6.0 E4 System Setup

Page setup with Opti-voice®off

1.Set Opti-voiceto Off in the Page Setup control panel. This enables the Ducking Depth and Release Time controls.

2.Set the Ducking Depth to the amount in dB that the music will be reduced to once a page is triggered.

3.Set the Release Time to the length of time (secs.) it will take for the music to return to its original level. The Release Time can determine the overall quality of a page.

If you pause frequently while paging or release the push- to-talk (PTT) button during a page, use a long Release Time.

If the Release Time is too short, the music will quickly return and the level will be reduced once the page continues.

Page setup controls

Paging Type – Identifies whether you are using fixed-zone or multi-zone paging.

Fixed-zone– Enables paging in all zones that have the PAGE source assigned to them.

Multi-zone– Enables paging in all zones that have the PAGE source assigned to them and allows the user to select each zone independently using a Multi-zone Paging user interface. See “Source assign” on page 49, “Setting up Multi-zone pag- ing” on page 51, and “Multi-zone paging user interface opera- tion” on page 61.

Page control – Selects which page keypad is used for paging. Active only when Paging Type is set to Multi-zone.

Detection type – Determines the page trigger method:

Auto – Automatically senses input signal level. Requires that the Page Threshold level be set.

PTT – Detects contact closure from push-to-talk (PTT) micro- phones. This disables the Page Threshold slider control.

Opti-voice selection – The Bose® proprietary Opti-voice paging system provides the appropriate sound level regardless of varia- tions in speech projection. When on, this feature implements pre- determined settings for Ducking Depth and Release Time, and source EQ.

Programmer’s Note: When the Opti-voice paging sys- tem is on, the Ducking, Source Leveling, and Input EQ controls are unavailable. Only when the Opti-voice paging system is off can these values be changed individually.

Page Threshold slider – The Page Threshold slider setting determines the signal level required to trigger a page when Auto Detection is used.

Page Active indicator – The Page Active indicator will be green when a page is being sent.

Ducking parameters – There are three settings for ducking:

Depth – Determines how much to reduce the level of program material when a page starts.

Release Time – Determines the amount of time to keep pro- gram material reduced after a page ends.

Hold Time – Determines the amount of time that the page remains active after the page signal has stopped. Page length and Hold Time determine the point at which the Release Time starts. See “Paging operation” on page 52.

Setting up Multi-zone paging
