Quick Guide to Getting Started

Here is a list of the steps required to get your Delta 66 up and running:

1.Physically install the card in your computer and connect it to the Delta 66 breakout box (see ‘Hardware Installation’).

2.Start Windows and allow Windows’ Plug-and-Play to prompt you for the Delta 66 drivers via the Add New Hardware wizard. Install drivers and support software (see ‘Windows Software Installation’).

3.On the Mac, drag the Delta extension to the Extensions folder, and the appropriate ASIO driver to your application’s ASIO folder. Restart. If not using ASIO, set the Sound Manager to Delta (see Mac Installation).

4.Configure your digital recording software to use the Delta 66 as its active audio device (see ‘Using the Delta 66 with your Software Application’ and also your software application’s manual).

5.Hook up your digital and analog audio gear (see ‘Delta 66 Recording Tutorials’). Configure your Delta Control Panel software for proper monitoring and playback.

Hardware Installation

To mechanically install the Delta 66, do the following:

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 Delta 66 PCI host card. Make sure the slot 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 Delta 66 PCI host card 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

5

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.

6.Position the Delta 66 PCI host card over the target PCI slot and fit the card loosely over it with the card in the upright position. 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.Screw the Delta 66 PCI host card’s metal bracket down into the screw hole on the back of your computer using the screw you removed in step 5 above.

8.Place the cover back on your computer.

Now it is time to connect the Delta 66 break-out box to the PCI host card that you have just installed. Never attach the break-out box with the computer turned on. Doing so could damage the PCI card, and void your warranty. With your computer turned off:

1.Place the Delta 66 break-out box on a desktop in a convenient but secure place, or mount the unit in a 19” rack-mount chassis. Rack mounting may be accomplished with a universal rack-mount tray, using a 5mm screw through the tray and into the mounting hole on the bottom of the Delta 66 break-out box.

2.Connect one end of the supplied host cable to the 15-pin D-sub connector on the break-out box.

3.Connect the other end of the host cable to the 15-pin D-sub connector on the Delta 66 PCI Host card that now resides in your computer.

Delta Driver & Software Installation

The Delta 66 system includes a “Drivers CD” for Windows 98/95/NT and Macintosh, containing all Windows drivers, Macintosh drivers (including all ASIO drivers), and Delta Control Panel software. To install these on your system, please follow these steps:

Windows 98 Installation

1.After installing the Delta 66 hardware, boot your system and start Windows. During the Windows boot procedure, the new hardware will be automatically detected by the ‘Add New Hardware Wizard’, as shown here. Click ‘Next>’.

2.The ‘Add New Hardware Wizard’ will now ask how to locate the driver. “Search for the best driver for your device” is already selected. Click ‘Next>’.

3.Windows will give you a selection of locations to search. Make sure that only “Choose a Path” is checked, or click on the check box to do so. Insert the Drivers CD into your CD ROM drive. Type in the drive letter of your CD drive (we will assume here that it is D:\) and the path to the Delta drivers, which will be D:\Delta Products\Delta98. Click ‘Next>’.

4.The ‘Wizard’ reports that its Windows driver file search has found the M Audio Delta 66. Click ‘Next>’.

5.Windows is now ready to install the driver files from the specified location. Click ‘Next>’. Windows will start to copy the files and show you a progress report screen.

6.The Wizard reports that Windows has finished installing the software. Click ‘Finish’. Your Delta 66 is ready for action.

After completion of the driver installation, Windows may require you to restart Windows. If it does request a restart, remove the Drivers CD from the CD drive and respond by clicking “Yes”. The system will restart and your Delta 66 is ready for play.

Windows 95 Installation

1.After installation of the Delta 66 hardware, boot your system and start Windows. During the Windows boot procedure, new hardware will be automatically detected.

2.Choose the Install of “driver from disk provided by hardware manufacturer,” then click OK.

