Fig. 3.1 shows how to connect your keyboard, a drum machine and a microphone 

to the ULTRATONE. Additionally a CD player is connected to the AUX IN input to 

feed in a playback. With the footswitch you can activate/deactivate the internal 

effects processor.
Fig. 3.2 shows a recommended setup for amplifying the sound of your 

ULTRATONE using a sound reinforcement system of any size. This way, you can 

also use your amp for playing live or for rehearsals with your band.

The ULTRATONE features 1/4" connectors on inputs and outputs plus additional 

balanced XLR connectors for channel 1 input and Line Out outputs (K3000FX and 

K1800FX). More detailed information can be found in chapter 5, “Specifications.”
