The FBT AX 800 is the entry point to the AX amplifier family — 400W + 400W at 4 Ω or 800W bridged at 8 Ω in a compact 2U chassis. It is the ideal amplifier for small sound reinforcement systems, conference rooms, and distributed audio installations where space and reliability are equally important.
- 800W bridge output (8 Ω) — reliable power for smaller speaker systems
- Class AB topology — low distortion and warm, natural dynamics
- Robust linear power supply with toroidal transformer — clean, stable power delivery
- Damping factor > 400 — precise woofer control
- SNR > 100 dB — silent background for speech and music clarity
- THD < 0.03% — minimal colouration at all operating levels
- XLR / Jack inputs, Speakon / Binding post outputs — professional, flexible connections
- Clip limiter, thermal and short circuit protection — safeguards speakers and the amplifier
- 2U 19" rackmount chassis — neat rack integration
