ContinuePre Amplifiers — For Public Address Systems in Tbilisi
Pre Amplifiers are professional audio devices that collect, process, and prepare audio signal for Power Amplifier in Public Address (PA) systems in Tbilisi and throughout Georgia. These devices are ideal for shopping centers, hotels, offices, schools, hospitals, and any large facility requiring complex sound system — pre amplifier combines multiple audio sources (microphones, music, announcements), processes signal (equalizer, tone control, volume level), and distributes to different zones. LAGI offers pre amplifiers with full functionality: 4-8 input channels (microphone, Line, AUX), 2-6 output zones, built-in mixer, 3-band equalizer (Bass/Mid/Treble), tone generator (Chime), Priority function (urgent announcements), Phantom Power 48V (for condenser microphones), VOX function (voice activation), RS-485/Ethernet control, 100V Line output. All models comply with CE standard.
Main Functions of Pre Amplifiers
- Multiple inputs — 4-8 channels (microphone, Line, AUX), simultaneous connection of multiple sources.
- Zone outputs — 2-6 zones, different audio in different zones (e.g. zone 1: music, zone 2: announcements).
- Built-in mixer — volume level adjustment for each channel, balance, panorama.
- Equalizer — 3-band (Bass/Mid/Treble), sound quality improvement.
- Priority function — during urgent announcement automatically dims music, restores after announcement.
- Phantom Power 48V — power for condenser microphones.
FAQ — Frequently Asked Questions
Pre Amplifier — collects and processes audio signal, doesn't provide power to speakers. Functions: multiple inputs (microphone, Line, AUX), mixer (volume level adjustment), equalizer (Bass/Mid/Treble), zone outputs, Priority function. Power Amplifier — receives signal from pre amplifier and provides power to speakers (50W, 100W, 250W). Typical PA system: audio sources → pre amplifier (processing) → power amplifier (power) → speakers.
Priority function (also known as Ducking, Mute, Override) allows making urgent announcements with background music dimming — set Priority input (usually Mic 1), when signal appears on this input (announcement) → automatically dims all other inputs (music, AUX) → announcement heard maximally → after announcement ends (2-5 seconds) → music automatically restores. This is ideal for shopping centers, hotels, airports — background music constantly plays, automatically dims during announcement.
Yes, modern pre amplifiers support remote control — RS-485 connection (simultaneous control of multiple devices with one cable, distance 1200m), Ethernet/IP connection (control in local network or via internet, Web interface), IR Remote (infrared remote, distance 10m). Remote control functions: volume level adjustment (Master Volume, Zone Volume), input selection (Mic/Line/AUX), equalizer parameters, Priority on/off, zone on/off. This is ideal for large facilities — centralized control for all zones.
