ABOUT THE CX POWER AMPLIFIERS
Thank you for purchasing a CX Power Amplifier, a reference-quali-
ty amplifier, which is based on the award-winning LX amplifier and
is designed to meet the highest standards of power and perform-
ance under even the most extreme operating conditions. Equipped
with advanced thermal, current, DC, and speaker protection, the
CX amplifiers deliver reliable and exceptional performance with
most loudspeakers, including mismatched, reactive, and unusual
loads. In addition, the CX amplifiers include protection against
short circuits, component failures, miswiring, and internal faults.
Available in seven or five channel versions, the CX amplifiers
deliver high-power performance. Each 140-Watt channel includes
four custom-designed, hand-graded output transistors All chan-
nels are capable of driving speaker impedances of 2Ω and above.
Complemented by gold-plated speaker output connectors, the rear
panel includes selectable balanced or unbalanced audio input via
RCA and XLR connectors. A trigger input connector allows the CX
amplifiers to be controlled with associated components such as the
MC-12 or MC-8 Digital Controller. In addition, a ground lift switch
for each channel can be used to eliminate audible hum caused by
multiple grounding paths.
The CX amplifiers include advanced thermal, current, and DC
protection for each channel. Thermal protection monitors the
temperature of the chassis and heatsinks and automatically deacti-
vates the specific channel(s) when they exceed their normal safe
operating temperature. Current protection ensures that the
output transistors are protected by limiting the current capability
which is determined by the output voltage, while DC protection
prevents DC and frequencies below 10Hz from reaching the speak-
ers. Dedicated channel status LEDs are located on the front panel
to provide at-a-glance viewing of channel status at all times.
With THX Ultra2 Certification, the CX amplifiers are certified to
meet the highest THX standards. Advanced thermal, current, DC,
and speaker protection further guarantee exceptional performance
under even the most extreme operating conditions. Add to this
incredible power and wide-ranging flexibility, and the CX ampli-
fiers are at home in the most sophisticated and demanding home
theaters.
