Pré-amplificador/misturador de encastrar INTUSONIC VAA22 12604195

This built-in preamplifier/mixer solves the problem of integrating multiple audio sources into a single, controllable output in installations where space is limited and a flush-mount design is required. It combines two stereo line inputs, a microphone input, and an auxiliary input, giving you flexible mixing with individual volume controls and a master output.

Who is it for

Installers and integrators who need a compact, wall- or panel-mounted audio mixer for commercial or residential applications such as meeting rooms, classrooms, bars, or retail spaces. It suits anyone who needs to blend background music with announcements or paging.
