The MultiPhones II system from Henry Engineering provides reliable listening facilities for DJs and studio guests, each with their own headphone amplifier, volume control, and jacks. The master unit supports zoned talkback, allowing you divide the listeners into three groups for "host/guest" setups and more.

The master unit has three outputs, which can support up to 12 guest pods, connected by standard CAT5 cables. With inputs for program audio and talkback audio, the master unit also has master level trimmers for pre-setting maximum user levels. The talkback system overrides normal program audio and allows a producer or engineer to speak to guest pod listeners. Three talkback buttons on the front of the master unit allow you to select which zone or zones to address.

The system is optimized for high-efficiency headphones, but any combination of different headphones can be used since each guest pod has its own headphone amp. The unit has a built-in power supply and can be rack, wall, or cabinet mounted.
