STAC is a telephone talk management system that puts you in control of your talk shows, call-ins and phoners with great sound, ease of operation and scalable configuration.
STAC incorporates a pair of Comrex high-performance digital hybrids with automatic audio level control. The result is the most natural sounding telephone audio, even when conferencing multiple callers. A compact, rack-mounting mainframe houses the hybrids, the multiline controller and all telephone and audio connections.
Call screening and control are available from any networked computer, using a standard web browser, with the included STAC IP. With STAC IP, your talent can host their shows from anywhere there is an Internet connection or you can economically create more control points from any computer on your local network.
The STAC interface features a clean, logical design, which allows functions to be mastered quickly. Dedicated buttons, with associated multicolor LEDs, minimize the number of button presses and make it easy to determine status of phone lines and callers.
Features
- Dual, high performance digital hybrids
- Configurations for six and 12 phone lines
- Selectable caller ducking
- Ethernet port allows control of all call functions via STAC IP
- User-friendly interface
High-Performance Hybrids
STAC incorporates a pair of Comrex high-performance digital hybrids with automatic audio level control. The result is the most natural sounding telephone audio, even when conferencing multiple callers. A compact, rack-mounting mainframe houses the hybrids, the multiline controller and all telephone and audio connections. Each hybrid has an individual audio output to send to your audio mixing console or router.
STAC IP
Call screening and control are available from any networked computer, using a standard web browser, with the included STAC IP. With STAC IP, your talent can host their shows from anywhere there is an Internet connection or you can economically create more control points from any computer on your local network.
Easy-To-Use Interface
The STAC interface features a clean, logical design, which allows functions to be mastered quickly. Dedicated buttons, with associated multicolor LEDs, minimize the number of button presses and make it easy to determine status of phone lines and callers.
Production Tools
An additional audio output sums the two callers with the host audio – great for connection to a recording device. Flipping a switch on the back of a control surface is all that is required to select Studio/Producer or Screener Mode.
Auto Attendant
STAC is equipped with Auto Attendant, which automatically answers incoming calls with your custom outgoing message. Call is answered after two or six rings, the message is played and, at the end of the message, the line is put on hold. If no message is recorded, lines will automatically be answered and put on hold. Function selected from control surface.
VIP Mode
Two phone lines can be assigned to VIP mode, removing them from the priority rotation and Auto Attendant. These can be reserved for placing outgoing calls and incoming hot lines.
Simple Configuration
After initial installation, no additional configuration is required for mainframe. Set-up controls are behind an easy-access panel and include pots for level adjustments and DIP switches for configuring Auto Attendant, auto-disconnect, automatic audio gain control, VIP and other settings.
