迷你三输入音频放大器带麦克风混音器

Routes audio from any combination of analog or digital sources through a single 40-watt amplifier output switchable between 70V and 100V distributed speaker systems — with built-in MIC mixing, ducking, Bass/Treble EQ, and 48V phantom power in a compact desktop chassis. Three switchable inputs (dual-mono RCA, 3.5mm stereo, and TOSLINK optical) handle the full range of source types found in installed AV environments.

Designed for classrooms, conference rooms, lecture halls, restaurants, and hospitality spaces, the AP3DBL supports RS232 serial control with 16 addressable ID codes for multi-unit installations, IR remote control, and front panel operation. MIC input accepts condenser, dynamic, and wireless microphone types with balanced/unbalanced signal support and automatically ducks line audio when MIC signal is detected.
