Providing an echo-free interface between an analog and digital system — both of which are wideband and high fidelity — is no simple feat. Yet Clear-Com has just done that, designing the HLI-2W2 Interface Module with superb audio clarity, simplicity and durability in mind. The system is capable of interfacing with up to two channels of 2-wire intercoms, in two primary analog partyline formats: Clear-Com and RTS.
