I have a Boss OL5KD Class D Monoblock Amplifier and I set it up but is no sound coming up from the speakers, can anyone tell me how to higher the volumen? where is located the volumen??I need to higher the...
The Boss OL5KD does not have a volume control. It has an "Input Level" adjustment which is used to match the output from your head unit preamp output to the amp. It is the first rotary control just to the right of the input jacks.
If you have no sound at all, I'd suspect that something is incorrectly connected or there is no input to the amp. First make sure that the amp power light (green LED) is coming on when you turn on the receiver and that the protection light (red LED) stays off. Then check all of your wiring, especially the RCA output cables.
Initially set the controls like this: MASTER/SLAVE switch in MASTER position (left). INPUT SENSITIVITY 2v-8v (right). INPUT LEVEL, SUBSONIC FILTER, BASS BOOST, and LOW PASS FILTER; midrange. PHASE SHIFT "0" (left). Leave the remote level control disconnected.
After you've checked all wiring and initially set the switches and controls, turn the receiver on to about 3/4 volume. Now adjust the INPUT LEVEL to the left just until you begin to hear distortion, then turn it back right just a little. Adjust the other controls for best sound. Plug in the remote level control and make sure that it adjusts the bass up and down. You're finished!
If there's still no output from the unit after checking all of the wiring, either the unit is defective, it's not getting an input from the receiver, or the sub(s) are defective.
Hope this helps.
