AMPLIFIER FUNCTIONS
- 1 2 VOLT POWER
CONNECTS THIS TERMINAL THROUGH A FUSE OR CIRCUIT BREAKER TO THE POSITIVE TERMINAL OF THE VEHICLE BATTERY OR THE POSITIVE TERMINAL OF AN ISOLATED AUDIO SYSTEM BATTERY. - G N D
CONNECTS THIS CABLE DIRECTLY TO THE FRAME OF THE VEHICLE. MAKE SURE THE METAL FRAME HAS BEEN STRIPPED OF ALL PAINT DOWN TO THE BARE METAL. USE THE SHORTEST DISTANCE POSSIBLE. IT IS ALWAYS A GOOD IDEA TO REPLACE THE FACTORY GROUND AT THIS TIME WITH A LARGER CABLE EQUAL TO THE NEW DIRECTLY TO THE VEHICLE BATTERY GROUND TERMINAL OR ANY OTHER FACTORY GROUND POINTS. - RCA INPUT
THESE RCA INPUT JACKS CONNECT WITH YOUR SOURCE UNIT RCA LOW-LEVEL OUTPUTS OR VIA AN OPTIONAL HI-LO ADAPTOR. THE USE OF HIGH-QUALITY TWISTED PAIR CAR AUDIO CABLES IS RECOMMENDED TO PREVENT POSSIBLE DISTURBANCE OF THE AUDIO SIGNAL. - REMOTE(MONOBLOCKS)
CONNECT THE REMOTE CONTROLLER TO CONTROL THE SUBWOOFER AMPLIFIER VOLUME FROM THE DRIVER SEAT LOCATION, FOR EASE OF ADJUSTMENT DURING PLAYING. - LOw PASS FILTER CONTROL
THIS CONTROL IS USED TO SELECT THE DESIRED LOW PASS X-OVER FREQUENCY. THE FREQUENCY CAN BE ADJUSTED FROM 90Hz TO 20KHZ FOR ALL NON-FULL RANGE AMPLIFIERS. - HPF FILTER CONTROL
THIS CONTROL CAN FILTER OUT UNWANTED LOW FREQUENCIES FROM 10HZ – 2KHZ. THIS FUNCTION WILL INCREASE THE POWER HANDLING OF YOUR WOOFERS. - THE BASS BOOST LEVEL KNOB
THIS CONTROL ADJUSTS THE BASS BOOST LEVEL OF THE BASS BOOST CENTER FREQUENCY. IT CAN BE ADJUSTED FROM 0 TO 10 DB. COMBINING THIS WITH THE BASS BOOST FREQUENCY YOU CAN ACCURATELY MATCH THE AMPLIFIERS PERFORMANCE TO THE WOOFER FREQUENCIES. - BASS BOOST FREQ KNOB CONTROLS
THE BOOSTED CENTER FREQUENCY. THE FREQUENCY CAN BE ADJUSTED FROM 30Hz TO 70Hz ACCORDING TO THE CAR AUDIO SYSTEMS PERFORMANCE. (WHEN YOU ADJUST THIS KNOB TO 50HZ THE AMPLIFIER WILL BOOST THAT FREQUENCY) THIS FUNCTION SHOULD BE ADJUSTED IN COMBINATION WITH THE BASS BOOST CONTROL. - SPEAKERS
CONNECT SPEAKERS/SUBWOOFERS TO THESE TERMINALS. BE SURE TO CHECK WIRING FOR PROPER POLARITY. NEVER CONNECT THE SPEAKER CABLES TO THE CHASSIS GROUND.

FIG 5. MONO AMPLIFIER WIRING (MULTI-WOOFER LOAD)
*EQUIVALENT PARALLEL WOOFER LOADS CAN NOT BE LESS THAN THE MINIMUM STABLE LOAD RATED IN THIS MANUAL. THE TWO NEGATIVE AND TWO POSITIVE SPEAKER TERMINALS ARE WIRED INTERNALLY INSIDE EACH AMPLIFIER. ONLY ONE NEGATIVE AND ONE POSITIVE ARE NEEDED WHEN WIRING TO THE AMPLIFIER. THESE ARE MONO-BLOCK AMPLIFIERS AND NOT MULTI-CHANNEL AMPLIFIERS. THE MINIMUM LOAD FOR ALL” DRAGO”(MONOBLOCK) AMPLIFIERS IS ONE OHM.
TROUBLESHOOTING
| Symptom | Possible Remedy |
| The amplifier will not power up | Check to make sure you have a good ground connection. Check that there is battery power on the (+)terminal. Check all fuses, and replace them if necessary. Make sure that the Protection LED is not illuminated. |
| Protection LED Comes on | Check for short circuits on speaker leads. Check that the speaker load is not beyond the minimum load. Remove speaker lead, and reset the amplifier. If the protection LED still comes on, then the amplifier is faulty and needs servicing. |
| No output | Check that the RCA audio cables are plugged into the proper inputs. Check all speaker wiring. Check the head unit output and the amplifier level setting. |
| Low output | Reset the level Control. Check the Crossover Control settings. |
| High hiss in The speakers | Check the RCA cable is not shorted to power ground at the amplifier side. Check the amplifier grounding. |
| Distorted sound | Check that the Input level control is set to match the signal level of the head unit. Always try to set the Input level as low as possible. Check that all crossover frequencies are properly set. Check for short circuits on the speaker leads |
| Amplifier gets Very hot | Check that the minimum load impedance for the amplifier model is correct. Check that there is good air circulation around the amplifier. In some applications, It may be necessary to add an external cooling fan. Do not mount the amplifier upside down. |
