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 . * This amplifier has high input connection . High level input is used from radios that do nol have line - level outputs. * Be sure not to use both low and high level inpu ts simultaneously ! SPEAKER OUTPUT CONNECTIONS You do nol 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 VOLUM E 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 . 9
