Presentation
The WORK PA 2502 BT is an installation amplifier featuring two independent sound zones, each capable of delivering 250 W of power. It can power both low-impedance 4 Ω loudspeakers and 70 V or 100 V line-loop systems, offering great flexibility for professional installations.
The unit features a mixing section comprising four MIC/LINE inputs with individual gain control, tone controls and a selectable 18 V phantom power supply for use with compatible microphones. Dedicated controls allow the level and sound quality of each connected source to be precisely adjusted.
The PA 2502 BT also features a multimedia interface with a USB MP3 player and Bluetooth connectivity, enabling direct playback of audio content without the need for an additional external source. The built-in echo functions provide further possibilities for applications requiring the use of microphones.
Each zone has its own settings to adapt the sound output to the spaces it covers. A line output allows the mixed signal to be sent to other amplification equipment, whilst a 1 W monitor output can be used to monitor the audio signal.
For applications requiring priority announcements, the PA 2502 BT features a TEL input as well as dedicated priority contacts. Its compact design and wide range of connection options make it suitable for integration into commercial sound systems, public-access premises, professional environments or distributed public address systems.
