EXT REM IN Jack -

This 3.5mm mini-jack receives command codes from industry-standard infrared
receivers via hard-wired connections. This feature could prove useful when
the unit is installed in a cabinet and the front-panel sensor is blocked. Consult
your authorized Rotel dealer for information on these external repeaters and
the proper wiring of a jack to fit the mini-jack receptacle.

Computer I/O Connector =

The RC-1570 can be controlled via RS232 for integration with automation
systems. The COMPUTER I/O input accepts a standard straight DB-9 Male-
to-Female cable.
For additional information on the connections, software, and operating codes
for computer control of the RC-1570, contact your authorized Rotel dealer.
PC-USB Input y
See Figure 5
Connect this input using the supplied USB cable to the PC-USB socket of
your computer.
The RC-1570 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 CD included with the RC-1570. You will also need to switch
the RC-1570 to USB Audio Class 2.0 playback mode with the following:
• Press MENU on the front panel until "PC-USB AUDIO CLASS" appears
on the display.
• Select "2.0" using the "-" key then press "ENTER".
• Power cycle the RC-1570 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 required installation of the Windows PC
driver on the CD ROM included with the RC-1570.
NOTE: MAC computers do not require a driver to support PC-USB
1.0 or 2.0 audio.
NOTE: Upon successful installation of the driver, you may need to select
the ROTEL audio driver from the audio/speaker setup of your computer.
