Features
e Atwo-speed controlled fan provides forced-air cooling of
the interior, guaranteeing excellent reliability.
e Separate fans for air intake and exhaust for even greater
cooling effect.
e This unit is equipped with a temperature sensor, DC
sensor, muting circuits and ASO protection circuits (*1) to
protect the unit (and speaker systems) in the event of a
malfunction.
e Ground switch allows hum-causing loops to be avoided.
e Limiter switch prevents problems that can arise from
excessive input. (SRA-540/SRA-800 only)
* Mode switch allow selection of either stereo or BTL
connection, making this the perfect amp for any applica-
tion.
¢ Theamplifier contains XLR-3-31 type, 1/4 inch TRS phone
type and Barrier Strip input connectors, all of which are
balanced inputs.
e The high power output of the unit is made possible by
large power toroidal transformers and large capacitors.
e Complementary Linear Outputs technology (*2) is fea-
tured for reproduction of unprecedentedly powerful
sounds.

*1 ASO Protection Circuits:
ASO stands for Area of Safe Operation, where the unit can
function normally without damage to the power transistors.
The ASO protection circuits protect the power transistors on
the output line when excessive power levels or loads occur.
*2 Complementary Linear Outputs Circuit
Conventional SEPP, emitter follower output circuits apply a
100 % voltage feedback in the final stage, causing even the
playback signal to be averaged, resulting in a lack-luster
sound. However this unit uses a complementary linear
output circuit with a collector output circuit as the final
output stage, producing highly efficient and linear output
characteristics, and the ability to produce sharp and powerful
transient attacks.
