NOTE: Because the sensitivity of speakers and headphones can
vary widely, always reduce the volume level before connecting or
disconnecting headphones.

Speaker Wire Selection
Use insulated two-conductor stranded wire to connect the unit to the
speakers. The size and quality of the wire can have an audible effect on
the performance of the system. Standard speaker wire will work, but
can result in lower output or diminished bass response, particularly
over longer distances. In general, heavier wire will improve the sound.
For best performance, you may want to consider special high-quality
speaker cables. Your authorized Rotel dealer can help in the selection of
cables for your system.
Polarity and Phasing
The polarity - the positive/negative orientation of the connections - for
every speaker and streamer connection must be consistent so all the
speakers will be in phase. If the polarity of one connection is reversed,
bass output will be very weak and stereo imaging degraded. All wire is
marked so you can identify the two conductors. There may be ribs or
a stripe on the insulation of one conductor. The wire may have clear
insulation with different color conductors (copper and silver). There may
be polarity indications printed on the insulation. Identify the positive and
negative conductors and be consistent with every speaker and streamer
connection.
Speaker Connection
Turn off all the components in the system before connecting the speakers.
The unit has color-coded binding post type speaker connectors on the
back panel. These connectors accept bare wire, connector lugs, or dual
banana type connectors. (Except in European Community countries
where their use is not permitted.)
Route the wire from the unit to the speakers. Give yourself enough slack so
you can move the components to allow access to the speaker connectors.
If you are using dual banana plugs, connect them to the wires and then
plug into the backs of the binding posts. The thumbscrews of the binding
posts should be screwed in all the way (clockwise).
If you are using terminal lugs, connect them to the wires. If you are
attaching bare wires directly to the binding posts, separate the wire
conductors and strip the insulation from the end of each conductor. Be
careful not to cut into the wire strands. Unscrew (turn counterclockwise)
the binding post thumbscrews. Place the connector lug or wire around
the binding post shaft. Turn the thumbscrews clockwise to clamp the
connector lug or wire firmly in place.
NOTE: Be sure there are no loose wire strands that could touch
adjacent wires or connectors.
Display 5
The front panel display shows the current unit status and streaming
source information. Album artwork is also display on supported source
inputs. The display provides access to the setup and configuration menu
options of the unit.

The Bluetooth Antenna
on the RAS-5000's back panel is for wireless
streaming via Bluetooth, from your device (i.e. mobile phones, tablets
or computers). From your device, look for "Rotel RAS-5000 / xxx--xxxxxx
(series number)" and connect to it. Connection is normally automatic,
but if prompted for a password, please enter "0000" on your device. The
RAS-5000 supports traditional Bluetooth, AAC and aptX™ HD Bluetooth
audio streaming.
Rear USB Port q
The rear USB port allows playback of audio from a USB Flash device.
Supported file types include MP3, AAC (mp4), flac, wav and ogg. All files
should be in the root folder of the flash drive and are played back in
sequential order.
PC-USB Input -
See Figure 4
Connect this input using a USB cable to the PC-USB socket of your
computer.
The RAS-5000 supports USB Audio Class 2.0 modes. To use the PC-USB
connection you will need to install the Windows driver supplied on the
USB stick included with the RAS-5000.
Many audio playback applications do not support 384kHz sampling
rate. Please confirm your audio player supports 384kHz audio and you
have 384kHz audio files to properly playback this sample rate. Also, you
may need to configure the audio driver in your PC to output 384kHz 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
driver on the USB stick included with the RAS-5000.
NOTE: MAC computers do not require a driver to support PC-USB
Audio Class 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.
