Overview Introducing the Universal Host Universal Host will allow you to send and receive audio through your multi-line PBX, ISDN, VoIP or analog telephone. 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. The 16 bit USB audio CODEC allows stereo recording at up to 48 kHz sampling rate, with the talent voice on the left channel in full bandwidth, and the caller on the right.

Connect your telephone handset to the RJ-22 jack on the back of the Universal Host marked . If you are only using one mic, please continue to Step 3.
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.
Configuration A-B-C Selector Switch Use this switch to select the correct type of handset microphone your telephone uses. A=Electret, B=Carbon, C=Dynamic. Your Universal Host will only function correctly if the handset type selector switch is in the correct position. This switch changes signal level, impedance, and wiring to accommodate the differences in handset microphone types.
Operation Placing a Call with Universal Host Use your telephone to place or screen a call. When you are ready to take the call on Universal Host, simply press the button. Universal Host will disable the microphone in the telephone handset when the button is pressed. Make sure you do not put the telephone handset back in it’s cradle while you are on a call. This will still drop the call.
FAQs 1. Will Universal Host work with my ___ PBX phone system? The three handset microphone types that we support, electret, dynamic and carbon, cover every handset microphone type that we have seen in use, but the wiring in each phone can change without notice. Universal Host works with virtually any PBX, ISDN, VoIP or even a plain old analog telephone as long as the telephone has a standard handset. 2.
FAQs 8. Why does my laptop / tablet not receive audio from the Universal Host for recording? Many newer laptops / tablets only have a TRRS headset jack. If you want to record 2 track stereo audio, you will need to either get a sound card with a stereo line level input for your laptop or use a USB or FireWire interface product. 9. How do I record onto my computer and edit the files? You will need to purchase or download any audio editing software of your choice.
