    • When rack-mounting, use nylon washers on both sides of the ears to isolate the amplifier from the rack and prevent ground loops and hum problems. • Very sensitive low-level sources might pick up some hum radiated from the 875D SE’s power supply. If this occurs, move the unit away from the other components.

    ® Bronze Interconnects. If source components are more than 20 feet from the amplifier, use the Sonance LS2 and LR2 Balanced Line-Level Sender and Receiver (sold separately) to avoid signal degradation. NOTE: Always check local building codes before installing wire in walls or ceilings.

    For the best sound you should never use thin-gauge speaker wire – it will constrict the sound and diminish bass response. We recommend that you use premium Sonance MediaLinQ speaker cable, which also complies with UL fire rating codes. You may also experiment with audiophile brands of speaker cable and interconnects, but be sure to check local codes governing wire that may be installed within walls or ceilings.
