Your StudioMonitors should sound good right out of the box; howev-
er, an extended break-in period of 20-40 hours or more of normal play-
ing is required to reach full performance capability. Break-in allows the
suspensions to work in and results in fuller bass, a more open “blossom-
ing” midrange and smoother high frequency reproduction.
The StudioMonitors are mirror imaged (serial numbers have either
an A or a B) with the side mounted, pressure coupled subwoofers
located so they may be set up with both woofers facing in (toward
each other) or both woofers facing out (away from each other). (Feel
the side of the speakers to determine which side the woofer is on.)
Facing the woofers in or out will vary the sound somewhat and which
way is best will vary with your room. Again, experiment to determine
the best location for the speakers. If you use a StudioMonitor for a
center speaker, you may use either a speaker A or speaker B, and it
may be positioned either vertically or horizontally. If it is used hori-
zontally, make sure the subwoofer is facing up.

Hooking Up Your StudioMonitors
Your StudioMonitors each have one pair of gold 5-way binding
posts. Normally, you will hook up the left main/front channel red(+)
terminal of your receiver or amplifier to the red(+) terminal of your
left StudioMonitor and the left main/front channel black(-) terminal of
your receiver or amplifier to the black(-) terminal of your left
StudioMonitor. Connect the right channel main/ front channel red(+)
terminal of your amplifier or receiver to the red(+) terminal of your
right StudioMonitor and the black(-) terminal of the right main/front
channel of your receiver or amplifier to the black(-) terminal of your
right StudioMonitor. If your receiver/decoder has a bass management
system and you are using a separate subwoofer, set bass management
to “Small
” left and right main speakers and “Yes” subwoofer. If you
are not using a separate subwoofer, set bass management to “Lar
ge”
left and right main speakers and “No
” subwoofer.
