SUBWOOFER ADJUSTMENT & USE SUBWOOFER INITIAL CONTROL SETTINGS - Set the LOW PASS FREQUENCY Control to its center position. - Set the LEVEL Control fully counterclockwise to MIN. You-ll reset this controlafter you make other adjustments. ADJUSTING THE SUBWOOFER CONTROLS - Play a program on your system. For the following adjustments, use the D\ olby ProLogic Normal surround mode and select a movie that has a Dolby Surrou\ nd soundtrack with a lot of music, or play a music CD. Adjust the receiver\ -s volume control for a comfortable sound level from the system speakers. - Increase the Subwoofer-s LEVEL Control setting clockwise, so that you hear the deep bass. Adjust the control for a natural, musical balance that has p\ lenty of deep bass sound when it is actually present in the music. - Listen carefully to bass voices and, if needed, adjust the LOW PASS FREQUENCY Control so that they sound natural. Setting the frequency too\ high will make deep voices sound excessively -chesty- or resonant \ and will give the upper bass in music a -one-note- quality. Setting the frequency too low will make deep voices sound -thin- and will give music a lack \ of -warmth-. - Make fine adjustments until the program has satisfying and natural sound\ quality on both bass voices and music. MOUNTING BRACKETS THE HC5 speaker set comes with a wall mounting system specifically desi\ gned for your HC5 satellites. The mounting system includes four each mounting rod\ s with attached plate, rubber compression washers. and angle wedges. The system\ DOES NOT include hardware to attach the wall mount brackets to the mounting surfa\ ce. When installed properly, the mounting system will allow the listener to focus the satel- lites on the chosen listening location or sweet spot. Take the satellite in hand and view the rear panel. You will note that the top and bot- tom caps are protruding. The bottom cap has a formed hole that passes th\ rough it. Press one of the compression washers into the opening, being sure to all\ ow the edge mold on the washer to overlap slightly on both sides of the cap. Place t\ he free end of on mounting rod into the washer from the bottom, rotate the satellite an\ d push the rod slowly. Be sure not to dislodge the washer from its location. Continue to push\ until the rod enters the insert on the inside of the top cap. You can now rotate the satellite hor- izontally on the rod to access the mounting plate and complete the brack\ et installation. Once the plate is attached to the mounting surface, the satellites can b\ e easily rotat- ed to the desired orientation. The compression washer will assist in hol\ ding the satel- lite in the desired position. If you require a vertical adjustment a wed\ ge insert is pro- vided and is designed to be placed between the plate and mounting surfac\ e. TROUBLESHOOTING SUBWOOFER POWER INDICATOR LED DOES NOT LIGHT - Check that the Subwoofer-s POWER Switch is in the AUTO ON position. - If the POWER Switch is in the AUTO ON position, check the AC outlet the Subwoofer is plugged into to be sure that it is live. You can use a tester or plug-in a lamp to check it. - If the AC outlet is live, either the power cord or Subwoofer has a probl\ em. Unplug the power cord from the AC outlet and check the fuse by unscrewin\ g the center piece from the holder. If it is blown, replace the fuse only with a fuse of the same type and rating. If this doesn-t help, take the Subwoofer to your dealer for service - THERE ARE NO USER SERVICEABLE PARTS INSIDE. NO SOUND FROM THE FRONT SPEAKERS. - Be sure the Receiver and Subwoofer POWER Switches are in the On position\ s. - Check the Receiver-s Volume Control Setting - if it is all the way down, there won-t be any sound. - Check that the Receiver-s Input Selector is set to an active source of audio signals and that a Tape Monitor Loop is not engaged. - Be sure that the Receiver-s Speaker Selector switch is turned on to the terminals [A or B, 1or 2] that you have your Front speakers connected to\ . If the Receiver has a headphone jack, you can use headphones to check the Recei\ ver for output. - Check the wires and connections from the Receiver-s Front Speaker Output terminals to the Subwoofer-s SPEAKER-IN terminals. - Try removing the Subwoofer from the system, leaving your Front speakers connected to the Receiver. If there still is no sound, take the Receiver to your dealer for service. NO SOUND FROM THE SUBWOOFER - First, be sure there is sound from the Front speakers and that the Recei\ ver is working correctly as outlined above. - Check the Subwoofer-s LEVEL Control. If it is all the way counter clockwise, there may be no sound. - The Subwoofer only reproduces deep bass sound. If the program has no d\ eep bass, the Subwoofer will not make any sound. Play a program with plenty\ of bass, such as jazz or rock music, or an action movie. - If everything else checks OK, take the Subwoofer to your dealer for service - THERE ARE NO USER SERVICEABLE PARTS INSIDE.

