Power is available on channels 1 through 10.
3. Main Out XLR / 1/4 jacks
The Main Out left and right XLR and 1/4-inch jacks are located on the rear panel. These are
true low impedance balanced outputs. For the best noise immunity use well shielded cables.
4. Zone Out Jack
The Zone Out phone jack on the rear panel is a TRS (balanced tip ring sleeve configu-
ration) output jack. Use it to connect to balanced and unbalanced audio inputs.
5. USB Input/Output
To your computer, the VGM14’s USB connection appears like a standard “USB Audio
CODEC.” The VGM14’s USB output is fully USB 2.0 compliant; you can use it to connect
directly to one of the USB ports on your computer. The connection to the computer pow-
ers the USB circuitry inside the VGM14.
Since the VGM14’s USB buss delivers high quality digital audio to (and from) your com-
puter, as well as bus powering the USB interface, we suggest the use of a high quality,
shielded, USB cable for best performance. Ideally, you should connect directly to one of
the USB ports on your computer.
Since c onnecting throu gh a USB hub can reduce power and bandwidth for each USB
device connected, t his should be avoided when possible.
The VGM14 USB is compatible with USB 1.1 and 2.0 interfaces but USB 2.0 is preferred for
the cabling and computer connection as it makes better use of system bandwidth. If you
must use a hub, it should be a powered USB 2.0 compliant hub; this is especially important if
you plan to use multiple units for more channels of simultaneous digital audio input.
You can use both RCA output jacks and the USB Out at the same time, which is handy
when you want to run to a computer and to a local source monitor.
On the rear panel is a USB standard B connector. Use a USB standard A to standard B
cable to connect the VGM14 to your computer.
Once the USB connection is made and your computer is on, the VGM14 USB interface
circuitry is powered by your computer over the USB bus and the unit will automatically
connect and try to set your computer “Default Audio Device” to be “USB Audio CODEC”.
Usually the computer will do this automatically whenever a USB device is first connected,
but it is sometimes necessary to make the selection manually.
These settings should be made while the two units are connected. Select one of the fol-
lowing sound recording (input) settings:
