AUSTRALIAN MONITOR SM12 User manual

The Australian Monitor Pro Series SM12 and SM16 stereo
console mixers are designed to be compact, ultra low noise and
feature packed.
With a mixture of mono channels featuring balanced XLR or TRS inputs
and switchable 48V phantom power, and stereo channels all boasting
3 stage E0 and pre and postlader auxiliary sends, the SM series
mixers are as versatile as they are cost effective.
The SM Series mixers feature peak LED indication and low cut
filters on all mono channels, high quality 60mm faders and sealed
potentiometers. 19 inch rack mount kit and accurate 10 segment bar
graph meters for the stereo output buss.
The Australian Monitor Pro Series SM12 and SMl6 give the audio
professional a sonically superior mixing console offering a feature set
and versatility usually found in mixing consoles many times their price.

This is the initial gain control for each

inputs level while still leaving headroom
so the input signal does not reach clipping
level. This gain stage has a range from

The channel pan control is used to
position the channel signal in the stereo
field. This differs from the mono channels
as this pan control will determine the level
of either the Left or Right buss that is sent
to the master mix. For example if the pan
control is turned fully clockwise, only the
Right signal path will be sent to the
master mix. lf the Left input only is
connected (a mono signal) the pan control
will work as per the mono channels.

Before connecting any input sources to your SM12 or SM16 stereo
console mixer, please make sure the following initial settings are correct.
. All gain controls and faders are set to minimum
. All Auxiliary sends are set to minimum
. E0 is set flat (i.e. in centre positionl
. Ensure the power supply is correctly connected
. No PFlls are active
Connect mic or line source to desired channel inputs (make sure
phantom power is switched on if required) and ensure Master Outputs
are correctly connected to your audio system.
S S.t tnr Master Output to unity gain (set to "0")
$ furn up the input gain for your selected channel to 12 0'clock

ltl0TE: A lull discussion of setting up a complex system with
correct gain structure is beyond the scope olthis manual.
The procedure above assumes that the installer has
correctly set up external equipment connected to this
mixer prior to initiating the setup procedure.
