Power, Ground and Turn-On Connections
The X2 850.3 features a terminal block that is designed to
secure 4 AWG power and ground connections to the amp. We
recommend the use of pure copper power and ground wires in
order to achieve the most reliable connections. Also, be weary
of 4 gauge versus 4-AWG wire. The American Wire Gauge
(AWG) is a universal standard that specifies the diameter of
stranded conductors. Wiring that is labelled as '4 gauge' may
not be adequate to supply the amp with the current it requires
to operate reliably and efficiently.
The Turn On input should be connected to the amplifier +12V
DC remote turn-on output of your after-market source unit. In most cases this is a blue wire with a white stripe. Note: On
some source units, there are power antenna AND remote turn-on wires. If you only hear audio when listening to the AM/
FM tuner, your amp may connected to the wrong wire.
Fuses
The X2 850.5 includes three 30 amp ATC/ATO fuses on the
left side of the end-panel. These fuses exist to protect the
internal circuitry of the amplifier from damage and are not a
replacement for a proper fuse at the battery in your vehicle.
Under no conditions should you increase the value of the
fuses used in this location.
If the fuses blow immediately upon insertion, contact your
authorized ARC Audio dealer or the Technical Support
department at ARC Audio for assistance.
Auto Sense Turn-On Detection
The X2 850.5 features two Auto-Sense Turn-On modes. In
DC Detect mode, the amplifier monitors the Channel 1 RCA
input for the presence of a DC offset voltage (common with
Bridge Tied Load (BTL) source units and amplifiers). When
this DC voltage is present, the amp will turn itself on.
When set to Signal Detect, the X2 850.5 monitors the
Channel 1 RCA input for the presence of an audio signal.
When an audio signal is present, the amp will turn itself on.
The amp automatically turns off 10 seconds after the DC
Detect or Signal Detect no longer sees an appropriate signal.
When using either Auto-Detect mode, only the Channel 1
input is monitored.
The Turn On input on the power terminal block is NOT
used when Auto Detect is turned on.
Remote Level Control
The X2 850.5 ships with a remote level control that can
be installed near the driver's seat so the owner can adjust
the level of a subwoofer. The level control only affects the
Subwoofer channels of the amplifier.
To set the gains on this amplifier, either leave the Remote
Level Control disconnected or turn it to it's maximum setting
(fully clockwise) during configuration. The Remote Level
Control functions as an attenuator so as not to alter the gain
structure of the amp and cause distortion, unlike a remote
bass boost control.
