Example: Zone 1 is planned to be masking level 9. Auto Ramping

is set to -15dB. On day one, the level is active 15dB less than the

planned level. Day 2, it is only 14 dB lower. It rises each day until it is

functioning at full masking.

Changing Input A and B Level

The control module operates as a paging amplier. Refer to the con-

trol module’s specications for the electrical characteristics of Inputs

A and B. Each signal is routed to all zones. The (acoustical) output

level for each signal can be specify for each zone. Set a Zone/ Input

A/B output level to “Mute” if you do not wish to connect the signal

to the zone.

NOTE: 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. With-

in the Operations window, each zone has a selector for the level of

input A or B.

1. Select the modify button.

2. Select the zones to modify on the right by clicking the box.

3. Change the value in the left window.

4. Select Submit.

Auxiliary Line Level Adjustment

From the operations tab and the zone block (shown in gure 13), se-

lecting the Input A or Input B link in the window will open the window

shown below. This allows the incoming level on the auxiliary input

to be left at line level or increased by 10 dB in the case that the line

level is below typical AV line level -10 dBv to +4 dBv.
