USB TO STEREO CONVERTER
The GET OUT is a USB Audio Interface with transformer balanced stereo outputs to avoid hum, noise and earth loops.
The computer connection is via a USB “Type B” connector located on the rear panel and the supplied USB cable. The GET OUT is powered by the USB computer
connection. A pair of male XLR connectors provide line level balanced outputs.
The GET OUT also features a front panel ground lift switch and a level control for achieving the optimal output level.
The GET OUT functions with Windows XP, Windows 7 and Mac OSX operating systems without the need to install drivers. Simply plug and play!
The GET OUT operates as an external sound device for your laptop or PC. The device name is “USB Audio Device” (Windows) or “USB Audio CODEC” (OSX)
Following connection to a computer, Windows will set the mixer volume to 50%. We recommend you adjust this control to 100% in the interest of delivering optimal
signal levels with minimal noise. Simply open the Windows Control Panel, select Sounds and Audio Devices, then select the “USB Audio Device” and set the Volume
slider to maximum.
6 ZONE OUTPUT SWITCHER
The ZONED OUT is a simple way to have up to 6 zone output zone switching in your installation. Simply wire the Zoned out to the constant voltage output of your AMC+
or amp and you have the ability to switch up to 6 speaker zones on or off.
