Delta 48
4-IN 8-OUT Loudspeaker Processor, Matrix & Controller
Product at a Glance
The Delta 48 is a high-performance 4-input 8-output loudspeaker processor designed to meet the demands of sophisticated loudspeaker management, live sound, and installations. Powered by a 96kHz DSP engine, it ensures pristine audio quality with minimal latency. Equipped with powerful Dynamic EQ, Visualised Transparent Compression, and Automatic Gate Compensation, the Delta 48 provides seamless system optimization across all outputs. Comprehensive crossover options like Linkwitz-Riley, Bessel, and Butterworth filters allow precise tuning and seamless integration with any loudspeaker system.
The unit features 6 filters per input/output, fully configurable for parametric, low-shelf, high-shelf, and all-pass filtering, offering maximum flexibility. A 4-input and 8-output metering system with a DSP control panel ensures intuitive control and monitoring. With robust RS 485 and USB connectivity, and a rugged black aluminium chassis with a brushed steel front panel, the Delta 48 combines touring-grade durability with installation-grade precision. A lightweight powerhouse, the Delta 48 is the go-to choice for serious sound engineers demanding flexibility, reliability, and sonic accuracy.
CRAFTSMANSHIP
Painstakingly Perfect Production
Over the years, craftsmanship has been closely linked with small scale individualistic production. Back in 1972, we started the same way. As we grew in scale & size, it was difficult to build each speaker individually, but quality control was of utmost importance as so switching to a general assembly line was simply not an option. So we wrote up a code, one quite like enigma, to ensure quality control. We selected the right partners, got the right tools, and in cases where those weren't available, we invented them. We grew slower than most as our aim was to last longer than most.
