dbx 286S Mic Preamp/Channel Strip Processor

The dbx 286S is a compact, single‑channel microphone preamplifier and channel strip processor that delivers studio‑grade sound in a small footprint. Designed for both live and recording environments, it combines high‑quality preamp circuitry with versatile processing options to shape vocals, instruments, and any other source signal.

Core Features

• Microphone Preamp: The 286S provides a clean, low‑noise gain stage that can boost signals up to +30 dB. Its high‑dynamic range and flat frequency response preserve the natural character of the source.
• Compression & Limiting: A built‑in compressor/limiter offers adjustable attack, release, ratio, and threshold controls. This allows you to tame peaks or add punch without sacrificing clarity.
• EQ Section: The integrated equalizer features a low‑pass filter with selectable cutoff frequency (up to 20 kHz) and a high‑gain boost for the mid‑range, giving precise tonal shaping capabilities.
• Gain Staging & Metering: A dedicated gain knob and LED meter provide real‑time feedback on signal level, ensuring optimal headroom throughout the chain.
• Versatile Connectivity: The unit offers XLR input and output for balanced audio, as well as a 1/4" TRS line out. This makes it compatible with mixers, interfaces, and other studio gear.
• Compact Design: With dimensions of just 3.5 inches wide by 2.5 inches tall, the 286S fits easily on a rack or in a small studio setup without compromising performance.

Applications and Use Cases

The dbx 286S excels in a variety of scenarios:

• Live Sound Reinforcement: Its low latency and robust construction make it ideal for front‑of‑house or monitor mixes where quick, reliable signal processing is essential.
• Studio Recording: Engineers use the preamp to capture vocals, acoustic guitars, drums, and other instruments with a transparent boost before applying compression or EQ as needed.
• Broadcast & Podcasting: The built‑in limiter ensures consistent levels for spoken word content, while the EQ section helps shape voice tone for clarity on radio or streaming platforms.
• Field Recording: Portable and durable, the 286S can be mounted in a mobile rig to provide high‑quality preamp and processing on location.
