ASCENDO range
DSP ULN2-2604 D
The ASCENDO DSP ULN2-2604 D is a 2-channel DSP power amplifier intended for passive subwoofer, infrasonic or high-output bass duties where DSP, load stability and sustained current are central.
Where it fits best
Bi-amplified, very-high-sensitivity ASCENDO cinema loudspeakers where noise floor and precise FIR/IIR crossover control are critical.
What to pay attention to
The asymmetric LF/HF outputs are intentional. Use only with a verified crossover/profile and channel assignment; incorrect routing can damage compression drivers.
