The SA Series mixer amplifiers are audio system amplifiers for high performance sound reinforcement
qstems.lhey are equippecl with o<ternal heat sinks to ensure rrr.ximurr cooling. the front panel is macle from an
aluminium o<trsign: proYqlg strong suplrcrt when the amplifier is rad< mountecl. The SA Si:ries are compact, witl
a maximum rad< height of 88rnm. They have rubber 6et to enable them to be table/clesk mountecl ancl handles to
hcilitate rad( mounting in a standard 482mm wiclth equipment rack
Equippecl with four XLR balanced microphone inputs, one line input (wtrich is ideal for high output devices such as
cct pl4yers and bad<grouncl music sources) and two auiliary inputs,(selectable $ means of a push button on the front
panel of the gmplifier), the SA Series meet the hear1r clemanG of Awtalian Sound Contactors for reliability uncler a
wicle range of ambient ternperatures ancl loacl conclitions.
TECHNICAL FEATURES
Overload protection for the output transistors. . Three pin
IEC mains connector with built in mains fuse. . Four XLR
balanced microphone inputs. ' Two selectable auxiliary
inputs. . One line input. . Tape recorder output by means of
ctual RCA phone sockets. . Balanced XLR output socket

indication.
OPTIONAL ACCESSORIES
MUfING KIT TX301O Plug in moclule provides voice
operated muting of all inputs when connected to
microphone input one.
TX30ll Line conversion module, converts any balanced
mic input to line input sensitivity (250mv)
ISOLATION TRANSfORMER SA40l2 Plug in microphone
line input transformer, provides a balanced isolated mic
input, when pluggecl into any of the four active balanced
microphone inputs, (ideal for long mic lines).
TONL GENERATORS; Four tone generators can be pluggecl
into a socket providecl inside the amplifier. A feature of
these generators is their automatic muting of all auxiliaD/
inputs, once they are activated.
