Professional audio store

Some professional audio stores rent "backline" equipment used in rock and pop shows, such as stage pianos and bass amplifiers.

Stores typically carry wireless systems which enable microphones and electric instruments to be played without cables.

Signal processing gear includes DI boxes, crossovers and a range a of electronic effects, which are typically rackmountable units, including: microphone preamplifiers, electronic vocal processors, exciters, equalizers, compressors and limiters, feedback suppressors and noise gates.

Some stores also sell fog machines, which are used in dances, concerts and theatre productions, often to enhance the appearance of the lighting and laser effects.

These consultants can come to a customer's venue, which may be a nightclub, church, conference center, auditorium or stadium, assess its professional audio needs, and recommend the types of components–speaker enclosures, mixing boards, microphone types, and so on–that would best suit this venue and the customer's budget.
