1. Setup

1.1 Unpacking

Carefully remove the Stax LTL-02 Twin Looper Pedal from its packaging. Verify that all included components are present: the Twin Looper pedal, a USB cable, and this user manual.

1.2 Power Connection

The Twin Looper pedal requires a 9V AC adapter with a positive tip (not included). Connect the adapter to the DC 9V input jack on the pedal. Ensure the power supply meets these specifications to prevent damage to the unit.

1.3 Audio Connections

Connect your instrument (electric guitar or bass) to the LEFT IN (mono) or LEFT IN and RIGHT IN (stereo) 1/4-inch input jacks. Connect the LEFT OUT (mono) or LEFT OUT and RIGHT OUT (stereo) 1/4-inch output jacks to your amplifier or audio interface.

1.4 USB Connection

The USB port is for data transfer (importing/exporting loops) only. It is not for powering the device. Connect the provided USB cable from the pedal's USB port to a computer running a Windows operating system for software interaction.
