Example-3: RCA Input from Aftermarket Radio
Example-4: RCA Input from Portable Audio Player
Note: When using a receiver’s internal power IC to drive speakers directly and its RCA
outputs to the linkD for external amplifiers, note that speaker outputs will usually clip at a
lower volume level than RCA outputs. Adjust gain settings accordingly for matched
unclipped volume range.
Note: Portable devices such as smartphones or MP3 players typically have an output
voltage of 1Vrms or less. While the linkD’s auto turn-on circuit will detect very low signal
levels, in some cases the gain may need to be adjusted for reasonable listening levels but
with reduced total volume range when using the device as the system’s volume control.
