MF Series are the most advanced and best sounding power amplifiers that ALTAIR has ever created, but what makes them so special?

The answer is very simple: All MF Series amplifiers incorporate MOS-FET technology power transistors with LATERAL geometry. These devices ensure an outstanding reliability, ever-lasting operation and the highest sound quality. Great sounding power amps that (almost) last forever. MF Series also allow 2Ω operation.

• MF-8: 2 x 400W (4Ω)
• MF-12: 2 x 600W (4Ω)
• MF-16: 2 x 800W (4Ω)
• MF-24: 2 x 1200W (4Ω)

These power amplifiers offer exceptional quality and efficiency, incorporating important improvements such as new clipping circuit limiters, multiple protection systems including solid-state relays, monoblock chasis, high damping factor and total interconnection flexibihity.

FEATURES

• PROTECTION: against on/off switch transients, electronic protection against short-circuit and open circuit, against overheating in output transistors and power supply, against DC  by solid-state relay.
• SPEAKON Besides a 4mm diameter twin binding per channel (normahized according to EN-60065), MF power amps incorporate SPEAKON connectors.
• BALANCED Electronically balanced input circuits for noise immunity in long wiring set-ups.
• MF Series power amplifiers are prepared to work in low impedance conditions,down to 2 Ω loads.
• COOLING Heat evacuation guaranteed by temperature dependent high flow fan operation (front to back servo assisted fan circuits).
• POLARITY An inboard switch is included, in order to select the input polarity.Although the A.E.S. organization recommends 2+ nonn, al present time, an important percentage of sound equipment is wired with 3+ polarity.
• H CLASS The MF 24 (highest power of the series), incorporales H class configuration output stages for improved amplifier and power supply efficiency, offering as a result an increase in power and a reduction in weight.
• SENSITIVITY Through intemal adjustments on the input module board, several input sensitivities can be selected, in order to adapt the amp to the rest of the equipment.
