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.
aptX™ HD Bluetooth Connection 8
8
The Bluetooth Antenna on the S14'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 S14 / 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 S14 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. The
maximum support size of the USB flash drive is 32 GB. 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 S14 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 S14.
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 S14.
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.
