MFA 8000 Bi-Polar Power Amplifier
- MFA-8000 Two Channel Amplifier
-
- The MFA-8000 contains sophisticated power amp monitoring circuits to detect
- abnormal conditions. A highly accurate detector illuminates the true CLIP L.E.D.
- at the onset of clipping. Further increases in signal level will activate a limiter
- circuit to prevent severe overload distortion from occurring, while an illuminated
- LIMIT L.E.D. lets the user know that the function has been activated. Advanced
- thermal management circuitry senses temperature at four different locations in
- the amp and adjusts fan speed accordingly. A THERMAL L.E.D. on each channel
- indicates an above normal operating temperature, while protective circuitry
- automatically attenuates the input signal until the amplifier returns to within a
- normal operating range. The amplifier's output will automatically shut-down in
- the event of a fault condition such as severe overheating, shorted output, DC
- voltage, or ultrahigh frequencies at the output. A PROTECT L.E.D. indicates
- when one or more of these fault conditions occur. As alluded to previously,
- each channel's limiting, thermal, and protection management is completely
- independent of the other channel. Each channel also features a ten-segment
- L.E.D. level meter on the front panel of the amplifier. Standard inputs to the
- amp include balanced XLR (with a transformer available as an option), 1/4" TRS
- connections, and barrier strip terminals with ground lift provision. The MFA-8000
- model is also Ashly PowerCard compatible for other input option possibilities.
- Output connectors include both Speakon and professional five-way binding posts.
