FEATURES


Features:

  • Class D Technology: This amplifier uses Class D technology, which employs high-speed switching to amplify audio signals with high efficiency. It generates less heat and is more compact than traditional amplifiers, making it ideal for high-power audio systems.
  • Direct Connect Speaker Terminals: These are robust, secure terminals that allow speaker wires to connect directly to the amplifier without additional connectors. This design reduces signal loss and ensures a solid, low-resistance connection for better audio performance.
  • Large Gauge Power Wire Inputs: The amplifier can accept thick, high-capacity power cables (lower AWG numbers). This allows more electrical current to flow into the amplifier, reducing voltage drops and ensuring stable, reliable performance, especially at high power levels.
  • Selectable Low Level RCA Input Range: This feature allows users to adjust the sensitivity of the RCA inputs to match different source unit output levels. It ensures compatibility with a wide variety of head units and processors, helping optimize signal input levels for clean, distortion-free audio.
  • PWM Mosfet Regulated Power Supply: A Pulse Width Modulated (PWM) Mosfet power supply provides consistent, efficient, and stable power to the amplifier’s internal components. It ensures the amplifier operates reliably even under heavy loads, minimizing the risk of power fluctuations or distortion.
  • APC - Audio Protection Circuit: This built-in protection system monitors the amplifier’s operation and safeguards it against potential issues like short circuits, overheating, and overloads. If a problem is detected, the circuit limits or cuts off output to prevent damage to the amp and connected speakers.
  • SESI - Signal Evaluation Status Indicator: A visual status indicator that shows the amplifier’s operational state. It alerts users to signal problems such as clipping, overload, or abnormal input levels, helping maintain system performance and prevent damage.
  • CHM - Collective Heat Management: An integrated heat management system that includes features like heatsinks, venting, and thermal protection circuits to keep the amplifier operating at safe temperatures, even during extended high-volume use.
  • 2-Ohms Stereo / 4-Ohms Bridged Capability: This amplifier can be configured to run two speakers at 2 ohms each in stereo mode, or it can be bridged to power a single speaker at 4 ohms. This offers flexibility for different audio system setups and power requirements.
