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 1000 can drive a 2 ohms load, we recommend you to
keep the load impedance on 4 ohms or above in professional applica-
tions, which demand large amounts of continuous power.
4) Normal operation level 1/8 of full power or -9dB below clip point.
