MAESTRO M9
Dolby Atmos
The Maestro M9 allows up to four extra speakers to be used for the Dolby
Atmos system. One or two pairs of speakers (known as Height 1 and
Height 2) can be used to create a soundfield above the listening position,
allowing you to be surrounded in an amazing “dome of sound.” Dedi-
cated speakers for this application can be mounted in the ceiling, or
pointed at the ceiling to give a reflected field. We recommend that
you research information directly from Dolby Laboratories about
this wonderful system. The Height 1 and Height 2 line-level outputs
are used to feed external amplifiers to power your passive speakers.
If you are not using the surround back balanced outputs, these can be
used to feed a power amplifier powering the Height 1 pair.
If you are using just one pair of speakers, connect them as Height 1, and
locate them approximately half way between the listening position and
the display, either ceiling-installed, or reflecting off the ceiling. If you
are using Height 1 and Height 2 speakers, then the Height 1 pair
would be located a little forward of the display screen, and Height
2 pair would be just in front of your listening position.
This is just an overview, so do your research carefully and talk with
your dealer.
Connection Tips
Even if you’re an electronics veteran, this part may seem repetitive, but
some things can never be repeated too many times.
• Turn off all components before making or undoing any connections.
• When making connections, make sure that “left goes to left” and “right
goes to right.” The obvious and time-honored way to assure this is to assign
RED plugs to Right and WHITE/GREY/BLACK plugs to the left. Yellow is
usually used for video cables or digital audio connections.
• Wherever possible, keep power cords away from signal cables (i.e., inputs
from disk players, VCRs, etc.) to prevent induced hum. Bundle all power
cords down one side of your equipment cabinet and all the signal cables
down the other.
• Use high quality interconnect cables. We’re not going to get into the de-
bate about whether $100 per meter interconnects improve the sound and
picture quality of your system. We do know from experience however that
really, REALLY cheap connections can cause problems.
• Don’t stand in a bucket of water when working with electricity. This not
a good day to wash the dog, or have a water balloon fight.
