Professional Power Amplifiers for Stage & Live Sound

Q: What's the difference between Class D and Class AB amplifiers?

Class AB — traditional technology, high sound quality, but low efficiency (60-70%), heavy weight. Class D — modern technology, high efficiency (>90%), light weight, low heating.

Q: How does Bridge mode work in professional amplifier?

Bridge mode allows combining two channels into one mono channel with double power — normal mode: 2 channels × 1000W, Bridge mode: 1 channel × 2000W.

Q: Can professional amplifier be remotely controlled?

Yes, modern professional amplifiers support remote control — Ethernet connection, RS-485 connection, Dante/AES67. Remote control functions: volume level adjustment, DSP parameters, monitoring.

Professional Amplifiers — For Concerts and Events in Tbilisi

Professional Power Amplifiers are high-power audio devices that provide powerful and highest quality sound for concerts, clubs, theaters, festivals, and large events in Tbilisi and throughout Georgia. These amplifiers are ideal for professional audio systems requiring high power (1000W-10000W), low distortion (THD <0.1%), high signal-to-noise ratio (SNR >100dB), and stable 24/7 operation. LAGI offers professional amplifiers with full functionality: Class D/Class AB topology, 1000W-10000W power (2Ω-8Ω load), 2-4 channel models, XLR/Speakon input/output, DSP processor (equalizer, Limiter, Crossover), Bridge/Parallel mode, fan cooling, protection from overload/short circuit/overheating, LCD screen (power, temperature), Ethernet/RS-485 control. All models comply with CE standard.

Main Functions of Professional Amplifiers

High power — 1000W-10000W, ideal for large halls, concerts, festivals.
Class D topology — high efficiency (>90%), low power consumption, light weight.
DSP processor — built-in equalizer, Limiter (speaker protection), Crossover (frequency separation).
Bridge mode — combining two channels into one mono channel (double power).
Protection — overload, short circuit, overheating, DC protection.
Ethernet/RS-485 — remote control, monitoring, parameter configuration.

FAQ — Frequently Asked Questions

What's the difference between Class D and Class AB amplifiers?

Class AB amplifiers — traditional technology, analog amplification, high sound quality (THD <0.01%), but low efficiency (60-70%), heavy weight (20-40kg), strong heating (requires large heatsink). Class D amplifiers — modern technology, digital amplification (PWM), high efficiency (>90%), light weight (5-15kg), low heating, but slightly higher distortion (THD <0.1%). Recommendation: Class D — modern choice (light, efficient, cheap), Class AB — for audiophiles (highest quality).

How does Bridge mode work in professional amplifier?

Bridge mode (also known as Bridged Mono, BTL) allows combining two channels into one mono channel with double power — normal mode: 2 channels × 1000W = 2000W (stereo), Bridge mode: 1 channel × 2000W = 2000W (mono). Application: large subwoofers (require high power), large halls (one powerful channel), mono PA systems. Connection: channel 1 + → speaker +, channel 2 + → speaker -, on amplifier enable Bridge mode (usually button or DIP Switch). Warning: in Bridge mode speaker impedance must be double (if normally 4Ω → in Bridge mode 8Ω).

Can professional amplifier be remotely controlled?

Yes, modern professional amplifiers support remote control — Ethernet connection (control in local network or via internet, Web interface, PC/Mac/iOS/Android app), RS-485 connection (simultaneous control of multiple amplifiers with one cable, distance 1200m), Dante/AES67 (digital audio network). Remote control functions: volume level adjustment (Gain), DSP parameters (equalizer, Limiter, Crossover), Bridge/Parallel mode enable, monitoring (power, temperature, load), Firmware update. This is ideal for large facilities — centralized control for all amplifiers.
