KAPPA 202A POWER AMPLIFIER
The Kappa 202a is a member of Infinity’s new Kappa
series of mobile power amplifiers. Housed within the
sleek, extruded aluminum frame, you’ll find the latest
advances in circuit topology, along with user
conveniences like a wide-range input sensitivity control,
auxiliary outputs, and a built-in electronic crossover.
With features like these and more, you can quickly try
out a variety of system ideas, and because the Kappa
202a belongs to a related product family, you’re assured
future expansion will look as good as it sounds.

The Kappa 202a is a 2-channel power amplifier that offers
stereo, bridged-mono, or tri-mode operation, and is rated
at 200 watts (rms) per channel into a 4-ohm load. In a
bridged-mono configuration, it can deliver up to 600 watts
(rms) for the same load. The 202a also features:
•2-ohm operation, rated at 300 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
•Separate power supplies for each channel
•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 fuses to protect the amplifier
• ™Unibloc chassis provides improved heat-sink
capacity and exceptional RFI shielding characteristics
