2231 EQ Dual 31-Band Professional Audio Equalizer for Stage Performance/Audio Speaker/Home Meeting

Description:
- Type III noise reducer: The design of the new Type III noise reducer eliminates the helpless phenomenon of both signal and foreground noise increasing simultaneously during gain.
- Adding limiter: A limiter has been added to the design to protect the speaker from overload or special sound effects.
- Unique 102dB signal-to-noise ratio: The EQ series equalizer has a signal-to-noise ratio of up to 102dB, which is a big surprise for improving the overall performance of the audio system.
- The equalizer of the new era: The new concept of Type III noise reducer and limiter has opened up a new era of equalization for the EQ series equalizer.

Features:
- Switchable ±6dB or ±12dB boost/buck range
- Front panel bypass switch
- 4-stage LED cascade display for monitoring output level
- Signal dynamic range greater than 108dB
- 12dB per octave, 40Hz low-end cut-off filter
- ±12dB input gain adjustment range
- XLR and TRS input/output connectors
- Frequency response from 10Hz to 50kHz

31 segment 1/3 octave band graphic equalizer:
- The gain/attenuation values can be selected as +/-6DB or +/-15DB. The input gain control is a 41-level stepper rotary potentiometer with EQ selection key, which can bypass the 40Hz low-frequency cut-off filter of EQ and is very useful for live performances.

Noise free gain EQ:
- The function of the graphic equalizer is to gain or attenuate a certain frequency range, with a typical increase or decrease of 15dB. We have adopted a new III type noise reduction circuit, which has improved the signal-to-noise ratio by 20 decibels. Built in limiter, with a high threshold range from 0 to +24DBU.

Equalizer with built-in amplitude limiting:
- For general audio system configurations, engineers will add limiters between the equalizer and amplifier to protect the audio from overload or special audio effect processing. 2231 meets the needs of the public by combining the equalizer and limiter into one, which not only reduces the cost of use, but also simplifies the system wiring, provides powerful functions, and is easy to operate.
