Technical Specification

Minimum PC and Network Requirements

PC Hardware

  • Pentium 4 class processor running at 2.6GHz or higher
  • 256 MB RAM (stand alone) / 512 MB RAM (used with Virtuoso)
  • Sufficient hard drive space for the installation of Soloist. This can take up to approximately 75MB, depending on how many of the Dynamic Link Library and Active-X files included in the setup package are already installed on the PC.
  • Sufficient hard drive space for storage of temporary audio program and recording files.
  • SVGA Graphics capability with minimum of 800×600 screen resolution and 64K simultaneous colours (16-bit Colour Depth)
  • Mouse or other screen pointing device
  • A sound card with full duplex (simultaneous record and play) capability. The sound quality derived from using Soloist software is dependent on the quality of the sound card being used.  The sound card must have a “microphone” input and “headphone” output.  When used with Virtuoso™ Instructional Control Software, “Stereo Mix” capability on the record side of the sound card is required for some functions to perform as is usually desired.  High Definition (“HD”) sound cards are not currently supported.  For more information about Sound Cards and their use/functionality with Soloist, refer to:
  • High quality headset (with microphone)
  • USB 2.0 port for use with the SANS SHS-100 headset with USB Sound Card
  • 100-BaseT NIC (Network Interface Card) configured for TCP/IP communications

Operating System

  • Windows 2000 with Service Pack 4 or Windows XP with Service Pack 2
  • Windows Media Player Version 9 or higher
  • Microsoft DirectX Version 9.0c
  • Microsoft Visual Studio 2008 C++ redistributable SP1 (Windows XP only)
  • Windows Firewall must either be turned off or “Exceptions” made for Soloist.exe, SANSCast.exe, WinVNC.exe and LPEC Helper.exe (all contained in the folder that Soloist is installed into).

Notes about Other Software

Any other software installed on the PC that can consume considerable CPU time (more than a few percent) can negatively impact the performance of the Soloist software for which CSL cannot be responsible. Such software includes (but is not limited to) anti-virus software.  Other security software such as “Deep Freeze” must be completely disabled when installing and configuring the Soloist software and consideration given to how they may interact with the operation of the Soloist software when enabled.


  • Ethernet topology
  • 100 Mbps Full Duplex –1 Gbps recommended
  • All PCs in the system must be using TCP/IP protocol and “Client for Microsoft Networks”.
  • All PCs in the system (including file server(s)) must be within the same network segment.
  • For best results regarding minimal and uniform system latency, the use of dedicated network switches and proper cascade or stacking modules (where required) are recommended. The main objective is to isolate the system from extraneous network traffic and the rest of the network from network traffic generated by the system as much as possible and practical. Establishing a VLAN for the system is a recommended consideration.
  • Both TCP/IP (for “unicast” or one-to-one) and UDP (for “multicast” or one-to-many) protocols are utilized – the network must support these requirements. Many of the Unicast ports are configurable, as are the multicast IP Address, ports, and Time-To-Live values. Refer to SANS’ document “SANS_Unicast_Ports_and_Multicast_Addresses-Ports.pdf” for details about the address/ports and their use.
  • Network switches must include auto-negotiate link speed and full IGMP compliance. This UDP multicast-forwarding feature must be enabled for all ports specified in the above-mentioned document, typically via management software incorporated into the switch.

‘We recently installed a 25 PC Language Lab using Sony Virtuoso after testing and demonstrations from ConnectED and a competitor company. We found that the Sony system seemed to be a better product with ease of use and ability for using the current resource library. We are very happy with the product and have found the training and support to be of great standard and very personable. The lab has been running for 4 weeks and the students and teachers are finding it a great aid. Glitches – I wouldn’t say there were many; as with every new system it requires customisation and the company were very willing to assist in configuration of these. I would recommend the company as the support and product has met the expectation of the Language Department’.
