Setting Your Speakers’ Low-Frequency

Level Control

Your Mythos STs have a level control which allows you to perfectly tune the output level of the powered low frequency subwoofer section to match your room as well as to fulfill your own personal listening preferences. Please note that there are no controls to vary the crossover points or phase because these have been factory calibrated and set to provide perfect blending (a major performance benefit of this innovative product). We suggest beginning with the level control set at approximately 1 o’clock.

VERY IMPORTANT: Setting Channel Balance and Bass Management Systems

Dolby Digital and DTS 5.1 (6.1, 7.1) systems and decoders have a critical channel balancing procedure for the left and right front speakers, center channel, rears and subwoofer (if it is hooked up through the “LFE or Sub Out” low-level connection) which must be followed if the system is to perform properly. We have spoken with many system users with problems relating to the overall sound of their system which could be clearly traced back to improper system balance. In fact, many users never realize that there is a system balance procedure to be followed.

Also note that Dolby Digital and DTS 5.1 (6.1, 7.1) systems and decoders have bass management systems (systems which direct the bass to the various channels) which vary from unit to unit. This bass management system must also be properly adjusted. We have spoken with many system users with problems relating to the overall sound of their system which could be clearly traced back to improper bass management. In fact, many users never realize that there is a bass management procedure to be followed.

Your receiver or decoder’s bass management system should be set for “Large” left and right main speakers and “Yes” subwoofer. If you have a Definitive center channel with a built-in powered subwoofer, set your decoder’s bass management center channel setting to “Large” (although you should experiment with this to see what sounds best in your specific system). If you are using large rear surround speakers with very extended low frequency response such as a large Definitive floor-standing system or one with a built-in powered subwoofer, set the rear channels of your decoder’s bass management system to “Large.” If not, set them to “Small.”

Setting Low-Frequency Balance When Using Separate LFE Input

We suggest that when you are using a separate LFE input, you set the bass level on your Mythos STs to sound balanced when listening to music in stereo and use the .1 channel or bass level control in your Dolby Digital channel balancing
