Philips PSC724 Ultimate Edge



The recent trend of PC integration into the user's living space finds the once small and dingy computer room becoming a thing of the past.  With manufactures now offering PC solutions which showcase features that rival many mainstream audio components, families are now finding their "digital living room" to be the new media back-bone of their lives.

This is where Philips new soundcard, the PSC724 Ultimate Edge, steps in.  Offering discreet 24-bit, 6-Channel High Definition Audio playback/recording, users can turn their PC into a high-end audio center with a simple upgrade.  In addition to promising high end specs, Philips has integrated their newly redesigned Sound Agent 2 GUI to bring together all the features of the card into one highly configurable, easy to use interface.

Features and specifications aside, we here at HotHardware were looking forward to examining Philips' latest and greatest PC Audio product.  A good majority of us here at HotHardware are audiophiles and this is our first look at a Philips product, so it should be an interesting showcase.

The Philips PSC724 ships with your standard retail package.  Included with the card itself, we found one driver CD, a quick installation guide, the warranty booklet and some literature about other Philips products.  Missing from the bundle is the standard CD Audio connector and a SPDIF Coax patch cable.  Though these are not necessary components that are required to connect the soundcard to your system, users who wish to take advantage of the digital interface may be disappointed to find that they need to purchase supplementary cabling.

Looking at the card from a general construct point of view, we where pleased with the overall build quality.  In reference to the pictures above, one can clearly see the five 1/8" mini-jack connectors in their standard color scheme; Line-In, Mic-In, Front Out, Rear Out and Center/LFE.  The only abnormality, when compared to others, on the soundcard is the replacement of the once popular gameport with the SPDIF Out connector.  In some cases, manufacturers will include the gameport on an additional extension bracket. However, in the case of the PSC724, Philips has done away with it all together under the assumption that most user are now using USB interfaced gaming peripherals.
