With a name like Ego you might expect the company to be one of many in the West but it’s not; it’s Korean, our friends in the South.

The Waveterminal 192L is one of three PCI Waveterminal cards designed for musicians wanting to move beyond 16-bit/44.1kHz recording. It supports 24-bit/192kHz digital audio playback (24-bit 96kHz recording) and features a stereo analogue In, a mono Mic In complete with +12V preamp, six Outs in the form of three stereo pairs, and a digital optical Out.

Installation is straightforward although Windows’ New Hardware Wizard struts its stuff for every port on the card which seems a little excessive. It also installs the MIDI drivers by default although you need the optional MI/ODI/O card in order to use MIDI. In use with Cubase, for example, the MIDI drivers took over the system and wouldn’t allow the existing MIDI port to be used! The solution was to disable the Waveterminal MIDI driver in the Device Manager and then reboot.

Console control

The Waveterminal 192L Console gives you quick access to and control over the card's major functions.

A software Console is installed during installation and appears as an icon in the system tray. From here you control most of the card’s functions. You can set the sample rate or let the card set the rate automatically according the audio file’s sample rate. There are switches for the digital connections although some of these require the MI/ODI/O add-on.

One of the analogue Ins is for a Mic but you cannot use this and the other analogue In at the same time. A switch on the Console makes the choice. When using a Mic you can select phantom powering and adjust the input level. This allows you to use both condenser and dynamic Mics.

Hard monitoring
One of the problems with many audio cards is that latency adds a delay to monitoring, particularly if you monitor through a software application such as a sequencer. The 192L supports hardware monitoring which routes the input directly to the output, bypassing any software latency problems.

On the right are faders for adjusting output levels and a useful feature here is the ability to control them with the mouse wheel.

You can also set the latency although it’s in samples rather than milliseconds. The actual latency you’ll achieve will vary according to the application and your computer system. However, the 192L supports hardware monitoring which should avoid many common monitoring problems. In monitor

Go direct

Waveterminal - DirectWire can transfer audio internally between different applications.One of the card’s most interesting and unique facilities is DirectWire. This is a feature of the E-WDM driver that allows you to transfer digital audio between different applications, even if they are using different drivers.

Supported drivers include MME (for WinAmp, WaveLab and Cakewalk), Multi-MME (for Sonar, PowerDVD and Win DVD), ASIO (for Cubase, Logic, Nuendo and Reason), GSIF (for GigaStudio). In many cases you could simply export audio from an app and import it into another program but where this is not possible, DirectWire offers a solution.

Hey – let’s call it a…

Egosys' MI/ODI/O - candidate for the worst name in the history of digital audio - has an optical input on the backplane while the MIDI and S/PDIF connections run into one connector cable.Apart from having what is probably the worst name of any product in the history of digital audio hardware, the MI/ODI/O is simple and easy-to-use. It’s an optional add-on for any of the Waveterminal 192 cards and it adds an optical digital input, a S/PDIF In and Out and a MIDI In and Out to the system.

It connects to the Waveterminal card with a ribbon cable. The optical input is on the card’s backplane while the S/PDIF I/O and MIDI I/O hang off the end of a short connection cable. There are no extra drivers to install – the 1902L having done all that – so installation is simply a matter of plugging it in.

If you need an optical In then one might be tempted to ask why not buy a card so-equipped in the first place. Like-wise with S/PDIF. MIDI is a different kettle of coconuts because many quality audio cards, unlike consumer cards, do not include a MIDI interface. If you only need one MIDI I/O, there is a certain amount of sense in having it linked to the audio card. However, it is only one I/O. It might be enough for many folk, particularly if they’re computer-based, but if you have a couple of sound modules or more than one MIDI input, one I/O may not be enough. Something to consider. But then at the price it’s a good value add-on.

Check the specs of the 192L and you might expect a dynamic range slightly better than 100dB and 104dB, but there’s more to audio quality than a few benchmarks and the card sounds excellent. As a cost-effective move up to 24-bit recording, the system is very attractive.

Good quality audio
Mic input with phantom power
Phantom power on/off
Software control panel
Low-cost expansion option to S/PDIF I/O and MIDI I/O

Can’t use Mic and analogue In at the same time
Limited number of audio Ins
Tos-Link digital out doesn’t support 192kHz
MIDI & S/PDIF I/O extra
MI/ODI/O has only one MIDI I/O

A well-priced, good quality audio card with an expansion option; ideal if your I/O requirements are not overly ambitious.
