polarized wall outlet. Do not use an extension cord. A heavy duty multi-tap
power outlet strip may be used if it (and the wall outlet) is rated to handle
the current demanded by the RA-1592MKII and all the other components
connected to it.
If you are going to be away from home for an extended period of time
such as a month-long vacation, it is a sensible precaution to unplug your
amplifier (as well as other audio and video components) while you are away.
POWER Switch and Power Indicator
1
Press the front panel Power Switch button, to turn the unit on. The Power
Indicator light is illuminated when the unit is on. Press Power Switch button
again to turn the unit off.
When the power switch is in the ON position, the remote control ON and
OFF buttons may be used to activate the RA-1592MKII. In Standby mode
the power LED remains lit, but the display is turned off.
NOTE:
Place the self adhesive ring over the light surrounding the Power
switch if the blue light is too bright.
12V TRIGGER Connection
r
See Figure 4
Some audio components can be turned on automatically when they receive a
12V turn on signal. The two 12V Trigger Outputs of the RA-1592MKII provide
the required signal. Connect compatible components to the RA-1592MKII
with a conventional 3.5mm mini plug cable. When the RA-1592MKII is in
turn off mode, the trigger signal is interrupted, so the components controlled
by it are turned off.
Input Signal Connections
NOTE:
To prevent loud noises that neither you nor your speakers will
appreciate, make sure the system is turned off when you make any
signal connections.
Phono Input
u
and Ground Connection (GND)
See Figure 3
Plug the cable from the turntable into the appropriate left and right phono
inputs. If the turntable has a “ground” wire, connect it to the screw terminal
to the left of the Phono inputs. It will help prevent hum and noise.
Line Level Inputs
u
See Figure 3
The CD, Tuner, and Aux inputs of the amplifier are analog “line level” inputs.
These inputs are for connecting components such as CD players or other
audio playback devices with an analog audio output.
The left and right channels are clearly labeled and should be connected to
the corresponding channels of the source component. The Left connectors
are white, the Right connectors are red. Use high quality RCA cables for
connecting input source components to the RA-1592MKII. Ask your authorized
Rotel dealer for advice about cables.
Balanced (XLR) Inputs
p
See Figure 5
A pair of balanced XLR inputs accept audio signals from CD player, Blu-ray
player or other source components with XLR outputs.
NOTE:
You should choose only one method of analog connection from
a source component to RA‑1592MKII. Do not connect both the RCA and
XLR outputs of a source component to the RA‑1592MKII at the same time.
Digital Signal Inputs
-
See Figure 4
There are three sets of digital inputs labeled 1, 2 and 3, for COAXIAL and
OPTICAL respectively. Connect the COAXIAL or OPTICAL PCM outputs of
your source component into these sockets. The digital signals will be decoded
and played by the RA-1592MKII. The unit is capable of decoding PCM
signals up to 24 bit, 192kHz.
Output Connections
MONO SUB Output
i
There are 2 connectors for mono subwoofer output to connect to a subwoofer.
These mono outputs are summed with both the left and right audio signal.
They are parallel outputs allowing 2 subwoofers to be connected to the
RA-1592MKII.
Preamp Output
o
The RA-1592MKII has a set of preamp outputs labeled PRE OUT. The currently
selected source input is available from this output. Typically the PRE OUT
output is used to provide a signal to another integrated amplifier or power
amplifier, which is used to drive remote speakers.
NOTE:
Changes to the settings of the Volume, Balance or Tone controls
affect the signal from the Preamp Output.
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.
Speaker Outputs
]
See Figure 3
The RA-1592MKII 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-1592MKII. See
your authorized Rotel dealer if you have any questions.
Speaker Wire Selection
Use insulated two-conductor stranded wire to connect the RA-1592MKII to
the speakers. The size and quality of the wire can have an audible effect
