SPEAKER PROTECTION
Each channel is fuse protected on the positive and negative power supply rails. Electronic short-circuit protection with a progressive
characteristic. The output power is turned off at shorted output. The power amplifier can be run into short-circuits for a long time
without damage, and is open circuit and mismatch proof.
DISTORTION
THD 20 Hz-20 kHz and 1 W-1000 W
THD at 1kHz and 1100W
DIM 30 at 500 W
CCIF (13 and 14 kHz) at 500 W
