EJ-Controller

Technical Information

This Controller is designed to be used with the EJ-22 speaker. This control box distributes audio and power to each of the speakers in a ring network configuration.  It has low level audio inputs to connect to your audio source.  Included in the system is a DSP for audio processing.  A Raspberry Pi computer is utilized to provide Ethernet, Wi-Fi, and

Bluetooth communication.  USB ports are also available as well as HDMI and aux audio out.

The EJ-22 Controller plugs directly into the wall with an IEC cable.  Audio is connected through a 3 pin terminal block. Speakers are connected to the controller with Ethernet cable in a serial chain configuration.  The last speaker is connected back to the controller.  This configuration allows the controller to check the continuity of the connections.

Communication to the controller is possible utilizing the built in features of the on board Raspberry Pi computer.  Many custom configurations are possible utilizing the power and flexibility of this platform.
