System Diagnostics
If you encounter an issue when setting up your SDA Pro
loudspeakers, follow these steps to troubleshoot and make
corrections as needed.
1. Start with facing speakers the directly forward and
equidistant from the wall.
2. Place a chair in the listening area centered between the
speakers.
3. To check for Absolute Phase, disconnect the (-) black wires
from your loudspeaker, leaving the (+) red wires connected.
Switch your amplifier to MONO operation or play MONO
source music. Rotate the balance control back and forth until
you find the lowest sound level. If this occurs near the 12 o'clock
position, your speakers are correctly in Absolute Phase.
If there is no sound at all, both speakers are out of Absolute
Phase and you will need to reverse the connections at either
the speakers or the amplifier so that red (+) on the speaker
corresponds the red (+) on the amplifier, and so on. If the
lowest sound level is heard with the balance control fully to
the left, the right speaker is out of phase. If the lowest sound
level is heard with the balance control fully to the right, the left
speaker is out of phase. Reverse the speaker connections at
either the amplifier or the out of phase speaker.
4. Reconnect the (-) black wires to your speakers. Return
the amplifier to STEREO operation, making certain that your
recording is in STEREO, and sit in the chair to listen for a few
minutes. You should hear sound that appears to come from an
area outside the two speakers, as well as sound that appears to
come from between the speakers. By manipulating the balance
control, you should be able to move the apparent sound source
from far outside the left speaker to far outside the
right speaker.
Caring for Your Legend Loudspeakers
Enclosure Finish
Your Legend enclosures are finished in real natural wood
veneer. Clean these panels periodically with a soft cloth and
furniture polish to remove dust and fingerprints. Never use
harsh detergents and cleaning fluids.
Note: Do not use any petroleum-based cleaners or solvents on
the loudspeaker cabinets.
• Clean wood panels with furniture polish and a soft
dry cloth
• Do not use furniture polish on black gloss lacquer
• Clean black lacquer veneer with a damp cloth

Baffle Smudges
Dust baffles with the included dust cloth or any other dry or
damp cloth (a damp cloth is one that has been sprayed with
a recommended cleaner, not one soaked with water). We
recommend you use a lint-free cloth.
Dusting the Baffle
Use a can of compressed air for the grille and/or baffle to dust.
Use a "computer keyboard" vacuum (only on the grille, not
the baffle).
