Tips How To Optimize Honda HR-V Audio Device
kanjenkautomotive.blogspot.com - Honda
HR-V became the model Crossover Utility Vehicle (CUV) first Honda in Indonesia,
which was first introduced in Indonesia International Motor Show (IIMS) 2014
ago. As one of the spearheads sales of Honda models, they offer Honda HR-V with
many features, including treats entertainment features (audio) are qualified.
As to whether the audio quality is presented? To prove pemanja ear Honda HR-V
1.8 Prestige, we took it to Afung, fitter Mobiltronik at Jl. Metro Indah Raya
Blok A3 No.12-14 Sunter, North Jakarta.
Features
At
the highest variance HR-V, have been immersed Head Unit (HU) 7035BT Kenwood
DDX-type, which is HU double-DIN DVD Multimedia AV Receiver which features a
7-inch LED screen VGA Touch Display as the control center of a variety of
entertainment in the car. Audio devices using the Advanced Audio Video System
compatible with various music formats through media such as AM / FM radio, CD /
DVD player, MP3 / WMA, iPod / iPhone / Android, USB port and HDMI port are in
the glove box, and can connected with AUPEO for Radio Streaming application on
the smartphone.
Special
features of the audio sector ie there are seven band equalizer, subwoofer
output, select speakers, subwoofer level, a digital sound processor, speaker
positioning, digital time alignment, display off mode, back-up camera input and
drive equali¬zer to improve fre-kuensi low when the vehicle is moving.
"There is a menu drive equalizer to boost lower frequencies as the
compensation of road noise. When the vehicle is moving, road noise will disturb
fre¬kuensi low, so that the automatic frequency increased, "said Afung.
Tonal Balance
In
order to assess the quality of the audio system bursts HR-V, Afung using a Real
Time Analyzer (RTA) without meng¬ubah audio factory default settings. When the
pink noise testing, all levels of frequency and the other is the zero position
(0) and drives the equalizer remain menyala.Sebagai standard assessment
measures, some music coming from CD EMMA also rotated.
At
the time of trial pink noise, the results can be seen from the graph there is a
shortage. "For equalizer need to be reset at 500Hz and 16KHz frequency
that is somewhat lacking. From the pink noise testing, the chart showed a
decrease in the frequency of 500Hz. I have tried to adjust via the equalizer in
HU, but did not help. There are two kemungkin¬an cause. The first is the
resonance of the door trim or indeed cancel own this car at a frequency of 500
Hz for the position and space, "said Afung, explained de¬ngan
enthusiastic.
Optimization
Data
from the RTA graph also shows that too over mid bass. For that Afung advised to
standard optimization with menurun¬¬kan frequency 62.5 Hz at -1dB, 400Hz
frequency is increased +3 dB, frequency 6.3 KHz increased + 2dB and 5dB
increased frequency of 16KHz. Position tweeter according Afung good enough
because of his position away from the driver's ear. "It should vote on
will be better when a pair of tweeters placed on pillars A, parallel to the
ear," he continued.
Even
so, contour and depth dashboard very good for the development of sound quality
(SQ) 3-way. If consumers want to upgrade custom contour audio then sort it
would be helpful. For optimization, the most basic thing to do is to add a pair
of damper on the door trim.
The
next step is menambahankan slim eight-inch active subwoofer that can be
directly connected de¬ngan HU. Then if not satisfied, consumers can perform the
replacement of the front speakers plus the addition of an external amplifier
processor. Or if you want a more practical, Afung suggest adding a processor
that has built-in amplifier with funding ranging from $ 3 million.
