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; ● Built-in automatic pressure limiter, through the COMPRESS adjustment of the total output level, in the use of multiple microphones at the same time, can prevent the overall system gain rise, and the resulting feedback; ● 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; ● Built-in system intelligent level control technology can obtain clear, continuous voice signals with no obvious fluctuation in signal level. AGC two-way control has the ability to distinguish between enhanced 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 machine has four microphone inputs (48V phantom power supply), two groups of stereo line inputs, one group of stereo line outputs, one group of auxiliary recording outputs, A and B groups of power outputs, with reserved numbers and 2.0USB input interfaces; ● Keyboard locking function: when the administrator has finished debugging the equipment, the panel button is locked to prevent non-administrators from operating; ● Through the local USB connection computer PC interface settings, support 232 control adjustment; Adapt to the teaching, conference, speech, trial, recording and other language sound reinforcement system.
