PA330
30W 100V Mini Amplifier (Class D)
PA330 is a compact 30W amplifier for 100V speakers, with RCA input and volume control. Ideal for remote PA setups and supports relay use with PR7400.
Remote or relay amplifier with a down converter (PR7400)
Accepts unbalanced line input (RCA) with volume control via VC7030
Supports wide input voltage from 110V to 240V AC
Small and space-saving size for easy installation
Introduction
PA330 is a compact 30W amplifier for 100V speakers, ideal for decentralized PA systems in remote or localized areas such as security poles, classrooms, and resort chalets, or to drive high impedance speakers. It accepts unbalanced RCA input with volume control via VC7030, delivering clear and reliable audio.
For extended 100V line systems, it can be used as a remote or relay amplifier with a down converter (PR7400) to drive localized speakers. Built for durability, PA330 maintains stable performance even in higher ambient temperatures.
Packing information
Carton size : 550 (L) x 465 (W) x 180 (H) mm
Gross weight : 16.55 kg
12 unit(s) per carton
