ZonePro 640/641 Application Guide
Notes - Retail Application
1. The configuration is setup from the Wizard function and is used to select the main inputs
to each zone except the sales floor where the ZCs are selected as the source and level.
2. All paging is done from the phone page interface and can be steered to the sales floor,
the stock room, and the office, but not the music on-hold. Page steering is done from
the front panel of the ZonePro 640.
3. The Zone Controllers are wired with CAT5 cable in series with the ZC-3 (Source Selection)
as ID #1, and ZC-1 (Volume) as ID #2, and are placed next to the cash register.
4. EQ, Feedback Suppression and De-Essing are used on the phone page input to help
improve intelligibility and reduce unwanted feedback in the system.
5. The Bandpass Filters are used to reduce the out of band information being sent to the
speakers so their efficiency can be maximized.
6. EQ is used in all zones to make the system sound as good as possible.
7. Auto Gain Control is being used on all output zones to maintain the signal level.
