Small PA systems for venues such as bars and clubs are now available with features that were formerly only available on professional-level equipment, such as digital reverb effects, graphic equalizers, and, in some models, feedback prevention circuits which electronically sense and prevent audio feedback when it becomes a problem.
PA system set-up Venue size Small system: 2 pole-mounted mid/high frequency PA speaker cabinets and 2 small subwoofer cabinets with 15" or 18" subwoofers (this would be used in club where jazz, acoustic music, country music or soft rock is played) Small club with capacity for up to 300 people
In some small to mid-size venues, such as bars and nightclubs, the PA system may not have the capacity to provide the bass sound for the venue, and the PA system may be used mainly for vocals. Bass players in bands that play at a variety of venues, including these types of small to mid-size venues, may need to be able to provide the bass sound ...
A line array is a loudspeaker system that is made up of a number of usually identical loudspeaker elements mounted in a line and fed in phase, to create a near-line source of sound. The distance between adjacent drivers is close enough that they constructively interfere with each other to send sound waves farther than traditional horn-loaded ...
A coffeehouse or small bar where singers perform while accompanying themselves on acoustic guitar may have a relatively small, low-powered PA system, such as a pair of two 200 watt powered speakers. A large club may use several power amplifiers to provide 1000 to 2000 watts of power to the main speakers.

Markup price = (unit cost * markup percentage) Markup price = $450 * 0.12 Markup price = $54 Sales Price = unit cost + markup price. Sales Price= $450 + $54 Sales Price = $504 Ultimately, the $54 markup price is the shop's margin of profit. Cost-plus pricing is common and there are many examples where the margin is transparent to buyers. [4]
Acoustic impedance, denoted Z and measured in Pa·m −3 ·s in SI units, is defined by [2] = ^ ^ (), where ^ is the Laplace transform of sound pressure, [citation needed] ^ is the Laplace transform of sound volume flow rate.
