The Features

The most prominent feature on the Chaintech 9CJS Zenith would be the audio support which uses the VIA Envy24PT audio controller. It's possibly one of the best on-board audio you can find today and Chaintech is the one that offers an on-board solution. The VIA Envy24PT is one of the more powerful audio controller in VIA's line of Envy24 audio chips. Putting it together with the Intel 875P chipset is possibly one of the best ways to induce envy on current Sound Blaster Audigy2 users.

The VIA Envy24PT is a high performance 24-bit audio controller with support for sampling rates of up to 96kHz. This particular model can support up to 8 channels of audio and it will enable the user to playback some of the latest DVDs with 5.1, 6.1 or even 7.1 channels of audio. The DVD playback support is also extended to some of the newer Dolby Digital EX and DTS ES soundtracks. We think the support is excellent and would certainly offer power users a very cost effective alternative.

Bundled together with the motherboard, you'll find a sound card that plugs into the proprietary CMC (Chaintech Multimedia Card) slot which adds more than just the usual set of connectivities. On the card, you'll find three additional 3.5mm stereo jacks extending audio outputs to center/subwoofer, rear speakers and alternate left/right speakers. Adding all of these together with the existing outputs at the rear panel, the VIA Envy24PT can support up to eight channels of audio - making this a very ideal high-end audio solution for enthusiasts. In addition to these outputs, you'll also find an optical S/PDIF output jack and two 1394 ports on the card. On the card, you'll find an additional three input connectors, two analog inputs for the CD-ROM/DVD-ROM drives and another analog input for an auxiliary device. This is one of the rare times that we see a motherboard manufacturer actually making full use of the CNR slot and we welcome this with opened arms.

Here's another look at the bundled audio daughter card.

The other premium feature on the Chaintech Zenith 9CJS would be its double LAN support. Going in-line with NVIDIA's DualLAN vision, Chaintech decided to offer two LAN ports with the 9CJS Zenith. This is a very attractive feature indeed, as users who have more than just the usual network can make full use of two ports for various networking purposes. One of which could be used to connect the system directly to the Internet while the other port could be used to share the Internet connection. Software routing is nothing new and users have been doing that for a long time using two network cards. But with the two LAN ports offered here, software routing could never be easier, especially when Windws XP now comes with a very user friendly Internet sharing option.
