Instruction Manual

You can connect your speakers by using a variety of audio connectors such as banana plugs (single or double), pin connectors, spade lugs, etc., or you can:

1.Remove ½" of insulation from each wire end.

2.Twist the stranded wire together, keeping the two ends separate.

3.Place the appropriate wire through the appropriate postholes in the connectors. These holes are revealed when you loosen the connector’s capscrew.

4.Screw down the capscrew tightly, but be careful not to over tighten it.

5.Check the tightness of the capscrews 24 hours after hookup and occasionally after that, as they can loosen over time.

We recommend that you check your local electrical codes to make sure that you are not using improper connectors.

It’s important to observe polarity while making speaker connections: red

(+)terminals on the amplifier to red (+) on the speaker, black (–) on the amplifier to black (–) on the speaker. Look carefully at the wires you are using and note that one of the conductors of each pair will typically be identified by color, printing on the outer jacket, ridges on the outer jacket, or a thread intertwined with the wire strands. By convention, the marked wire is connected to the red (+) terminal.

Whether your are connecting a complete system,or adding a single speaker component to your present system, the wiring should look like one of the system wiring diagrams on pages 7 and 8.

Warning: Before turning on the amplifier, be certain that no stray wire strands are touching across any terminals as this might damage

Operation of the Rear Panel Controls on the LCR Speakers

This control changes the tilt or roll-off slope of the tweeter. It has been designed to help com- pensate for different room acoustics. The THX/ Average position is intended for rooms with a reasonable combination of reflective (hard) and absorptive (soft) sur-

faces. The Reverberant position is designed for rooms with an abundance of reflective surfaces like hardwood or tile floors,glass walls,etc.It decreases the high frequency output of the speaker to reduce excess HF energy that builds up in live rooms. The Damped position brings the tweeter’s output slightly above flat response to compensate for overly absorbent rooms with lots of soft surfaces.Speakers in overly damped rooms can sound dead and lifeless unless compensated.

Looking through the mate- rial into the light can give you some indication of the material’s transpar- ency in this regard. The more light and detail you can see, the better it will be acoustically.

your amplifier.

Finally, check the polarity of your front speakers by listening to some ste- reo music with good bass content. If the sound seems“hollow”, unusually spread out, or seem to have weak mid-bass, recheck your connections for proper polarity and correct any out of phase connections, if necessary.

Use this switch to adjust the lower midrange output of the speaker to compensate for the typical sound colorations caused by placing the speaker close to a TV screen or building it into a wall unit or cabinet.

System Setup

Bass Management

Some older surround sound decoders and receivers offer a choice of “Nor- mal” or “Wide-band” modes for the center channel speaker. The Model 8200e and 6200e C are designed to be used in the Normal mode.Addition- ally,digital processing multi-channel systems provide a Bass Management menu, which typically requires you to select between “Small” or “Large” speakers during system set-up. Since these systems have been designed to work with a dedicated subwoofer, please set all the speakers in Systems 6200e and 8200e to Small.

To set these controls, sit in the prime listening position and have someone switch between the compensation choices, using well recorded dialogue or musical instrument recordings. Choose whichever switch position sounds most natural and real to you.

NOTE: Although these controls have been designed to compen- sate for various acoustic room anomalies, we recommend that you try them to hear the difference that they make in the sound of the system. For any number of reasons, you may decide that you prefer them set in a particular manner inconsistent with your room’s acous- tics, but sounds best to you. Experiment. It will be worth it.
