Perfect reliability Protection measures:
The DP Series power amplifiers have excellent reliability protection that protects the power amplifier from damage in the event of a misuse and protects the speaker system connected to it.Soft Start, DC, Secondary Audio, HF, Overheating, Short Circuit, Power On / Off Mute;
Soft-start: Non-contact soft-start circuit can effectively inhibit the switching power supply to the grid when starting the impact of the surge.
DC protection: If the output signal with a larger DC voltage, in order to protect the woofer from
damage, the machine has a limited DC output protection;
Secondary audio protection: If the output signal with a substantial second audio signal,
in order to protect the woofer from damage, sub-audio protection circuit will be protected;
High-frequency protection: long-term input signal above 10kHz, in order to prevent damage to the amplifier and tweeter, the
amplifier will automatically attenuate the input signal, limiting the output power.
Overheat protection: the amplifier to work in a limited temperature range, if the amplifier internal
radiator temperature exceeds 85 ℃, the output power will be automatically reduced (the working
condition at this time known as power compression), the temperature inside the machine graduallydecreased. If the power after the compression temperature can not fall below 95 ℃, the amplifier
will stop running until the temperature inside the machine down to 75 ℃ below the temperature
will automatically reset operation.
Short circuit protection: amplifier external load system short circuit (protection threshold is less
than 1.0 ohms), the power amplifier to prohibit the output. After short circuit troubleshooting, the power output is automatically restored immediately.
Power on / off mute: Power amplifier will instantly mute the power switch, so you can effectively
avoid the power amplifier to switch the speaker to the abnormal impact
