Dual Auxiliary Inputs
Dual Auxiliary Inputs: A front-panel & rear-panel stereo minijack
are provided to allow the connection of portable
audio sources. Simply connect your portable digital music player to either
the unit's front or rear auxiliary input, and you can listen to the audio from the portable player through the
speakers in your mobile audio system.
Simultaneous Connection: The front-panel & rear-panel auxiliary
connections are separate (independent) inputs, so you can connect two portable
audio devices at once to the JVC head unit and select between sources. You can turn the front- and rear-panel auxiliary inputs On
Optional Bluetooth: The
unit's rear-panel auxiliary input can also be used to connect JVC's KS-BTA100
Bluetooth Adapter (105KSBTA10, sold separately).
The KS-BTA100 must be plugged into the rear-panel auxiliary input, and not
the front-panel auxiliary input. The front-panel auxiliary input does not
support Bluetooth. The KS-BTA100 gives
you hands-free communication from your compatible Bluetooth mobile phone and
wireless streaming audio from a Bluetooth enabled digital audio player. The
optional JVC Bluetooth Adapter includes a super-sensitive microphone, an
Answer/End button, and playback controls. The KD-X40 can be set to
automatically mute any music audio to your vehicle's speakers so you can listen
to your telephone call using your car speakers.
Note: Not all Bluetooth devices will be compatible.

presets and 6 AM station presets. The radio allows you to set your AM/FM
stations manually or automatically.
Radio Timer: You can tune into a preset station at a specific time
regardless of the head unit's current source. You can activate the Radio Timer
once, daily, or turn it completely off.
IF Filter: You can also switch the tuner's IF filter to Wide
or Auto to increase/decrease the sensitivity.
Mono: If an analog FM stereo broadcast is hard to receive, you can
manually switch the tuner to Mono operation.
US/European Tuning: You can set the built-in AM/FM tuner
between US standard and European tuning spacing.
24 Bit D/A Converter: The JVC KD-X40 utilizes a 24-bit
digital to analog converter for superior sound quality.
MOSFET Amplifier: The KD-X40 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
CEA2006 Compliant: The power specifications for the KD-X40
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 KD-X40 are as follows:
- CEA2006 Specs: 20 watts RMS x 4 channels (at 4 ohms,
20Hz-20kHz, 1% THD-N)
- Maximum Power Output: 50 watts x 4 channels (200 total
Amplifier Gain Control: When you
are using the KD-X40 with factory speakers (or those rated to less than 50
watts peak), the Amplifier Gain Control can limit the amount of power being sent
to those speakers. When the Amp Gain Control is set to "low," the volume control
ranges from 0 (minimum) to 30 (maximum). When using speakers rated higher than
50 watts peak, you can set the Amp Gain Control to "high," and the volume
control will range from 0 to 50.
Volume Adjust: The input level of each source (other than FM) is
adjustable relative to the FM radio volume, so there isn't a significant volume
difference when changing sources. Each source is individually adjustable from -5
Pro EQ: The KD-X40 is equipped with JVC's Pro EQ. The
integrated equalizer offers 7 preset sound modes (Flat, Natural, Dynamic, Vocal Boost, Bass Boost, User) suitable for the music genre of your choice. The User mode allows you to manually adjust the head unit's 3-band parametric EQ
(Frequency, Level, and Q-Factor).
| Pro EQ |
| Frequency || Level || Q |
| Bass ||60, 80, 100, 200 Hz ||+/- 12 dB (-6 to +6) ||1.0, 1.25, 1.5, 2.0 |
| Midrange || 0.5, 1.0, 1.5, 2.5
kHz || +/- 12 dB (-6 to
+6) || 0.75, 1.0, 1.25 |
| Treble ||10.0, 12.5, 15.0, 17.5
khz ||+/- 12 dB (-6 to +6) ||Fixed |
Source Link EQ: This feature allows you to store Pro EQ
bass, middle and treble tone settings for each source (AM/FM, Aux, USB, iPod,
Loud (Loudness): This feature boosts low and high frequencies to produce a well-balanced sound at a low volume
level. You can turn this feature on or off.
2.5V/4CH Preamp Output: The KD-X40
is equipped with two pair of 2.5V preamp outputs (Front, Rear/SW). You can set the Rear/SW preamp outputs for connecting
a pair of full-range rear speakers (through an external amplifier) or for connecting a subwoofer (through an external
amplifier). When set for rear speakers, the rear outputs operate with the unit's
fader control. When set for subwoofer, the outputs are non-fading.
Subwoofer Controls: When the unit's Rear/SW preamp output is set to
Subwoofer, you can adjust the head unit's subwoofer level between 0 to 8
(separate from the main volume level). You can also adjust the low-pass filter
and activate a high-pass filter.
- Low-Pass Filter: When the unit's Rear/SW preamp output is set to
Subwoofer, you can
set the cutoff frequency of the low-pass filter at 55Hz, 85Hz, or 120Hz.
- High-Pass Filter: When the unit's Rear/SW preamp output
is set to Subwoofer, you can also activate a high-pass filter (fixed at
low-pass filter frequency) for
the unit's front & rear channels (speaker- or preamp-level), so low frequency signals are cut
off from your system's front & rear speakers.
Key-Touch Tone: The in-dash head unit provides an audible
beep to confirm button operation. This function can be turned On or Off.
Variable Color LCD & Key Illumination: The JVC KD-X40
features 29 color presets for the LCD and button illumination. You can choose
one of these color presets or select the ColorFlow mode which scrolls through
all 29 color presets. Additionally, there is a User preset, allowing you to
individually adjust the intensity of Red, Green, and Blue from 0 to 31;
resulting in approximately 30,000 custom color options. The chosen color preset
or custom color can be applied to the display panel and the backlighting for all
You can choose to use the same color for the LCD display and button
illumination, or use a separate color for each one. You can also select a
different color for daytime and nighttime in regards to the unit's LCD and
Brightness: The unit offers an adjustable display and button
illumination brightness level (0-31) for day and nighttime driving.
Display/Button Illumination Dimmer: The display/button
illumination dimmer can be set to Off (normal brightness at all times), On
(display/button illumination is always dimmed), or Auto (display dims when
12-volts is applied to the orange/white illumination lead).
Mounting Angle: For proper operation, you must install the
unit within 30-degrees of horizontal.
Wireless Remote Control: The
KD-X40 comes supplied with a wireless remote control (RM-RK52). The remote
contains Attenuator, Sound, Source, Tracking, and Volume functions. The
remote operates off of a single CR2025 3V Lithium-cell battery (included).
Steering Wheel Remote Compatibility: The head unit features
an OEM steering wheel remote control input wire (blue/yellow) within the
included wiring harness that lets you keep your vehicle's factory radio steering
wheel remote controls when used with an optional
steering wheel audio control adapter (sold separately). Please consult
Outfit My Car to see if your vehicle is compatible.
