Introduction Congratulations on your purchase of the Duo, designed and manufactured by M-Audio. The Duo is a complete USB audio solution for your PC or Macintosh computer .
Other aspects of the Duo, including use of the +4/-10 line level switches, phantom power , etc., are also covered in depth. Also, be sure and check out the section, “Optimizing Y our Sytem for USB Audio,“ later in the manual. So, please read on, and enjoy your Duo.
Front Panel: 1. Line Level Input Switch: This switch will set the input line level for the Duo. W ith the switch in the out position, the Duo will operate at a +4dBu line level. Pressing and locking this switch to the in position will set the operating line level to -10dBV .
Back Panel: 1. 9V AC Power Jack: This power jack accepts a 9v AC 1 Amp 2.5mm power supply . This power supply is included with your Duo, and ONL Y the proper supply should be used. 2. USB Connector: This jack accepts the device-end of a standard USB cable.
Bottom of Unit: At the bottom of the unit are two DIP switches that will set the sampling rate while the Duo is used in standalone mode. The Duo can be used as an A/D converter independent of the computer , using either the line inputs or the mic preamp inputs.
The Duo can be used with the Sound Manager on the Macintosh, or with the W indows Sound System in W indows, and therefore can operate as your system sound card. If your software is ASIO or EASI compliant, such as Steinberg’ s Cubase or Emagic’ s Logic , we suggest using the ASIO or EASI drivers.
6. Y ou will then see W indows 2000 detect and automatically install the driver for the USB Composite Device. 7. W indows will detect and automatically install a number of drivers. As it does this, it will show the "Digital Signature Not Found" Dialog a few times.
driver . Note: If the "USB Composite Device" has already been installed then W indows will skip this step. This will occur if a USB audio device had previously been installed in your system. 3. W indows will report that “USB Duo New Har dware” was found.
Double click on the Installer program. The Installer program installs all Duo extensions, and installs the ASIO driver in a folder named “Duo ASIO”on your desktop. 2. locate the program’s ASIO folder (it will be found within the pr ogram’s folder on your Macintosh HD).
speakers, or a headphone amplifier , or to the inputs of a mixing console. Again, check your device’ s documentation for information on its operating line level, and see the section, “Using the Input and Output Level Switches.
jacks. Check your source or target device’ s documentation for more information on its operating line level. Using the Mic Inputs The Duo gives you two completely independent channels of high gain, ultra low noise pre-amps. Each channel provides low impedance microphone inputs on XLR connectors with optional phantom power .
Phantom Power Unlike dynamic microphones, many "condenser microphones" need to receive a DC voltage (generally 48v) from an external source before they can generate an output signal. If the condenser mic doesn’ t come with its own power supply , then phantom power must be applied from the pre-amp.
at either the Mic Inputs or the Line Inputs of the Duo. Y ou will, however , not be able to hear the software outputs fr om your computer in this case, so this option may only be useful to you when laying down your first r ecorded tracks, i.e., when there is no other audio playing back from your computer .
The USB Audio Configuration Manager , when it is first installed, defaults to the “ASIO/EASI” setting. If you are using an ASIO compliant program such as Steinberg’ s Cubase or Nuendo, or a program that uses “EASI” drivers such as Emagic’ s Logic, then you should leave the configuration manager set to “ASIO/EASI.
3. Power down the Duo, then power it back up. This will reinitialize the Duo. 4. Go to Start | Settings | Contr ol Panel | Multimedia, and set the playback (and recor d) device to “USB Audio Device.
automatically during the normal installation procedure. The USB Audio Configuration Manager defaults to ASIO/EASI operation, so there’ s no need to change any settings there.
T o launch the ASIO or EASI control panel from the USB Configuration Manager: 1. Double click the M-Audio logo in your W indows System T ray , located on the right side of your W indows T askbar . (Y ou can also right-click the icon, then choose “Open M-Audio USB ASIO/EASI Control Panel.
a selection. At the 24-Bit/Sample setting, both stereo input and output pairs are also available. The maximum sample rate will still be 48000 Hz. W ith both stereo pairs enabled at a Bitwidth setting of 24-bits, the Duo will also operate as a 2x2 audio device.
In the M-Audio USB ASIO Driver control panel, to the right of the Bitwidth section, you will see a “Latency” drop-down list that will set the Duo’ s buffer size. A lower latency setting represents a smaller buffer size, with the lower setting being desirable when using the ASIO drivers.
NOTE: When switching the Duo drivers from ASIO use to Sound Manager use, after exiting the ASIO program it is necessary to reinitialize the Duo for use with the Apple Sound Manager . T o do so, exit your music program, then simply power down the Duo and power it back up.
W ith both stereo pairs enabled, i.e., Input 1&2 and Output 1&2, the Duo behaves as a “2x2” audio device at 16- or 24-bits, and at sample rates of 48kHz and below (that is, 48kHz or 44.1kHz). These two sampling rate options as well as bit depths will be selectable from within your music program.
In the Duo Settings control panel, below the Maximum Sample Rate readout, you will see a drop-down list that will set the “Latency” that you will experience while monitoring input through your music program (this is achieved by varying the Duo’ s audio buffer size).
performance. Drives with low seek times that run at a minimum of 7200 RPM are best. • Y ou can’t be too rich or have too much RAM. It’ s a good idea to have at least 128MB, while 256MB or more will greatly enhance performance. T roubleshooting: Problem: No sound.
Problem: I hear a ticking sound along with my audio. Possible Cause1: Use the Duo plugged directly into the computer ’ s USB port. On the other USB port, use only the computer keyboard and mouse with no other USB devices. Possible Cause2: This could be due to an internal device interfering with the USB bus.
Soundcards, Ethernet adapters embedded on the motherboard, or connected via USB, ISA, or PCI. How many PCI/ISA slots do you have and are you using any USB hubs? 3. Are you recording to IDE or SCSI hard drives? These are extremely important pieces of information to know when calling us.
