With its unique characteristics the FM 711-MKIII will be uncontested for many, many years to come

• Music reproduction to dream of...
   
• Prodigious Power to drive the most demanding loads
   
• Proprietary discrete circuitry using special curve-tracer analysed and hand selected semiconductors
   
• Superb balanced discrete Class A input stage. Sensors automatically recognize the connection standard and perfectly balance both unbalanced and pseudo-balanced signals sources right at input
   
• Tremendous headroom and reserves
   
• Perfect signal symmetry
   
• Superb rejection of noise, hum or interference thanks to perfectly balanced inputs (interference rejection is 100-1000 times better than other so-called "balanced" equipment)
   
• Multi-protection systems for amplifier and speakers trigger the output and reset automatically when the error disappears.
   
• No signal compression, limiting nor any other negative influence on the audio signal is possible. The protection circuits are totally separate from all audio stages.
   
• Outputs drive any speaker load perfectly, even very low impedance - or high highly capacitive - transducers
   
• Unique dynamic damping of speakers results in phenomenal impulse response accuracy and no ringing
   
• Proprietary enhanced Class A circuitry provide unmatched musicality
   
• Grand Prix-winning circuit technology guarantees total absence of any form of distortion - be it dynamic or static and even at the lowest signal levels - it betters other designs by a magnitude.
   
• Precision low noise level controls avoid the often experienced change in tonal characteristics when changing the level
   
• Ultra low-loss FORCEPLUG 200 output connectors.
   
• Tremendous output current capability as peak output current is not limited
   
• 5000 V mains spike suppressors
   
• Mechanical resonance elimination with the new MKIII isolation supports
   
• Lowest impedance power supply for unlimited rendering of dynamics
   
• The internal transformer is completely shielded from audio circuitry; special shielding techniques prevent stray fields
   
• Hand-selected and perfectly matched components of DIN, IEC & MIL standard
   
• Each unit is hand crafted and calibrated in Switzerland to absolute performance standards
   
• New high reliability components help to further increase lifetime expectancy

Input:
Proprietary, electronically balanced, discrete enhanced class A circuitry, floating ground, non- inverting or inverting mode.
Optimal performance with either balanced or single ended (unbalanced) sources.
Unbalanced sources are automatically balanced right at the input of the FM 711-MKIII.

Input Sensitivity:
1,6 V RMS for full output

Input Impedance:
At all level settings from balanced and unbalanced sources: 40 kOhm

Chassis Resonance Damping:
New chassis design effectively isolates sensitive electronic and mechanical components from potential negative influences such as induced resonances. Specific purpose-designed anti-resonance technology is employed.

Load Impedance:
No minimum impedance. The amplifier is designed for 1 Ohm to 10'000 Ohm systems. It can drive any speaker impedance (even below 1 Ohm) with dynamic (music) signals without any limiting, compression or other negative effects on the audio signal.
Despite this, the amplifier is fully protected against short circuits, open circuits and all other adverse conditions via unique on- board safeguarding circuits that continuously survey all important parameters.

11/10: New - Factory Sealed Shipment Items classified as "NEW" must be in a factory-sealed box. Sellers must specify any manufacturer warranty included. Some manufacturers honor warranties only if purchased from an authorized dealer, while others limit warranties to the original owner, even if the item remains unopened. Any "NEW" listing should include a warranty statement. If absent, buyers should confirm details with the seller. Assumptions should be limited to the item being factory sealed.

Items opened for inspection or any other reason should not be rated as "New."

10/10: Mint - Like New, Unused Appearance "Mint" signifies an item that looks factory fresh. To qualify:

• Removed from original packaging, no more than a year since first use, and manufactured within the last five years.
• Electronics must be free from scratches, blemishes, discoloration, and connector wear.
• Speaker grilles should have no pulls or discoloration; speaker bottoms should not show floor wear.
• Turntables must appear unused with pristine covers free from swirls, dust, or fingerprints.
• Pre-owned and demo items rarely meet this standard. A thorough inspection is recommended.

9/10: Excellent - Nearly Perfect, Minimal Use

• Typically one-owner or store-demo items.
• Electronics should look factory fresh, with only minor dust in crevices.
• Connector plating may show slight signs of use but without discoloration.
• Speakers should be flawless except for minor stand-mounting marks on the back or bottom.
• Wood finishes must not exhibit sun fading or uneven discoloration.
