Key Features:

  • High Stable Power Output: These amplifiers are designed to provide consistent power output even in demanding environments, making them an ideal choice for mobile systems and club sound setups.
  • High Efficiency Factor: The SL series amplifiers offer high efficiency, ensuring that more of the power is used for output rather than being lost as heat.
  • Comprehensive Protection Package: Includes overload, short-circuit, thermal, and DC protection to safeguard both the amplifier and connected loudspeakers.
  • Dynamic Limiters: Prevents distortion by limiting the output to safe levels, ensuring that sound quality is preserved even at high volumes.
  • Low-Pass Notch Filter: A unique feature of Dynacord amplifiers that helps to correct frequency response and improve the transient behavior of the connected loudspeakers, optimizing their overall performance.
  • Class AB Output Stage: The amplifier utilizes a Class AB topology for a balance of efficiency and high-quality audio performance.
  • Compact and Lightweight: Despite the powerful output, the amplifier remains relatively lightweight and compact, with a durable design that’s built to withstand tough conditions.

Applications:

  • Mobile Sound Systems: Perfect for touring, event sound reinforcement, and outdoor performances that require stable and high-power output.
  • Club Sound Systems: Ideal for nightclubs, bars, and venues needing reliable and high-quality sound reinforcement.
  • Live Sound Reinforcement: Suitable for use in medium to large events, where consistent power and audio quality are paramount.
  • Public Address (PA) Systems: Effective in conference venues, community events, and theater productions, offering clear, powerful audio reproduction.
