The MIX 8 from ARX is the ideal real-world interface for today’s 8 track
performance playback requirements, and the solution to all multi channel
line mixing needs. An 8 into 2 stereo line mixer with individual level con-
trols, pan controls, internal RF filters, and a stereo headphone output for
monitoring.
Balanced Inputs and Outputs
Total flexibilty is provided by the inclusion of balanced XLR, unbalanced jack
and phono (RCA) connectors. Each XLR and jack input has up to +6dB of
gain available, while the phono connectors have a nominal input of -10dB
with +16dB of gain available to allow matching of any line level signals.
Individual Pan controls allow accurate signal placement in the spatial field.
All inputs mix down to fully balanced Left and Right Master XLR outputs.
Wide Dynamic Range
Internally, careful attention to the signal path design has resulted in a unit
with wide dynamic range, enough headroom to cope with the hottest line
signal, and excellent noise specifications.
Universal AC Power
AC power range is a universal 100 to 120V or 220 to 240V AC, and is connect-
ed to the unit via a standard three pin IEC connector, with built-in fuse and
voltagechange switch.
Accurate and compact, the MIX 8’s unique combination of ultra low distor-
tion, low noise and high headroom makes it the ideal compact line mixer.
Introduction
Thank you for choosing this ARX MIX 8 Multi-Channel Stereo Line Mixer.
We hope you enjoy using it as much as we enjoyed creating it. As with all
ARX equipment, it has undergone extensive factory calibration and ‘burn in’
before shipping. To ensure continued trouble free use, please familiarise
yourself with the contents of this manual before using the MIX 8.
About the MIX 8
Applications
The MIX 8 has a wide range of applications: as a backing track mixer for live
digital 8 track playback, Broadcast applications, and as an Installation Master
Mixer, allowing all feeds to run independently of each other through the one
speaker system.
Other applications include using it as a line sub-mixer for external effects
units, an Electronic Instruments sub-mixer; in fact, anywhere that multiple
stereo line feeds need mixing, panning and monitoring.
Setting Up
Setting up your MIX 8 is very straightforward and intuitive.
Firstly, make sure all level controls are turned down, then connect the unit to
ACpower.
Please Note:
This is a dual voltage unit. It is essential that you check that the voltage on
the fuseholder cover below the AC connector on the rear of the chassis is set
correctly before connecting it to AC power. See Page 2 for more details on
this.
Connect the signals you wish to mix to the input connectors, and connect the
outputs to the next item in the signal chain; e.g. amplifier, mixer, comp-
ressor/ limiter, equalizer.
Set the Master level controls on the front panel to a low setting, say 7 or 8
o’clock position. Slowly turn up the levels of the individual channels as
required. You can check your signals in the headphones if you are in a low-
noise situation; in that case, leave the Master controls turned down until you
are ready to go.
Extra Note:
The unbalanced RCA (Phono) connectors will need switching on with the
switch on the left hand side of the rear panel if you will be connecting to
them. If you don’t push this switch in, they won’t work.
For the best signal to noise figures, keep the RCA connectors switched off
unless you are using them.
And finally, although you can connect just about any kind of line input to
the MIX 8, you can’t plug a microphone into it. If you need Microphone
inputs, we suggest using our MIXX or MIXXMaster units to plug into the
MIX 8.
