Connect the AC/DC power supply to the SpotDAP unit first, then to the
correct voltage power source. The SpotDAP unit will automatically turn
on. The Status LED wil show green. See page 5 for more detail in
connecting the AC/DC power supply to the SpotDAP unit.
Adjusting the SpotDAP unit volume:
The SpotDAP unit requires audio from a line level external audio
source, with volume control such as a CD player, DVD player or
MP3 player.
Stop the external audio source.
Connect the RCA cables.
Turn the external audio sound on.
Adjust the external audio source’s volume until you reach
the desired level from the SpotDAP unit.
When the SpotDAP unit detects that incoming signals are signifi-
cantly beyond the input rating of the unit, it automatically lowers
the signal until the limiter can reduce the input level to within
operating limits.
Adjusting the SpotDAP EQ settings:
The SpotDAP unit comes programed with 3 selectable EQ
settings. See page 22 for frequency response plots showing the
effect of each EQ setting. The factory default is EQ setting #1.
!
NOTE:
It is always best to begin with a low volume level at the source.
