Introduction to Home Theater Introduction to Home Theater Surround Modes there are different theories as to the best way to present surround sound and to this introductory section will help you to familiarize yourself with some basic concepts distribute each audio channel’s sounds to the surround-sound system’s speakers. unique to multichannel surround-sound receivers, which will make it easier for you to set A variety of algorithms have been developed in an effort to recreate the way we hear up and operate your Avr.
Place Your Speakers Place Your Speakers NOTE: In a 7.1-channel system, you must choose to use either surround back speakers or front height speakers – you cannot use both simultaneously. determine the locations for your system’s speakers according to their manufacturer’s Placing the Left, Center and Right Speakers directions and the layout of your listening room.
See System Settings, on page 39, for more A. Tighten Cap B. Insert Banana Connector information. (the Avr 3700 and Avr 370 have two hdmI output connections.) into Hole in Cap the hdmI connector is shaped for easy plug-in (see illustration, below), and hdmI cable runs are limited to about 10 feet (3m).
Types of Home Theater System Connections Digital Audio Connections – Coaxial Video Connections coaxial digital audio jacks are usually color-coded in orange. Although they look like many source devices output both audio and video signals (e.g., blu-ray disc, dvd standard rcA-type analog jacks, you should not connect coaxial digital audio outputs to player, cable television box, hdtv tuner, satellite box, vcr, dvr).
Types of Home Theater System Connections Radio Connections RS-232 Connector your Avr uses separate terminals for the included fm and Am antennas. the fm antenna your Avr’s rS-232 serial port may be connected to an external control system to allow uses a 75-ohm f-connector.
Avr’s Subwoofer connector to your subwoofer as explained in Subwoofer Connections, on page 14. note: the Avr 3700 and Avr 370 CAUTION: Before making any connections to the audio/video receiver, ensure provide connections for two subwoofers.

Making Connections Connect Your HDMI Devices Connect Your Composite Video Devices If any of your source devices have hdmI connectors, using them will provide the best use composite video connectors for video source devices that don’t have hdmI or possible video and audio performance quality. Since the hdmI cable carries both digital component video connectors.
Making Connections Connect Your Analog Audio Devices Connect Your Video Recorder use the Avr’s analog audio connectors for source devices that don’t have hdmI or digital connect an analog video recorder’s video input connector to the Avr’s composite monitor audio connectors. NOTE: If you’re installing a multizone system, make analog audio out connector.