3.An ‘Install From Disk’ dialog will prompt you to copy files from the A:\ drive. Insert the Driver software CD into your CD ROM drive. Type in the drive letter of your CD drive (we will assume here that it is D:\) and the path to the Delta drivers, which will be D:\Delta Products\Delta98 (these drivers also work in

7

Win95). Click ‘Next>’.

4.Windows will start to copy files, with a progress indicator on the screen. Once this process completes itself, your Delta 66 will be ready for action.

After completion of the driver installation, Windows may require you to restart Windows. If it does request a restart, remove the Drivers CD from the CD drive and respond by clicking “Yes”. The system will restart and your Delta 66 is ready for play.

Windows NT Installation

1.Power up your computer after physically installing the Delta 66 card.

2.Go to Start | Settings | Control Panel and double click on ‘Multimedia.’ Click the ‘Devices’ tab, then click the ‘Add’ button.

3.“Unlisted or Updated Driver” will be highlighted at the top of the list. Click OK.

4.The ‘Install Driver’ box will prompt you to insert the driver disk, and the A: prompt will appear as the path. Insert the Drivers CD into your CD ROM drive. Type in the drive letter of your CD drive (we will assume here that it is D:\) and the path to the Delta drivers, which will be D:\Delta Products\DeltaNT. Click OK.

5.The “M Audio Delta Interface Card” driver will appear in the Add Unlisted or Updated Driver dialog box. Click OK.

6.Windows NT will require you to restart your computer for the changes to take effect. Choose “Restart Now.” Upon restart, your Delta 66 will be ready for use.

Macintosh Installation

1.Open the System folder on your Macintosh hard drive. In the System folder, locate the Extensions folder.

2.On you Drivers CD disk, open the Delta Products folder, then the Delta 66 folder. Place the extension file "Delta 66 Driver" in your Extensions folder by clicking on it and dragging it to the Extensions folder.

3.If you are using a music program that uses ASIO drivers, it will also have an ASIO folder within the application’s folder. In your Mac Delta Drivers folder you will find three Delta 66 ASIO drivers. For Cubase versions 4.x, use the "ASIO2 Delta66" driver. For Metro, or earlier versions of Cubase, use the "ASIO Delta66v3" driver. For any music program that is not ASIO2 capable, use the “ASIO Delta 66” driver instead (check your program’s documentation). Place the file "ASIO Delta" in your program's ASIO folder by clicking on it and dragging it to the ASIO folder.

4.Drag the "DeltaPanel PPC" file onto your Macintosh hard drive. You can run the Delta Control Panel from any place that's convenient, though music software applications that use ASIO will allow you to launch the Delta panel from within the program. If not, we suggest creating a alias to the control panel by

8

highlighting it and pressing Command (Apple key)+M. Then, drag the alias to the desktop.

5.With the Delta 66 PCI card installed, restarting the computer will load the Delta 66 extension. You will be able to visually see the Delta extension icon pass by as your system loads extension.

6.Go to the Apple menu |Control Panel | Sound. You should see the “built-in” sound icon, plus the Delta icon if your Delta 66 is properly installed. If your music program does use ASIO, leave the Sound Manager driver set to "built-in" for both Sound In and Sound Out. If your program does not use ASIO (check your software’s documentation) and you will be using the Sound Manager to communicate with your Delta 66, set Sound In and Sound Out to “Delta.” See the section “Hardware Settings Page” in the Delta 66 “Control Panel Software” section for information on selecting Sound Manger inputs and outputs. Your Delta 66 is now ready for use.

Verifying Windows Driver Installation

Windows displays the Delta 66 driver status in the Device Manager page of the System Properties dialog box. The Device Manager page is opened via the Windows Start button: select Start | Settings | Control Panel | System | Device Manager. With the Device Manager displayed, click on the ‘+’ next to “Sound, video and game controllers” to open a list of devices, the Delta 66 being a device of that nature. Below is an example view of the Device Manager.

