Digital Signal Processor - DSP 4080 |
Description
The POPE Professional® DSP-4080 was launched successfully a few years ago, with it’s rapid growing acceptance. It includes all necessary functions for loudspeaker management applications. From Hardware A/D-DSP-D/A selections, to Software EQ-Crossover-Limiter algorithm designs, it keeps the signal path clean and musical. Recent improvements make the DSP-4080 an easy choice among professionals who demand high sonic quality in the analog world. A complete set of parameters include I/O levels, delay, polarity, 6 bands of parametric EQ per channel, multiple crossover selections and full function limiters. Precise frequency control is achieved with it’s 1 Hz resolution. Input and outputs can be routed in multiple configuration to meet any requirement. The DSP-4080 can be controlled or configured in real time on the front panel or with the intuitive PC via USB or RS-485 or the optional Ethernet interface. Multiple setup storage and system security complete this professional package.
