F-3000 intelligent high-speed feedback suppressor


● This machine adopts high-speed floating-point digital audio processor and advanced sub-band (Sub-Band) echo cancellation (Echo Cancellation) technology, which can completely eliminate howling and echo at high speed and fully automatic, and at the same time make the live audio accurately and clearly sent out in real time. It can be switched through "FSC/BYPASS; ● Built-in feedback suppression function, adaptive environment howling suppression algorithm, built-in 24Bit A/D, D/A conversion; 24-bit DSP processor, 48KHz high-speed sampling; ● 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, can be obtained to clear, continuous, no significant fluctuations in the signal level of the voice signal; ● Built-in AGC two-way control, with the ability to distinguish between enhanced signals and soft signals; ● Built-in 10-segment diagram equalizer to assist in adjusting timbre and feedback howling point; The machine has high, bass adjustment and gain adjustment function; The machine set 2 channels of music input, 8 microphone input; ● 2X16 blue LCD screen display, adjust the parameters at a glance; ● Microphone 1-4 automatic four choose one function; ● Unique wireless microphone dedicated input interface; ● Built-in 48V phantom power supply, (microphone 1~4, 5~8 each a switch); ● Unique microphone recording output switch, no music output when the switch is OFF; The machine with balanced output and a set of auxiliary recording output; ● Keyboard lock function; ● Can be connected to the computer through the local USB PC interface settings using 2 modes (administrator, user) for easy management. Support 232 central control adjustment; Adapt to the teaching, conference, speech, trial, recording and other language sound reinforcement system.
