System Overview

For the ultimate in multimedia power and Internet connectivity, look no further than the Apricot XEN-PCM ONLINE. This high performance range has been designed from scratch to give you everything required to mix information with high quality sound and graphics. Just one look at the stylish casing reveals that this stereo-speakered power-house means business.

In the last 12 months there has been an explosion of interest in the Internet, Information Superhighways and almost anything to do with CyberSpace. The result has been growing demand from both home and business users for systems to access the world wide web. Whatever your objective - simply getting connected to an e-mail service or exploring subjects as diverse as the convertibility of the Russian rouble or the next antipodean eclipse - you will marvel at the capability to share information and ideas with people from around the globe, using the fast, integrated modem of the XEN-PCM ONLINE.

The Essential Mix

Straight from the box, the XEN-PCM ONLINE is all you need to use and enjoy the rich assortment of multimedia applications now available. The advanced Sound Blaster system provides lucid recording and playback of all sound and music from multiple sources such as MIDI keyboards or the integral CD-ROM. The high quality Sony quad speed drive is chosen for its superior performance, rapidly accessing everything from music CDs to image packed Kodak PhotoCDs. The resulting plethora of input signals and sounds can be controlled using the XEN-PCM ONLINE's pre-loaded mixing utilities and then output via the amplified stereo speakers.

Classic Performance

The XEN-PCM ONLINE range offers two powerful processor options, the Intel 486DX4-100 and the Intel Pentium-75 so that you can match the system to your exact needs. Accelerated local bus video is standard on all models, while Pentium-based systems utilise the Cirrus Logic GD5434 graphics accelerator. Also optionally available is the last word in video control: The Matrox MGA Impression Plus rated at over 40 million WinMarks using the new WinMarks benchmarking system - WinBench Vr4.

Features and Benefits

Sound Blaster audio technology

A key element of a multimedia system is the audio controller and the XEN-PCM ONLINE is centred around the industry leading Sound Blaster Vibra-16. Precision Digital Signal Processing circuitry that can record and play back sounds up to, and beyond, the range of human hearing ensures that your ears will deceive you.

Integral quad speed CD-ROM drive

For serious multimedia work a high specification CD-ROM drive is essential. For this reason the XEN-PCM ONLINE is supplied with an integrated device positioned behind the unique centre fold-down hatch. The drive spins CD-ROM disks at four times the normal speed in order to provide much improved access times. When you wish to play music CDs the drive automatically returns to single speed to provide excellent sound quality.

High Performance Data/Fax Modem

Get connected to other online users with e-mail and fax; explore the wonderful world of the Internet. Included with each XEN-PCM ONLINE is the necessary hardware and software plus a special Compuserve offer (1 month FREE trial*) to help get you started.

* 1 month membership and 10 usage

Amplified stereo speaker system

The XEN-PCM ONLINE is a completely integrated system and unlike most other multimedia machines, this includes the speaker system. Twin amplified speakers neatly set within the front panel of the XEN-PCM ONLINE provide superb stereo response. Alternatively, an output jack at the rear of the casing allows you to channel sound to headphones or an externally amplified stereo system.

MIDI Interface

Linking keyboards, sequencers and other instrumental hardware to the XEN-PCM ONLINE is quick and easy. A full-duplex MIDI port is provided as standard to allow the transfer of digitised music data.

486DX4-100 or Pentium-75

A choice of processor options allows the correct configuration to be matched exactly to your performance and budget requirements. As those requirements change, each system processor can then be upgraded to meet new demands. Industry-standard processor sockets make upgrading to next generation processors a quick and easy task.

Supplied with 8MB RAM

With 8MB on-board, every XEN-PCM ONLINE is ready from the outset to tackle Windows, OS/2 and other memory intensive applications. Upgrading is made easy and cost effective using industry standard SIMMs (Single, In-line, Memory Modules) which are widely available.

High capacity, high speed hard drives

Each XEN-PCM ONLINE model is provided with high performance hard disk storage specifically selected to handle the high volumes of data created and used by multimedia applications. Extensive testing by Apricot's System Verification Group ensures that only the highest quality drives from the world's leading vendors are chosen.

Video acceleration

The stunning video performance of the XEN-PCM ONLINE models is made possible by the use of accelerated local bus video processors. Using the 32-bit local bus to couple each video accelerator to the main system processor ensures that even the most graphically intensive applications move like lightening.

1MB video RAM minimum

A minimum of 1MB video RAM means that every XEN-PCM ONLINE is capable of providing non-interlaced, high resolutions straight from the box.

High resolution 14", 15" and 17" Monitors

Each XEN-PCM ONLINE is supplied with a choice of high resolution monitors that perfectly match the fast graphic capabilities of the systems. All monitor options meet and exceed the latest European standards for safety and emissions.


By adhering to the latest computer industry standards, Apricot engineers have ensured that the XEN-PCM ONLINE can be easily upgraded with widely available components and peripherals.

Built in the UK by Apricot

With BS 5750 (ISO 9000) accreditation from sales, marketing, research and development through to manufacture in Scotland, Apricot have been building quality into every computer system for more than twelve years.
