FBT DLM 260

A 2-in/6-out architecture designed as the "brain" of your system

The FBT DLM 260 fits within the logic of speaker management processors: centralizing filtering, protection, and signal distribution in one place to gain coherence and safety. With its 2 inputs and 6 outputs, it naturally sits at the heart of a multi-amplified sound chain, offering comfortable flexibility to distribute the channels (subs, low-mid, mid-high), create dedicated outputs (fills, delays), or structure zones in fixed installations. Its compact format facilitates integration in FOH, rental racks, or technical cabinets.

Who is the FBT DLM 260 for and in which applications does it excel?

This processor is aimed at rental companies, technicians, and integrators who want to secure a sound system and standardize their settings from one event to another. In concerts, it allows building a clean and robust system: precise filtering, dynamic control per output, and quick routing according to stage configuration. In clubs, multipurpose rooms, or places of worship, it becomes a reliable control point to manage sound zones and preserve speakers over time, even when multiple users take turns. It is also relevant whenever phase alignment and sub management (including cardioid) are priorities, to achieve clearer bass and better-controlled coverage.

Key features: filtering, protection, and phase alignment serving the result

Custom filtering for clean channel separation

The DLM 260 offers filtering tools dedicated to system construction: Hi-pass, Lo-pass, and custom Shelving. The goal is twofold: protect transducers (by avoiding unnecessary or harmful frequencies) and optimize clarity (by reducing overlap between channels). This type of filtering is especially useful to get the best from top cabinets + subs, but also to calibrate fills or nearfield speakers that do not require the full bandwidth.

Dynamic management per output: maintain impact without endangering the system

Each output channel features an RMS compressor and a Peak limiter, with time constants and an algorithm optimized for thermal and mechanical protection of the speakers. In practice, this contains excesses (transient peaks, prolonged level increases, overly dense content) while preserving a sense of dynamics. The expected result is a more stable, less aggressive sound and longer component lifespan, especially on systems driven at high levels or for extended durations.

DCL mode: fine and musical level control

The double compressor limiter (DCL) mode adds a particularly interesting approach when pushing the system without crushing it. It combines a two-band RMS compressor and a peak limiter, with adjustable HP/LP crossover frequency and separate parameters. This logic helps to differently control energy across frequency bands, maintaining low-end weight while avoiding harshness in the highs, or vice versa depending on system signature and music played.

ALL PASS filters: phase precision and cardioid subs

ALL PASS filters are valuable allies when the difference is made in alignment. They are indicated as useful for cardioid SUB configurations, for very precise phase transition alignment, and for alignment between different speakers and systems. Practically, these tools facilitate coherence between subs and tops, improve impact perception, and contribute to better bass directivity when the configuration allows, with a special configuration control matrix designed for these uses.

Free routing: adapt the sound distribution to the venue, not the other way around

The ability to freely assign the L, R, or L+R input to each output simplifies life on site. For example, you can feed some outputs in mono (fills, subs, delays) while maintaining a stereo mix on the front, or quickly build a distribution adapted to different zones. This flexibility results in faster settings and more confident operation, especially when venue constraints change from one date to another.
