ART48 - SUBGROUP
Using the Subgroup’s L/R faders(1.), you can control the level of all linked input
units. By depressing the mute button(2.), you can mute this entire sub group without
touching the fader.
If using more than two Subgroups, the first two Subgroup units should be mounted
as above. These are always positioned near the L/R master (with any other
independent “non influenced” input units placed between the sub groups and the
L/R Master).
Any further Subgroup units should be mounted towards the outer edges of the
mixer. The outputs of these units must be connected to either a Stereo In or a
Multiple unit (that can accommodate two sub groups) using stereo jack cables.
These Stereo In and Multiple units should also be positioned near the L/R Master
(together with any independent “non influenced” input channels), so that their signal
can flow directly to the L/R Master.
Set the back to L/R button(3.) to OFF (not depressed), so that the signal will go
through the cables to the Stereo In or Multiple input unit and from there to the L/R
Bus.
Set the Master Side Switch on these subgroups in the same way that you did for
the first two Subgroup units.
Insert plugs(4.)
The insert follows the summing amps of the Subgroup unit. It therefore works for
both the above scenarios: Routing to the L/R BUS (first two Subgroups) and routing
the L/R signal through cables to a separate stereo input unit (when there are more
than two Subgroups).
If the INSERT DIRECT OUT button(5.) is not depressed (i.e. off, white light),
the signal will not be interrupted by the insertion of a phone jack into the Insert
connector. You can connect a simple mono phone jack or a stereo phone jack to
the insert. The unbalanced line signal will be transmitted through the “tip” of the
phone jack.
If the INSERT DIRECT OUT button is depressed (i.e. on, red light), the signal in the
mixer will be interrupted and the insert will work in the usual way. By connecting a
mono jack, you will get the simple output line signal on the “tip”. By connecting a
standard stereo phone jack, you get the (output) signal from the “tip” (send) and the
return signal will be connected to the mixer through the “ring” (return) of the jack.
The Subgroup unit includes two outputs(6.). Please note that these are designed to
send balanced signals, using space-saving stereo phone plugs. The tip connects
as usual to the hot signal (+), the ring to the cold signal (-) and the sleeve to the
ground.
We have already seen their use in connecting additional Subgroups to a Stereo In
or Multiple unit.
These outputs are also active in the back to L/R mode and can therefore be used
as a second independent Subgroup output. Not depressing the back to L/R button
lets the Subgroup act as a simple master L/R, creating a “second mixer within the
mixer”.
Another interesting application for these outputs is as a balanced insert: Connect
a stereo equalizer to them for example, then connect its outputs to a Stereo In or
Multiple unit. This lets you profit from the effect unit’s balanced inputs and outputs.
This application could be useful with any Subgroup unit, routing it from its outputs,
via cable, to one of the aforementioned Stereo In or Multiple units (simply by not
depressing and therefore not activating the L/R to BUS / back to L/R button).
