JBL MS 8 Owners Manual

CALIBRATION/setup
6. If in Step 2 you selected 2 way
a) The MS-8 will display Front Lo/Hi Xover. This screen enables you to choose the
crossover frequency between the front midrange and tweeter (or between a
separate midbass driver and a midrange/tweeter). Use the Left and Right navigation
buttons to display a frequency between 50Hz and 10kHz, and press the Select
button to select it. If you’re using separate tweeters connected to the MS-8’s
amplifier or to an additional amplifier, we recommend using a setting of 3500Hz
or higher.
b) The MS-8 will then display Front Lo/Hi Slope. This screen enables you to choose
the rate of attenuation of the filter between the midrange and tweeter. Use the Up
and Down navigation buttons to highlight a filter slope, and press the Select button
to select it. If you’re using separate tweeters (as discussed in Step 5a), we
recommend using 24dB/octave.
7. If in Step 2 you selected 3 way
a) The MS-8 will display Front Lo/Mid Xover. This screen enables you to choose the
crossover frequency between the front midbass and midrange. Use the Left and
Right navigation buttons to display a frequency between 100Hz and 10kHz, and
press the Select button to select it. The design and performance of your front
speakers determines which frequency you should choose.
b) The MS-8 will then display Front Lo/Mid Slope. This screen enables you to choose
the attenuation rate of the filter between the midbass and midrange. Use the Up and
Down navigation buttons to highlight an attenuation rate, and press the Select
button to select it. The design and performance of your front speakers determines
which rate you should choose.
c) The MS-8 will then display Front Mid/Hi Xover. This screen enables you to choose
the crossover frequency between the front midrange and tweeter. Use the Left and
Right navigation buttons to display a frequency between 200Hz and 10kHz, and
press the Select button to select it. The design and performance of your front
speakers determines which frequency you should choose. If you’re using separate
tweeters connected to the MS-8’s amplifier or to an additional amplifier, we
recommend using a setting of 3500Hz or higher.
d) The MS-8 will then display Front Mid/Hi Slope. This screen enables you to choose
the attenuation rate of the filter between the midrange and tweeter. Use the Up and
Down navigation buttons to highlight an attenuation rate, and press the Select
button to select it. The design and performance of your front speakers determines
which rate you should choose. If you’re using separate tweeters (as discussed in
Step 7c, above), we recommend using 24dB/octave.
Center Speaker
1. The MS-8 will then display Xover Setup > Sub , Front , Center. Select Center.
2. The MS-8 will then display Center, with the options None, 1 way, 2 way. Use the Up
and Down navigation buttons to highlight one of these options, and press the Select
button to select it. The configuration of your system’s center speaker determines
your choice.
For example: If your center speaker system consists of a coaxial speaker or
component with its own passive crossover connected to one of the MS-8’s outputs
(either its speaker outputs or its line outputs connected to an outboard power
amplifier), choose 1 way. If your center speaker consists of a component system
where the tweeter and the midrange will each be connected to separate MS-8 output
channels, choose 2 way.
