Harman Kardon CA140Q User Manual

30 Amperes of HCC (High Instantaneous Current Capabil-
ity) maintains a wide dynamic range and low distortion when
driving low impedance or reactive loads.
High Power Output of 35 watts per channel into 4 Ohms, 35
watts per channel into 2 Ohms and 70 watts bridged into 4
Ohms.
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 with only 25dB
of negative feedback. This further improves dynamic accu-
racy.
Discrete Component Audio Circuitry is used because it was
found to be the only way to provide HCC, Ultrawide Band-
width and Low Negative Feedback.
A High Capacity Power Supply enables stable operating
voltages even under high power conditions. This results in
improved low frequency sound quality.
@ High Heat Dissipation Capability is provided by a large
heatsink, efficient circuitry and rugged circuit components.
Protection Circuitry assures reliability under high tempera-
ture, reverse-voltage and short-circuit conditions, without
degrading the sound quality during normal high power
operation.
Simultaneous Stereo/Bridged Operation provides operating
flexibility, system simplicity and added value.
Be sure that metal objects or other foreign materials do not
enter the unit. This can cause immediate trouble or reduce
the unit’s long-term reliability.
it is natural for this unit to become warm while operating. It
incorporates thermal protection circuitry to shut off the unit
when operating abnormally.
lt is recommended that this unit be operated in a vehicle
only while 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-circuited speakers or speaker wires. When this
protection circuitry is momentarily activated, the power out-
put is muted for several seconds and is then restored. When
the terminals are continuously short-circuited, the power
output will remain muted. Should the latter occur, shut off
the unit and check the speakers and speaker wires.
The heat generated by this amplifier is dissipated into the air
by the entire chassis. If it is covered, or becomes dirty so
that the circulation of the air 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 provide uninterrupted operation. However,
when full power is drawn in an already hot environment, any
loss in heat dissipating capability is likely to result in activat-
ing the thermal protection circuits.
When replacing the fuse, be sure to use an identical value
(CA140Q: 30 ampere, CA70: 15 ampere) auto fuse.
lf your unit behaves abnormally, turn it off immediately and
consult an authorized Harman Kardon Service Station.
