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 progressively reduced at
impedances below 1.7 ohms. The power amplifier can be run into short-circuits for a long time without damage, and is open circuit and mismatch proof.

3) Though the LAB 500 can drive a 2 ohms load, we recom-
mend you to keep the load impedance on 4 ohms or above
in professional applications, which demand large amounts
of continuous power.
4) Normal operation level 1/8 of full power or –9dB below clip point.
