Audio Treatment: Low Budget
Car Audio November 30th, 2010
need passive2Sistem audio-grade, so that the resulting sound better. There are various methods of up-grade system. Replace products ranging from audio, add voice support to device acoustic treatment.
Well if SO’mers still “kepentok” budget because the pockets had been gone for a new year holiday. I think adding a special device to sound “maknyus”, with affordable prices, could be SO’mers solution.
Idol Audio Workshop has prepared a special device that is:
Copper made in Germany, rather than ordinary copper. Copper made in Germany has a perfect quality. Copper is used for treatment pasive crossover, which is available in the system speakers. Ask your installer recommendations so the results to your liking.
Copper terrsedia various sizes ranging from 0.32 mH to 2.17 mH
Price
German copper sizes under 1mH: Rp 50.000, – (1 winding coil)
German Copper 1-2mH size: Rp 75.000, – (1 winding coil)
German copper sizes above 2mH: Rp 90.000, – (1 winding coil)
Meanwhile, if the audio is less clear, try to pair this one product, Storing Anti-shaped box with a label EMI Filters Jones. This product has 50 amps of power.
The way treatment is very easy, just connect the two poles (+) and (-) on a cable connection from the car battery (batteries) and anti-storing poles on the other side are distributed by cable to the power (amplifier). Feel bedannya, sounds more calm and sounded more cool….
Judging Contests Audio: Understanding Sound Quality Score Sheet
Car Audio November 9th, 2010
This article I found while following fudge EMMA Training in Malaysia last year, a very valuable information from the neighbor country, I pour in www.SitusOtomotif.com eMagazine pages. In my first meeting with readers, I want the score sheet of information about Sound Quality (SQ). (Please note that I write is based on my understanding and recollection simply just to share what I know, not to teach or intend to others).
To understand the Score Sheet sound Quality (SQ) is not required short time. The problem is for beginners pengatahuan it should be coupled with direct practice in a vehicle to hear the audio system. As for this installer should be adjusted to the installation or placement until the point of the score sheet can be achieved with the maximum.
In EMMA SQ score sheet, the assessment is divided into 2 things that sound quality evaluation and assessment of the installation. Typically for such assessments presents a different jury. Now I will discuss the general picture SQ score sheet.
We discussed one by one on the part of the Sound Quality.
A. SOUND STAGE
Sound stage we describe it as a stage where we enjoyed some music, then we enjoy in the stage then we will feel.
A.1 Distance to Soundstage
What is the distance the listener is our ears with the singer on the first line.
A.2 Stage Width
Is the width of the stage, the distance between the left and the right,
A.3 Stage Height
Is the height of the stage, is a singer basically is a high level of our ears, so if we enjoy that are not too high or too low below us.
A.4 Stage Depth
The depth of the stage, we will be able to feel the layer / structure of a stage singer.
A.5 Ambience
For easy to understand, if the music was recorded in a large church, then the system should also give the impression of the room as we listened to in the church building as well.
score-sheet2
B. IMAGING
How can we imagine the position of the singer or other sources are based on the location of the boundary between the left and right, so we thought of as dashboards that big stage and has a boundary between the left and right. So simply stated, it can either be appointed by the hand placement and size, as well as authority, including size, shape and otority. Is that supposed to be in the center is right in the center or at other positions,
B.1 Left
Dipaling position was left of the stage (in this case the dashboard)
B.2 Left Center
Position located in front passenger side
B.3 Center
Right position limits anatara amid the most right and far left. (Not located amid dasbard)
B.4 Right Center
Position was directly in front of the driver.
B.5 Right
Position in the far right platform or dasboard
* is usually in the deliberations using EMMA CDs using five piano tracks
score-sheet3
C. Tonal Accuracy
The resulting sound should be as much as possible to the original approach, for example if the tape was then we have to live in such a way as to listen to a live recording
C.1 Sub Bass
Bass must be clean, fresh, powerful, not too fat, or thin .. too much bass will make the bass come from behind and makes us feel the bass was too fat in the lower frequencies.
