Q-Series Quad channels Power Amplifiers comprehensive reliability protection measures protect both the amplifier itself and the connected speaker system from damage.
Output Short Circuit Protection: When a short circuit occurs in the external load system (protection threshold less than 1.0 ohm), the digital amplifier will disable power output. Power output will automatically resume immediately after the short circuit is cleared.
Overheat Protection: The amplifier always operates within a defined temperature range. If the ambient temperature exceeds the specified value, the output power will automatically decrease (this operating state is called power compression state), allowing the internal temperature to gradually decrease until it reaches a safe level below 75 degrees Celsius before automatically resetting.
Amplitude Limiting Protection: To prevent signal clipping damage to the speaker system (especially tweeters) when the input signal is too large or contains a large peak level, an automatic amplitude limiting protection circuit is installed. This automatically limits excessively large input peak signals, preventing signal clipping.
Long-Term Output Power Limiting: When a continuous non-musical signal is input for an extended period, the amplifier will automatically attenuate the input signal and limit the output power to prevent damage to the amplifier and speakers.
DC Output Protection: To protect the low-frequency speaker from damage if the output signal contains a large DC voltage.
AC Power Supply Protection: The amplifier will automatically shut down when the power supply voltage exceeds the amplifier's normal operating range.
• High Slew Rate: Slew rate ≥ 40V/μs
• Damping Factor ≥ 600 (100Hz)
• High Power Utilization: Up to 90% utilization, which does not decrease with decreasing load impedance, resulting in low heat generation.
• High Reliability: Traditional analog amplifiers experience temperature rises of 80-100 degrees Celsius under full load, doubling the semiconductor failure rate. Fully digital amplifiers, with their high efficiency, low heat generation, and excellent heat dissipation, offer improved reliability.
• Utilizing new power supply technology, it has low AC power requirements, operating stably between 150-260V, thus adapting to various complex power supply conditions.
• Each amplification channel is independently powered. When all channels operate under high power and heavy load conditions, they will not interfere with each other, nor will they cause overcurrent protection due to excessive instantaneous current. This ensures the consistency of operation for each channel.
• In field applications, the biggest concern with power amplifiers is a single channel failure causing the entire amplifier to shut down. Because the Q-series amplifiers are completely independent amplification modules, each channel is powered independently. This prevents interference between channels. If one channel fails, it can be quickly replaced with another amplification channel without replacing the entire amplifier, adapting to the complexities of touring performances.
