Audison Forza AF M1.7 bit Mono Subwoofer DSP Amplifier - 1200W RMS at 1Ω

The Audison Forza AF M1.7 bit is a Class D mono subwoofer dsp amplifier designed for controlled, powerful bass. Its continuous RMS output is 1 × 600W at 4Ω, 1 × 1000W at 2Ω, or 1 × 1200W at 1Ω.

Built-in 7-channel digital signal processing combines one amplified subwoofer channel with additional processed outputs for system expansion. Native 24-bit/96kHz processing and bit Drive tuning provide control over equalisation, crossover settings and time alignment, helping an installer integrate the system and tailor its sound to the vehicle.

Bass-Magnifier processing and dynamic loudness provide dedicated subwoofer tuning. Eight native input channels, optional F4IN expansion, an optical digital input and compatibility with optional B-CON and DRC controllers allow the system to grow around your installation.

Power figures are continuous RMS at 14.4V DC and 1% THD. The 1200W rating applies at a 1Ω load. Optional accessories are sold separately.
