AVR

Types of Home Theater System Connections

Radio Connections

Your AVR uses separate terminals for the included FM and AM antennas. The FM antenna uses a 75-ohm F-connector.

The AM antenna connector uses spring-clip terminals. After assembling the antenna as shown below, press the levers to open the connectors, insert the bare wires into the openings, and release the levers to secure the wires. The antenna wires are not polarized, so you can insert either wire into either connector.

RS-232 Connector

Your AVR’s RS-232 serial port may be connected to an external control system to allow it to transmit control commands to the AVR. The port is bidirectional so that the AVR can transmit status updates to the control device. Connecting and using the RS-232 port requires considerable technical knowledge and is best left to a professional custom installer.

Network Connector

The AVR’s Network connector allows you to enjoy Internet radio or content from other DLNA-compatible devices that are connected to the same network. Use a Cat. 5 or Cat. 5E Ethernet cable to connect the AVR’s RJ-45 connector to your home network.

USB Port

The AVR can play audio files from an Apple iOS® device connected to the USB port, and allows you to control the iOS device via the AVR remote control. The AVR can also play MP3 and WMA audio files from a USB device inserted into the USB port. Insert the connector or device into the USB port oriented so it fits all the way into the port. You may insert or remove the connector or device at any time – there is no installation or ejection procedure.

The USB port on your AVR is also used to perform firmware upgrades. If an upgrade for the AVR’s operating system is released in the future, you will be able to download it to the AVR using this port. Complete instructions will be provided at that time.

IMPORTANT: Do not connect a PC or other USB host/controller to the AVR’s USB port, or you may damage both the AVR and the other device.
