Description
The DLM26 is a DSP based 2 input 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.The DLM 26 features superb audio quality with premium hi-end AKM5392 24bit A/D converters and AKM 4396 24bit D/A converters, carefully optimized double precision signal processing coupled with 24bit conversion ensure a dynamic range >110db.
The unit can work in STANDARD MODE or in DCL MODE. The first mode permit to configure the crossover in 2×2 way + SUB, 2×3 way or 6way, the input L, R, L+R are freely assignable to each output.
In DCL mode the unit can be configured in 3ch DCL, 2ch DCL + 2ch standard, 1ch DCL + 4ch standard. DCL mode mean double compressor limiter, each DCL channel have a double band limiter and compressor with assignable LO/HI split frequency. This is an exclusive feature in digital processor and its very useful to protect two way passive filters with no passive attenuation in the crossover between LF woofer and HF driver. With DCL mode is possible to set two different threshold of protection for woofer and driver with the split frequency corresponding to the passive crossover frequency.
Each input has 5 fully configurable filters, a delay of 288.66ms max in step of 6.8us, gain.
The 2 input levels are displayed by rows of 6 level LED + 1 clip led, the 6 output levels are displayed by rows of 5 level LED + 1 clip led + 1 Limiter led. The unit has 2 analog inputs, a stereo digital SPDIF input, and 6 analog outputs.
Linking functions between inputs and linking functions between outputs are available.
A function is allowing to have ramps closing the output level on parameter changes, when the
unit is used as installation unit; this function can be excluded when the unit is used live and it is necessary to perform small changes to the set parameter…on the fly.
The Pc SW for the remote control via RS485 or USB is allowing to connect in net up to 32 units and is allowing to control full parameters of the processor, to show the phase of the filter setting and to adjust graphically the RMS compressor and the Peak limiter. The comprehensive standard specification also include up to 64 memories with security lockout and two password level settings.
