Verifying Delta Control Panel Software 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. 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

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. NOTE: In order to preserve its high dynamic range and minimize distortion, the Delta 4

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. The Delta 44 supports these sample rates by using either of its internal crystal oscillators and dividing the rate of that oscillator by some value

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. Note that each device name begins with “WavOut.” This is to remind you that these are software devices, and not always connected directly to the Delta 44’s output jacks. Instead they are connected to t

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. To set this up, go to Control Panel | Multimedia. In the Audio Properties page, set the Playback and Recording devices to the Delta 44 input and output devices of your choice. Delta 44 Control Panel Software ON THE PC

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. At the same time, the mixer outputs may be recorded in stereo by software. The Monitor Mixer Page is essentially a collection of volume level faders, audio level (or ‘peak’) meters, and solo/mute controls

that is 12dB ‘quieter’ than full-scale is referred to as “-12dB.” The meters are vertically color-coded into three sections: green, yellow and red. 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’ level. For best capture resolution, recording in this area is both safe and advised. The red section of the

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. For finer adjustment (in 1% increments), you may click on the pan control to make it active, and then use the left/right or up/down cursor keys on your com

MULTITRACK DRIVER DEVICES: The Delta 44 drivers may intelligently synchronize the beginning of recording and playback across all audio devices on the board. When using application software that is capable of using multiple channels simultaneously, select “Single and In-Sync” to ensure that all audio channels will begin playback and/or recording at the same time. Otherwise select “Independent” to allow the audio channels to play independently — this setting may be desirable if more than one app
