MOSFET Switching Power Supply: The Kenwood KAC-7205
Two-Channel amplifier is equipped with a MOSFET switching power supply. Compared
to conventional power supplies, the MOSFET amplification circuit is
smaller and more efficient, and it delivers increased power with less distortion
and absolutely zero on/off switching noise.
CEA 2006 Compliant: The KAC-7205's power ratings are
measured according to the strict standards dictated by the Consumer Electronics
Association (CEA). These standards allow you to accurately compare the rated
power output of all CEA 2006-compliant amplifiers, even if they come from
different brands. Manufacturers who adhere to the standards can display the CEA
2006 logo on their products and packaging.
Amplifier Rating: The Kenwood KAC-7205 two-channel amplifier is
bridgeable (4-ohm), as well as 2-ohm stable in stereo.
- Two-Channel (CEA 2006 Compliant): 170 watts x
2 channel RMS @ 4 ohms (20 Hz-20 kHz, 1% THD)
- Two-Channel (2-ohm): 250 watts x 2 channel RMS (1 kHz, 0.08% THD)
- Bridged (4-ohm):
500 watts x 1 channel RMS (1 kHz, 0.08% THD)
- Peak Power: 500 watts
x 2 channel (1,000 watts total max power)
Cast Aluminum Heat Sink:
The Kenwood KAC7205 utilizes a cast aluminum heat sink design to ensure
that the amplifier stays at its optimal temperature.
Fan Cooled: The KAC-7205 is equipped with two, rear
panel-mounted cooling fans. One fan acts as an intake while the other serves as
an exhaust to create a current of cooling air flowing through the inside of the
The amplifier features protection circuits that will turn the amp off in case of
the following events:
- Speaker output contacts ground
Speaker wire short-circuits
Unit malfunctions and DC is sent to
Aluminum Cover Plate: The amplifier's controls and connections are
hidden under a removable extruded aluminum cover plate. The cover plate provides
a professional looking installing while helping to protect the amplifier's
connections and control settings.
Blue/Red Illumination: The Kenwood two-channel amplifier features a
blue and red LED illumination when the amplifier is turned on.
Signal-sensing Turn-On Circuitry: When the speaker-level
input is used, it is not necessary to connect the power control wire (turn-on
lead). The amplifier senses the signal from the speaker-level input and turns
the amplifier power on automatically. Shortly after no signal is detected, the
amplifier will automatically shut itself off.
accommodate the varying range of signal levels coming from today's factory and
aftermarket radios, the Kenwood KAC-7205 features an adjustable gain control
(0.2-5.0V). This means that no matter what kind of radio is connected to this
amplifier, the appropriate gain control adjustment can be made to ensure loud,
clear, distortion-free music.
Low Pass Crossover (LPF): The Kenwood KAC-7205 is equipped
with a variable low-pass crossover (24 dB/oct). The amplifier has a two-way filter switch,
allowing you to choose low-pass (LPF) or full-range (Filter
Off) operation. There is a rotary control for the Low Pass cutoff
frequency, allowing you to set the LPF between 50 to 200 Hz.
Bass Boost: You can apply a bass boost of up to +18dB at
Power Connections: The power and ground connections are 0.5625" wide screw terminals that
will accommodate up to 4-gauge wire. The remote turn-on terminal is 0.3125" wide
and will accept up to 8-gauge wire. A Phillips-head or flat blade screw driver
(not supplied) is required to tighten/loosen the terminals. Spade connectors are
recommended for the power, ground, and remote wires.
Speaker Outputs: The Kenwood KAC-7205 is equipped with two
pair of speaker terminals. All four speaker terminals are 0.3125" wide
screw terminals and will accommodate up to 8-gauge wire. A Phillips-head or flat
blade screw driver (not supplied) is required to tighten/loosen the terminals.
Spade connectors are recommended for the speaker wires.
Note: The speaker output terminals can be used in stereo or
Line Level Input: The two-channel amplifier is equipped with a pair of gold-plated RCA line level
Speaker Level Input: The
KAC-7205 comes with a two channel speaker level input harness. Once you splice
the speaker wires from the receiver to the harness, you have
plug-in convenience to the amplifier. This feature makes it easier to add an
amplifier to a factory radio or to a receiver with no preamp outputs. The maximum
power output from the source receiver can be no more than 40 watts.
Fuses: The KAC-7205 is equipped with two 30 amp ATO blade fuses.
