard gear!

Compatibility
The xlter 500 module requires installation into an API 500 se-
ries compatible rack frame (not included). It needs the power
supply and the audio connectors provided by this frame, and
cannot be used for its intended purpose by itself.
The current consumption is 210 milliamperes (105 mA per
slot) at +/- 16 volts DC. This is actually more than some other
500 series modules consume as a result of the class-A design
of the audio path of the xlter 500.
Most API 500 compatible racks meet this requirement with-
out problems, but there might be a limit on how many units
can be installed in a single rack. In case of doubt, please check
with the manufacturer of your specic rack.
Installation
Just follow these easy steps to install the xlter 500 module:
1. Switch your API 500 series compatible rack o and discon-
nect the power cable from mains.
2. Insert the module into two free slots of your rack. Make sure
both PCB connectors match with the rack connectors.
3. Gently push the module in place – do not use any excessive
force!
4. Tighten the front panel with four screws provided by your
rack manufacturer.
5. Connect your XLR audio cables (see page 6 for more info)
and power up your rack.
That should do it. Have lots of fun with your xlter 500!

Passive Massage
Mmm... The beautiful sheen a passive EQ adds on top of every-
thing. We all love it, we all need it!
Well, here is the good news: In addition to its four exible ac-
tive bands, the xlter 500 features a switchable xed LC lter
for polishing the high frequency range.
The lter mainly consists of a capacitor and a coil per channel,
but unlike the standard shelving designs, it has a slight reso-
nance peak at 12 kHz and starts to fall o at 17 kHz.
This way, the saturation-like storage eect of the shielded
coil focuses on the area around the peak without pushing the
complete high frequency spectrum too much.
