m CO Testing the connections To make sure that the speakers are connected to your amplifier "in phase" - positive to positive, negative to negative - perform this simple test. 1. Set your sound system for MONO (monophonic) reproduction. Be sure the balance control is centered or set to normal. 2. Temporarily place the speakers close together, facing each other. 3. Now, play some deep bass music over the system. If your speakers are correctly phased. the sound will appear to come from between the speakers, providing full, natural bass response. 4. If the music seems to be lacking in deep bass, reverse the + and - wire connections on one speaker and repeat the test. Use the connection that produces the most powerful bass. Amplifier/receiver considerations Your 2.21'speakers incorporate heavy-duty driver elements designed to resist many types of electrical stress. However, any speaker can be damaged if the amplifier driving it should fail. Speaker damage may also occur by playing the music so loudly that it sounds distorted. This can happen even with a low-powered amplifier or receiver. Your 2.2 speaker system is designed for ui with amplifiers or receivers rated from 10 t 120 watts per channel. For further information, refer to your amplifier or receiver owner's guide. Cleaning your speakers The 2.2 Speaker enclosures can be wiped clean using a soft cloth dampened with a mild detergent. The grille panels require no special care, but may be removed and vacuumed if necessary. Grip each grille by its edges and pull gently to remove. No other maintenance is required. • 4
