PRODUCT DESCRIPTION
The DLM 260 is a DSP based 2 inputs x 6 output digital loudspeaker management processor, ideally suited for fixed installations and live events. It combines the functions of a multitude of conventional products in a compact 1U unit with extensive PC remote control capabilities.
Routing is freely assignable from the two inputs to the six outputs. Input and output equalisation is available with a choice of 16 filter options. A total of 31 IIR EQ is available for each input, or 32 user memory locations is also available. Many options for crossover type include IIR from 6 to 48dB/oct, FIR and Linear Phase with constant group Delay. Input and output delay is available to time align components in a system; RMS and peak limiters will protect your speakers from damage due to excessive power being applied.
On input paths, the processing chain sees in cascade: input gain / delay / noise gate / dynamic loudness / filtering section / RMS Compressor.
On output paths the processing chain sees in cascade: output gain / delay / polarity/ filtering section / RMS compressor / peak limiter.
The processor features 32 user memory locations to store popular configurations and settings can be exported to a file via the dedicated PC application, either as a back-up or to store more favourite configurations if the 32 on-board presets are not sufficient. A very useful function is the ability to recall entire output channel configurations. PC connectivity is available via a front panel USB port but for larger systems with several processors can use Ethernet or RS-485 network connections.
