LCD Contrast parameter
Use the LCD Contrast parameter to set the con-
trast of the LCD screen. Depending on the ambi-
ent light in the room, different settings may have
more or less effect.
UP/DN Function
Use the UP/DN Function parameter to define
what should happen when you press the DOWN
and UP footswitches simultaneously.
Please note that when you connect a TC-Hel-
icon to the PEDAL connector of your
Play Acoustic, the default behavior of the UP/DN
function changes from “Loop” to “Set Key.”
Looping setting
Pressing the DOWN and UP footswitches simul-
taneously will enter and exit Loop mode, allow-
ing you to play and record loops.
Set Key setting
Pressing the DOWN and UP footswitches simul-
taneously will enter Set Key/Scale mode, allow-
ing you to manually set the key and scale for a
song.
Lead Delay parameter
Use the Lead Delay parameter to delay the in-
coming vocal signal very slightly to compensate
for the small amount of latency introduced when
effects are processed by the device.
This delay ensures that the processed/generated
voices – like harmonies – will be perfectly in sync
with the lead vocal.
None setting
No delay compensation is used.
Voice Sync setting
The lead vocal is delayed an amount equal to the
maximum latency of the system with all effects
turned on.
Auto setting
The lead vocal will be delayed by an amount
equal to the latency of the currently enabled
effect blocks. Using more effect blocks will in-
crease the latency compensation amount.
Tune Reference parameter
Use the Tune Reference parameter to define the
reference frequency for the guitar tuner and any
Harmony or HardTune effects. The default is
440 Hz (A), which can be changed in 0.5 Hz in-
crements.
Aux to Main Out parameter
Use the Aux to Main Out parameter to define
wether the Aux signal should be sent to the XLR
outputs. Set this parameter to Off if you would
like to hear the Aux input only in your head-
phones. This is useful for in-ear monitoring ap-
plications. You can send a full monitor mix to
the Aux input, and you will only hear it over your
headphones or in-ear monitors.
Aux In Type parameter
The Aux In Type function will perform magical
calculations to help make harmonies more ac-
curate.
Live setting
Use the Live setting when you are playing live
or processing a recorded vocal track from your
DAW using the aux in to provide guide tracks.
Tracks setting
Use the Tracks setting when you are singing
along with prerecorded music, e.g. from an MP3
player.
Monitor setting
Use the Monitor setting to remove incoming Aux
signals from the main output. This allows you to
hear Aux audio via headphones, but not pass
that audio to the PA. This is a great solution for
cost effective in-ear monitoring.
The TC-Helicon
Guitar & Headphone Cable
is an excellent way to combine your guitar and
headphone signals into a single cable. For more
