ROTEL RA-1062 - Manual (Page 8)

12V TRIGGER Connection
Several Rotel amplifiers can be turned on and
off using a 12 volt signal, provided by the 12V
TRIGGER connection. When the RA-1062 is
activated, a 12 volt DC signal appears at this
connector and will turn on an amplifier. When
the RA-1062 is turned off, the trigger signal
is interrupted and the external amplifier will
be turned off.
Audio Controls
The following controls are used to operate
the RA-1062.
VOLUME Control
Turn the front panel VOLUME control clockwise
to increase the volume, or counterclockwise to
decrease the volume. Alternatively, press the
VOL buttons on the remote control to adjust
the volume up or down
BALANCE Control
The Balance Control adjusts the left-to-right
balance of the sound output. Normally the
control should be left in the center position.
In some situations, typically when the main
listening position is not ideally centered be-
tween the speakers, it may be necessary to
adjust the control to achieve proper left-to-right
balance. Turning the control counter-clockwise
shifts the sound balance to the left. Turning
the control clockwise shifts the sound balance
to the right.
CONTOUR Selector
Instead of conventional tone controls, the RA-
1062 has a front-panel CONTOUR control
which selects one of five available settings.
Each setting provides a fixed frequency contour
as follows:
OFF: the tone contour circuits are bypassed
to ensure the purest possible sound.
L-1: moderate increase in bass frequencies
(typically +3dB at 100Hz).
L-2: more increase in bass frequencies (typi-
cally +4dB at 100Hz).
H: moderate increase in high frequencies
(+3dB at 10kHz).
LH: combination of L-2 bass and H high
frequency increases.
LISTENING Selector
The setting of the LISTENING selector controls
which of the input signals goes to the main
outputs and onto the power amplifier – or,
more simply, which source is heard. Turn the
front panel control to the source you want to
hear, or press the corresponding button on the
RR-AT94 remote.
RECORDING Selector
The RA-1062 can record from any input source
(except TAPE 2) to a recorder connected to TAPE
1 or TAPE 2 outputs. To select an input source
for recording, turn the RECORDING control on
the front-panel to the desired source.
This selection is independent of the source
selected for listening. While recording, you
may still select a different source using the
LISTENING selector.
If you have a three-head recorder or a DAT
recorder that allows simultaneous read and
write operation, you can monitor your recording
by setting the LISTENING switch to the TAPE 1
or TAPE 2 position.
NOTE: If you select TAPE 1 with the RE-
CORDING control, the recording signal will
only be available at the TAPE 2 recording
outputs, not the TAPE 1 outputs. To dub a
tape, select TAPE 1 and record to the tape
deck connected to the TAPE 2 outputs.
MUTE Button
To temporarily mute the sound of the system
press the MUTE button on the RR-AT94 remote.
Press the button again to return the sound vol-
ume to the original level. The LED in the volume
control will flash when the unit is muted.
PHONES Output
The PHONES output allows you to connect
headphones for private listening. This output
accepts standard stereo phone (1/4”) plugs.
If your headphones have another type of plug,
such as a 1/8” mini-plug, you will need an
adapter plug. Contact your authorized Rotel
dealer, to get the correct adapter plug.
NOTE: Plugging in headphones does not
cut off the signal to the speakers. If desired,
use the SPEAKERS selector to turn off the
signal to the speakers for private listening.
SPEAKERS Selector
A four-position rotary switch on the front panel
determines which set of speakers, if any, is ac-
tive. Set the SPEAKER selector as follows:
OFF: No speakers will be heard. Use this
position when listening to headphones.
A: The speakers connected to the SPEAKER A
terminals will be heard.
B: The speakers connected to the SPEAKER B
terminals will be heard.
A+B: The speakers connected to both the
SPEAKER A and SPEAKER B terminals will
be heard.
Protection Circuit
A thermal protection circuit protects the ampli-
fier against potential damage in the event of
extreme or faulty operating conditions. Unlike
many designs, the RA-1062’s protection circuit
is independent of the audio signal and has
no impact on sonic performance. Instead, the
protection circuit monitors the temperature of
the output devices and shuts down the amplifier
if temperatures exceed safe limits.
Should a faulty condition arise, the amplifier will
stop playing. If this happens, turn the amplifier
off, let it cool down for several minutes, and
attempt to identify and correct the problem.
When you turn the amplifier back on, the
protection circuit will automatically reset.