HC5S and HC5B SURROUND SYSTEM Contents of Carton: 4 each 2-way Matching Satellites , Shielded 1 each 2-way Center Channel, Shielded 1 each Subwoofer CENTER AND SATELLITE SPEAKERS Your five surround speakers consist of 4 matching Satellites and a Center Channel Speaker. The Satellites are the smaller set while the Center Channel has a horizontal orientation. SUBWOOFER Your Subwoofer delivers powerful, deep bass sound output for a natural, life-like sonic experience. Please follow the directions in th\ is manual to achieve the best performance from your system. HOW TO PLACE YOUR SYSTEM COMPONENTS Locate the Center Channel on top of or under the television or monitor. One of the Satellite Speakers should be located on either side of the television. Your Subwoofer must sit on the floor, in a corner to work properly. The floor and corner are actually a part of the Subwoofer-s design. Place your Subwoofer in the corner nearest your system-s electronic components to keep wire or cable runs short. CONNECTING THE SURROUND SPEAKERS Your Receiver will have clearly marked terminals for connecting the Satellite and Center Channel Speakers. The \ most common type of connection is spring loaded. Press down on the tab and insert the stripped wire tips into the opening. IMPORTANT: Always connect the red (+) terminal on the Receiver to the red (+)\ terminal on the corresponding Speaker i.e. Front Left. Connect the corre\ sponding black (-) terminal on the Receiver to the black (-) terminal on the same S\ peaker. Continue until all of the speakers have been connected in this manner. SUBWOOFER CONTROLS & CONNECTIONS POWER CORD Plug the power cord into an AC wall outlet or other AC outlet capable of supplying at least 400 Watts. POWER SWITCH Turns the AC supply completely OFF or sets the Subwoofer to AUTO ON operation. In AUTO ON, the Subwoofer is in standby mode until it det\ ects an audio signal input, then the Subwoofer turns on automatically. A few minutes after audio input signals cease, the Subwoofer automatically returns to standby mode\ . POWER INDICATOR LED This LED is unlit when the AC power switch is OFF. It glows red when the Subwoofer is in standby mode ad green when the Subwoo\ fer is on. FUSE 250V 2A This fuse protects against internal and external faults. If the POWER switch is ON and the power indicator LED is unlit, unplug the power cord\ from the AC and the back of the amplifier, then pry up the rectangular fuse holder and check the fuse. IMPORTANT If the fuse is blown, replace it only with a fuse of the same type a\ nd current rating. L , R SPEAKER OUT & IN - See Connection Option 1 These terminals are for making connections using speaker wire. If you use this option, do not use Opti\ on 2. LINE IN & LINE OUT - See Connection Option 2 These are for connections using audio cables. If you use this option, do not use Option 1. LOW PASS FREQUENCY CONTROL Adjusts the upper frequency limit for audio sig- nals going to the Subwoofer amplifier. This control helps you adjust the system-s tonal balance. LEVEL CONTROL Balances the loudness of the Subwoofer relative to the Front speakers and compensates for room effects on the Subwoofer-s output. PHASE SWITCH The Phase Switch controls the phase of the Subwoofer-s output relative to the front speakers. Listen carefully to the sound quality while playing a CD with low bass. Select the position of the switch that produces the fullest deep bass without boominess. You may need to readjust the Level and Low Pass Frequency controls after setting the Phase Switch. CONNECTING YOU SUBWOOFER IMPORTANT: When you make connections. make sure that the power switches of all components, including the Subwoofer, are OFF. AUDIO CABLES If you are connecting the Subwoofer into a system made up of separate components (preamp & power amps), you will need audio cables long enough to reach the Subwoofer from the preamplifier and the power amplifier. SPEAKER WIRE Typical speaker wire has a pair of separate conductors with insulating jackets that are molded together. We recommend that you use 16-gauge speaker wire for hooking your Receiver to your Front speakers. To make connections to the Subwoofer in parallel with the Front speakers easier, the speaker wire connecting the Receiver to the Subwoofer can be smaller (h\ igher gauge number), since the Subwoofer does not draw large amounts of power throu\ gh these wires. POLARITY All speakers in a system must be connected with the same polarity. Speaker wire is marked for polarity so that you can identify which wire \ in the pair is which. Polarity is shown by a color strip on the insulation, by ridges \ molded into the insulation, or by the colors of the wires - one copper and one silver. Strip the insulation from speaker wire ends to reveal the bare conductor\ s before connecting to Receiver, Subwoofer or Speaker terminals. IMPORTANT Always connect the red + terminal on the Receiver to the red + terminal on the Subwoofer, and the black - terminal on the Receiver to the black - terminal on the Subwoofer. The same is true for hooking the Receiver outputs to the Front speakers: red + to red +, and black- to black-. IMPORTANT USE OPTION 1 OR OPTION 2, NOT BOTH . OPTION 1 - CONNECTION WITH SPEAKER WIRE Connect speaker wires from the Receiver-s front left and right speaker outputs to the Subwoofer-s Speaker Level-In connections. Connect left channel to left input and r\ ight channel to right input. You have the option of connecting your main speakers to the speaker B outputs on your Receiver, if it is so equipped or you also have the option of connecting your main speakers using the connections on the Subwoofer. This will pass the audio signal to your main speakers, except the low bass which will b\ e produced by your Subwoofer. To use this connection option, connect your main speakers to the right and left outputs on the Subwoofer (see illustration 1). Be sure you ta\ ke care to main- tain proper signal polarity, red to red and black to black. OPTION 2 - CONNECTION WITH AUDIO CABLE Connect a pair of audio cables from the preamp-s output jacks to the subwoofer-s LINE IN jacks. Connect left channel to left to left and right channel to righ\ t. Connect a pair of audio cables from the subwoofer-s LINE OUT jacks to the power amplifier-s input jacks. Connect left channel to left and right channel to right. If your preamp receiver or processor has a subwoofer or mono output jack\ that is controlled by the master volume control, use a single audio cable to con\ nect that output to the subwoofer-s Line-In jack. No audio cables from the subwoofer-s Line- Out jacks are needed in this set-up.
