The FFA series of audio power amplifiers are high fidelity, high power output professional power amplifiers. FFA amplifiers are ideally
suited for a variety of professional audio applications. We have thoroughly tested our products during the design phase and once we
are satisfied that the design criteria has achieved we undertake extensive real world field trials to further prove the design. After the
manufacturing process each amplifier is subjected to a series of test procedures including a high power ‘burn in’ or ‘soak ‘period
where the amplifier is driven into its specified minimum rated load.
FFA amplier series features:
Amplifier overview
• FFA specialise in designing power ecient Class D ampliers and high capacity switching power supplies.
• Innovative cooling systems for long term reliable performance –excellent thermal capacity for use in high temperature environments.
• Rugged chassis designs to ensure the electronic systems are protected.
• Exceptional audio sound quality, proven superb bass drive even when driving the toughest loads.
• 5 year no quibble manufacturers warranty.
• ‘Soft start’/ full in-rush protection, amplier clip limiter. DC shutdown, low mains voltage.
• Industry standard quality input/ output/mains connectors all manufactured by Neutrik.
• Designed and made entirely by FFA in Hertfordshire, England.

The amplifier is built around the industry standard 2 RU (88mm) high and 19” wide rack space. The amplifier requires a depth of 500mm
from rack ear fixing points to rear of unit. Rear rack ear brackets are built in as standard, please use these to provide maximum protection
for your investment. Any damage caused by insufficient support will not be covered by warranty. Allow 40mm clearance for amplifier
front panel handles. Always use nylon type washers with standard M6 type rack fixing bolts to protect the anodised front panel.
Once installed in a rack care should be taken not to obstruct the air intake vents on the rear of the unit and air exhaust located centre of
front panel. Obstructing airflow may cause the amplifier to trigger ‘temperature protection’ prematurely. The amplifier has one high CFM
fan which is designed to pull cool air from the rear of the unit and blow hot air out of the front of the unit. The fan must only be used in
this direction due to the high pressure cooling chamber in front of the fan. The fan is two ‘speed’ which is dependant on temperature
within the unit.
IMPORTANT: The amplifier should not be sited directly near smoke or fog generating machines as glycol based smoke fluids are highly
corrosive and will cause irreparable damage within the amplifier and will void its warranty.
The amplifier should not be exposed to rain or moisture either during storage or use. If the unit become wet isolate from electricity
supply immediately and leave in a warm dry place to dry out. Should the amplifiers be transported from a cold location, for example a
vehicle outside and taken into a warm venue condensation could occur inside the unit. Always allow time for the unit to acclimatise
before powering the unit up.