9

This example shows the M Audio Delta 66 and Midiman WINMAN 4x4/S (another product shown here only as an example) entries in the Windows Device Manager device list. The Delta 66 is properly installed with no conflicts, as is the WINMAN 4x4/S. If you do not see your M Audio Delta 66 in your Device Manager in this fashion, please jump ahead to the “Troubleshooting” section of this manual.

Verifying Delta Control Panel Installation, PC & Mac

In Windows, open the Windows Control Panel (do so via Start | Settings | Control Panel ). If your Delta 66 hardware and Delta Control Panel software are properly installed, the Windows Control Panel should display an “M Audio Delta H/W” icon. By double-clicking on that icon, you may launch the Delta Control Panel software. Also for convenience, you may create a shortcut on your desktop by dragging a copy of the “M Audio Delta H/W” icon from the Control Panel to your Windows desktop using your mouse or trackball. After completing the drag operation, a dialog box will ask you if you wish to create a shortcut — click on ‘Yes’. Once the shortcut is installed, all you have to do is double-click on the shortcut icon on your desktop to launch the Delta Control Panel software.

On the Macintosh, the Delta Control Panel may be placed anywhere on your hard drive, or any partition of your hard drive that you find convenient. Once the control panel file has been dragged from the CD onto your hard drive, you may double click it to launch the Delta Control Panel software. You may create a alias to the control panel by highlighting it, then holding Apple key+M. This alias can then be placed on your desktop.

NOTE: When using a music software program that is ASIO capable, launch the Delta Control Panel software from within that program. Some of the control panel functions will be controlled from within that program, such as master clock setting and sample rate, so it is desireable to launch the music program first, and then the Delta Control Panel from the the program’s “launch” or “control panel” button. Without the music program open however, it is okay to open the Delta panel from your desktop or other location.

Delta System Overview

Delta’s Analog Input/Outputs

The Delta 66 Digital Recording Interface’s analog inputs and outputs are compatible with a wide variety of audio products. The Delta Control Panel software allows you to configure the signal level of each analog input individually, and all analog outputs as a group. Signal level settings of +4/Consumer/-10 are available. Selecting the ‘+4’ radio button configures the channel(s) for use with +4dBu signal levels, compatible with most musical instruments and professional mixers. Selecting the

10

‘–10’ setting sets up the channel(s) for -10dBV nominal signal levels, commonly used with consumer equipment such as CD, MiniDisc, cassette tape and DAT players. The ‘Consumer’ setting is preferred for semi-pro audio equipment and some consumer equipment that is too ‘hot’ for the ‘-10’ setting. The ‘Consumer’ setting offers approximately 6dB more headroom than does the ‘-10’ setting. Semipro and consumer devices’ signal levels vary from manufacturer-to-manufacturer and even product-to-product, so a little experimentation between Consumer and –10 settings may be required for optimal results.

NOTE: In order to preserve its high dynamic range and minimize distortion, the Delta 66 does not have microphone pre-amplifiers built into it. Therefore direct connection to a microphone is not recommended. Instead run the microphone signal through a microphone pre-amp (such as the Midiman "Audio Buddy™") and then connect the pre-amp output to the input of the Delta 66.

All analog jacks on the Delta 66 break-out box are of the 1/4” TRS (Tip-Ring- Sleeve) variety. The TRS jacks allow connection to either balanced (typically professional) or unbalanced (typically consumer or semi-pro) equipment. +4dBu balanced configurations provide the highest performance and should be used whenever possible. However, the Delta 66’s analog connections support combinations of balanced and unbalanced, +4dBu, consumer, and –10dBV level signals.

