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

1) Specifications measured with 230 V regulated AC
2) Continuous power, one channel driven or peak power
both channels driven. (Thermal protection may occur
at high continuous power).
Lab.gruppen reserve the right to alter functions or specifications without prior notice.
3) The VHF-protection turns off the channel for
frequencies above 20 kHz at full power.
4) Normal operation level 1/8 of full power or
–9dB below clip point.
