5. Input Connections
Choosing the Correct Modules
Select the combination of Mic and Line inputs to suit the application. All of the input ports are the same, so arrange
the inputs according to the logic the operator will use at the site. Most of the time, Standard Mic Modules and
Standard AUX Modules will be the proper, economical choice.
Reminder: Remove Jumper on any "M" module when used with dynamic or battery-powered condenser mics. This
defeats the module's built-in phantom power, reducing the possibility of noises from faulty cables or connectors.
Specific Module Applications
There may be specific situations which call for a special input module. There may be applications where
Compression or Remote Volume would be useful.
When a 600 ohm balanced line input is required, use a line matching input module.
When a 10k ohm bridging input is required, a bridging input module should be used.
If a signal must be split between the AX-1000A and an input elsewhere, employ an aux input/line output
module.
Make sure the AC power is off before inserting or
removing modules. Plug each module into its input port
by sliding it between the guide rails. Secure each
module with two screws. Cover unused ports with
blank panels.
6. AX-1000A Configuration : Quick Setup
The AX-1000A has been designed for quick, efficient configuration, installation, and operation. In most situations,
just fill the ports with Standard Mic Modules. When the specified mics are not phantom-powered, remove a Jumper
on the Standard Mic Module before inserting it into the port.
If a high-impedance mic is used in the system, use a High Z mic module.
If a line input is specified, use the Standard Aux Module.
Do not change the setting of the NOM Attenuation Control from its factory-set 10 log NOM position. Do not change
the Off-Attenuation Control on each channel from its factory preset.
Master Volume Control
The Master Volume Control allows sensitive adjustments to the overall system output. Ordinarily, after the Master
Volume Control is set, system gain is held constant by the automatic mixing circuitry. However, in complex
combinable systems with many inputs it may be necessary to boost or attenuate the overall gain as different
rooms are combined.
