4 CHANNEL AMPLIFIER - APPLICATIONS
INPUT CONNECTIONS
*
This amplifier has RCA connections for low level inputs. Low level signal is carried
through RCA cables. it is preferred to use low level inputs to the amplifier if the head
unit is equipped with the low level outputs.
SPEAKER OUTPUT CONNECTIONS
You do not need to make any adjustment for the input connection of amplifier before
you connect the speaker output.
*
Connect right and left speaker wire to corresponding speaker output terminals of the
amplifier.
*
Be sure to have the positive wire from the speaker to the positive speaker terminal
of the amplifier and the negative wire from the speaker must connect with the speaker
terminal of the amplifier. Reversing any of these connections will result in the speaker
cones moving out of phase which causes bass cancellation.
LEVEL CONTROLS
Turn the VOLUME control on the amplifier to Min initially.
Once the initial power sequence has been performed, set the CD/RADIO volume
control to roughly 80% of full. Insert a CD or tune to a radio station and slowly turn
up the amplifier VOLUME control until you hear some distortion, and then back it off
for clean sound.
