Electro-Harmonix 1 ECHO Operation Instructions

Congratulations on your purchase of the #1 Echo! The #1 Echo is a result of
Electro-Harmonix's long experience in designing world-class delay lines. It
presents you with musical, accurate and warm delays that surpass the very
best performance instruments on the market. Reading these instructions
carefully will ensure that you will get the most out of your #1 Echo.
WARNING: Use only the US96DC-200BI adapter that the #1 Echo
comes supplied with. Do not use any other AC adapters. Using other AC
adapters, even those made by Electro-Harmonix, could cause harm to the
unit, the adapter or you. The #1 Echo does not use batteries.
The #1 Echo is an instrument that will echo any note or audio event that you
play through it. You can control the time duration that will be applied
between the played note and the echoed note. The echo will sound exactly
the same as the original. The delay time range is from 10ms up to 2
seconds. Additionally you can choose the number of times that you want the
echo repeated. This is known as feedback, which has a dedicated control.
As you start to use the #1 Echo, invest some time to experiment with the
Controls and how they interact. You will discover very interesting possibilities
including double tracking (where the notes are a little offset) all the way to
long delays that allow you to continuously play new lines on top of previous
events. The longer the duration, the more possibilities you have to add new
notes to the original. As you add more repeats with a longer duration you
can build up complex textures that can be very effective.
