4.2
Loudspeaker Protection Circuit
The Pure groove PG218 has built in overload protection on each woofer. This protection-unlike other manufacturer's
protection-does not affect the audio at all, unless there is an overload condition. So under normal operating conditions, it does
nothing. But when the signal is too high for too long, it will engage and keep the drivers at a safe operating area. This is a
thermal based circuit, so it engages slowly and will automatically reset when the overload is removed. You may see a faint
glow from inside the cabinet when it is operating. If you see a bright light, then the level is too high and should be
reduced in order to maintain full dynamic range of the signal.
It is extremely unlikely that you can damage the loudspeaker from applying excessive power-but it might be possible under
certain circumstances. Think of it as the air bags in your car. They can protect you in most normal accidents-but if you drive
the car off of a cliff-don't expect them to save you. Proper operation is the best way to ensure long life.
4.3
Operator Responsibility
It is the responsibility of the operator to maintain safe operating levels and to insure that the audience is not harmed by excessive
levels. This is a chart of the recommended exposure limits set by OSHA.
4.4
Aqua Tight Coating
Aqua Tight Coating includes full two layer fiberglass finish for maximum moisture resistance as well as a special polyurea coat
bonded to the fiberglass exterior & two topcoat layers of UV resistant color stabilizer. It also includes all stainless steel exterior
fasteners, an acoustically transparent moisture barrier to the grille, waterproofing the driver cones and sealant for the input plate,
handles or cabinet fixtures. The finish also includes a powder coated stainless steel grille, sealed, waterproof cable leads (12'
length standard), and fully caulked all external joints (except for the "weep" opening at the bottom of the grille).
If a repair is to be made on a loudspeaker with "AT" finish, a few steps must be taken to insure the speaker remains water
resistant in future usage. The caulking must be removed to free the grill and driver access panels. Once the repair is finalized,
the bolts must be coated with silicon and the caulk must be replaced on all panels that have been removed.
