Setting Audio Input Levels

The system has two inputs for paging or music. Either input may be

connected to any or all zones via software or front panel interface. If

no paging and/or music from these inputs are desired in a particular

zone, set the audio volume level of that zone to mute.

Note that Input B is the preferred music input due to its ability to be

shut down via a contact closure.

The audio input levels are set in a similar way as the masking. Use the

arrows on the front panel to move left and right to nd the input A

and input B eld for each zone. The inputs are enabled and level set

for each zone for exibility. Arrow to each zone for each input and set

the level using the up and down arrows.

Lock/Unlock the Front Panel

The settings of the Qt 600/Qt 300 can be locked by a physical switch

on the back of the control module. Lock the control module panel by

moving the “lock” switch to the “Locked” position. This prevents any

casual interaction from changing the settings.

Unlock the Front Panel and Control the System

1. Loosen screws and lift the control module slightly and hinge it

forward to give access to its connection panel.

2. Move the panel lock switch to the UNLOCKED position. Close

the module.

3. Press NEXT or PREVIOUS to scroll between screens for adjusting

sound masking, paging or music volumes by zone.

4. Modify a value by 1 dB on any screen by pressing + or -.

5. Press NEXT to accept a screen value.

6. After completing adjustments, lock the system.

NOTE: The system returns to the Version, Status screen after ve

minutes of inactivity. Z1 indicates Zone 1, Z2 indicates Zone 2, etc.

If an error is detected, an error code is displayed on the control

module. See page 35 for details about Error Codes.

This gure shows the format of the panel for conguring the volume for input A or

B. The level of the input is set for each zone, where the example shows Input A is

level 6 for zone 1.
