2-DIN Chassis: The Clarion CX501 has a 2-DIN chassis (also
known as "Double DIN" or size DD), and will fit in many vehicles with a large
dash opening. The unit can be ISO-mounted using your vehicle's factory radio
brackets and the supplied hardware. There is also an optional custom double-DIN
sold separately) available for this unit that will allow you to mount the CX501
in a custom 4" opening. As always, please consult the
Crutchfield Car Selector to verify fit with your vehicle.
728-Variable Color Illumination: The CX501 is equipped with a high
visibility, 728 Variable-Color Illumination LCD that allows numbers and
characters to be displayed clearly in all lighting conditions. You can select
the exact color you want for the head unit's display and button illumination to
match your car's instrument panel or personal preference. You can adjust the
display contrast to match the angle of installation of this unit between 1 to
Large Rotary Control Knob: The unit's large 3-way rotary control knob,
combined with the ergonomically symmetrical design of the unit, helps to provide
equally comfortable operation from the driver side or passenger side. Its
intuitiveness and natural feel minimizes stress for the operator and contributes
to driving safety.
Illumination Dimmer: The
receiver's display automatically dims to a preset brightness when the vehicle's
headlights are turned on. The wiring harness includes an orange/white lead that
should be connected to the vehicle's parking light circuit in order for the
dimmer feature to operate.
Screen Saver: This unit is provided with a Screen Saver function which
allows you to show various kinds of patterns and characters in the operation
status indication area of the display in a random order. You can turn this
function on or off. If the button operation is performed with the screen saver
function "On", the operation display corresponding to the button operation is
shown for about 30 seconds and then the display returns to the screen saver display.
Anti-Theft System: Since the CX501 does not have detachable
face, this unit features Clarion's Anti-Theft System (CATS). CATS allows you to
create a 4-digit code that must be entered to operate the unit if it is ever
disconnected from your vehicle's battery.
Anti-Theft Indicator: The red Anti-theft indicator on the
unit's front-panel is a function for preventing theft. When the CX501 and your
vehicle is turned completely off, this indicator will blink to deter theft.
MOSFET Amplifier: The Clarion CX501 is equipped with a
MOSFET amplifier. 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. More
power means louder and cleaner music at higher volumes because you're not
pushing the limits of the amplification circuit.
CEA2006 Compliant: The power specifications for the CX501
are compliant with the CEA2006 Mobile Amplifier Power Testing and Measurement
standards from the Consumer Electronics Association (CEA). These standards were
developed as a way to equitably compare power specs from model to model and
between manufacturers. The power output specs for the CX501 are as follows:
- CEA2006 Specs: 21 watts RMS x 4 channels (at 4 ohms,
20Hz-20kHz, 1% THD-N)
- Maximum Power Output: 50 watts x 4 channels (180 watts
BeatEQ: In addition to providing 3 preset equalization
patterns (Bass Boost, Impact, and Excite), Clarion's BeatEQ lets you freely
customize the level and range of the bass, midrange and treble portions of each
pattern. You can tune the sound to your liking, depending on the category of
music, for a more fulfilling listening experience.
- Bass Boost: Bass is emphasized +/-3.
- Impact: Bass and treble are emphasized +/-3.
- Excite: Bass, midrange, and treble are emphasized +/-3.
- Custom: Adjusts the bass, midrange, and treble
- Bass: You can set the effected bass frequency to
50Hz, 100Hz, or 200Hz and the Q-factor to 0.7, 1, 1.4, or 2
- Midrange: You can set the effected midrange
frequency to 500Hz, 1.0kHz, or 2.0kHz and the Q-factor to 0.7, 1, 1.4,
- Treble: The effected treble frequency can be set to
5kHz, 10kHz, or 15kHz, and the Q-factor to 0.7, 1, 1.4, or 2
- Off (Flat): Bass, midrange, and treble are set to 0.
Magna Bass EX (Extend): The Magna Bass Extend feature does not adjust
the low frequencies like the normal sound adjustment function, but emphasizes
the deep bass frequencies to provide you with a dynamic sound. This circuit
boosts bass at an ultra-low frequency of about 50Hz, creating a rich, deep,
defined bass rather than the muddy, booming bass of a standard loudness control.
What is more, boost levels are dependent on the system volume, resulting in
balanced system response and dynamic bass reproduction.
6ch/4V RCA Output: The Clarion CX501 features 6ch/4V RCA
line level outputs (Front/Rear/Sub). The head unit is able to connect a full
range of speakers, ranging from tweeter and mid-range to subwoofers. The full
set of line outputs allows integration into a wide range of potential systems,
and is ready to support future system expansions.
Subwoofer Controls: The non-fading subwoofer preamp output
features an independent level control (+/-6) and phase adjustment
Built-in Crossovers: The Clarion CX501 is equipped with
built-in low-pass and high-pass crossovers.
- Low-Pass Subwoofer Filter: The Low-Pass Filter (LPF) for
the subwoofer preamp output (when activated) will send only the low frequency
range through the preamp outputs to ensure superb performance with a connected
subwoofer. The low-pass filter can be set to 60Hz, 90Hz, 120Hz, or Through
- High-Pass Filter: The CX501 features a High-Pass Filter (HPF) for
the unit's front & rear channels, via speaker-output or preamp-output. You
can adjust the high-pass filter from 60Hz, 90Hz, 120Hz, or Through
(full-range). The HPF prevents low bass notes from distorting your front & rear
speakers. The high-pass filter setting effects both the front & rear
channels of the head unit.
Beep: The in-dash head unit provides an audible beep to
confirm button operation. This function can be turned On or Off.
AM/FM Tuner: The Clarion CX501 is equipped with a built-in AM/FM
tuner offering 18 FM station presets and 6 AM station presets. Stations can be stored

stations with strong radio signal can be received.
HD Radio Ready: With an optional Clarion THD301 HD Radio
tuner (020THD301, sold separately), you will be able to receive digital AM/FM
broadcasts from local stations where available. This new technology will
significantly improve audio quality and reception, as well as include
information such as artist name and song titles or traffic news, viewable on the
receiver's display. The add-on HD Radio tuner includes iTunes Tagging
capability, so if you hear a song on the radio that you like, you can tag it to
download later from the iTunes Store.
