Using the Sine/Sub/Sens controls

This section explains how to use the Sine/Sub/Sens controls to check for room resonances, adjust the subwoofer crossover frequency, or adjust the sensitivity of the analogue sources.

To display the Sine/Sub/Sens controls

•If necessary, unlock the digital surround controller as described in Configuration Wizard, page 25.

•Press Xovr- or Xovr+ to decrease or increase the crossover frequency.

The display shows the current crossover frequency:

CD Xover 85Hz

Sine -Xover+ -Sens.+

• Press More until the bottom line of the display shows:

Subwoofer crossover frequency

The G68 Digital Surround Controller allows the crossover frequency for any subwoofers which you have to be adjusted between 30 and 150Hz. The crossover can be set independently for Music, Logic, and 5.1 Movie layouts. The default is the THX standard of 80Hz.

To adjust the subwoofer crossover frequency

•Select a source, then display the Sine/Sub/Sens controls as described above.

For THX loudspeaker systems you should not adjust these settings; they should be left at 80Hz. 80Hz is also the recommended setting for all movie listening. You may prefer, however, to lower the crossover frequency for music if the main speakers have good bass handling down to, say, 50Hz.

Sinewave sweep test

The G68 includes a sinewave signal test, to help you set the subwoofer crossover frequencies, or check for room resonances.

Warning: This test is very loud. Very loud low-frequency signals may damage the speakers.

To use the sinewave sweep test

•Select a source, then display the Sine/Sub/Sens controls as described above.

•Press Sine to turn on the sinewave signal.

The display shows:

CD Sine 80.0Hz
