It should not be necessary to reboot your computer once the GCHA is connected, however, ﬁ rst time users of the GCHA may need to reboot or otherwise instruct the computer to install the new USB device if the unit does not install automatically when plugged in.

Once the system recognizes the GCHA as the USB sound device, it will be necessary to make sure the computer’s internal volume control is turned up all the way. On most Windows XP systems, look for the small speaker icon in the lower right hand side of the computer’s screen in an area known as the System Tray. If the icon is not visible, follow these instructions: go to Start -> Settings -> Control Panel. Open the Windows Control panel.

From the Control Panel, choose Sounds, Speech and Audio Devices. Open this dialog box and adjust the system volume all the way up. If you do not adjust the system volume up, the GCHA may not have enough volume to satisfy your listening requirements. WAV and CD should be up as well.

You may have to tell the computer to make the GCHA the default USB device, althought typically this will happen automatically. The GCHA is recognized by the computer as USB Speakers or USB Composite Device. Go to Start -> Settings -> Control Panel. Open the Windows Control panel. From the Control Panel, choose Sounds, Speech and Audio Devices -> Choose Sounds and Audio Devices -> Choose Audio -> Choose USB Speakers as the default device.

At this point, you can place a CD or DVD (if your computer has a CD or DVD drive built in) into your computer’s disc drive and it should play automatically through the GCHA once you turn the volume control on the GCHA to a reasonable level. You can also play music recorded on your computer’s hard drive, using a program like Windows Media Player to select the music, or stream live sound via Real Time Player.

The GCHA will automatically choose the digital USB input if there is a signal present. Once the Windows Media Player or the CD or DVD player, built into the computer, is stopped, the GCHA should switch back to the analog audio inputs.

At this point you should be ready to enjoy the beneﬁ ts of high end audio played through the GCHA Headphone Ampliﬁ er.
