EPY-300 digital processing audio power amplifier


● This machine uses a unique high-speed DSP digital floating-point operation technology, built-in adaptive feedback suppression (AFC), background noise reduction (ANC), automatic gain (AGC), power amplifier and other functions in one of the highly integrated voice processing system; ● Adopting adaptive environmental howling suppression algorithm, high-speed floating-point digital audio processor and advanced sub-band (Sub-Band) echo cancellation (Echo Cancellation) technology, howling and echo can be completely eliminated at high speed and fully automatic, while on-site audio can be sent out accurately, clearly and in real time, and can be switched through "feedback/through;

    This machine uses a unique high-speedDSP digital floating-point operation technology, built-in adaptive feedback suppression (AFC), background noise reduction (ANC), automatic gain (AGC), power amplifier and other functions in one of the highly integrated voice processing system;

    Adopts an adaptive ambient howling suppression algorithm, a high-speed floating-point digital audio processor and an advanced sub-band (Sub-Band) echo cancellation(Echo Cancellation)Technology, can be high-speed automatic completely eliminate howling and echo, while allowing live audio accurate and clear real-time transmission, can pass "feedback/Through switching;

    Built-in automatic pressure limiter, throughCOMPRESS adjusting the total output level, when multiple microphones are used at the same time, it can prevent the feedback caused by the increase of the gain of the whole system;

    Built-in adaptive dynamic noise filter, which can filter out the background noise of the field environment without affecting the high-quality transmission of the voice signal;

    The built-in system intelligent level control technology can obtain a clear, continuous voice signal with no obvious fluctuation in signal level,AGC two-way control, with the ability to distinguish between strong signals and soft signals;

    Microphone high, low-pass filter,10-segment diagram equalizer, auxiliary adjustment tone and feedback howling point;

    Built-in automatic mixing function, microphone intelligent four choose one;

    The local four-channel microphone input (48V phantom power supply), two sets of stereo line inputs, one set of stereo line outputs, one set of auxiliary recording outputs,A,Bgroup power output, reserved digital,2.0USBInput interface;

    Keyboard lock function: when the administrator has finished debugging the equipment, the panel button is locked to prevent non-administrators from operating;

    Through the machineUSB connection to computerPCinterface settings, support232Central control regulation;

    Adapt to teaching, conference, speech, trial, recording and other language sound reinforcement system.
