Audio Section
24 Bit D/A Converter: The JVC KW-AVX840 utilizes a 24-bit
digital to analog converter for superior sound quality.
MOSFET Amplifier: The KW-AVX840 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 KW-AVX840
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 KW-AVX840 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
watts)
Amplifier Gain Control:
When you are using the KW-AVX840 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. The internal amp can also be turned
off when all the speakers are powered by outboard amplifiers.
5ch/4V Preamp Outputs: The KW-AVX840 is equipped with
5ch/4.0V preamp outputs (Front, Rear, Subwoofer). The front and rear preamp
outputs allow fader control, while the subwoofer preamp output is non-fading.
Subwoofer Controls: You can adjust the KW-AVX840's subwoofer
level (-50 to +10) independently from the head unit's main volume control for
added bass volume. You can also adjust the subwoofer phase between Normal or
Reverse to blend the bass sound better with the rest of the speakers in
your system.
Built-in Crossovers: The JVC KW-AVX840 features a built-in
high-pass filter for the unit's front & rear speakers, and a low-pass filter for
the unit's subwoofer output.
- High-Pass Filter: You can activate a variable high-pass
filter (40, 60, 80, 100, 120, 150, 180, 220 Hz or Through) 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. The front & rear
channel's high-pass filters can be set independently of one another.
- Low-Pass Filter: The unit's subwoofer preamp output
features a low-pass filter. In order to prevent high-frequencies from being
sent to your system's subwoofers, you can set the cutoff frequency of the
low-pass filter to 50, 60, 80, 100, 120 Hz or Through.
Speaker Select: You can
select which type & size of speaker you have connected to the head unit. Choose
from Standard (OEM/Factory), Narrow (4"/5"), Middle (6"/5x7"/6x8"), Wide (6x9").
Pro EQ: The KW-AVX840 is equipped with JVC's Pro EQ. The
integrated equalizer offers 8 preset sound modes (Flat, Natural, Dynamic, Vocal
Boost, Bass Boost, Vibrant, and 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).
