2 For each channel, the red terminal on the loudspeaker should be connected to the red or (+) loudspeaker connection terminal on the receiver or amplifier, and the black to the black or (­). Connecting the loudspeakers in this manner ensures that they will be in phase; that is, work together rather than in opposition. Connecting the loudspeakers out of phase will not damage them, but will result in less bass and poor imaging. G SERIES LOUDSPEAKERS TROUBLESHOOTING The vast majority of new speaker "malfunctions" end up being traced to connections or switch settings. Check the following tips first, before requesting service. No sound at all or very faint sound from both speakers 1. Amp/receiver tape monitor button pushed in while using CD, FM or phono inputs. Wrong speaker switch, "A" or "B" speaker output.

Balance control turned all the way left or right. Speaker wire has become disconnected. Both speakers play at low volume but shut off as volume is increased OR sound turns on and off intermittently A few strands of speaker wire may be shorting out. Recheck the connections.
