LCD Contrast parameter
The LCD Contrast parameter adjusts the display to best match
ambient lighting.
Mic Boost parameter
The Low and High settings for the Mic Boost parameter add
digital gain to the incoming mic signal so that quiet singing and/
or low output microphones can use the middle, broader adjust-
ment range of the Input knob.
Global Key parameter
The Global Key parameter can be useful when you’ve found a
good fixed key for your song but want to try different presets.
On setting
When Global Key is set to On, all presets are set to the same
Harmony Key – whether it is set to Auto or a fixed key such as
E Major 2. Global Key can be set by either the Key parameter
in the Harmony edit menu (there is no need to store) or via
the Switch-3.
Off setting (default)
When Global Key is set to Off, individual presets may be stored
with any Key setting.
Tune Reference parameter
The Tune Reference parameter trims the overall tuning refer-
ence for the Harmony and Hardtune effect blocks with respect
to A = 440 Hz. This parameter is very useful when an accompa-
nying instrument has changed overall pitch, such as a piano that
is in tune with itself – but not with A = 440 Hz.
Aux In Type parameter
The Aux In Type parameter helps reduce Harmony chord
change latency when you’re singing to music coming from an
MP3 player connected to the Aux input. It does so by delaying
the MP3 audio signal slightly.
Live setting
When setting the Aux In Type parameter to Live, no delay is
added.
Tracks setting (default)
When setting the Aux In Type parameter to Tracks, delay is
added to the incoming audio.
