Graphic Equalizer - SE 230
Description:
Features:
- Stereo 1/3-Octave Design
- ±12 dB Boost & Cut Range
- Interpolating Constant- Q Bandwidth
- Low Cut Filters and Bypass
- 45mm Filter Slide Controls
- Grounded Center Detents
- Sound output transformers for balanced XLR
The adjustable filters are useful when it is desirable to band limit the audio signal. For instance, restricting high frequencies to match the incoming signal usually produces the most quiet system.
