Product description
Detailed parameters
● This machine adopts unique high-speed DSP digital floating-point computing technology, built-in adaptive feedback suppression (AFC), background noise reduction (ANC), automatic gain (AGC), power amplifier and other functions in one integrated high-intelligence speech processing system;
● Adaptive environment howling suppression algorithm, high-speed floating-point digital audio processor and advanced sub-Band echo cancellation (Echo Cancellation) technology, can automatically eliminate whistle and echo at high speed and fully enable live audio Accurate and clear real-time delivery, you can switch through "feedback / pass-through";
● Built-in automatic pressure limiter, adjust the total output level through COMPRESS, when the multi-microphone is used at the same time, it can prevent the feedback due to the increase of the gain of the whole system;
● Built-in adaptive dynamic noise filter can filter out the background noise of the scene environment without affecting the high quality transmission of voice signals;
● Built-in system intelligent level control technology, can obtain clear, continuous voice signal with no obvious fluctuation of signal level, AGC bidirectional control, with the ability to distinguish between enhanced signal and soft signal;
● Microphone high and low pass filters, 10-band graphic equalizer, auxiliary adjustment tone and feedback howling point;
● Built-in automatic mixing function, four choices of microphone smart;
● This machine has four channels of microphone input (48V phantom power), two sets of stereo line input, one set of stereo line output, one set of auxiliary recording output, A and B group power output, reserved digital, 2.0USB input interface;
● Keyboard lock function: When the administrator debugs the device, the panel keys are locked to prevent non-administrators from operating;
● It can be connected to the computer PC interface through the USB of this machine, and supports 232 central control adjustment;
● Adapted to language, sound reinforcement systems such as teaching, conference, speech, trial, recording and broadcasting.
