Innovation
The ARX BarMIX is a unique ?user-friendly? Zoner/Mixer, enabling a
choice of four stereo audio sources to be routed to each of two zones.
Intuitive Layout
The linear ergonomic flow of the front panel controls, coupled with the
visual feedback of level settings and source selection makes using the
BarMIX totally intuitive, even for casual staff with no prior experience.
Up to four stereo sources can be connected to the BarMIX, such as:
Tape/cassette/DVD/CD decks, TV/Satellite/video audio, Juke Box/Karaoke
systems. Interlocking switches for each source ensure that there is no
risk of accidentally selecting two sources for the one zone.Each switch
has an associated status LED for easy at-a-glance confirmation of which
program source is active, and numbered panels above each switch let you
label each source.The BarMIX has provision for connecting a microphone,
to allow announcements to made in the zones. There is comprehensive 3
way EQ and an individual level control for the microphone on the front panel,
as well as a Gain trim control on the rear.Front panel switches turn the
microphone on for each zone, and there is also provision to connect a push-
to-talk signal for priority/evac override.
Control Options
Each of the two output zones has the option of being controlled Locally, ie
from the control on the unit itself, or Remotely, with the optional BM-1 VCA
Remote Level Control pack (See Right) Fitting this option will disable the front
panel control. A front panel LED indicates if this option is fitted and active.
This is useful if the unit needs to be mounted some distance away from where
it is likely to be controlled.For example, the BarMIX unit may be installed alongside
other audio equipment in an equipment room, while the Remote can be located
somewhere convenient - behind the bar, for example.From a security point of view,
or where volume can be a neighbour problem, this option provides ultimate over-riding
level control well out of the way of prying fingers!From a security point of view, or

level control well out of the way of prying fingers!
Zone Setup
On the rear, each input source has a Left and Right phono (RCA type) input and an
associated Gain trim control. This allows level matching of all four sources, so there
is no need to reset the Zone output levels when switching between sources.
Each Zone has Left and Right Balanced XLR outputs, plus dual LED meters show output
levels for each zone.
Universal AC Power
AC power is a universal 100 to 120V or 220 to 240V, and is connected to the unit via a
removable power lead and standard 3 pin IEC connector, with built in fuse and voltage
selection switch.
The intuitive layout and precise control offered by the ARX BarMIX make it the ideal choice
for any Zone mixing installation application.
