ContinueMixer Amplifiers — Integrated PA Systems in Tbilisi
Mixer Amplifiers (PA Mixers / Integrated Amplifiers) are integrated audio systems that combine an audio mixer and amplifier in one housing and provide management of multiple audio sources, ideal for stores, schools, restaurants, offices, and any type of small-medium PA system in Tbilisi and throughout Georgia. These amplifiers provide multiple input management (4-12 inputs: microphones, music players, telephone, PC), integrated mixer (volume, bass, treble, priority on each input), built-in amplifier (60W-500W, 100V/70V constant voltage), priority function (microphone automatically reduces music, ideal for voice announcements), zone control (2-6 independent zones, separate volume on each), built-in functions (chime, siren, USB/SD player, FM radio, Bluetooth), and compact design (all-in-one solution, doesn't require separate mixer and amplifier), making them ideal for stores (background music + voice announcements, priority function), schools (classrooms, corridors, voice announcements), restaurants (music + microphone, zone control), offices (background music + voice announcements), hospitals (voice announcements, zone control), and small public buildings (churches, museums, libraries). LAGI offers a complete range of mixer amplifiers: 60W-120W models (4-6 inputs, small stores, cafes), 180W-350W models (6-8 inputs, medium stores, schools), 500W-650W models (8-12 inputs, large stores, shopping malls), multi-zone models (2-6 zones, independent volume), USB/SD/Bluetooth models (built-in music player). All amplifiers are compatible with 100V/70V PA systems.
Main Types of Mixer Amplifiers
- 60W-120W models — low power, 4-6 inputs (2-3 microphones + 2-3 line), 6-15 speakers, ideal for small stores, cafes, offices, classrooms, compact design.
- 180W-350W models — medium power, 6-8 inputs (3-4 microphones + 3-4 line), 20-40 speakers, ideal for medium stores, schools, restaurants, conference halls.
- 500W-650W models — high power, 8-12 inputs (4-6 microphones + 4-6 line), 50-80 speakers, ideal for large stores, shopping malls, hospitals, large schools.
- Multi-zone models — 2-6 independent zones, separate volume control on each zone, ideal for shopping malls, hotels, restaurants where different sound level needed in different zones.
- USB/SD/Bluetooth models — built-in music player (USB flash, SD card, Bluetooth streaming), FM radio, MP3 playback, ideal for stores, restaurants where no separate music source.
- Priority models — automatic priority function (microphone automatically reduces music -10dB/-20dB/-∞dB), chime (bell before voice announcement), ideal for stores, schools where voice announcements frequent.
Frequently Asked Questions
Mixer amplifier — integrated all-in-one solution (mixer + amplifier in one housing), 4-12 inputs (microphones, line inputs), volume/bass/treble control on each input, priority function (microphone reduces music), zone control (2-6 zones), built-in functions (USB/SD player, Bluetooth, FM radio, chime), ideal for small-medium PA systems (stores, schools, restaurants), simple installation (one device), economical (less cost than separate mixer + amplifier). Regular amplifier — only amplifier (no mixer), 1-2 inputs (line level), no volume control on inputs, requires separate mixer or pre-amplifier, ideal for large PA systems, professional installations where separate mixer needed for more control. Recommendation: mixer amplifier — small-medium facilities, all-in-one solution, economy. Regular — large facilities, professional systems.
Priority function (also known as VOX, Voice Over, Auto-Ducking) is an automatic function that reduces background music volume when someone speaks into the microphone. How it works: 1) normal mode — background music plays at normal volume (e.g. 70% volume). 2) microphone activation — when someone speaks into microphone, priority function automatically reduces music volume -10dB/-20dB/-∞dB (complete silence), so voice announcement is clearly audible. 3) microphone deactivation — when speech ends, music automatically returns to normal volume in 2-5 seconds. 4) Chime — some models have chime (bell "ding-dong") that plays before voice announcement so people pay attention. Why important: in stores, schools, hospitals voice announcements are frequent (special offers, evacuation, instructions), priority function ensures these announcements are clearly audible, not lost in background music noise. Recommendation: priority function mandatory for all PA systems where microphones used for voice announcements.
Connecting a mixer amplifier is simple. Steps: 1) input connection — connect audio sources to inputs: microphones (MIC inputs, XLR or 6.3mm jack, phantom power +48V for dynamic/condenser microphones), music player (LINE inputs, RCA or 3.5mm jack, CD player, PC, smartphone), telephone (TEL input, RJ11, automatic priority for phone call). 2) output connection — connect speaker cable (2-core, 1.5mm² or 2.5mm²) from amplifier 100V/70V outputs to speakers (parallel connection, all speakers in parallel). 3) speaker configuration — on each 100V speaker select power (tap selector: 3W/6W/10W), ensure total power doesn't exceed amplifier power. 4) Volume and EQ adjustment — adjust volume, bass, treble on each input, set master volume. 5) Priority configuration — set priority depth (-10dB/-20dB/-∞dB), chime on/off. 6) Zone control — if multi-zone model, adjust volume on each zone. 7) testing — verify all inputs and zones work, test priority function.
