CONTROLS AND FUNCTIONS
Remote Sensor
This sensor receives the signals from the handheld remote control.
Power/Mute Selector
This dual function momentary switch turns the 28K on, off or mutes
the outputs.
Power/Mute Indicator
This LED will illuminate blue when the 28K is in the operating mode and will
flash when in the mute mode.
Volume Control
This motorized volume knob controls the overall preamp output level.
Balance Control
This motorized balance knob controls the left/right volume balance.
Listen Selector
This control determines what source is being routed to the preamp outputs.
Record Out Selector
This control determines what source is being routed to the record outputs.
Inputs
These are line level inputs for your sources. The top row is for the left channel
and the bottom row for the right channel.
Tape Outputs
These are fixed level outputs for use with recording devices.
Preamp Outputs
These are variable level outputs for use with your power amplifier.
+5VDC Output
This mini jack connector is for the optional RPC 120 power controller.
A/C Power Connector
This three-prong connector is for the A/C power cable.
SYSTEM SETUP AND OPERATION
Inputs
Before inserting or removing any connectors, be certain both the preamp and
power amp are OFF. Using the appropriate RCA cables, connect your source
to the corresponding input on the rear panel. The audio output of a video
source can be connected to any input. Consult your Aragon dealer for
recommendations on RCA cables.
Outputs
Connect the input of your tape recorder to the tape output on the back panel
of the preamp. Connect the input of your power amp to either preamp output
connector. Two preamp outputs are provided to facilitate the use of two power
amps or a subwoofer (if desired).
A/C Input
After you have finished with all of your input and output connections, plug the
female end of the provided A/C line cord into the three-pronged IEC socket on
the rear panel. Plug the optional RPC 120 power controller into the +5VDC
control output on the back of your 28K. When connected, this will allow you to
turn on/off your entire audio system by simply turning on/off your 28K. The A/C
switching is performed externally to eliminate the additional noise associated
with high current A/C power in proximity to the sensitive analog circuitry.
Power/Mute Selector
When the Power/Mute switch is rotated clockwise to the power position, the
LED will flash blue for approximately three seconds (initializing) and then turn
solid blue, indicating that the preamp is operating. Rotating the switch
clockwise with the 28K on will shut the preamplifier off and the LED will go out.
With the 28K on, rotating the switch counterclockwise to “Mute” will mute the
preamp outputs (not Record) and the LED will flash. In all cases, even if the
power is off, an idle current is passed through the sensitive analog circuitry to
maintain proper operating temperature for optimum sonic quality.
Volume and Balance Controls
To increase the volume, rotate the volume control clockwise. At any given
position, the actual volume may differ from source to source due to the differ-
ent output levels of the different sources. Prior to changing the source or
recording, we suggest you fully lower the volume control and readjust to the
desired listening level. When in mute mode, the volume of your 28K can be
turned down, but not up, via the remote control. This safety feature is to pro-
tect the speakers from source material volume changes. When adjusting the
balance, rotating the balance control clockwise from its center position will
decrease the output of the left speaker. Rotating the balance control counter-
clockwise will decrease the output of the right speaker.
Listen and Record Controls
The 28K allows you to listen to one source while recording another. By rotating
the “listen” knob, you select the source for listening. Clockwise from the left,
the sequence is: TAPE 1, TAPE 2, AUX, TUNER, D/A, CD. By rotating the
“record” knob, you select the source you wish to record from. Clockwise from
the left, the sequence is: CD, D/A, TUNER, AUX, TAPE 2, TAPE 1.
