weight frame structure and remarkable affordability.
Aztec is available in three frame sizes providing 32, 40,
48 and 52 mono inputs, 2 additional stereo line inputs
and a stereo ambience mic input. Console and extender
linking is provided as standard.
The extensive feature set is the result of long experience
combined with the feedback of many respected sound
reinforcement professionals.

each of the Main output faders.
•12 VCA Sub Groups with VCA Solo.
•8 Audio Sub Group outputs with balanced inserts.
•8 Mono and 2 Stereo Auxiliary outputs with balanced
inserts.
•12 x 8 Matrix with balanced inserts.
•4 band EQ with parametric mids, sweep HF and LF
with switched Bell/Shelf curves plus Sweep Hi-Pass
filter.
•Optional full stereo input modules.
•All inputs and outputs fully balanced ( including
+4dBu Inserts ).
•Mute and VCA assignment automation as standard.
•Midi message output for control of outboard equip
ment.
•Dedicated recorder interfaces for seamless
performance archiving and post-production.
•Extensive peak reading LED metering.
•Flexible monitor outputs for headphones and
engineers wedge.

FOH and MonitorsFOH and Monitors
Aztec is configured primarily as a FOH console.
In this default mode the master levels for the 8 mono
Auxiliary sends are set on rotary controls. The two
Stereo Auxiliaries (which would normally be used
for any IEM feeds) along with
the 8 audio Sub-Groups, have
100mm faders for their
master levels
However, when more monitor
sends are required the Master
level controls for each of the
Sub-Group and Auxiliary
outputs may be swapped by
depressing the GRP/AUX
swap buttons on each Sub-
Group output module. The
function of the rotary control
and fader are shown by the
LED adjacent to each. The
Solo and Mute functions
swap with the level control
but output connections are
unaffected.

RecordingRecording
Recognising the increasing requirement to record per-
formances, Aztec is unique amongst large format Live
performance consoles in providing dedicated record and
remix functions.

The provision of the fully
balanced D-IN ‘remix’ input,
again on D-Sub connectors
in groups of 8, allows Aztec
to be used for post-produc-
tion of recorded perform-
ances preserving EQ and FX
configurations used in the
original show.
Audio Sub-Group outputs
are available on a D-sub
connector as well as XLRs, for rapid
recorder connection if required.
Using LCRUsing LCR
A fully balanced, level
variable direct record out is
available on jack and, in
groups of 8 channels, on D-
sub connectors wired in
accordance with Tascam
DA98 format. This allows
simple connection to one or
more 8 track recorders.
RecordingRecording (continued)
The Aztec LCR MAIN output bus routing system uses
two controls - a Left/Right pan control and a Blend
control. This allows a centre cluster to be used to ‘an-
chor’ a lead vocalist while still feeding the main Left/
Right stacks to ensure adequate coverage.
The pan operates in the normal way with a constant-
power law. The Blend control adjusts the proportion of
the signal sent to the Left/Right buses and the Centre
bus.

With Blend in the fully counter-clockwise position rout-
ing (and panning) is conventional Left and Right with no
signal sent to the Centre bus.
With Blend set in
the fully clock-
wise position
only the Centre
bus is fed.
With Blend at 12
o’clock all three
buses are active.

MutesMutes
All Mutes on the Aztec control surface with the excep-
tion of those for the three Main outputs are under
central control. They can therefore be operated either by
the Scene Automation system or locally by depressing
the relevant physical Mute button. Local operation
always has priority. Mutes operate (or release) on the
button down-press. To isolate the Mute from central
control depress the channel SAFE key
SolosSolos
Aztec is equipped with a multi-function Solo System.
Three main modes are provided, PFL, AFL and
Solo-in-place. These modes are set from the Master
Module. Default mode is PFL, AFL is
selected by depressing the AFL button.
VCA Solos are also provided and these
are explained in the ‘VCA Masters’
section. Solo-in-place mode can only
be invoked by pressing and holding the
large illuminated SIP button down for
>3 seconds. In this mode all channels
other than the one Solo’d and those
with Safe selected will be muted.
Solo button behaviour is dependant on
press duration. A short press provides
the usual latch-on, latch-off action.
Depressing a Solo for > 2 seconds
provides momentary operation - the Solo clears on
button release.
