Klipsch KA-1000-THX THX Ultra2 Subwoofer Amplifier

Designed exclusively for use with Klipsch
KW-120-THX subwoofers, the KA-1000-THX
is a THX Ultra2 certified monoblock power
amplifier capable of 500 watts continuous
output into 8 ohms (a single KW-120-THX
subwoofer, for example) or 1,000 watts
continuous into 4 ohms (two parallelconnected
KW-120-THXs). It incorporates
front-panel controls for level, crossover
frequency, phase, and room-gain compensation.
The crossover can be bypassed to feed the
amplifier directly from the subwoofer output
of an A/V preamplifier, processor, or receiver.
Line-level input and output connections are via
gold-plated left/right RCA jacks. The amplifier
has two parallel-wired speaker outputs with
NL2 SpeakOn™ jacks for correct, secure cable
connections.
Convenience features include a selectable
signal-sensing auto-on/off circuit, a front-panel
main power switch and LED status indicators
for crossover and level control operation.
Matching the look of Aragon home-theater
components, the KA-1000-THX has a blackanodized,
grained-aluminum front panel with
aluminum control knobs. Premium electronic
components are used throughout for sonic
purity and reliability.
