Optimizing Your Standard Audio System Of Mazda CX-5
Facelift model SUV Mazda CX-5
launched PT Mazda Motor Indonesia, with a focus on changes in the exterior
design and the addition of safety features. In the entertainment device, the
audio system used is a BOSE premium product alerts.
Well, to know the quality of the
audio, we went to Eddie Susanto, fitter Cartens Autosound at Jl. Fatmawati,
Pusat Niaga Duta Mas Fatmawati Blok D2 No. 22, to assess the quality of the
audio system Mazda CX-5.
Features
New Mazda CX-5 has a head unit (HU)
seven-inch touch screen, where fumgsi the touch screen will not work if the car
is moving. The audio system is named MZD Connect that can be controlled via the
control center close to the middle console arm rest.
With Bluetooth technology, you can
also enjoy streaming audio and internet radio with hands-free and voice command
that can be connected to smart phones. Nine speakers from BOSE ready to sing
the voice indulgent ear. HU seven inches was capable of playing music
originating from DVD, CD, MP3, WAV, radio, USB, Bluetooth, wifi, and can also
be connected to the Aux, and available audio steering control switches on the
steering wheel to operate the audio system functions.
Tonal
Balance
To determine the voice quality
testing is done using the application devices RTA (Real Time Analizer) from
iPad to display the frequency spectrum. With tonal balance in the zero
position, the testing is done by using pink noise. "To test the ability of
audio, we use a CD of EASCA, with the volume level 38, the center point off.
Well, the function of the center point of this is to raise the center
frequency, so that the impression of the vocal sounds become louder,
"Eddie said.
"From the test results pink
noise, visible chart fairly flat frequency response in the mid-low dominant. So
the impression vocals thicker and somewhat nge-bass. For harmonization in the
upper frequency slightly down because of the position of the tweeter facing up
and bounced off the windshield. Should have a good tweeter position is parallel
to the ear. But about the depth, quality dashboards and materials have actually
been good, "he continued.
From the pink noise test, according
to Eddi graph is pretty average, if it occurs at a frequency of plus and minus
3 dB to 6 dB is not a problem. But for the mid-high frequencies lacking balance
with bass frequencies.
Optimization
Audio features are very limited to
no control treble and bass only. Even for preset equalizer was not held.
"For the day, the bass could be lowered at -3 or -4. But for the music
sound the dominant vocals can be lowered at -6 bass and treble controls remain
at +2 and the center point is turned on, "Eddie advice.
If users want to upgrade CX-5 audio
and without compromising the system of the head unit, then Eddie suggested to
replace the speaker, power amplifier and subwoofer with funds of around Rp 15
million. However, if only add audio processor only for time correction and the
time delay is not a problem. The addition of a damper on the door trim is also
need for better audio bursts.
"Overall assessment for the
audio Mazda CX-5, which has been supported by a BOSE audio system is good. For
supporting daily activities will suffice. However, sometimes there are also
consumers who want to require detailed sound audio upgrade, "he concluded.
