Infinity Kappa 102a - Features

F E A T U R E S
The Kappa 102a is a 2-channel power amplifier that offers stereo, bridged-mono,
or tri-mode operation, and is rated at 100 watts (rms) per channel into a 4-ohm
load. In a bridged-mono configuration, it can deliver up to 300 watts (rms) for the
same load. The 102a also features:
• 2-ohm operation, rated at 150 watts (rms) per channel
• A bridge/stereo switch for fast system setup
• A built-in 12 dB-per-octave electronic crossover, variable from 32 to 320 Hz
• Dynamic Bass Optimizer™ (DBO) 12 dB-per-octave subsonic filter with
variable frequency (20 to 80 Hz) and Q for enhancing low frequencies while
conserving amplifier power
• Individually selectable high- and low-pass filters (with through-pass) for
amplifier and auxiliary outputs
• An amplifier input sensitivity control to match a wide range of input signal
levels from 250 mV to 9 V
• Five protection levels guard against over-voltage, under-voltage, over-power,
over-temperature, and over-current situations
• 2-color LED array indicates green when power is on and orange when
protection is activated
• Industrial-grade, gold-plated, “pre-wire and plug-in” connectors for an easy-to-
install high-quality interface
• Transparent control cover to deter tampering yet provide a clear view of
installation settings
• Built-in automotive type fuse to protect the amplifier
• Unibloc™ chassis provides improved heat-sink capacity and exceptional RFI
shielding characteristics
