| EQ2231 is a general graphic equalization with excellent function which is suitable for many kinds of sound adjustment in the audio projects.
Features:
- The EQ2231 is a two channel graphic equalizer that provides a generous +/-15dB of control range on each of 30 constant Q frequency bands.
- Centre bypass. When any eq fader is in its centre detent position,the filter is automatically bypassed, for optimum performance.
- Sweepable high pass filter, frequency adjustable from OUT (flat) up to 250Hz.
- LF Contour Smooth shelving filter, +/-6dB of gain at 50Hz. >> HF Contour Smooth shelving filter, +/-6dB of gain at 14 kHz.
- GAIN Used for overall unity gain adjustment. Adjustable from - infinity to +10dB.
- Triple-point clip detector that indicates red when the internal signal is clipping at any one of EQ filter,HF/LF contour and Gain.
- Precise LED indication. When EQ switch is off, the LED indicates the input signal level. When EQ switch is on, the LED indicates output signal level.
- Relay bypass. When switched out, or power fails, a high-quality relay switches the input signal directly to the output connectors.
- The high-quality relay drive incorporates a power on delay and AC power loss, ensuring that there is no possibility of on/off thumps being generated by the unit.
- The standard 3U structure, To make installation easier, we've provided different interface connectors.
