A properly setup high-performance audio system produces the most natural
sound with little or no adjustment of the tone controls. Use these controls
sparingly. Be particularly careful when turning the controls up. This increases
the power output in the bass or treble range, increasing the load on the
amplifier and speakers.

on the tone control. To turn on tone control, refer to previous section
Tone Control Bypass.

B button
See Figure 4
Connect this input using the supplied USB cable to the PC-USB socket of
your computer.
The A12 supports both USB Audio Class 1.0 and USB Audio Class 2.0
modes. Windows computers do not require installation of a driver for USB
Audio Class 1.0 and support playback of audio up to 96kHz sampling
rates. The Factory Default setting is USB Audio Class 1.0.
To take advantage of USB Audio Class 2.0 audio playback supporting up to
192kHz sampling rates you will need to install the Windows driver supplied
on the CD included with the A12. You will also need to switch the A12 to
USB Audio Class 2.0 playback mode with the following:
• Press MENU on the front panel until "PC-USB CLASS" appears on the display.
• Select "2.0" using the "+" button.
• Power cycle the A12 and reboot your PC after changing the USB Audio
mode to ensure both units are properly configured.
Many audio playback applications do not support 192kHz sampling rate.
Please confirm your audio player supports 192kHz audio and you have
192kHz audio files to properly playback this sample rate. Also, you may
need to configure the audio driver in your PC to output 192kHz or your
computer may "down sample" to a lower audio sample rate. For more
information please refer to your audio player or operating system information.
NOTE: USB Audio Class 2.0 requires installation of the Windows PC
8
or remote control
driver on the CD ROM included with the A12.
NOTE: MAC computers do not require a driver to support PC-USB
Audio Class 1.0 or 2.0.
NOTE: Upon successful installation of the driver, you may need to select
the ROTEL audio driver from the audio/speaker setup of your computer.
