USE OF THE LQ10P

FLYING THE LQ 10P

Caution: Suspending or flying the Crest LQ 10P must be done by a certified structural engineer.

Important Safety Information for Mounting Crest LQ 10P speaker systems:

Caution: Before attempting to suspend these speaker models, consult a certified structural engineer. Speakers can fall from improper suspension, resulting in serious injury and property damage. Other enclosures may not be suspended below one, nor should additional weight be suspended from one of these units. Use only the correct mating hardware. All associated rigging is the responsibility of others.

Always use all four inserts of a given group as a set; NEVER use just one insert to fly a cabinet! The four insert groupings are a top group of four and a bottom group of four. Some models also have a group of four on the rear plane of the cabinet.

Maximum enclosure angle from vertical hang: 30˚

Always loop a suitable safety chain or wire rope through the top handle and firmly attach it to a suitable structural member as indicated by a certified structural engineer.

The recommended range of torque for the mounting bolt is 3 to 3-1/2 lb./feet of torque. DO NOT OVERTIGHTEN! If an insert spins, it has been damaged and the cabinet cannot be flown!

Never transport the cabinet while mounted on an array bracket or other mounting bracket.This may unduly stress the mounting inserts.

WARNING! (note to structural engineer)

For the Crest LQ 10P, the thread insertion depth of the end of the mounting bolt should not be more than 5/16" past the surface of the cabinet.

If this thread insertion depth is exceeded, then the inserts may be damaged or unseated from the cabinet, severely compromising its mounting integrity!

The correct mounting bolt diameter and threads per inch are: 1/4" x 20. Use of a grade five bolt is recommended.

GETTING AC POWER TO THE CREST LQ 10P

The LQ 10P comes with an 8' IEC connection AC power cord.When using an extension cord, ensure that it is no longer than necessary and is of a sufficient current capacity to maintain safety. High current, properly-sized extension cords will maximize the power output capability of the LQ 10P’s internal amplifiers. For best results, do not power anything else from the extension cord used to power the LQ 10P.This minimizes the voltage drop that all extension cords cause. Running just one extension cord back to the wall plug for the entire sound system is not the way to maximize sound system performance.The third wire ground plug on the AC plug should NEVER be removed or broken off.This seriously compromises safety.
