ULTRATWIN GX212
The mains connection of the ULTRATWIN is made by using the enclosed mains cable and a standard IEC
receptacle. It meets all of the international safety certification requirements.
+ Please make sure that all units have a proper ground connection. For your own safety, never
remove or disable the ground conductor of the unit or of the AC power cable.
The MIDI connection (IN) is made over standardized DIN plug-in connectors. An optocoupler has been used for
isolated data communications.

These are the ULTRATWINs 1/4" PHONE JACK INPUTS to which you can connect your guitar. The
HIINPUT has been designed for low-output guitars (e.g. those equipped with single coil pickups), while
the LO INPUT should be used for guitars with very high output power (e.g. guitars with humbuckers).
Use a commercial 1/4" mono cable (please no DIY (Do It Yourself), better ask your specialized retailer),
with good mechanical and electrical shielding, so as to avoid unpleasant surprises during rehearsals or
concerts.

The CLEAN channels CLEAN VOLUME control determines the volume of the clean channel.

The BASS control in the EQ section allows you to boost or cut the bass frequencies in the CLEAN
channel.
4
With the MID control you can boost/cut the midrange frequencies in the CLEAN channel.
5
The TREBLE control adjusts the CLEAN channels upper frequency range.
+ Please note that with all three EQ controls in the CLEAN channel set fully to the left, there will
be no signal sent to the speaker, which is due to the classical and extremely efficient EQ
circuit used in the ULTRATWIN.

Press the CHANNEL button to toggle between the CLEAN and OVERDRIVE channels. When the
OVERDRIVE channel is on, the associated LED lights up.
