25-degree range (i.e.,18° maximum up and 7° maximum down),as
shown in Figure 3.
Important!

out of its stand.

W IRING THE S YSTEM
After placing the speaker,you are ready to connect it to your system.
First,turn off all audio-system power.Use high-quality speaker wire
to make the connections.Consult the owner’s manuals,included with
your amplifier or receiver,for connection and operation procedures.
Surround Modes...
When using the Prelude MTS Center in a Dolby* Digital or DTS®
home-theater system,make sure the receiver’s/processor’s center-
channel speaker modes are set to“Small”. When using the Prelude
MTS Center in a Dolby Pro Logic* home-theater system,make sure
the receiver’s/ processor’s center-channel mode is set to“Normal”.
Wiring and Polarity...
The Prelude MTS Center speaker has gold-plated terminals that
can accept either bare wire or banana connectors.To ensure proper
polarity,connect each +terminal on the back of the amplifier or
receiver to the respective +(red) terminal on each speaker,as shown
in Figure 4.Connect the –(black) terminals in a similar way.See the
owner’s manuals that were included with your amplifier or receiver to
confirm connection procedures.
Important!
Do not reverse polarities (i.e.,+to –,or –to +) when making
connections.Doing so will degrade the imaging and bass response of
the home-theater system.
After correctly placing and wiring the Prelude MTS Center and the
rest of your speaker system,adjust the levels for all of the channels
as recommended by the manufacturer of your receiver/processor.
