Subwoofer
The subwoofer is a large speaker that provides the bottom
end “kick” in the system. THX certified subwoofers are
rated by the cubic volume of the room. Make certain you
remember to include all spaces that open to the theater in
that volume calculation. Depending on the size of your
space, you may require more than one subwoofer to get
the bass volume levels that you desire.
Power
Like many of today’s intelligent home electronics, the
Maestro should be plugged into an unswitched AC outlet
so that it always has power. This allows the RS-232 and
remote control features to work even when the Maestro is
in standby. We always recommend the use a high quality
surge protection device to keep all of your electronics safe
from the evils of public power systems.
Audio Connections
Most of the sources will have two audio connections to the
Maestro; the 2 channel analog audio and the multi-chan-
nel digital audio. When given the option, you should
connect both of these audio signals to the Maestro. This
will provide the digital audio signal necessary for high-
quality digital surround sound along with the analog
audio for tape recording and the second zone audio
output.
Don’t worry if your satellite receiver has a coaxial digital
output and the Maestro SAT input is optical. Refer to the
advanced configuration section on page 3-9 of this manual
for more information regarding assigning a digital input to
the optical or coaxial connection.
Multi-Channel Analog Audio
Newer audiophile surround recording formats such as
SACD and DVD-A decode the multi-channel signals directly
within the player. The Maestro features an 8 channel direct
analog input for these sources. These inputs bypass the
digital circuitry in the Maestro and route directly to the
Main Amplifier outputs via its own volume control circuit.
This ensures the highest possible audio quality for this
input.
