red (+) terminal of your right surround loudspeaker and the black (-) terminal of
the right surround channel of your receiver or amplifier to the black (-) terminal
of your right surround loudspeaker. Most speaker wire has some indicator (such
as color-coding, ribbing or writing) on one of the two conductors to help you
maintain consistency. It is essential to connect both speakers to the amplifier in
the same way (in phase). If you experience a lack of bass, it is likely that one
speaker is out of phase with the other and needs to be rewired paying closer
attention to connect positive to positive; negative to negative on both channels.
Set the receiver’s or processor’s Speaker Set-Up menu as Surround = Large.
Your Mythos STSs contain a built-in, active powered subwoofer section as well
as an electronic crossover and must be plugged into an electrical socket of the
appropriate voltage (as indicated on the back of your unit) using the electrical cord
which you have attached to the bottom of the speaker. The Mythos STS has a
special circuit which automatically turns the powered subwoofer section on when
a signal is fed to the loudspeaker and does not require an on-off switch. Please note
that if you hear a pop from the speaker when the amp powers up, this is normal.
The LED on the back panel will light up when a signal is sensed and the amplifier
turns on. After the cessation of a signal, it may take up to an hour for the amplifier
to actually turn off. In some instances, because of stray radio signals (RF) in your
area, the LEDs may not turn off. However, this is nothing to be concerned about
as the amplifiers draw almost no power when they are idling.
Setting Your Speakers’ Low-Frequency Level Control
Your Mythos STSs have bass level controls which allow you to tune the output
level of the powered subwoofers to match your room and 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.
Normally the level control of the left speaker will be set the same as the level
control of the right speaker. However, these controls can also be set differently on
the two speakers in order to allow you to vary the response of left and right speakers
to compensate asymmetrical positioning of the speakers in your room (i.e., when
one is closer to a side wall or corner, etc.). This is a useful feature which allows you
much greater flexibility in loudspeaker placement, as well as the ability to
compensate for what could otherwise be difficult placement situations.
