This is the manual of a 24-bit AD/DA 80-bit DSP digital equalizer DS231A. This product has a 31-band graphic equalizer and 20 frequency ranges that can be adjusted to make the sound clearer and more transparent.
This manual begins with safety precautions for the DS231A graphic equalizer, including grounding requirements, keeping the unit away from moisture, children, and heat sources. It also explains the proper power‑line connection and how to handle damaged cables or components.
The following sections describe the front‑panel controls (gain sliders, range switch, channel link, bypass, limiter, low‑cut/high‑cut filters), rear‑panel connectors (XLR, TRS, RS‑485, power), DIP‑switch settings for output level and gain mode, and the device’s power specifications, dimensions, and weight. Detailed wiring diagrams and operating notes help users achieve optimal sound balance and avoid clipping or overload. This manual is written in Chinese.
