Studio Telephone Access Center (STAC) 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 a 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. No additional computer is needed to serve the STAC IP webpage, as it is served from the mainframe. Your connections are secured by password protection and no dedicated client software needs to be installed. In addition to replicating the call status information on the control surfaces, STAC IP also provides fields for additional information about callers and text "chat" among those on your show network.

Comrex STAC-12-CTRL-SURFACE Key Features:

  • Dual, high performance digital hybrids for reliable,natural sounding caller audio, even when conferencing.
  • Configurations for six and 12 phone lines. Easy toexpand in field.
  • Flipping a switch on the back of a control surface isall that is required to select Studio/Producer or Screener Mode.
  • A standard web browser can be used on any locallynetworked or Internet connected computer for call screening and control.
  • Auto Attendant for automatically answering incomingcalls with your custom outgoing message. Call is answered after two or sixrings, the message is played and, at the end of the message, the line is puton hold. If no message is recorded, lines will automatically be answered andput on hold. Function selected from control surface.
  • Two phone lines can be assigned to VIP mode, removingthem from the priority rotation and Auto Attendant. These can be reserved forplacing outgoing calls and incoming hot lines.
  • Selectable auto-disconnect of calls terminated bycaller.
  • Selectable automatic gain control for consistentlevels on-air and send audio down the line to your callers. A separatelycontrollable caller level boost may also be used.
  • Talent maintains control using selectable caller ducking that lowerscaller audio level when talent speaks.

Comrex STAC-12-CTRL-SURFACE Mainframe Features:

  • No configuration required after initial installation.Set-up controls are behind an easy-access panel and include pots for leveladjustments and DIP switches for configuring Auto Attendant, auto-disconnect,automatic audio gain control, VIP and other settings.
  • Front panel features three bicolor LEDs indicatinglevel status of audio input and hybrid levels.
  • Telephone line connections provide loop-thru to othersystems or telephone sets sensing loop-thru provided for PBX interconnection.
  • Callers are conferenced within the STAC mainframerequiring only one mix-minus audio input to feed both hybrids.
  • A separate audio input is used for program-on-hold.
  • Each hybrid has an individual audio output to send toyour audio mixing console or router.
  • A third audio output sums the two callers with thehost audio - great for connection to a recording device.
  • Ethernet port allows the integrated web server to deliver call screeninginfo and to control all call functions via STAC IP.
