USER MANUAL
EKKO EK-1 User Manual rev. 1.0.3
CONGRATULATIONS!
You are now the owner of an EKKO EK-1 delay pedal!
EKKO is a high-quality aluminum, standard semi-analog delay pedal with true bypass. Semi-analog
means that the direct signal from your guitar is always direct through, whether the pedal is in
bypass mode or not. It can be controlled like a stand-alone effects pedal or using the AEROTM AE-1
wireless controller (optional):

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
TIME

INPUT/OUTPUT SETUPS
The Aalberg EKKOTM EK-1 Delay Pedal offers the following mono/stereo configurations:
1. Mono in/Mono out
2. Ping-pong stereo
3. Dry/wet split
4. Dual mono
1. Mono in/Mono out
Connect your instrument to Mono in and the
amplifier to Mono out.
2. Ping-pong stereo
Connect your instrument to Mono in then connect
one amplifier to Mono out and another amplifier
to Stereo out. The echoes of the direct signal will now alternate between the two outputs.

9
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. Dual mono
This is useful if you want to maintain the stereo path for pedals in the signal chain. Connect
the stereo outs from the previous pedal to both inputs on the EKKO (Mono in = left, Stereo
in = right).

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. 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 prototyping stages (from left to right): “The
Coffee Filter”, 2010 – “The Tank”, 2012 – “Prototype 3”, 2013 - the final product, 2015)
