Connection to main power supply before connecting the amplifier to a power socket, always make certain that: 1. The electric system and power socket have adequate grounding compatible with the safety norms (if you are uncertain, consult specialized personnel); 2. The power supply voltage corresponds...

Preventing or identifying interference first of all, check that the amplifier is installed in a place free from industrial or rf (radio frequency) interference. Avoid installing your equipment very near tv sets, mobile phones, etc., as these can cause noisy interference. When connecting the other co...
Page 7: Sound Reinforcement Basics
Sound reinforcement basics the speaker output jacks on the g-series amps are designed to power up to two core (or other brand) 8 ohm speakers, or up to four hot spot 16ohm speakers per channel. Most professional-type speakers (like the core and hot spot) have two jacks which are wired in parallel (m...

The following diagrams show the wiring of the connectors that can be used with g-series amplifiers. To connect the mixer outputs to the amplifiers inputs, make certain to always use balanced signal cables: the use of unbalanced cables could cause annoying hum and noise. To connect the amplifier to t...
