form the very thin work on frequencies to tremendous and creative effects. The Xpass Filter
is a mono filter that accepts all the stereo sources. Both sides of the stereo will be mixed
before the filtering unit. All the sound levels are accepted: instrument, line and phono.
You can plug guitar, bass, electromechanical keyboards (Rhodes,Wurltizer, Clavinet, etc),
analog or numeric synthesizers, samplers, expanders, track recorder, cd players, turntable,
computer, etc.
Important: You’ll find many different audio levels with the cds. You’ll just have to
compensate this different levels with the input and output potentiometer. This
concerns principally the manipulation that consists in switching vinyl or cd in a
parallel wiring configuration.
III- Wiring and audio configurations
Whatever you plug in the Xpass Filter, there are generally two ways of wiring the Xpass Filter.
The first way consists in plugging the Xpass Filter in serial: Sound source →Xpass Filter →
Monitor
The second one consists in plugging the Xpass Filter in parallel, via the send/return
connections on your mixing console. The level adjustment will be easier in the serial mode.
Concerning the inputs, the Xpass Filter is fully equipped :
- A phono input with RCA plugs that drives the source to a high quality RIAA preamp with a
perfect equalization correction to optimize the vinyl sound.
- A line input (¼’ jack) that accept mono or stereo plugs to wire all line level sources.
- An instrument input (¼’ jack)
- A 0-5 volts (¼’ jack) for a tension command to use with a midi/cv converter or a pedal for
example. By this way, you can pilot the cutoff frequency of the filter.
- An output (¼’ jack) that permits to send a « pseudostereo « .
Important: to plug a stereophonic peripheral in the Xpass Filter, try to use a « Y »
¼’ jack as shown below. To connect the Xpass Filter to your monitoring system,
try to use the same type of wiring.
If you use a « vintage » analog synthesizer for example, you can plug it with a
mono ¼’ jack in the line input. The guitar and bass type instruments have to be
plugged with a ¼’ mono jack. If you want to use a microphone, you just have to
preamplify it. The preamp has to be plugged in the line input.
You’re now ready to use the Xpass Filter !!!
