GETTING STARTED
To get your pedal up and running you need a standard 9V DC, 2.1 mm plug,
center negative power supply (minimum 250 mA). You will find the connector at
the back of your pedal.
The pedal supports both mono and stereo connections. Combinations of these
will lead to different properties in the output signal. See the Input/output setups
section for further explanations.
CONTROLS
SPEED Adjust the speed of the chorus/flanger effect
INTENSITY
Adjust the dry/wet mix between the input signal and the effect
signal. In Flanger mode, this parameter also adjusts the feedback
amount.
DEPTH Adjust the degree of pitch shifting in the chorus/flanger effect.
Depth set to minimum means no effect.
FX SELECT/
FLANGER
FX-SELECT – Choose active effect parameter (SPEED, INTENSITY
or DEPTH) for wireless control (optional)
FLANGER – press and hold the FX-SELECT footswitch to toggle
between the two modes:
FLANGER (no light): Chorus mode active
FLANGER (light): Flanger mode active

INPUT/OUTPUT SETUPS
The KOR KO-1 Chorus/Flanger offers the following mono/stereo configurations:
1. Mono in/Mono out
2. Mono to stereo spread
3. Dry/wet split
4. Stereo to stereo spread
1. Mono in/Mono out
Connect your instrument to Mono in and the amplifier to Mono out.
2. Mono to stereo spread
Connect your instrument to Mono in. Then connect one amplifier to Mono out, and
another amplifier to Stereo out. The stereo spread effect is a combination of phase
invertion and a continous panning of the signal from side to side, resulting in a wide
stereo effect.
3. Dry/wet split
Connecting your instrument to Stereo in will split the dry wet signal as follows:
Mono out: 100% wet signal
Stereo out: 100% dry signal
4. Stereo to stereo spread
By plugging into both the mono and stereo inputs, and both mono and stereo
outputs, you will obtain the same stereo spread effect as for 2. Mono to stereo spread.
This is useful if you want to maintain the stereo image from the output of another pedal
in your signal chain.

HISTORY
The inspiration for the delay pedals with wireless controller came to guitar player and
inventor Rune Aalberg Alstad back in 2009, when he was tired of having to run over
to the pedals and bend down all the time to change the effect settings. In 2012 he
met the engineer Torkild Indstøy and the entrepreneur Aleksander Torstensen, and five
years later, after lots of testing and prototyping we are proud to introduce the world’s
first EKKO EK-1 Delay Pedal with the AERO AE-1 Wireless Controller. (Below you
can see the different development stages (from left to right): “The Coffee Filter”, 2010
– “The Tank”, 2012 – “Prototype 3”, 2013, “Prototype 4, 2014” - The final product,
2015)
