JK Audio Innkeeper PBX Digital Hybrid Broadcast Phone Handset Audio Interface

Near Mint Cosmetic Condition • Tested/Guaranteed • 115V/230V Power • Connects Between Phone and Handset for Bi-directional Broadcast Audio Very lightly used and in close to mint cosmetic condition.  It includes the accessories as shown. This hybrid connects between the Telephone and the Handset, and not between the phone and the wall jack. That way it doesn't matter whether the phone is analog, digital, VoIP or whatever. The power supply accepts both 115V and 230V AC. Note that JK Hybrids in my experience operate best with a low level of input signal, so start testing by turning down the Send gain control to the point where just the first LED level indicator is peaking lit.
