innkeeper PBX Desktop Digital Hybrid User Guide JK Audio
Introduction Innkeeper PBX will allow you to send and receive audio through your multi-line PBX, ISDN 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. What is a Digital Hybrid? The innkeeper PBX digital hybrid connects audio signals to and from the handset side of a telephone without the variations in quality found with analog hybrids.

Connection (continued) To connect innkeeper PBX through a mixer—Mix Minus Setup Connect Aux (or FX) Send on mixer to Send 1 on innkeeper PBX, Mic/Line button out (Line) Connect Caller to any line level input on mixer Number of microphones depends on mixer Use Main Outputs, USB or Firewire connectors to send audio to recording device or broadcasting equipment inputs For whichever input channel you have the Caller connected to, turn the corresponding Aux control to minimum (usually hard left).
Operation • Using balanced XLR cables (not included) with 1/4” TRS adapt- ers if necessary for your mixer, make all connections as shown. • On your mixer and on innkeeper PBX, set all controls to nominal levels, usually 12:00. • On your mixer, set local microphone channel input gain for good microphone level. • On your mixer, set all output faders and the main mix control for good recording level of the local audio. • On your mixer, set the headphone level for comfortable listening.
Operation (continued) Telephone Handset Innkeeper PBX will disable the microphone in the telephone handset when you press the Broadcast button. Use your telephone to place or screen a call. When you are ready to take the call on innkeeper PBX, simply press the Broadcast button. Innkeeper PBX will automatically release the Hold (if Hold is used). 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.
Operation (continued) Send Signal Level The Send LEDs display the signal level as it goes out to the phone line. The goal is to drive the phone line at high enough levels to avoid phone line noise, but not so loud as to cause excessive clipping. Adjust the Send level control so that you rarely see flashes of the red -3dB peak Send LED. These flashes should occur only during loud speech bursts.
FAQs ? ! Will innkeeper PBX work with my ___ PBX phone system? Probably yes. We have to say probably because the handset interface is proprietary and therefore can change from model to model. We have no way of predicting how a phone manufacturer will use the handset wires in the future. 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 wire diagrams can change without notice.
FAQs ? Why does my laptop only record half of the conversation? I ! am using the Stereo output on the innkeeper PBX and I have a stereo cable. Most laptop computers only have a mic input, which is mono. 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. ? ! 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.
