Overview Introducing the Broadcast Host™ Broadcast Host will allow you to send and receive audio over analog telephone lines. While this may seem like a simple task that any telephone can do, the challenge is getting the best quality audio from such a limited audio path. What is a Digital Hybrid? The Broadcast Host digital hybrid connects audio signals to a standard analog telephone line without the variations in quality found with analog hybrids.

Getting Connected Note: There are 2 ways to set up the audio equipment for Broadast Host. Connecting to a Single Line Phone 1. Connect the supplied RJ-11 phone line cable between the jack marked and your wall jack. Be sure this jack supports standard single line analog telephone operation. 2. You may want to connect an auxiliary telephone to the Broadcast Host jack so you can dial out and set up calls, or use the feature to answer incoming calls.
Getting Connected 9. If your mixer doesn’t have a mix-minus bus: Whichever input channel you have the connected to, turn the corresponding Aux control to minimum. All Aux controls for other channels should be set for audio sent to the phone line. Each Aux Send bus is completely separate from all other outputs, so these Aux controls will not affect what is heard on the Main outputs or on any other Aux buses.
Operation Auxiliary Telephone An auxiliary telephone provides you with an easy way to dial out or set up your calls. Broadcast Host will disconnect the auxiliary telephone when you press the button. If you need to take the call back on the aux telephone, simply pick up the telephone handset before the Broadcast Host’s button is pressed. To use an auxiliary phone equipped with a “Hold” feature to place or screen a call, first set up the call and place the call on hold.
Remote Control Remote Control Jack The RJ-45 jack on the back of the Broadcast Host provides connection to an optional JK Audio Guest Module 1 remote control, or it can be wired to the switch contacts on your broadcast console. Do not connect this jack to the network port on your computer. RJ-45 Pinout: 1: Ground 2: Call / Drop Control (main control pin) 3: Ring / OH LED 4: DTMF Input 5: +4.
FAQs 1. Will the digital hybrid provide phantom power for a condenser mic? No, this device will not provide phantom power. If you connect a microphone directly to the Broadcast Host, you should use a dynamic mic. 2. What happens if someone takes a second phone off-hook when the Broadcast Host is on a call? Broadcast Host will treat the other local voice the same as the caller.
FAQs 7. There is a loud hum on the output of my Broadcast Host, even when nothing else is connected. What else could it be? Make certain you are using the regulated power supply that was shipped with this unit. Power supplies are not all the same. 8. I need to be able to use my Broadcast Host at an office building but they only have a multi-line PBX phone system. Is there some way I can still connect this device? Talk to their phone specialist and ask for a standard analog line.
