Model: DSP-200
A: functional feature
⊙.Built-in 24Bit A/D, D/A conversion; 24bit DSP processor, 48KHz high-speed sampling, using high-speed floating-point operation.
⊙Adopt adaptive environmental whistle suppression algorithm (AFC) sound transmission gain improvement: ≥10dB, using high-speed floating-point digital audio processor and advanced sub-band noise reduction and elimination technology, can quickly and automatically completely eliminate whistling and background noise ( ANC). The signal-to-noise ratio is improved by 15dB.
⊙System intelligence (AGC) two-way level control technology, can obtain clear, continuous output without obvious fluctuation of voice level. Gain control range: -9dB - +9dB.
⊙Built-in digital compressor: It can protect the loudspeaker from being damaged by sudden loud pressure.
⊙Digital noise gate: Multi-level threshold adjustment can remove unwanted sound.
⊙10-segment digital equalization: You can adjust and compensate the tone.
⊙With parameter locking function: One-key locking of debugged parameters. It can avoid parameter misoperation
⊙The function can be adjusted through the computer PC interface to support the central control. The PC interface can be set friendly to administrator mode and normal user mode.
⊙6-way microphone input (3+1(gooseneck)+1(handheld)+1(2.4G)), independent adjustment and sensitivity adjustment. Can be customized
⊙Each MIC is powered by an independent 48V phantom power supply, which can be switched independently.
⊙ Comes with 8 Euro 2*150W digital power amplifier. Small size (1U chassis) and light weight 4.5KG
⊙Switching power supply with wide voltage input 170-250V input.
⊙Built-in USB recording interface, you can directly insert the U disk to record and support various audio formats
⊙ Optional remote conference output (with echo cancellation ANC)
⊙ Optional external yd mute switch panel can be placed on the podium, which is convenient for teachers to operate in class. It can adjust the volume by ±2-3dB and has an indicator light to display the decibel number. It also has a mute function, and it does not affect the recording effect when it is muted.
B: Applicable places: conference rooms, courts, multimedia classrooms, etc.