C.2 Mid Bass
Midbass is good to be clean, free of humming, no part of vibration of the car. Excess midbass frequencies, making the sound stage downstairs and heard voices coming from the bottom (mid bass).
C.3 Mid Range
The place of human vocals, important, for the good.
C.4 High Frequency
Area tweeter. Tweeter jim-dandy would seem to flow, there is no sound harsh (rough), no decay, many symbilance.
D. OVERALL spectral Ballance
Harmony among them all, how accurate a good portion of the division in the subwoofer, midbass, midrange, and tweeter.
D.1 Normal Volume
By the time we listen with the volume of the normal position, what if we find harmony.
D.2 Higher Volume
By the time we listen with the volume higher position, what if we get harmony.
D.3 Listening Pleasure
How we can listen to the audio system from our sense fell a fun, enjoy, so that makes us feel as though we will want to jump down while listening.
Audio Tips: Placement on the Mazda2 Amplifier
Car Audio September 22nd, 2010
kabin small cars, currently increasing type again. Mazda2 is one of the cars would digadang staying off sales in 2010. We have a new car, which was launched yesterday, Wednesday (25/11) at the Four Season Hotel, Kuningan, Jakarta, a lot of positive response from SO’mers.
Many of the judge, if menyangi would Mazda2 Honda Jazz comes first in the market leading MPV small homeland. Though this market is very fat with a variant of crammed with a variety of different brands such as Toyota Yaris, Suzuki Swift and Hyundai i20. Mazda RX8′s brother is currently a lot of conversation pubik National automotive.
Start the Hooked SO’mers audio and are attracted Mazda2, not to worry about planting in the car audio system is. Talk audio in a tiny car would need its own tricks.
Can be viewed at the trunk space has a dimension less extensive, if the fear will disrupt the daily needs SO’mers transport. It was a little trick to make free audio sound in a tiny cabin.
In the Mazda2 or other variants, here takes place so that SO’mers efficiency can still use the trunk. Required amplifier (power) which has a channel at least 4 or even 6 in 1 channel amplifier. This is intended to be more efficient in the placement, and reduce the quantity of amplifiers.
For simple installation, it was a 2-channel amplifier and 4 channels is enough, but who wants to create a more complete system would not want to take power by more than 2 channels.

Small dimensions
To get around the tiny cabin, find the amplifier that has a small dimension with adequate quality. So how placementnya? amplifier can be placed under the front seat, so that the trunk remains roomy.
There are several advantages amplifier mounted under the seat:
1. Do not need a lot of eating places / spaces
2. Cable used is shorter so that it can use a cable with good quality or high-priced cable.
3. Short cord makes less and less resistance.

With this installation was not without threats, sebaiknnya amplifier that is still given protection by providing a silencer on the ground floor to avoid short happens when positive cable off the power. In addition to prevent overheating, the fan assembly is also required.
Now create the trunk SO’mers who want do not want to look empty. Placement amplifier can be placed sideways on the side of the cabin, using the cover panel. However, this option also considering the factor of beauty / trunk artistic sector.
Audio Tips: Storing detection with 5 Steps
Car Audio August 2nd, 2010
Storing, we often hear the word, but what is storing? why can arise storing? Some say, storing a scourge for some Installer, because to throw normally can take time, but it can also be very brief.
When storing hard to overcome, this would obviously take time, SO’mers will be annoyed. Not to mention annoying to overcome the Installer jobs in the workshop. Before going, to avoid detection.
Storing the resulting interference becomes smooth sound, sound distortion that makes comfort mendenger be delicious. So when he heard the car audio system, the ear will hear the noise that came out of the speakers.
More specifically, it is storing noise into the audio system, often the engine sound, sound from audio system out of voice “ngiing” like an airplane. When gassed the engine sound will grow fast. Sometimes there are other weird sounds.
storing2
Here are 5 steps detection storing:
1. Voltage drop, this is the difference voltage received by audio devices starting from the head unit to the amplifier. Practical solutions to prevent it is the source of all power to the device from the same place (1 point) starting from the head unit to power.
