F-Series power amplifiers are designed to live sound reinforcement, touring systems or fixed installation. As toroidal power transformer power amplifiers, they are top standard quality in current market. They are the ideal choice when high headroom and low distortion are needed, especially when reproducing the dynamic range and clarity of today digital recordings.
Key Feature:
Key Feature:
• 2/3U high, heavy duty steel chassis
• Modular construction for easy servicing
• Symmetrical layout for even weight distribution
• High efficiency toroidal power transformer
• Oversized, high energy, linear power supply
