INPUT & LINK -
Both connectors at the top and the bottom of the AX12C can operate as input or link, to
connect an appropriated processed amplifier or to link the column to a second one.
The AX12C does not include an internal passive crossover for filtering the signal, but only an internal
protection that excludes the internal speaker to protect them from excessive input power. The protection
should not trip with a typical music program, but only with a massive and constant power signal, like a
feedback. The connections are the following:
INPUT - LINK
NL4 pin number
internal connection
1+
+ speakers (pass thru link speakon)
1-
- speakers (pass thru link speakon)
2+
+ no connection (pass thru link speakon)
2-
- no connection (pass thru link speakon)
WARNING: the maximum quantity of AX12C that can be linked together depends by the load capacity of the appropriate processed
amplifier. When powered from the SW2100A subwoofer or from the QC2.4 suggested amplifier, a maximum of four AX12C can be
connected to each power output.
TOOLS
This is a list of tools that can be useful to set properly a vertical column array system.
CABLE TESTER
It is a good practice to check all cables before each installation, because even one faulty cable can compromise heavily the system performance.
INCLINOMETER WITH LEVER
This tool can be used to verify the vertical array angle. It can be used at the top or at the bottom of the array In this case you have to sum all splay
angles, so the maximum precision is needed for aiming the vertical array, particularly for long throw applications.
LASER DISTANCE METER
This instrument can be useful to measure the height of the vertical array and to know the distance between FOH-Subs and FOH-Array for setting
the delay time.
ACOUSTIC MEASUREMENT SYSTEM
(SMAART, SATlive or similar)
These are useful to measure delays, phase and response of the system.
