8. Operation: Setup Checklist
Insert the modules. Connect the output of the AX-1000A to the system power amplifier input. Connect the input
sources according to the following checklist. For more specific instructions, see Sections 9~12. Look in the
Appendix for a checklist which can be copied for use at the job site.
1. Insert each Mic input module.
(1) Choose Mic to use.
(2) Defeat phantom power if appropriate.
(3) Insert module.
(4) Connect input source.
(5) Repeat on each input.
2. Adjust Mic Module.
(1) Power-up mixer, raise Master Volume and one channel's Input Volume.
(2) Adjust module gain, low-cut filter and any other functions on module.
(3) Turn Input Volume off.
(4) Repeat on each input.
3. Set up Maximum Gain on Mic Channel(s).
(1) Set Channel Volumes and Master Volume 'off'.
(2) Confirm that NOM Attenuation is in the center detent.
(3) Confirm that all Off-Attenuation Adjustments are fully counter-clockwise (-40 dB).
(4) Adjust the Master Volume to the desired nominal operating level.
Maximum signal to noise is achieved with input volumes set between one o'clock and four o'clock. Set
Master Volume so that as many input volumes as possible can be set at optimum, keeping in mind desired
overall acoustic level.
(5) Adjust input volume to a level just below feedback; log or mark setting.
(6) If a channel gates on due to ambient noise, raise the Threshold (use Gate LEDs as a guide.).
(7) Lower Input Volume to zero.
(8) Repeat on each input.
4. Insert and Set Up Line Input Modules.
(1) Connect input, adjust module gain.
(2) Adjust Input Channel Volume.
(3) Repeat for each line input.
5. Insert and Set Up Special-Function modules.
(1) Connect input, adjust module gain, other function(s).
(2) Adjust Input Channel Volume.
(3) Repeat for each special-function module.
