2.3.1 The ULTRATWIN GX212 as master
The SLAVE IN jacks can also be used to amplify the ULTRATWINs signal with an additional power amp. Use
two conventional instrument cables (one conductor plus shielding) having a mono 1/4" plug on the one end, and
a stereo 1/4" plug on the other. On the stereo plug, tip and ring should be bridged. To route the ULTRATWINs
audio signal to the external power amp, connect the stereo plug to the SLAVE IN jacks and the mono plug to
the power amp input jacks.

2.3.2 The ULTRATWIN GX212 as slave, driven by an external amp/preamp
To operate the stereo power stage of your ULTRATWIN from an external amplifier/preamp, connect the line
outputs of the external amp to the SLAVE IN jacks on the GX212. Use conventional instrument cables with
mono 1/4" plug. If you use a mono preamp, its signal should be split up among the two SLAVE IN inputs of your
ULTRATWIN, using a commercial Y cable.
