The EQ 231 is an analog equalizer featuring TRS or XLR differential balancing input and output, with the option for stereo or subwoofer synthesis by adding left and right channels. Both channels have a x10 range selection switch and a 40Hz high pass filter. Each output includes a phase reversal switch. The device offers independent adjustment of average output power across all frequency bands and employs a 24dB/Linkwitz Reiley filter. It includes a stereo/mono status indicator LED to display the selected working mode.

The EQ 131, featuring advanced 31 bands DSP digital processor technology, excels in high-quality audio input and output processing, significantly outperforming traditional manually adjustable equalizers. Ideal for professional settings such as radio stations, recording studios, and home theaters, this unit boasts a sleek 1U standard slim rack design. It offers dual-channel synchronous control with precise 31-band EQ equalization and LED spectrum indicators, ensuring clear pitch visualization during use. The EQ 131’s standout feature is its real-time 31-band frequency point hopping, achieving 99% spectral accuracy. This, coupled with an efficient noise gate for superior noise reduction and various input/output interfaces like TRS6.35/RCA Lotus/XLR Cannon balanced interface, makes it a robust tool for audio enhancement. The device also includes an EQ bypass option, can store up to 10 user-defined modes, and is powered by a 220V supply.
