Class AB sound quality
Class D amplifier efficiency
Top for professional audio amplifier
About VPL(Voltage Peak limit)
VPL technology allows the amplifier to work in its hardware can be allowed within the safe range., at the same time, even in the case of amplifier facing clipping is also able to ensure a smooth and well-controlled output. VPL power management allows a single amplifier can work on different occasions. VPL power management allows the same amplifier can work on different occasions.
About protection
Incorporates comprehensive warning and protection features to safeguard the amplifier and all connected loudspeaker drivers. Front-panel indicators and the Device Control GUI give warnings when any potential problems are detected. Protection measures are enabled only when critical thresholds are passed; Measurements are re-checked every few seconds, and normal operation resumes automatically when nominal conditions are restored. The complete protection/warning suite includes: DC at output, short circuit, excessive output current, sustained very high frequency(VHF), and open load.
Configurable for any signal, any load
Adopts FTD class amplifier technology. Offers eight-position input gain switch to optimize performance with any input signal. Ln addition, each channel incorporates our exclusive Voltage Peak Limiter (VPL) circuit. VPL precisely tailors output for any type of load, from a single massive 2-ohms subwoofer to a series of 16-ohm MID or high-frequency drivers. Working in concert, adjustable input gain and VPL optimize each channel for maximum headroom regardledss of input signal dynamics or load impedances.
About amplifier cooling system
Either power supply or output stage, with FTD class technology, power amplifier is ultra-efficient.
With thousands of tiny copper cooling fins. Copper has better thermal performance than aluminum; Thousands of small cooling fins greatly increase the contact area with the cooling airflow. All of the output components are perpendicular to the cooling airflow. Twin variable-speed fans allow air into a pressure chamber, followed by the same time every component and heat cooling fins, uniform heat dissipation, more effectively cooling ensures the reliability of the prolonged use.
In the Amplifier field, we normally know the audio amplifier category of class AB, class H, class D, and so on, which is the key of audio amplifier for high-quality audio. Professional audio technology-based power amplifier using Class D amplifier technology (pulse width modulation) to promote class AB output stage; This technology not only protects the integrity of the Class AB sound quality, and also shows its efficiency, energy-saving characteristics. Now we named it to be FTD class amplification type. With the adove technical advantages, the FTD class core technology will become the new classic in the field of audio amplifier.
