Each Guest Pod contains a stereo headphone amplifier, volume control and headphone jacks. Both 1/4" and 1/8" (3.5mm) jack are provided. A pair of (parallel) RJ45 jacks on each Guest Pod permit multiple units to be "daisy chain" connected to each Master unit output. As a convenience, each Guest Pod has a "cough button" and "mic-on" LED that can be wired to the user's audio console or other equipment, although these functions are not part of the MultiPhones II system per se.
The MultiPhones II system is optimized for use with contemporary high-efficiency headphones with impedances between 24 and 600 ohms. Because each Guest Pod contains its own amplifier, any combination of different headphones can be used. There is no interaction between units, and no degradation of audio performance regardless of the number of Guest Pods used. The system uses low-Z balanced audio distribution so that long cable runs do not affect audio quality.
