Polarity is indicated by a color stripe on the insulation, by ridges molded into the insulation, or by the colors of the wire - one copper and one silver. Strip the insulation from the speaker wire ends to reveal the bare conductors before connecting to a speaker, subwoofer or receiver. Always connect the red (+) terminal on the receiver to the red (+) terminal on the Subwoofer, and connect the black (-) terminal on the receiver to the black (-) terminal on the Sub- woofer. The same is true for hooking up the Receiver outputs to the Front speakers: red (+) to red and black (-) to black. page 6 HT60.book Page 7 Monday, April 2, 2007 6:28 PM HT60 Subwoofer/Preamp Controls & Connections The amplifier and subwoofer controls are located on the back of the subwoofer cabinet, shown in Figure 3. FIGURE 3 -Subwoofer/Preamp Controls & Connections page 7 HT60.book Page 8 Monday, April 2, 2007 6:28 PM • Power cord: Plug the power cord into an AC wall outlet. • MODE (AUTO ON/OFF): Move this switch to turn the AC supply OFF/ ON. When AUTO ON is selected, the Subwoofer remains in the stand-by mode until an audio signal is detected. (During standby mode, the front LED indicator remains un-lit, while the rear indicator is illuminated red.) After a few minutes without an audio signal, the Subwoofer automatically reverts to stand-by mode. • SUB/LFE: Move this switch to select LFE or SUB (normal subwoofer) mode. Select LFE mode if you are using your receiver’s LFE output. • POWER: The green LED POWER indicator on the front illuminates blue and the LED indicator on the back illuminates green when the amplifier is turned on. • Fuse: The 250v 2.0A (AGC Type) is located on the amplifier panel on the back of the Subwoofer cabinet under the power cord. This fuse protects against internal and external faults. If the Power switch is ON but the power indicator LED remains unlit, the fuse should be replaced. To replace the fuse, unplug the power cord from the AC outlet, then unscrew the center piece and replace the fuse. IMPORTANT: If the fuse is blown, replace it ONLY with a fuse of the same type and current rating (250v 2.0A). Severe damage or fire could result from improper fuse replacement. • SPEAKER LEVEL IN/OUT (L and R): These terminals are used for making connections with speaker wire. • LINE LEVEL IN/OUT (L and R): These connections are used for bass audio signals. • CROSSOVER FREQUENCY: Adjust the system’s tonal balance by setting the upper frequency limit (40Hz-180Hz) for the audio signals going to the subwoofer. • SUBWOOFER LEVEL: Balance the loudness (OFF, or -30dB to +9dB) of the subwoofer relative to the front speakers and compensate for room effects on the subwoofer. • PHASE: Control the phase of the subwoofer relative to the front speakers. To determine the appropriate phase setting, select either regular (0°) or inverted (180°) and perform a sound test. Listen carefully to the sound quality while playing a CD with low bass such as percussion or bass lines, then select the position that produces the fullest and most dynamic bass. You may need to adjust the LEVEL control (volume) and the CROSSOVER FREQUENCY control after setting the PHASE switch. page 8 HT60.book Page 9 Monday, April 2, 2007 6:28 PM HT60 Installing your Surround Speakers The surround speakers are identical and can be used for any channel. Surround Speaker Placement Speaker placement is critical, and can make the difference between good and great sound quality. For optimum sound quality, position your front (main) surround speakers slightly in front of the video screen and turn them slightly inward (towards the center of the listening area). This reduces the possibility of reflection from the video screen or side walls. Turning the surround speakers farther inward produces a smaller sound stage and focuses the sound more directly to the listener's ear. Turning them less or not at all produces a larger sound stage and compromises localization of the sounds. Placing the left and right surround speakers closer to the front wall, side walls, or corners will increase the amount of audible bass. The HT60 surround speakers are designed to be placed within 18 inches of a wall for optimum tonal balance. Rear speakers should be placed approx at ear level or slightly higher. The center channel speaker should be placed above or below the television. Based on your listening preferences, you will want to experiment with the placement of your surround speakers. When possible, the surround speakers should be installed at the same level as the listener's ears. See “Surround System Configuration” on page 5 for more information onspeaker placement. Connecting the Surround Speakers Strip approximately 3/8" of the insulation from the speaker wire, exposing the bare conductors. Twist each end of the speaker wire, and then connect the speakers in phase. Connect the positive (+) terminal from the Receiver to the positive (+) terminal on the speaker. Red typically indicates posit...