The Digital Monitor Mixer

The Delta 66 Digital Recording System has a hardware digital audio mixer built into its PCI controller chip. It accepts digital audio streams from all hardware inputs and all outgoing software audio devices, mixes them with 36-bit internal precision and then provides the mixed output to one or more locations. For the purpose of monitoring, the output of the mixer may be routed to the first set of Delta 66 analog outputs (H/W OUT1/OUT2 as a stereo pair) and/or the S/PDIF digital output. At the same time the mixer may be used for stereo mix-down, with the mixer’s output recorded into the user’s application software. The digital audio mixer is configured and controlled by the included Delta Control Panel Software.

The Patchbay / Router

In addition to the built-in monitor mixer, the Delta 66 Digital Recording Interface includes an output patchbay/router. The patchbay/router allows each output (analog or digital) to be connected to a variety of input sources. The Delta 66’s outputs may accept audio from software sources (the output devices visible in your audio software applications) or from hardware sources such as the analog and digital inputs or the monitor mixer. This capability makes the Delta 66 quite flexible for WAV output, monitoring, or directly connecting inputs to outputs for “system test” purposes.

11

Synchronization

For proper operation, the entire Delta 66 system is always synchronized to a single master clock. The master clock is chosen via the Delta Control Panel software and this clock may be derived from either the Delta 66’s internal crystal oscillators or S/PDIF In. Most of the time the master clock is taken from the internal crystal oscillators. However, the S/PDIF option is used in situations where the Delta 66 must be synchronized to external digital audio or sample rates.

As stated, most of the time the master clock is derived from the internal crystal oscillators. Operation in this mode is similar to that of a generic sound card — for instance, when a WAV file is played through the Delta drivers, the software application playing the WAV file is responsible for setting the sample rate in the sound card hardware. The Delta 66 supports these sample rates by using either of its internal crystal oscillators and dividing the rate of that oscillator by some value to derive the proper sample rate.

In situations where S/PDIF In is being used, the Delta 66 should be configured to get its master clock from the S/PDIF In data stream. The reason for this is simple — even if the sample rates are set the same, an S/PDIF data stream coming from an external source is rarely going to be in sync with the Delta 66 (or other digital audio devices in the system for that matter). If the master clock were set to use the internal crystal, then the incoming S/PDIF audio would have “pops,” “crackles,” and other undesirable audio artifacts present in it. Instead, setting the master clock to “S/PDIF In” will synchronize the Delta 66 to the S/PDIF input data and its digital audio will be transferred properly.

Finally, the S/PDIF In option may be used to operate the Delta 66 at non-standard sample rates. When this option is selected, the Delta 66’s sample rate will automatically match that of the incoming S/PDIF data stream.

NOTE: When the S/PDIF In is selected as the master clock source, the Delta 66 mixer’s frequency response will be affected by whatever sample rates you inject at the S/PDIF In. This is because (1) the digital mixer operates at the same sample rate as the rest of the board, and (2) sample rate and frequency response are directly correlated.

Using the Delta 66 with your Software Application

Once the Delta 66’s hardware and driver software are properly installed, it is ready for use with your music application software. Some of these applications may require you to highlight or enable the Delta 66 drivers within the program, and others may have a utility that analyzes or profiles the audio cards in your system and enables the drivers. Your software should have an audio device driver setup page.

WINDOWS MME AUDIO INPUT DEVICES: All Delta 66 analog and S/PDIF inputs may be used simultaneously for a total of 6 input channels. Within your software application(s), the names of the Delta 66 audio input devices are:

12

PCM In 1/2 Delta-66

PCM In 3/4 Delta-66

S/PDIF In Delta-66

Mon.Mixer Delta-66

The PCM In devices allow recording a stereo stream directly from the specified analog input pairs. The S/PDIF In device allows you to record a stereo stream directly from the S/PDIF input. The Mon.Mixer device allows stereo recording from the digital “monitor” mixer built-into the Delta 66. The audio data recorded from this device is the mix of input and output streams set up in the Delta Control Panel software (see Delta 66 Control Panel Software section).

