• Comment: Many of the sources are from the company itself, and there is still a big issue where it sounds like an essay. Other sources listed are also primary sources, and a lot of them are used throughout the article repeatedly. UserMemer (chat) Tribs 15:04, 13 October 2024 (UTC)

• Comment: "Citations aren't mostly citations"? There shouldn't be a "what is it?" "how does it work?" section, this is not a how-to guide, this is an encyclopedia article. Utopes _{(talk / cont)} 19:29, 25 August 2024 (UTC)

Logic 7 will mostly be referred to as "Logic 7" in this article for simplicity, even though it was rebranded a couple of times, being called LOGIC7, LOGIC7 UpMix, LOGIC7 HD, Logic 7, etc....

Logic 7 is a surround sound processing algorithm made by an American company focusing on audio equipment known as Lexicon in 1996 with the introduction of the Lexicon DC-1 Digital Controller.

7.1 channel surround sound speaker positioning around the white dot, being the listener.

Functionality

In it's functional form, it is similar to Dolby Pro Logic II family , mainly Dolby Pro Logic IIx released in 2003. It was also of a 7.1 channel kind. Dolby Pro Logic II was originally created by Jim Fosgate, then reworked into a digital form with Dolby Laboratories, which came out later in 2000. It is a matrix based upmixer, just like Dolby Pro Logic family and the original Dolby Surround. Logic 7 at the time of release in 1996 was only competing with Dolby Pro Logic, which came out in 1987. Logic 7 differed, as it allowed for 7.1 channel surround sound, compared with Dolby Pro Logic's 5.1 channel surround sound limit. Logic 7 was more suitable for music, as it did not utilize the center channel as much, that was mainly used for dialogue, or the singer's voice. Logic 7 had a wide range of customization found on the Lexicon unit. There was also a wide frequency response range in the surround channels (453hz-20khz), compared to Dolby Pro Logic's (100hz-7khz) range. Dolby Pro Logic allowed for a single rear surround channel, in a stereo surround speaker configuration, they would both play the same mono sound. With the arrival of Dolby Pro Logic II, allowing full frequency response range and stereo surround speakers, this was no longer the case.

Hyundai

Hyundai Genesis 2009

Genesis

Eventually Hyundai partnered with Lexicon to put Lexicon's audio systems into their cars in 2009. First it was the model Genesis in 2009, which in the configuration with the 7.1 Discrete sound system featured 17 speakers in a 7.1 surround sound architecture, with one being a subwoofer, powered by an 11-channel DSP amplifier with 528W, speed sensing volume was present too. In this configuration, it featured a 6-DVD/CD changer, thus the car supported the playback of DVD-Audio/Video. It also had support for DTS-CD, so you could play discrete 5.1 audio such as Dolby Digital 5.1 and DTS 5.1, and then have it upmixed to all 7.1 channels available via Logic 7. It could also play PCM, MLP, MP3, WMA, DMB, XM Satellite Radio and HD Radio.

The cheaper option had 14 speakers with the one's missing being the two front door mid-range drivers and the center tweeter driver. It also did not have DVD or DTS-CD capabilities, thus only including a 6-disc CD changer, disallowing discrete 5.1 audio playback. It had the same amplifier too.

The later iteration of the Genesis, released in 2017, also called the G80 and G90 models were the first to not feature Logic 7 surround sound technology, and instead moved onto another Lexicon's surround sound processing algorithm which replaced Logic 7, called QuantumLogic.

It featured a 6-DVD/CD changer, Harman Infotainment, had support for iPod and USB conectivity. It could also play MLP, MP3, WMA, DMB, XM Satellite Radio and HD Radio.

Kia

Kia K9 2012

K9/K900/Quoris

Known as K900 only in the USA and as Quoris in other export markets. It is essentially a derivative of the Hyundai Equus and Genesis as previously mentioned. It was first released in 2012, and featured the 17-speaker Lexicon audio system as standard. It had a 900W power amplifier, a subwoofer, 12-channel digital sound processor including Discrete Logic 7 surround sound audio, which could upmix discrete 5.1 audio such as Dolby Digital 5.1 and DTS 5.1 to 7.1 channels, just like on the Hyundai Equus and the Genesis with the Discrete Logic 7 sound system. As mentioned above in the Hyundai section.

In the following 2016 and 2017 revisions, the Lexicon system was no longer available on the Premium V6 package, however it was standard on all other.

In the 2018 and onward versions, nothing has changed except speaker positions.

From 2021 and onward they stopped advertising the Lexicon system, due to the model being discontinued in Canada in 2018 and later in 2021 in the USA. The 2024 K9 isn't sold anywhere outside of South Korea.

In the 2024 revision all models except the Platinum package (base model) come with the Lexicon 17-speaker sound system, all else now newly use a Krell 14-speaker sound system.
