The XXL XA series is a line of high power, low profile, professional Power Amplifiers with advanced features and
great reliability. They deliver tremendous power in only two rack spaces, providing high level performance under the
most demanding conditions. An automatic speed fan matches cooling capacity with heat requirements. The amplifier
frame contains all solid-state circuitry, using complementary silicon output devices. The amplifier is supplied with a single
moulded AC cord having an appropriate AC plug for the intended operating voltage. The amplifier employs forced air
cooling with a variable speed fan for minimum acoustic noise. Air flow is from rear to front to avoid temperature rise
inside the Rack. The amplifier contains two independent channels, with separate AC transformer secondaries, power
supplies and protection system. All protection systems, except the main AC one, are self resetting upon removal of fault,
and the remaining channel shall continue to operate. Each channel has independent protective circuitry against open
circuit, short circuit, mismatched loads and over temperature. Each channel has also a main LED that becomes green
for power-on indicator and red for muting or protection, another red LED that shows true amplifier clipping and a yellow
one for the Limiter stage. The power outputs employ standard power connectors. All the inputs are electronically balanced
and an high quality audio transformer can be added on the input stage of each channel.
