Electro-Harmonix - XO #1 Echo
Up to two seconds of delay with a warm analog style decay. Sits beautifully in any track or performance. EH has a reputation for quality delays and this number is a prime example.
Blend Knob - When rotated completely
counter clockwise, only the original,
dry signal may be heard. As
you rotate clockwise, the delay signal
is mixed with your dry original signal.
The farther you rotate, the
louder the delay signal becomes.
When rotated to the far right position,
only the delay signal is heard.
Think of the Blend knob as your
balance control between dry and wet
Delay Knob – This knob adjusts the
delay time of your echo. When rotated
to the full counter clockwise
position, the echo will be set to the
shortest delay time of 10 mS. When
the knob is turned to the full
clockwise position, the echo will be set
to the longest delay time of 2 seconds.
Feedback knob – When turned
completely counter clockwise,
feedback is off and you will hear only
the first echo. As the Feedback knob is
rotated clockwise, you will hear more
repeats. At the full clockwise
position the number of repeats will be
so great the #1 Echo will sound like it
is looping the delayed signal
but it is not, the signal will eventually
fade away. This is very effective for
overdubbing parts upon
repeated parts. Multipart phrases and
sonic textures are created this way. At
the very longest settings care
must be taken as some degradation of
tone will occur over an extended
period of time.
Activity LED - When the LED is lit; the
#1 Echo is in effect mode. When the
LED is off, the #1 Echo is
in True Bypass mode. The Footswitch
toggles between effect and bypass
INPUT Jack – This ¼” jack is the audio
input to the #1 Echo. The input
impedance presented at this
jack is 2MΩ.
OUTPUT Jack – This ¼” jack is the
audio output from the #1 Echo. When
the #1 Echo is in Bypass
mode, the OUTPUT jack is connected
directly to the INPUT jack.
9V Power Jack – Connect the AC
Adapter’s plug to the 9V Power Jack.
The AC Adapter must be able to
supply 9VDC at 200mA. The plug’s
inner ring must be negative, the outer
