INSTALLATION & OWNERS' MANUAL In-Ceiling / In-Wall Loudspeakers DC265 / DC365.
2 DC265 / DC365 INSTALLATION Sound Coverage and Speaker Placement Dual architectural speakers are designed to work within nearly all interior decorating schemes where in-wall or flush mounting is feasible.
3 DC265 / DC365 COVERAGE & SPEAKER PLACEMENT Audio Imaging: Ceiling or wall speakers can be used as pairs for stereo or used in multiples for 5.1 to 7.1 multi-channel applications. Ideally you should place the stereo or front left and right speakers as directionally balanced as possible to the primary listening area.
4 DC265 / DC365 COVERAGE & SPEAKER PLACEMENT When possible, try to reduce the distance of your speaker from the audio source to achieve the best audio results. The optimum wire run should be no longer than 30 feet for the most favorable results. If you must run wire longer than 30 feet, we recommend using larger wire of 12 or 14 gauge.
5 DC265 / DC365 INSTALLATION Caution: Do not attempt to connect the speakers to any source, amplifier or receiver that is turned on. Be sure the receiver is off prior to connecting the speakers. Adhere to all electrical and building code requirements for your area.
DC265 / DC365 INSTALLATION 6 Parallel or series wiring is not recommended for these speakers. The speakers should only be connected to receivers with 4-8 ohm amplifier loading. Avoid parallel or series wiring your Dual speakers with any other speaker type or brand.
7 DC265 / DC365 INSTALLATION When ceiling mounting your speakers, attempt to make the locations as symmetrical as possible. When wall mounting, carefully measure the distance from the floor to the speaker center so both speakers are the same distance from the floor.
DC265 / DC365 INSTALLATION Installation Guide Test your system to insure all connections are correct and the speakers are active. These speakers are designed with adjustable tweeters. The tweeters can be rotated or pivoted if desired. The angle of the tweeters can be adjusted diametrically and to a maximum of approximately 20 degrees off axis.
