Graphic Equalizer - SE 230 |
|
Description: The SE230 is a two channel, 1/3-octave constant Q micrographic equalizer. The SE230 utilizes 45 mm sliders. Two adjustable band limiting filters add to each Channels’ versatility. And the SE230 added an audio output transformer in the out put channel, which make the nonlinear distortion lower to 0.008 % and increase the SE230 load capacity. SE230 has extremely low background noise. The S/N ratio can reach higher to 112dB when the fader in middle. While the Fader is in the highest gain, S/N ratio also can reach to 84dB. 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
Application:
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.
