RA‑1592MKII Stereo Integrated Amplifier
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 amplifier 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 amplifier connection.
Speaker Connections
]
Turn off all the components in the system before connecting the speakers.
The RA-1592MKII 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 RA-1592MKII 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. Place
the connector lug or wire around the binding post shaft. Turn the binding
post 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.

The front USB input can be connected to an iPhone, iPad or iPod device
providing music playback to the amplifier. To enable audio playback using
one of these devices simply plug the device into the front USB and select
USB as the desired source. The iPhone, iPad and iPod device will remain

The Bluetooth Antenna
0
on the RA-1592MKII’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 Bluetooth” and connect to it.
Connection is normally automatic, but if prompted for a password, please
