Audio Inputs
We recommend using good quality RCA or XLR inter-
connects to connect the preamp output to the amplifier
inputs. Whenever using the RCA (unbalanced) inputs,
insert the included XLR shorting plugs for optimal gain
and noise performance. Do not connect both RCA and
XLR inputs simultaneously.
Pre-amp On/Off Control (12V Trigger)
To enable an external 2-channel or surround preamp to
automatically power on your Aragon amplifier, connect
the trigger out from the preamp to the the 3.5mm jack
labelled 12V trigger on the Aragon. The jack is wired
with its tip active and will accept a stereo or mono
1/8” (3.5mm) plug.
NOTE: The front panel power button functions
normally even if the trigger input is used.
The Aragon amplifier will automatically
resume control sync with the external preamp
after the next time system power is cycled.
Mains (AC) Power
Your Aragon series amplifier is equipped with a high-
quality 14 gauge, 3-conductor power cord. Plug this
cord into the back of the amplifier and then into a nearby
AC outlet. Avoid using any extension cords or plugging
into other components with rear-panel switched outlets.
If using the amplifier with a power conditioner, ensure
that the receptacle your amplifier plugs into is capable
of providing the full current required by the amplifier.
See section entitled
Technical Specifications, p16
for
a list of current requirements for each model amplifier in
the Aragon series.
It is recommended practice to connect AC
power only after all other connections have
been made.
Control Networks
Ethernet:
In order to take advantage of Aragon En-
hanced Ethernet Control (E2C), connect the Ethernet
port to a 10/100 or faster home network router or switch
port via a standard CAT 5e or newer Ethernet cable. The
network activity indicator near the Ethernet jack illumi-
nates green when network activity is detected.
This port may also be directly connected to a system
controller utilizing Ethernet command protocols. Con-
tact your dealer or Aragon Customer Service in order to
verify compatibility with certain control systems.
RS-232:
Connect this port to a system controller using a
9-pin RS-232 serial cable in order to control and monitor
the amplifier remotely. Contact your dealer or Aragon
Customer Service in order to verify compatibility with
certain control systems.
operation
This section discusses the normal operation of your
Aragon amplifier and highlights the control flexibility
engineered into this component.
Standby Mode
When first connected to AC power, your Aragon ampli-
fier initializes in standby mode. This is indicated by a
red illuminated Status Light. Normally, the initialization
process takes a few seconds. Once the amplifier is
initialized, it is ready to be powered on.
Before powering on, ensure that your preamp
volume level is not too high or else speaker
damage may occur.
Turn on the amplifier by pressing the front panel power
button. If an external trigger input from a preamp is
used, turning on the preamp should automatically turn
on the amplifier. The Status Light turns blue indicating
the amplifier is active. Pressing the power button again
puts the amplifier back into standby mode.
