JobSite Systems A30-X12 Configuring Your System, Tools Required, Complete configuration worksheet

Configuring Your System

Because the A30-X12 offers so many configuration possibilities it is important to plan carefully before you install it. Draw a block diagram of your system and use the Configuration Worksheet on page 7 to record how you plan to connect your

A30-X12. Here is an example filled out according to the block diagram on page 7. Mark the cables with Wire labels, describing where the cables originate from, rather than where they will terminate.

Tools Required:

■1/8" Slotted screwdriver

■Wire stripper

■Wire labels

INSTALLATION

Complete configuration worksheet

1.Select an appropriate location for the A30-X12

2.Run all the necessary wiring to the A30- X12. Label the wires for future reference.

3.Strip 1/4" of insulation from the end of each speaker wire. Tightly twist the end of each wire until no frayed ends remain.

4.Unscrew the Red and Black speaker wire connectors.

5.Insert each wire into the predetermined Speaker Outputs, using the configuration worksheet as the guide. Tighten the connector until the wire is securely clamped.

6.Connect the Pre-Amplifier or Receiver to the predetermined Channel Inputs, using the configuration worksheet as the guide.

7.Set the BusMatrix input switch setting for each channel.

8.Set the position of the Turn On Mode switch. Connect 12 Volt source if applicable.

9.Connect the AC power cord to the A30- X12, and then plug it into an “Un- switched” AC outlet.

10.Turn the Master Power switch on. The switch is located on the front panel of amplifier.

Control Output

This terminal provides a 12-Volt DC signal suitable for triggering automated switchers, motorized screens, some electric curtain controls, etc. The trigger voltage is present only when the amplifier is active or "on". When the amplifier turns "off", the 12Volt signal is off.

Cascade Audio Outputs

The "Cascade Audio Outputs" enable you to connect another amplifier to your preamplifier output. The connectors are gold-plated RCA phono jacks. Connect them to another amplifier’s inputs with a standard audio patch cable. The outputs are not buffered; if you wish to daisy chain more than 3 JobSite amplifiers you will need a buffered distribution amplifier.

Level Adjustment Knobs

The rear panel level adjustment knobs allow you to adjust the maximum output level of any channel individually.
