The Pulz DSS24 is a 2 input 4 output Speaker Management Processor. The 2 input levels are displayed by rows of 6 level leds + 1 clip led, The 4 output levels are displayed by rows of 5 level leds + 1 clip led + 1 Limiter led.
The unit has 2 Analog Inputs, a stereo Digital Input, and 4 Analog Outputs. Each input has 5 parametric equalizers with adjustable Q and Frequency. Each output has 7 parametric equalizers, a High Pass and a Low Pass section of filters with slopes up to 24dB/Oct. Each Output also has the facility of activating Limiters which work on the signal RMS value.
Linking functions between inputs and linking functions between outputs are available. A function has been provided to lock the parameters of the system. This feature is useful for fixed installations.
The DSS24 comes with a PC based software for remote control. This software can be used to connect multiple units at the same time.
