Basslink/Basslink X TROUBLESHOOTING • PROBLEM: POWER LED not lit. APPLICABLE TO BASSLINK WITH LEVEL CONTROL JACK AND BASSLINK X ONLY: CAUSES and SOLUTIONS: 1. Fuse is blown and needs replacement. 2. Head unit not functioning properly. Check remote voltage, and power, ground or remote connections. • PROBLEM: BassLink turns on before head unit is completely on and produces a “thump” sound. CAUSE and SOLUTION: For speaker-level connections, head unit is producing a false turn-on signal.
