SMS1 Instruction Manual Rev C Page 7
If you choose to use the binding posts, be careful to keep all connections properly polarized
(connect + to + and - to -). Do not turn the power amplifier on until all binding-post connections
are secured.
BI-AMP Switch
The BI-AMP switch must be set to NORMAL for most applications. It must always
be set to NORMAL when using the binding posts. If this switch is in the wrong
position, the high-frequency driver may not receive an input signal.
Break-In Period
The SMS1 speakers require a 20 to 30 hour break-in period to reach full
performance. Speaker drivers are electro-mechanical devices and the materials used in these
devices undergo minor mechanical changes during the break-in period. You should hear increased
energy in the lowest octave, and a more relaxed midrange, when the break-in period is completed.
Proper Care
Your speakers carry a warranty against defects. However, the warranty does not cover failure from
abuse. Please use good judgment.
Tweeter failures are often related to underpowered or overdriven systems. A clipping power
amplifier can produce unusually high levels at the input to the tweeter. Do not touch the silk-dome
tweeter. It is very delicate and is easily damaged.
The woofer can be damaged by excessive power.
Grill Removal and Insertion
The speaker grills are designed to protect the drivers from accidental contact while providing
excellent acoustic transparency. We recommend keeping the grills in place.
Each grill is attached with four press-fit pins and sockets. There is one pin on each corner of the
grill. Use extreme care when attaching or removing grills.
To remove grill:
 Grasp the bottom of the frame and gently pull the grill until the two bottom pins are free.
 Grasp the top of the frame and gently pull to clear the remaining two pins.
 Avoid twisting the grill frame when inserting or removing.
 Do not pull or press on the sides of the grill frame.
To insert grill:
 Grasp the top of the frame and gently insert the two top pins.
 Grasp the bottom of the frame and gently insert the two bottom pins.
 Avoid twisting the grill frame when inserting or removing.
 Do not pull or press on the sides of the grill frame.
