Studio Telephone Access Center (STAC) puts you in control of your talkshows, call-ins and phoners with great sound, ease of operation and scalable configuration

What are you talking about?
A call-in on local politics.
An interview with the winning quarterback from his hotel.
An eyewitness with late-breaking news.
A dedication to the one someone loves.
Congratulating caller number six on winning concert tickets.
The telephone has always been essential to live broadcast. 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 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.

The attractive, ergonomic control surfaces offer two operational modes, selectable with a flip of a switch:

Studio/Producer Mode provides both pre-air and on-air caller management.
Screener Mode simplifies the task of screening and queuing callers.
Powerful call management can be quickly mastered with minimal training. A single control surface is included for basic operation. For more demanding programming, up to four control surfaces may be used.

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.

Innovative features include an Auto Attendant that automatically answers incoming callers with your custom message and puts them on hold; dedicated control surface buttons to designate the next caller to be placed on air and to activate an external recorder or delay; and program-on-hold audio.

The STAC12 mainframe and control surface are configured for 12 phone lines, while the STAC6 is configured for six lines. Expanding a STAC6 to a STAC12 in the field is quickly accomplished by installing a mainframe extension card and control surface "sidecars".

No matter what you're talking about, you'll be talking about quality, convenience and value when you put the Comrex STAC on the line.

DH22

The DH22 offers the same functionality as the DH20 but in a dual configuration.

The manual TCB-1A and automatic TCB-2A provide clean, transparent transformer connections from telephone lines to external audio equipment

Comrex Auto-Answer and Manual Telephone Couplers provide clean, transparent transformer connections from telephone lines to external audio equipment. State of the art circuits and rugged construction assure highest quality and years of reliable service. Both couplers feature modular jacks for quick installation by non-technical personnel. Comrex Telephone Couplers are designed and FCC registered specifically for broadcast use. Program may either be sent or received on both the auto-answer or manual models.

The TCB-1 provides a switched hold connection to a telephone line so that the telephone set may be hung up during program feeds. This eliminates the need for special telephone instruments with push-to-talk handsets or exclusion keys. Use with any modular phone to send or receive live or taped material. The TCB-1 does not interfere with normal use of the associated telephone instrument and does not require batteries or external power.

The TCB-2 automatically answers a telephone line on the first ring and disconnects that line when the calling party hangs up. It is ideal for unattended situations such as listen lines, IFB feeds, dial-up network, remote transmitter sites and satellite links. The TCB-2 needs a momentary open or reversal from the central office to disconnect. Most but not all CO's provide this signal. An optional dial tone detect board is available if required. The TCB-2 is powered by an external AC or DC Supply.
