This is a user manual that describes the operation of the iPlus Variable Attenuator and Interface Box, including audio output cable wiring, interface box control buttons, quick start tutorial, configuration for 5 radios, etc.
The W2IHY iPlus is a device designed to route rack audio to more than one radio simultaneously without the need for plugging and unplugging cables. It features extensive RFI and ground loop protection built into its rugged steel chassis. The unit allows users to connect up to three radios, an amplifier, and a speaker system via simple front-panel switches.
This three-position rotary switch directs audio and PTT from a single source to one of three five-pin DIN outputs.
The device is designed to send rack audio to more than just one radio, specifically supporting up to three radios.
This switch reverses the phase of the audio output by 180 degrees for proper AM modulation asymmetry.
