CONFIGURATIONS AND CONTROLS
The Halo Chorus can be set up in three basic configurations depending on your input and
output requirements - mono, mono in / stereo out, and stereo in / stereo out.
IMPORTANT - Stereo amp configurations and grounding: Use caution whenever connecting
the Halo Chorus to multiple amplifiers. Ensure both amps are safely grounded and share the
same ground. If in doubt, ask a qualified technician - ground faults can result in severe injury
and death.
MONO
In this configuration, the input signal (either from a guitar or from the previous pedal in
the chain) is brought into the ‘
<
’ input, with the output taken from the ‘
<
’ output. The in-
ternal circuitry will automatically configure to parallel sum both the ‘chorus’ pitch modu-
lation and ‘vibe’ phase modulation effects, illustrated below in Figure 1:

In the mono configuration, the 180 degree phase switch has no effect on the output sound.
MONO IN / STEREO OUT
In this configuration, the input signal (either from a guitar or from the previous pedal in
the chain) is brought into the ‘
<
’ input, with the output taken from both the ‘
<
’ and ‘
<<
‘
outputs. The internal circuitry automatically configures to the topology shown below in
