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.
Tilting the Speaker...
If needed, the enclosed stand allows you to tilt the speaker across a
25-degree range (i.e., 18° maximum up and 7° maximum down), as
shown in Figure 3.
Surround Modes...
Important!
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”.
Do not exceed the tilt range. Doing so may cause the speaker to fall
out of its stand.
TILT DOWN
(WHEN ON TOP OF
A LARGER TV)
NO TILT
TILT UP
(WHEN BELOW TV)
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.
DO NOT EXCEED MAXIMUM
DOWN-TILT (WHEN BOTTOM
OF GRILLE TOUCHES BUMPER)
DO NOT EXCEED MAXIMUM
UP-TILT (WHEN TOP OF
GRILLE IS LEVEL)
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.
FIGURE 3 The Prelude MTS center channel can be tilted up or
down in its stand.
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.
