    Verifying Delta Installation In Windows, open the Windows Control Panel (do so via Start | Settings | Control Panel ). If your Delta 44 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.

    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. Semi-pro 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.

  • Page 12: Synchronization

    Synchronization For proper operation, the entire Delta 44 system is always synchronized to a single master clock. This master clock is derived from the internal crystal oscillators. 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.
  • Page 13 each of these stereo devices down further to “left” and “right” mono devices. 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.

    Analog 1/2 Delta-44 Analog 3/4 Delta-44 WINDOWS MULTIMEDIA SETTINGS: Windows may be set up to use the Delta 44 as its default audio device, allowing system sounds to be sent out the Delta 44. This also enables you to use the Delta 44 with the sound applets included with Windows.

  • Page 15: Monitor Mixer Page

    Monitor Mixer Page The Monitor Mixer is the first page that appears when the Delta Control Panel is opened, and controls the digital mixer built into the Delta 44’s PCI controller chip. As described in previous sections, the output of this mixer may be assigned to the OUT1/OUT2 analog outputs.

The green section represents a safe zone, ranging from approximately -48dB to -12dB. Most audio signals should appropriately fill this section of the meter. The yellow section ranges from -12dB to -3dB as the signal approaches a ‘hotter’...

    PAN: Each mixer input is considered “mono” and may be individually panned anywhere in the stereo output mix. A pan control is positioned directly under each input channel peak meter and has the appearance of a small vertical pointer. To make a coarse adjustment, click on the pan control with your mouse and drag it to the desired position.

    Delta 44 Recording Tutorials In this section we will explore two sample setups for recording and playback using the Delta 44 Digital Recording Interface. This is by no means an exhaustive tutorial but its intent is to help you understand most of the Delta 44’s feature set. Before beginning, you should open your music software and profile the Delta 44, enable its drivers, or otherwise setup the software for operation with the Delta 44.
  • Page 24 NOTE: Because improper connections may potentially make very loud noises, it’s a good idea to have all monitor levels set low or muted while hooking up audio equipment — you may even choose to turn your computer off before making the connections. 1.
  • Page 25 5. Click on the Delta Control Panel on your Windows taskbar to maximize it. Click on the ‘Hardware Settings’ tab. 6. Under “CODEC Sample Rate,” verify that the “Rate Locked” checkbox is not activated. This will allow your application software to set the Delta 44 sample rate as it pleases.
  • Page 26 Select the “Monitor Mixer” tab of the Delta Control Panel. The default Master Volume fader settings are 0dB and un-muted, and all other faders are set to full attenuation (-144dB) and muted. We will need to adjust these to our preference. The screen capture below shows the settings that we wish to achieve.
  • Page 27 Now is the time to launch your music software and set it up to record and playback audio tracks. We’re going to speak in general terms here, since setup within software programs will vary somewhat. Minimize your Delta Control Panel so that you can easily access it from your Windows taskbar.
  • Page 28 playback levels of your guitar and mic. Adjust the faders and mute controls so that you may hear the guitar and mic at the appropriate levels and mix. These are the levels at which you may monitor the pre-recorded tracks while you overdub (record other tracks while listening to the first) additional parts.

  • Page 29: Typical Setup #2

    Notice that if we continue to overdub past track 4, we run out of WavOut devices to assign to. In this case, you may want to do some of your level mixing within the software application if it supports it. Most applications will allow you to assign more than one track to an output device and then set the relative levels of the tracks within the software, letting the software do the mixing.
  • Page 30 1. Plug the microphones into the mic inputs 1 & 2 of the pre-amps. Plug the guitars into the high impedance inputs 3 & 4 of the pre-amps. 2. Plug the outputs of the pre-amps 1-4 into the hardware inputs 1-4 of the Delta 44. Usually pre-amp outputs are balanced, so if they are, use TRS cables and set the Delta +4/Consumer/-10 input switches to the +4dB setting in the Hardware Settings page of the Delta Control Panel.
  • Page 31 6. Minimize the Delta Control Panel to the Windows taskbar. 7. Open your music software program. Set up four tracks for recording: Track one — Track two — Track three — Track four — 8. Now we want to set up the output ports for the four tracks. Track one —...

    this were a real recording situation and you wished to add other instruments as overdubs, you might want to combine recorded tracks to one stereo pair of outputs (WavOut 1/2 Delta-44, for example). This would ‘free up’ several channels for monitoring the overdubs.

After returning to Windows, follow the steps outlined in the “Verifying Windows Driver Installation” section of this manual. It might take more than one PCI slot relocation to find an open IRQ.
  • Page 34 Typically, if you move one of the conflicting cards to another PCI slot, an IRQ conflict will disappear. Address conflicts are rare amongst PCI devices, but if there is no obvious IRQ conflict, why not check for I/O Address conflicts while in the Device Manager?

  • Page 35: Troubleshooting Tips For Frequently Asked Questions

    Troubleshooting Tips for Frequently Asked Questions Problem: No Sound. Possible Cause 1: The Delta 44 hardware or software device drivers are not properly installed. See the installation sections of this manual for further information. Possible Cause 2: There is a resource conflict between the Delta 44 and another device in your computer.

  • Page 36: Appendix A - Technical Specs

    Possible Cause 3: Some accelerated graphics cards use excessive amounts of system bandwidth, preventing the recording buffer of an audio card from keeping up with demand. This can cause clicks in the recording. Reducing or turning off the graphics card’s graphics acceleration feature often resolves this problem.

  • Page 37: Appendix B -If You Use An External Mixer

    Appendix B -If You Use An External Mixer... Our main objective is to get the signal we want to record to the Delta 44, and to monitor the outputs from the Delta 44. The Delta 44 has a mixer contained in its PCI chip that allows you to mix hardware inputs and software outputs and send it to an analog stereo output pair.