Note that all of the input devices are stereo. Your application software may break these down further to “left” and “right” mono devices. Therefore you may see them as “Left PCM In 1/2 Delta-66, Right PCM In 1/2 Delta-66”, “Left S/PDIF In Delta-66, Right S/PDIF In Delta-66”, or “Left Mon. Mixer Delta-66, Right Mon. Mixer Delta-66,” etc. from within your recording software.

WINDOWS MME AUDIO OUTPUT DEVICES: All Delta 66 analog and S/PDIF outputs may be used simultaneously for a total of 6 output channels. Within your software application(s), the names of the Delta 66 audio output devices are:

WavOut 1/2 Delta-66

WavOut 3/4 Delta-66

WavOut S/PDIF Delta-66

WavOut devices allow playing a stereo audio stream to the analog hardware outputs (for WavOut 1/2, 3/4), the S/PDIF hardware output (for WavOut S/PDIF), or into the hardware router or mixer. Your application software may break each of these stereo devices down further to “left” and “right” mono devices. Therefore you may see them as “Left WavOut 1/2 Delta-66, Right WavOut 1/2 Delta-66”, or “Left WavOut S/PDIF Delta-66, Right WavOut S/PDIF Delta-66”, etc. from within your music software. Most software will handle the outputs as stereo pairs but allow you to pan audio left or right within the pair. Therefore to send a mono output to OUT1 (for example), choose WavOut 1/2, then pan that track hard left.

Note that each device name begins with “WavOut.” This is to remind you that these are software devices, and not always connected directly to output hardware. Instead they are connected to the Delta 66’s internal patchbay/router and may be sent to one of several destinations. For more on the patchbay/router, see the Patchbay/Router section of the Delta Control Panel software discussion.

MACINTOSH SOUND MANAGER INPUTS AND OUTPUTS: The Apple Sound Manager limits the user to one stereo pair for input and one stereo pair for output. Within your music software, the device selection when using the Sound Manager

13

drivers for input and output will be “Sound Manager” both for input source and for output port.

To select the Sound Manager driver, open the Apple Menu and go to Control Panel | Sound. For both “Sound In”and “Sound Out,” click and highlight the Delta icon, then exit. You may select which Delta hardware stereo input pair and stereo output pair will be used for the Sound Manager’s Sound In and Sound Out in the Delta Control Panel “Hardware Settings Page” (see section, “Hardware Settings Page”under “Delta Control Panel”). Whichever stereo pair you select, the software input and output device selection within your music program will remain the same.

ASIO DRIVER INPUT DEVICES: When using the ASIO audio drivers with programs that support ASIO-style audio, the input devices are displayed as mono devices. Within ASIO software applications, the names of the Delta 66 audio input devices are:

Analog In1 Delta-66

Analog In2 Delta-66

Analog In3 Delta-66

Analog In4 Delta-66

S/PDIF In L Delta-66

S/PDIF In R Delta-66

Mon.Mixer L Delta-66

Mon.Mixer R Delta-66

Notice the S/PDIF In and Monitor Mixer names include “L” and “R” characters. “L” indicates the left channel of the stereo stream, while “R” indicates right channel.

ASIO DRIVER OUTPUT DEVICES: The Delta 66’s ASIO output devices appear in stereo pairs. Because each device is stereo, you may see “left” and “right” references within your software application. This allows the application to pan audio left and right under software control. To send a signal to a Delta ASIO output 1 (for example) as a mono output send, one would choose “Analog 1/2 Delta-66” for that track’s output port, and then pan that output hard left. The ASIO outputs are named as follows:

Analog 1/2 Delta-66

Analog 3/4 Delta-66

S/PDIF L/R Delta-66

WINDOWS MULTIMEDIA SETTINGS: Windows may be set up to use the Delta 66 as its default audio device, allowing system sounds to be sent out the Delta 66. This also enables you to use the Delta 66 with the sound applets included with Windows. To set this up, go to Control Panel | Multimedia. In the Audio Properties page, set the Playback and Recording devices to the Delta 66 input and output devices of your choice.
