About the DiO 2448

The DiO 2448 inputs and outputs support digital audio streams as wide as 24 bits, the highest resolution available at this time of printing. At sample rates of up to 48kHz, the DiO 2448 S/PDIF inputs may record a digital signal from your DAT, MiniDisc, CD player, or external A/D converter. The DiO 2448 S/PDIF and Analog outputs may be used to monitor the incoming S/PDIF signal or to output digital audio from your software applications. Below is a simplified block diagram of the DiO 2448. Please reference this diagram while reading the remainder of this section.

Basically, the DiO 2448 appears to your software as a stereo-input, stereooutput (2x2) audio card. There are three inputs to the card that may be recorded: Optical S/PDIF, Coaxial S/PDIF and internal CD-ROM S/PDIF. As you can see from the DiO 2448 block diagram the Optical and Coaxial S/PDIF streams are merged into one audio stream. This is not a true digital mixer, but instead a non-intelligent merger that combines the raw data streams. Therefore, only one of these jacks should be connected to an active signal at a time. Note also the CD-ROM S/PDIF header is wired directly to the Coaxial S/PDIF jack. In most cases, utilizing the internal CD-ROM S/PDIF header will prevent you from using the Optical and Coaxial S/PDIF inputs. Therefore, this header is primarily for using your DiO 2448 and computer as a “dedicated CD-ROM recording station” and not for recording from external S/PDIF devices.

The DiO 2448 also supplies two CD-ROM analog audio headers internally, with both popular formats supported. These provide a connection to the analog output of your computer’s internal CD-ROM drive (if you have one installed). Only one of these headers may be connected at a time. CD-ROM analog audio may be monitored at the DiO 2448’s Analog output only and may not be recorded. In order to retrieve data from an audio CD-ROM, we recommend the use of a “CD Ripper” software program. These are widely available programs (sometimes even available as shareware on the Internet) that allow reading audio tracks directly from your CD-ROM and storing the retrieved data to WAV format audio files. The resulting WAV format files may be imported into most audio programs.

The DiO 2448 provides three sets of outputs: Optical S/PDIF, Coaxial S/PDIF and Analog Audio. Any combination of these outputs may be connected at any given time. The two S/PDIF outputs are wired in parallel and therefore carry the same audio stream. The S/PDIF outputs may carry data from a software application, or they may be used to monitor the audio received at the S/PDIF inputs. On the other hand, the Analog Audio outputs may carry a different audio stream than the S/PDIF outputs. The Analog Audio outputs are connected to the output of an integrated digital mixer controlled by the Windows Sound System, and are therefore more flexible than the digital outputs.

The DiO 2448 Adapter Card

1. Coaxial S/PDIF Input: This RCA connector receives a S/PDIF stereo signal from an external coaxial S/PDIF device.

2. Coaxial S/PDIF Output: This RCA connector transmits a S/PDIF stereo signal to an external coaxial S/PDIF device.

3. Optical S/PDIF Input: This TOSlink connector receives an optical S/PDIF stereo signal from an external optical S/PDIF device.

4. Optical S/PDIF Output: This TOSlink connector transmits an optical S/PDIF stereo signal to an external optical S/PDIF device.

5. Analog Audio Outputs (Left & Right): These RCA connectors carry the left and right line-level signals to an external monitoring or mix-down device. The signal levels of these outputs are compatible with most consumer gear.

6. Internal CD-ROM headers, Analog: These headers (connectors) accept analog line-level audio from a CD-ROM player or similar source internal to the computer. Only one of these headers may be in use at one time.

7. Internal CD-ROM header, Digital: This header (connector) accepts a digital audio S/PDIF signal from a CD-ROM player or similar source internal to the computer. This header is wired in parallel to the coaxial S/PDIF input. Therefore only one of these connectors may be used at a time.

Quick Guide to Getting Started

Here is a list of the steps required to get your DiO 2448 up and running:

1. Physically install the card in your computer (see ‘Hardware Installation’).

2. Start Windows and allow Windows’ Plug-and-Play to prompt you for the DiO 2448 drivers via the Add New Hardware wizard.

3. Install drivers and support software (see ‘Driver & Software Installation’).

4. Configure your digital recording software to select the DiO 2448 ports as its active audio input and output devices (see ‘Using DiO 2448 with Software Applications’ and also your applications software manual).

5. Hook your digital audio gear up to the DiO 2448 (see ‘Typical DiO 2448 Setup’).

Hardware Installation

To mechanically install the DiO 2448, follow these steps:

1. Turn off your computer.

2. Remove the computer’s cover and position the computer so that you may easily access its PCI slots.

3. Select the PCI slot where you will install your DiO 2448 card. Make sure it is a PCI slot. If you don’t know what “PCI slot” means, check the owner’s manual for your computer. PCI slots are distinguishable from ISA slots by being shorter and set back farther from the outside of the computer, however some newer computers have only PCI slots.

4. Before removing the DiO 2448 from its protective anti-static bag, touch the metal power supply case of the computer in order to dissipate any static electricity your body may have accumulated. You might want to pick up a grounding wrist strap (available from electronics stores like Radio Shack) if you want to be doubly sure you aren’t carrying a static charge that could damage the card.

5. Remove the metal bracket that covers the access hole on the back of the computer. This bracket is usually fastened to the computer with a single screw. Save the screw for a later step.

6. Position the DiO 2448 card over the target PCI slot, fitting the card loosely over it with the DiO card upright. Press the card gently but firmly downward into the slot until the card is completely and squarely seated in the slot. If the card seems difficult to seat, a slight rocking motion may help.

7. Secure the DiO 2448 metal bracket down into the screw hole on the back of your computer using the screw you removed in step 5 above.

8. Connect the audio output of your internal CD-ROM player to the DiO 2448 if you wish to monitor it through the DiO 2448. A standard cable may have been supplied with the CD-ROM, either analog or digital, or one can be purchased at an electronics store. Please note that only one CD header may be used at a time.

9. Place the cover back on your computer.

Windows 98/95 Driver Software Installation

Included with the DiO 2448 is one or more Windows driver diskette(s) containing the software drivers for your particular operating system. To install the drivers, please follow these steps:
