Harman kardon CA260 OWNER’S MANUAL
Congratulations on your purchase of a Harman Kardon CA260
High Fidelity Car Amplifier.
The CA260 is the result of an extensive engineering project
to create the finest automotive high fidelity product available.
It
is superior in performance and has the ability to operate under
extreme environmental conditions.
To fully understand the CA260's capability, please read this
manual carefully and follow all of the instructions regarding its
use and installation.

30 Amperes of HCC (High Instantaneous Current Capab~lity) ma~nta~ns a

Ultrawide Bandwidth is achieved by the use of inherently fast open-loop
circuitry This improves transient accuracy and phase
linearity
Low Negative Feedback
Highly linear circuitry produces low
distortion
w~th only 25dB of negative feed-
back. Thls further improves dynamic accuracy.
Discrete Component Audio
Circuitry
is used because ~t was found to be
the only way to provide HCC, Ultrawide Bandwidth and Low Negarive
Feedback.
H~gh Capacity Power Supply
Two 10,000pF capacitors, six 80 watt switching transistors, and a sophisticated transformer coil design enable stable operating voltages even under
h~gh power conditions. This results In lmproved low frequency sound quality.
High Heat Diss~pat~on Capability is provided by a large heatsink, efficient
circuitry and rugged circuit components
Protection Circuitry assures high reliability under high temperature, overvoltage, reverse-voltage and short-circuit conditions, without degrading the
sound quality during normal high power operation. When the internal tem-
IS
perature reaches 175" F (80' C), the maximum output power
reduced,
which In turn reduces the operating temperature
Built-in Active Crossover and Bridged-mono features prov~de operating flexibility, system s~mplicity and added value.
Be sure that metal objects or other fore~gn mater~als do not enter the unlt
This can cause immediate trouble or reduce the unit's long-term reliability.
IS
natural for thls unlt to become warm whlle
It
operating
It ~ncorporates
two thermal protection circuits: One to prevent excessive temperatures from
being developed under normal operation, and another to shut off the unit
when operating abnormally When the thermal protection system is operatmg, the amber mdcator wdl illuminate
It is recommended that th~s unlt be operated in a vehcle only whde the
engine (and electrical charging system) is running. At high power output,
it typically draws about as much current as an automobile's headlights, and
therefore can eventually discharge the battery.
The speaker output terminals are protected from damage due to short-cir-
IS
cuited speakers or speaker wires. When this protection circuitry
IS
tarlly actlvlated, the power output
muted for several seconds and is then
momen-
restored. When the terminals are continuously short-circuited, the power output w~ll remaln muted Should the latter occur, shut off the unit and check
the speakers and speaker wires.
The heat generated by this amplif~er is dissipated into the alr by the entire
chassls If it
IS
covered, or becomes d~rty so that the clrculatlon of the alr
around it is reduced, the unit's ability to dissipate heat will also be reduced.
Under most conditions, the heat dissipating capability of this unit is more
than enough to provlde uninterrupted operation However, when full power
is drawn in an already hot environment, any loss in heat dissipating capability
is likely to result in activating one of the thermal protection circuits
Th~s unlt uses a 30 ampere auto fuse
When replacing the fuse, be sure to use
an identical 30 ampere (green) auto fuse.
To replace the fuse, remove the cover by
pushing down on the top of the fuse
cover Use the spare fuse which is stored
above In the fuse compartment.
If your unit behaves abnormally, turn it off immediately and consult an
authorized Harman Kardon Service Station
