FUSE:
safety holder for the mains fuse (AT 1250mA). The fuse holder can be removed by
depressing its fixings on both sides. The fuse can then be changed.
(17) VOLTAGE SELECTOR, 220-240 VOLTS:
on all European models, the ATS 120 can be set to operate on either a 220 or 240 volt
supply by rotating the insert incorporated in the fuse holder. The value visible in the
fuse holder‘s window is the one which is operative.
Models for North America and Japan are equipped at the factory with different
transformers which are pre-set to the appropriate mains voltage standards.

SPEAKERS:
the ATS 120 has two sockets for connecting loudspeakers or cabinets. The combined
impedance of all loudspeakers used must never be less than 4 Ohms!
The loudspeaker fitted to the combo version has an 8 Ohms impedance. Any further
speaker cabinet connected to it should have an impedance of either 8 or 16 Ohms.
For the ATS 120 Head: if a single speaker cabinet is used, its impedance should be
either 4 Ohms or 8 Ohms. When two cabinets are used, each one should have an
impedance of either 8 or 16 Ohms.
(19) HEADPHONES:
socket for standard stereo headphones. The frequency response of the signal fed to the
headphone socket is tailored to reproduce the characteristics of a typical guitar speaker.
This produces a “comfortable” sound which is suitable even for lengthy practice sessions.

POWER AMP IN AND LINE OUT:
these two sockets have a variety of uses.
LINE OUT:
this provides access to the
preamplifier signal (before the poweramp), which can then be send to a mixing console
