RA‑1592 Stereo Integrated Amplier
Speaker Outputs
]
See Figure 3
The RA-1592 has two sets of speaker outputs, labeled SPEAKER A and
SPEAKER B. The speaker outputs are controlled by the A-B speaker selector
buttons
7
on the front panel and the buttons
K
on the remote control.
Speaker Selection
If only one set of speakers will be used at any given time, the speakers may
have an impedance as low as 4 ohms. If there are times when both the A
and B speakers will be used, all the speakers should have an impedance
of 8 ohms or more. Speaker impedance ratings are less than precise. In
practice, very few loudspeakers will present any problems for the RA-1592.
See your authorized Rotel dealer if you have any questions.
Speaker Wire Selection
Use insulated two-conductor stranded wire to connect the RA-1592 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 amplier 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 amplier connection.
Speaker Connections
]
Turn off all the components in the system before connecting the speakers.
The RA-1592 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-1592 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 rmly in place.
NOTE: Be sure there are no loose wire strands that could touch adjacent
wires or connectors.
Headphone Output
5
The headphone output allows you to connect headphones for private listening.
This output accepts a standard 3.5mm (1/8”) mini stereo headphone
connector. Plugging in a set of headphones does not cut off the signal to
the speakers. Use the front panel
7
or remote control
K
A-B Speaker
Selector to turn off the speakers.
NOTE: Because the sensitivity of speakers and headphones can
vary widely, always reduce the volume level before connecting or
disconnecting headphones.
Remote Sensor
2
This remote sensor window receives IR commands from the remote control.
Please do not block this sensor.
Display
3
The front panel display shows the source selected, volume level and tone
settings. The display provides access to the setup and conguration menu
options of the amplier.
Front USB Input
6
See Figure 6
The front USB input can be connected to an iPhone, iPad or iPod device
providing music playback to the amplier. 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 device remain active allowing search and
play functions.
APTX Bluetooth Connection
0
The Bluetooth Antenna 0 on the RA-1592’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
press “0000” on your device. The RA-1592’s supports both traditional
Bluetooth and APTX Bluetooth audio streaming.
Audio Controls
VOLUME Control
4
D
Turn the knob clockwise to increase the volume, or counter clockwise to
decrease the volume. From the remote control press the volume + or - button
to turn the volume up or down. Press the MUTE E button to completely
mute the volume.
BALANCE Control
9
C
The Balance Control adjusts the left-to-right balance of the sound output. The
factory default is the center position or “0”. To change the balance from
the front panel, press the MENU
9
button to toggle the front display to
BALANCE SETTING mode. Then press the - or + buttons on the front panel to
change the value to LEFT or RIGHT. The value can change from L15 to R15.
