dbx 231 2-Series Graphic EQ

The dbx 231 2-Series Graphic EQ is a professional audio equalizer designed for live sound reinforcement, recording studios, and sound installations. Here’s a description of its features and functionality:

1. Graphic Equalization: The dbx 231 features two channels of 31-band graphic equalization per channel, allowing precise control over the audio frequency spectrum. Each band represents a specific frequency range, and you can boost or cut the level of each band to shape the sound according to your preferences.
2. Constant-Q Filtering: The EQ filters in the dbx 231 employ constant-Q technology, which ensures that the width of each equalization band remains consistent regardless of the boost or cut level. This means that neighboring bands are not affected when you adjust a specific band, providing more accurate and predictable results.
3. Input and Output Connections: The unit provides balanced XLR and 1/4-inch TRS input and output connections, making it compatible with a wide range of audio equipment. These connectors offer reliable and noise-free signal transfer.
4. Adjustable Gain Range: The dbx 231 offers a selectable boost/cut range of either ±6 dB or ±12 dB. This flexibility allows you to make subtle adjustments or more drastic changes to the audio signal.
5. Low-Cut Filter: Each channel of the EQ includes a switchable 40Hz low-cut filter. This filter helps eliminate unwanted low-frequency rumble and noise from the audio signal, ensuring cleaner and tighter bass response.
6. Output Level Metering: The dbx 231 features dual 12-segment LED meters that provide visual feedback of the output signal levels for each channel. This allows you to monitor the output levels and avoid clipping or distortion.
7. Bypass Switch: The unit includes a dedicated bypass switch that lets you instantly bypass the EQ section, allowing the original signal to pass through unaltered. This can be useful for comparing the equalized sound to the original or for temporary disengagement of the EQ.
8. Rugged Construction: The dbx 231 is built with a sturdy and durable metal chassis, designed to withstand the rigors of professional use. Its robust construction ensures reliability and longevity.

Overall, the dbx 231 2-Series Graphic EQ offers precise and flexible equalization capabilities for audio professionals, enabling them to shape and fine-tune the sound to suit various applications and venues.
