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.

LAB. GRUPPEN reserve the right to alter functions or specifications without prior notice.
1) Specifications measured with 230 V regulated AC
2) Continuous power, two channels driven or peak power four chan-
nels driven. (Thermal protection may occur at high continuous power).
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.
