Less than 10 minutes left—replace battery. Low-level
white noise appears in the output to give audible confirmation of battery status.
Gear Shift knob flashes
blue
approximately every four seconds:
After 10 minutes
without activity, LPX goes into “sleep” mode. (Sleep mode still drains the battery
somewhat; to prevent this, turn the guitar off completely.) Move the Gear Shift knob
to “wake up” LPX.
Connecting to Amplification
LPX’s unbalanced output can drive anything from a guitar amp, to a mixing board’s low-
impedance input, to a computer’s audio interface. Separate cables are included to connect
LPX to either 1/4” phone jacks (balanced or unbalanced, with ring not connected) or XLR
inputs (pin 2 hot, pin 1 ground, and pin 3 not connected).
Note: Use only the supplied
stereo cable to connect LPX to the G-Node interface.
Caution!
When patching LPX to a balanced XLR input,
make sure the XLR input does not
have phantom power enabled.
This could damage LPX’s output.
LPX’s output level is somewhat “hotter” than standard guitars. Start with the amplifier
volume at minimum, then turn up to a comfortable listening level.
Note: LPX produces no
“thump” on power-up or power-down, so you may safely turn LPX on or off even if your
amp is set to high levels.
For a quick audio check, you can plug standard headphones directly into LPX’s output.
However levels will be low, and only in the left earphone.
Required String Gauges
For optimum Robo-Tuner tuning speed and reliability, please use the correct gauge strings.
LPX ships with the recommended string gauge set: High E = .009, B = .011, G = .016
(wound), D = .026, A = .036, low E = .046.
The heaviest gauge permissible string set is high E = .011, low E = .052
The lightest gauge permissible string set is high E = .009, low E = .042.