2. Ground Loop, this is the accepted mass differences of each device is not the same, to prevent it as the first point. As a result, the source of ground in the car
to 1 point as well.
3. Check Altenator, the car sometimes found altenator to charge batteries that are less good, this resulted in unstable electricity is not only electricity and sometimes leaked into several sections along the vehicle. As a result, would be installed any audio model and the solution must be storing the altenator is given capacitor or the most easily please replace altenator.

4. Interference, ie if the speaker cable near electrical cables on the vehicle, causing electrical interference into the speaker’s voice, as good as any electrical cables must be radiation around the cable. Anticipation is the interference occurs away RCA cables or speaker of electrical cables, each cable is neatly arranged according to their respective channels.
5. Storing equipment, this occurs by audio devices such as power, etc., the solution is replacing a simple audio device storing impaired.
Usually it is 5 often result in storing the vehicle. Hopefully this material, can be useful for SO’mers.
Select Head Start Unit Sound Quality (SQ)
Car Audio February 14th, 2010
Head UnitImage a car audio device first read the audio signal from a media / sources such as tapes, CDs, DVDs or the other, certainly the quality and features are important in producing its sound quality. Especially for fans of audio streams SQ, this article describes features required for the Head Unit for SQ orientation. Do not forget to read also list recommendations for legendary Head Unit orientation SQ.
Especially for SO mania who want a high-quality voice or audio concept Sound Quality (SQ) in the car, of course, must use the head unit designed to promote the sound quality, for there are some features to watch out for its existence before choosing the future head units that are capable of producing a sound quality with the concept of Sound Quality (SQ).
Recommended Time AlignmentMenurut Sandy, car audio installer from Sterindo Autosound audio workshop, several features that must exist in the head unit to promote the sound quality (SQ) is:
1. Recommended Time Alignment: Ensure that the head unit has this feature, because the time alignment function to help equalize the sound propagation distance between the left and right speakers, front and rear, so that the voice sounded more comfortable and appropriate to the listener’s ears.
2. Features Built-In Crossover: The existence of this feature is very important, especially for the audio system with active crossovers commonly referred to as bi-amp system, because its function to set the frequency / cutting the right frequency to get to the speakers. Without this feature the two possibilities can happen, the first speaker could burst / damaged, especially the most sensitive to the tweeter and the two voices to be heard is not controlled or messy.
3. Features Equalizer (EQ): Equalizer (EQ) important to suppress the frequency of excessive noise in the car so that the voice sounded more appropriate, select the EQ it can be custom set.
Third fundamentally very important feature exists above the head unit to a car audio system is the concept SQ. But even better would be if you choose a head unit also has been having the following specifications:
1. D / A Converter (DAC) 24 bits: Select a head unit that has 24-bit DAC specifications compared to the 16-bit DAC, this specification relating to the resolution level of the reading head unit through the conversion process the digital signal into analog audio from a media / source, such as CDs, DVDs, etc.. The higher the DAC means that the resulting sound quality will get better and natural. Special specifications for this one, it’s been a lot of manufacturers head unit underclass / entry level with these specifications, for it should not be used as a benchmark, better quality is directly proved just by listening to the voice, because the components that determine the resolution of 24 bits in head unit entry-level class will also affect its quality. Only the head of the class units / hi-end has 24-bit DAC resolution and quality of pure, because the components that support the inside using hi-grade components, so if it wanted to buy a head unit that hi-end class choose which already has a specification D / A 24-bit.
2. 3 RCA Output: Head unit that has 3 RCA outputs would be better to be paired on a car audio system. Because usually a head unit which has only 2 RCA output specification does not have time alignment features, usually features only the EQ and built-in crossovers that are not so precise / limited.
“In this case the most major is that we also have to jelly in choosing a car audio installer, because from the beginning to the end of an audio installation, installer very big role. The latter in selecting the unit head or even the speakers until power is better to adjust the existing budget, and to ask questions and seek information and quality products such as what to get to the installer, and then we hear and trust the test on their own tastes, do not influence the taste of Another, not necessarily appropriate. “said Sandy closed the interview SO.
