Jeng Jie Car Audio Turns Family Cars Into Concert Halls

- 2007/09/20 -
As cars increasingly take on roles exceeding that of mere personal transport-often being demanded to be all-round platforms for recreation, entertainment and even status symbols-high-fidelity sound piped through car stereos is becoming essential and not an option. For that matter, it has been said that music can alter people`s moods in an instant. So it is understandable that a vast array of devices are designed to enhance the audio quality heard in the cabins of everything from Smarts to Escalades; while Jeng Jie Car Audio Co., Ltd. is right in the midst of developing high-quality car audio solutions based on its extensive knowledge of interior automotive environments.

Established in 1974, Jeng Jie`s own Focus Audio-branded line of car audio items has virtually muffled most other rivals in Taiwan by taking over more than half of the high-end car-stereo aftermarket on the island, as well as being a renowned leader in major export markets such as the U.S., mainland China, Hong Kong, etc.

Backed by the know-how and technologies it has built up over the years as a maker of upscale car audio equipment, Jeng Jie is committed to offering multi-media car entertainment products that bring drivers and passengers the ultimate in audio and visual experiences on-the-go, with an extensive line that integrates listening, seeing and communicating functions, such as amplifiers, speakers, sub-woofers, line-output connectors, base reactors, electronic cross-over, and many more.

With considerable R&D capability and manufacturing skills, Jeng Jie is able to consistently launch newer and better products that set trends to fully satisfy car audio buffs pursuing the next, higher level in car audio quality.



One good example is the SX6 six-channel, line-output connector, a signal-integration platform featuring precision, sophisticated design that effectively upgrades existing car-stereo sound without needing to modify original equipment in the form of OEM main unit or factory-installed amplifier.

According to Brian Huang, Jeng Jie`s marketing manager, the unique SX6 takes 2.4 or six-channel speaker signals from factory-installed amplifiers or main units and converts them into high-quality, low-noise pre-amp signals. In effect, the SX-6 offers the best of two worlds-allowing the addition of upscale, aftermarket amps and processors for enhanced sound quality while keeping the OEM main unit. In addition, the line-output connector features level-matching control functions for output adjustability according to personal preferences; while the SX-6`s circuitry allows for integration of selected channels into main ones. So, the SX6 is ideally efficient for improving car audio quality with factory-installed systems featuring active, cross-over speakers.

Many luxury-car owners who shun changing the OEM head-unit appearance or OEM interior integrity but seek improved sound, according to Huang, the high-end SX6 is clearly the best choice. Marketed via aggressive product strategies, the SX6 has won hot responses from owners of hallmark marques as Lexus IS 250, Audi QX7, Mercedes S-series, as well as upscale Japanese cars.

Another new product is the specialized digital bass reactor with built-in, balanced line adjustment, subsonic filter adjustment, ground isolation, bass-level output control, etc. This series is sought after in the U.S. market and the popularity is spreading to other continents.

Bass Reactor Lives MP3 Music and Radio Broadcasts

Huang points out that Jeng Jie developed the bass reactor to improve sound quality by enhancing the bass spectrum of audio broadcasts, with the bass-amplifier clearly improving sound quality, especially of MP3-format music and FM/AM radio broadcasts, which typically compromise the higher and lower frequencies.



Jeng Jie also develops various kinds of speaker boxes dedicated to different car models-the specifically-designed speaker boxes enable add-on speakers and amplifiers to be masked and hidden without interrupting original interiors. The company offers an extensive line of speaker boxes for many popular cars, including Toyota Wish and Yaris, Mazda-5, Mitsubishi Savrin, Suzuki Swift and Solio, etc., making the supplier a leader in the segment.

The Focus Audio car-audio amplifier is another product highlight for Jeng Jie, which is currently one of the most reputable developer, supplier in this field in Taiwan. In addition to various amps rated at different power outputs, Jeng Jie has also developed a series of audiophile-grade amps featuring vacuum-tubes for those craving warmer, softer tones that apparently are beyond the realm of counterparts using ICs and digital parts.

Huang claims that his amps feature vacuum tubes imported from Philips stateside and are paired to assure the highest accuracy, a key factor for precise audio quality. Designed to be user-friendly and personalized, this series of vacuum-tube amps allow users to easily change tubes for targeted effects.

Yet another new product that further resonates Jeng Jie`s commendable technical expertise is the four-coil woofer. According to Huang, Jeng Jie is currently one of a handful of companies capable of designing, making such specialized speaker. The number of coils in a woofer is directly proportional to its level of technical sophistication, Huang says. With a car amp and power supply pumping earth-shaking RMS watts, the four-coil woofer is the ultimate way to do justice to the sounds of Santana or Barry White, whether one is parked or cruising at triple speed-limit on the freeway, he says.
