Deaf Bonce MACHETE MFA-2.80 | 80 Watt 2-channel amplifier

Deaf Bonce MACHETE MFA-2.80 is a compact 2-channel Class D amplifier designed for high-current car audio installs, delivering 120 W x 2 at 2 Ω and 240 W x 1 in bridge mode at 4 Ω. Its 7.1 x 6 x 2.2 inch chassis packs substantial power with precise crossover control.

• Class: D — efficient switching topology that preserves power headroom in a small form factor.
• 2-channel power output (2 Ω): 120 W x 2 — strong performance with low impedance drivers, allowing higher dynamic range and better control of hard-to-drive speakers.
• 2-channel power output (4 Ω): 80 W x 2 — suitable for standard 4 Ω speakers with solid headroom and warmth.
• Bridge power (4 Ω): 240 W x 1 — mono mode for a single high-power woofer or sub, simplifying low-frequency tasks.
• Frequency response: 20–20000 Hz — covers the full audible range for typical car audio installations.
• Minimum load: 2 Ω per channel; 4 Ω in bridge — defines stable operation boundaries for individual channels and bridged configurations.
• Input sensitivity: 0.4–8 V — accommodates a wide range of head units and source levels for clean level matching.
• Low pass / High pass filters: 50–12000 Hz (LPF and HPF); LPF and HPF simultaneous operation — flexible crossovers to shape speaker bandwidth and reduce overlap between drivers.
• Crossover slope: 12 dB/Oct — moderate steepness to separate bands without excessive phase shift.
• Input terminal: 4 Ga; Output terminal: 10 Ga — supports high-current wiring for stable delivery to low impedance loads.
• Working voltage: 9–15 V — compatible with typical automotive electrical conditions and voltage fluctuations.
• Signal-to-noise ratio: ~90 dB — low noise floor for clearer signal at higher SPL levels.
• Size (WxLxH): 7.1 x 6 x 2.2 inch — compact footprint suitable for tight installation spaces.

In a two-channel setup or bridged mono application, MFA-2.80 provides solid, controllable power with flexible crossover options to tailor bass and mid/high bands, while maintaining efficiency and low noise in a compact chassis.
