PA: Features:
In an audio system, peripheral equipment and sidelines are complex and have a wide range of equipment, including compressors to make sounds strong, enhancer boosters, sound quality equalizers, filter or enhance certain Parameter equalizer for signal, feedback suppressor for whistling sound, limiter for protecting speaker unit, delay device for adjusting horn time difference, equalizer for compensating room frequency response defect... so many equipment, engineering Businesses are getting dizzy, not to mention the average user. The less experienced users, seeing the stars like the stars in the sky, the control buttons, the inexhaustible connecting lines, really can't start, it is daunting.
DriveRackTMPA's design engineers understand the needs of the user and design a new generation of peripherals that combine all of these features. From now on, there is only one device from the mixer to the amplifier, a controller that includes all the basic peripheral functions. not only,
The DriveRackTM PA is designed to take care of the convenience of the contractor and incorporates the technical parameters of most JBL speakers and Crowm amplifiers. The engineer only needs to follow the instructions of the Setup Wizard to sequentially select and input the model and working status of the device. The rest of the tedious work is automatically done by DriveRackTMPA.
Connected to the RTA-M standard test microphone and Auto-EQ auto-balance function, DriveRackTMPA automatically adjusts the room balance to compensate for frequency noise defects caused by poor built-in sound. The fast-tracking feedback suppressor combined with precise output limiting protection is a boon to users and engineers, ensuring stable system operation.
