Kappa 202a

PRECAUTIONS AND NOTES
•The Kappa 202a has five levels of circuit protection
that monitor the amplifier and will shut it down if the
electrical system voltage drops below 10 Vdc or
exceeds 15.5 Vdc, temperatures are above 194°F (90°
C), short circuits occur, or current draw exceeds
product specifications. For best performance, check
the intended mounting site to make sure the
operating environment does not create conditions that
will trigger circuit protection.
•Prior to installation, turn off all audio systems and
other electrical devices. Also disconnect the (–)
negative lead from the vehicle’s battery.
•At the installation site, locate and make a note of all
fuel lines, hydraulic brake lines, and electrical wiring.
Use extreme caution when cutting or drilling in and
around these areas.
•Use the amplifier as a mounting template to mark
locations for the mounting holes.
•Check clearances on both sides of a planned mounting
surface before drilling any holes or installing any
screws. Remember that mounting screws can extend
up to an inch behind the surface.
•Always wear protective eyewear when using tools.
•The Kappa 202a uses gold-plated, industrial-grade
Weco®plug-in connectors for power and speaker
wiring. Because of precision tolerances, do not insert
the connectors into the amplifier without pre-wiring
them first. Once the wires are fastened in each shell,
they provide additional gripping area for easy
connector removal.
•When routing cables, keep input signal cables away
from power cables and output speaker wires, as
shown in Figure 6 (below).
•When making connections, make sure that each
connection is clean and properly secured. Observe the
polarity markings on the rear panel. Refer to the
application drawings (Figures 1 through 3 on page 3)
to set up the amplifier for operation in stereo, bridged-
mono, bi-amp, or tri-mode configurations.
•If the amplifier’s fuse needs replacement, use only
the same rating and type as a replacement. Do not
substitute another kind.

Kappa 202a

INSTALLATION
The Kappa 202a is easy to install. For optimum
performance, we recommend using high-quality, twisted-
pair shielded RCA audio cables and 14-gauge or larger
speaker wire. Also, you’ll need a minimum of 12-gauge
stranded copper wire (e.g., red and black jackets) for the
power connections. Use 18-gauge (e.g., blue jacket) wire
for remote turn-on.
Depending on your total system plan, allow for adequate
time and the possibility of overnight storage of your
vehicle, since it may take more than one day to complete
the installation.
PARTS LIST...
Examine and verify that the package includes the
following items:
•(1) Kappa 202a Power Amplifier
•(2) Spare ATC fast-blow fuses (40 A)
•(1) Control cover with (2) machine screws
•(1) Weco 5-pin audio connector
•(1) Weco 2-pin power connector
•(4) #8 mounting screws
MOUNTING THE AMPLIFIER...
The Kappa 202a can be mounted in virtually any location
inside the vehicle. However, make sure to keep the
amplifier away from heater vents or ducts.
1. At the chosen site, use the amplifier as a mounting
template and mark locations of the four mounting holes.
2. Drill a small pilot hole at each marked location.
3. Mount the amplifier and securely tighten the
mounting screws.
WIRING THE AMPLIFIER...
Refer to Figure 7 (below) for details of the Kappa 202a’s
front and rear panel connections.
1. For power, remote, and speaker wires, strip 1⁄4" off
one end of each jacket to reveal bare wire for insertion
into the Weco connectors.
2. Using the Weco 2-pin power connectors, connect
individual black wires from the nearest bare-metal
chassis component to each (–) terminal. Then, connect
individual red wires from the vehicle’s +12-volt
battery terminal to each (+) terminal.

INSTALLATION (continued)
3. Make sure the wires are firmly seated in each Weco
2-pin connector and that each screw is completely
tightened. Insert the wired connectors into the POWER
sockets on the amplifier. Press each one in until it stops.
4. Using the Weco 5-pin connector, connect a blue wire
from the source unit’s remote connection to the REM
terminal. Depending on polarity requirements (e.g.,
bridged-mono or tri-mode configurations –see Figures
1 through 3 on page 3), connect speaker wires from
the speakers to the L and R (+ and –) terminals, as
required by your system plan.
5. Make sure the wires are firmly seated in the Weco 5-pin
connector and that each screw is completely tightened.
Insert the wired Weco 5-pin connector into the 5-pin
socket on the amplifier. Press it in until it stops.
6. Connect RCA cables from a source unit to the L and R
INPUT jacks.
SETTING THE CROSSOVER...
IMPORTANT: If you plan to use the Kappa 202a to drive
full-range speakers, set both AMP and AUX filters to
FLAT (refer to Figure 1 on page 3 and Figure 8 below)
and skip to the next section, “Setting Input Sensitivity”.
1. Set the CROSSOVER control to the frequency
recommended by speaker manufacturer (refer to Figure
8). If the value is unknown, set the control midway.
Figure 8. Kappa 202a controls for crossover, input, output, and
DBO (Dynamic Bass Optimizer).
2. Depending on your system plan, set the AMP and
AUX switches to LP (low-pass), HP (high-pass), or
FLAT (refer to Figure 8).
SETTING INPUT SENSITIVITY...
Initially, turn the input sensitivity GAIN control to its
minimum (counter-clockwise) position (refer to Figure 8).
1. Reconnect the (–) negative lead to your vehicle’s
battery. Apply power to the audio system and play a
favorite music track from CD or tape.
NOTE: After the source unit is on, green LEDs (on the top
pane)l will illuminate, indicating the amplifier is on. If not,
check the wiring, especially the remote connection from the
source unit. Also refer to “Troubleshooting”on the next page.
2. On the source unit, increase the volume control to
maximum position. Slowly increase the GAIN control
(clockwise) towards three o’clock and, at the same
time, listen to the quality of the reproduced sound. At
some point, you’ll hear distortion on the music peaks.
Stop the adjustment and turn it back slightly.
SETTING DBO...
Dynamic Bass Optimizer (DBO) is a new approach to
enhancing low-frequency reproduction in a vehicle.
Conventional bass boost controls add bass at a fixed
frequency and cause the amplifier to consume
considerable power. DBO conserves valuable power at
the lowest frequencies and allows you to adjust the level
and “character”of the bass sound, instead of just the
amount of boom.
Since a subwoofer in a tuned box is given to overexcursion
below the tuned frequency, set the FREQ control below
the box’s resonant (tuned) frequency (see Figure 9 on the
next page). Power typically wasted in this region will now
be conserved and instead be available for frequencies the
enclosure will reproduce. Use the Q control to boost the
bass at the set frequency by as much as 12 dB (at MAX
position –see Figure 9 on the next page).
For sealed enclosures, use DBO to enhance the output so
it sounds more like a tuned box. This is a result of 12 dB
of rolloff being added to the enclosure’s rolloff and a
flattening of frequency response (at the curve’s knee)
when Q is boosted.
For infinite baffles, set the FREQ control to the speaker’s
Fsvalue (to keep the subwoofer from trying to create bass
below the resonant frequency) and adjust the Q control
according to personal taste.
INSTALLING THE CONTROL COVER...
After wiring and testing the Kappa 202a amplifier, install
the control cover using the enclosed machine screws to
deter tampering and help seal out dust.
NOTE: Do not over-tighten the machine screws. Doing so may
crack the cover.
