The CircuitWerkes AC-12 rack-mounted coupler bay is ideal for replacing that wall full of individual telephone couplers. You can fit up to 12 full-featured autocouplers in a 3RU (5-1/4") rack space. When you install the AC-12, you can eliminate the problems and mess of multiple coupler boxes and wires that you used to need for serious telephone distribution and production. The AC-12's card frame features a two-channel audio buss that can be accessed with the flick of a switch from any of the individual couplers. If you want to take a separate program feed from an individual coupler, the audio select switch allows you instant access to the coupler card's independent audio port without affecting buss audio. As you might have guessed, sending audio to the couplers is easy. All you have to do is connect your source to one of the AC-12's two, bridging, buss inputs, set the coupler switch to the buss you want, adjust the level (a one-time adjustment) and you're ready to send. If you ever need to feed a second program down some of your lines, you'll wonder how you ever lived without the second audio buss. Not only can you send two feeds simultaneously, you can also leave a second source permanently wired to the coupler. There's no need to build an external switcher for your second audio feed.

At the heart of the AC-12 is the AC-1 autocoupler card. Now available in two versions, both offer a host of features not found on any other coupler. The AC-1s can do it all. Both local and remote manual controls let you operate the coupler from anywhere. The AC-1's status indicators for ring, online, power and clipping are visible through the smoked front cover, making it easy to tell the status of each card. Remote outputs for ring and online are also available on the back of each card. A user selectable, momentary or latching, dry relay contact closure occurs whenever the coupler comes on-line. The AC-1 offers a ring counter feature that let's you select on which ring each coupler will answer.

The newest addition to the AC-1 family is the AC-1h. Featuring a simple active hybrid, the AC-1h provides an active, balanced, audio output and a bridging, balanced, audio input that is ideal for IFB feeds from intercom systems and any other system that needs a bridging feed. Depluggable screw terminals give you easy access to the local audio input and outputs. An active audio limiter gently prevents telephone line overload while maintaining optimum "send" levels so callers will have no trouble picking up audio from your couplers. The AC-1h includes gain controls for both local send and receive levels. Designed from scratch in 2008, the AC-1h is microprocessor controlled and adds even more features beyond the original AC-1 coupler series.

If you currently have a bunch of couplers stuck on a wall or a rack shelf, you'll appreciate the space-saving benefits of the AC-12. You may be shocked to realize just how much space you can save with the AC-12.
