I often see on here people recommending the use of relays when multiple remote turn-on leads are used. I understand The basic principle of a relay & what they do, but have yet to use one. I have three amps, & all three remotes are spliced together coming from the EQ. Where can I find a good, detailed diagram or instruction page pertaining to how & what type of relay I should use? Thanx in advance.
