5.1 unpacking Carefully open the shipping carton and check for any noticeable damage. Every Lab.gruppen amplifier is tested and inspected before leaving the factory and should arrive in perfect condition. If any damage is discovered, please notify the shipping company immediately. -
Page 10: Grounding
5 INsTALLATION 5.5 Grounding There is no ground lift switch or terminal on the C Series amplifiers. The signal ground is always floating, via a resistor, to chassis and therefore the grounding system is automatic. In the interests of safety, never disconnect the earth (ground) pin on the AC power cord. - Page 11 ThIs PAGE INTENTIONALLY LEFT BLANK C Series C 20:8X, C 10:8X, C 10:4X and C 5:4X Operation Manual 11 11...

7 OPERATION AND PERFORMANCE at the cost of headroom. The C Series amplifiers work on globally set constant gain, and automatically compensate the input gain by -6 dB. For example, if the amplifier is configured in a three channel mode, then the selected gain is maintained from input to output on all channels. -
Page 19: Constant Voltage 70 V And 100 V Systems Setup And Operation
To configure an individual output channel for a constant voltage system, you simply adjust the DIP-switches to the desired voltage. However, when using an output for a low-impedance system ( 4, 8 or 16 ohms), then sometimes you need to adjust the VPL to a lower setting to avoid either delivering excessively high continuous power to the speaker or overheating of the output channel through... -

Page 21: Dc Protection
The Attack time for the VHF protection is increa- singly shorter at higher frequencies. For example, an ultrasonic continuous signal will cause the outputs to mute rapidly, where it will take several milliseconds for a 10 kHz continuous signal to trigger the output mute. -
Page 22: Soft-Start
7 OPERATION AND PERFORMANCE 7.6.8 Soft-start High powered amplifiers with inadequate inrush limiting can pull considerable current from the mains at turn-on. This can result in fast acting mains breakers tripping. Such is not the case with C Series amplifiers. The C Series amplifiers have very low inrush power as the capacitors are charged slowly and in a controlled manner ensuring that breakers will not trip. -
