KMA Machines Horizont Stereo Phaser Pedal

Besides the more common phaser controls, the KMA Machines Horizont offers a plethora of new and exciting options for all the interstellar tone chasers out there. To greatly broaden the range of phasing tones available, we implemented a digital LFO with no less than eight different waveforms: Ramp Up/Down, Sine/Triangle/Square wave, a sweeping waveform, Sample & Hold and a random slope waveform going from 20s down to 40ms.

The implemented envelope generator is one of Horizont's absolute key features. It transforms your input signal into a control source to modulate the speed of the digitally controlled LFO or lets you manually phase for a resonant touch wah-like sound, depending on the state of the SWP- and SPURTCONTROL-Switch.

Set the SPURTCONTROL switch to LFO to let the SPURT knob adjust the internal phasing speed. However, by flicking the switch to ENV (Envelope) mode, it allows you to dynamically modulate the speed along the full LFO speed range, based on how loud the input source is (e.g. when you attack the strings hard). You can also combine the SPURT knob and the envelope by flicking the toggle to LFO+ENV where SPURT then sets the minimum speed. For even more control, you can even plug in an external expression pedal/CV-source (0 - 5 V) to alter the minimum speed on-the-fly or you can use the TAP TEMPO switch (tap just twice) to set the speed to fit in with the tempo of your music.

The EXP-Mode switch also lets you choose between a ma- nual phasing mode, controlled by an expression-pedal or an external CV source. Setting the EXP-Mode switch to the middle position will disable any external expression control. The SWP (Sweep) switch lets you decide to use either the LFO or the envelope of your instrument signal to control the phasing.

The envelope can be set to upwards or downwards op- eration via the ENV switch, seeing the LFO either slowing down or speeding up, or flipping the orientation when phasing manually from lows to highs and vice versa. In conjunction with the FUEL (Sensitivity) and the DECAY controls, the envelope can be tailored perfectly to your needs.

KMA kept the EMPH (Emphasis) mode from the original Astrospurt Phaser, but have reworked and refined it extensively for the Horizont. The four toggle-switches determine the stage in which the phase-shifted signal is fed back into itself, while the REG (Regeneration) control sets the feedback amount. They also smoothed out the overall sound of the EMPH mode for a more pronounced, and crisp vocal-like tone. Each of the different switch variations and turn of the REG control will yield different results, seeing you discover new wild, fuzzy and noisy galaxies as you travel deeper down this sonic wormhole.

In order for you to levitate through spacetime, KMA have also added a stereo output to the Horizont. You can switch between a standard stereo output or a panning output, via the STEREOPAN switch. Synchronized with the LFO speed, the upper cycle of the LFO sends the signal to the OUT1 and the bottom cycle to the OUT2. This is without a shadow of a doubt the most liquid and astonishing phasing experience you’ll ever embark upon. But wait, there’s more! Stop and take a deep breath, set the MIX control to fully clean and the Horizont is transformed into a Tremolo on-the-spot, with all the other aforementioned features.

Last but by no means least, KMA equipped the Horizont with an FX-Loop right in front of the phase-shifting line. This enables you to add your own secret sonic weapons to this spaceship, seeing you create your very own unique phasing sounds. They have also increased the pedal’s headroom drastically by boosting the internal circuit voltage to 18V, from the regular 9 V input, to give the cleanest phasing possible no matter what instrument or line source you use.

But don’t be fooled by all of these seemingly complex features, the Horizont is a super intuitive next generation phaser that’ll see your tone take flight in seconds flat. Whether you are looking for traditional phasing sounds, experimental synthetic soundscapes or super dynamical sonic endeavors, the Horizont will have you covered to infinity and beyond.

Powered by an optional standard 9 V DC (max) PSU (negative center, 2.1 mm, approx. 75 mA current draw)

Every pedal is designed, assembled, silkscreened, tested and numbered by hand in KMA's small workshop. Doublesided PCBs are designed, tested and assembled by KMA, to guarantee a high quality standard and keep the price of the pedals reasonable. The use of an indestructible powdercoated die-cast enclosure ensures a maximum durability.
