OPERATION

Power On

Plug your subwoofer’s AC cord into a wall outlet. Do not use the outlets on the back of the receiver.

Initially set the subwoofer’s Level Control K to the “O” position.

Turn on your sub by pressing the power button 2 on the rear panel.

Turn on your entire audio system and start a CD or movie sound- track at a moderate level.

Adjust Gain

Turn your subwoofer’s Level Control K up to the “5” position (half way). If no sound emanates from the subwoofer, check the AC-line cord and input cables. Are the connectors on the cables making proper contact? Is the AC plug connected to a “live” receptacle? Has the power button 2 been pressed to the “On” position? (Note:The Level Control on the front panel will turn green when the power is on.) Once you have confirmed that the subwoofer is active, proceed by playing a CD, record or cassette. Use a selection that has ample bass information.

Set the overall volume control of the preamplifier or stereo to a comfortable level. Adjust the subwoofer’s Level Control K until you obtain a pleasing blend of bass. Bass response should not overpower the room but rather be adjusted so there is a harmonious blend across the entire musical range. Many users have a tendency to set the subwoofer volume too loud, adhering to the belief that a subwoofer is there to produce lots of bass. This is not entirely true. A subwoofer is there to enhance bass, extending the response of the entire system so the bass can be felt as well as heard. However, overall balance must

be maintained or the music will not sound natural. An experienced listener will set the volume of the subwoofer so its impact on bass response is always there but never obtrusive.

Crossover Adjustments

If you are using Method 1 as your connection method, you need to set the High-Level High-Pass Filter 5 to “On”or “Off.”When on, this adjustment limits the low frequencies that your main speakers will reproduce. If you would like your main speakers to also reproduce frequencies below 80Hz, you may set this switch to “Off.”If you are using speakers that do not reproduce low frequencies well, we recommend that you set the switch to “On.”

Low-Pass Filter Adjustment Control J – The Low-Pass Control determines the highest frequency at which the subwoofer reproduces sounds. If your main speakers can comfortably reproduce some low-frequency sounds, set this control to a lower frequency setting, between 50Hz – 100Hz. This will concentrate the subwoofer’s efforts on the ultradeep bass sounds required by today’s films and music. If you are using smaller bookshelf speakers that do not extend to the lower bass frequencies, set the Low-Pass Filter Adjustment Control to a higher setting, between 120Hz – 150Hz.

Note: This control will have no effect if the Low-Pass Filter Switch 9 is set to “Off.” If you have a Dolby Digital or DTS processor/receiver, the Low-Pass Frequency is set by the processor/receiver. So you should leave the Low-Pass Filter Switch 9 in the “Off” position. Consult your owner’s manual to learn how to view or change this setting.

Phase Control

The Phase Switch 8 determines whether the subwoofer speaker’s piston-like action moves in and out with the main speakers, 0˚, or opposite the main speakers, 180˚. Proper phase adjustment depends on several variables such as room size, subwoofer placement and listener position. Adjust the phase switch to maximize bass output at the listening position.

Final Positioning

After correctly connecting the Intermezzo 1.2s and verifying that both the subwoofer and main speakers are playing, it is time to optimize the system for your particular listening room. Earlier, you placed the subwoofer in its general location. Finding the exact location for optimum performance sometimes only involves moving the speakers up to a few inches in any direction. We urge you, therefore, to experiment with placement until your speakers deliver their full potential.
