System tuning

Install all system fuses.
Set the amplifier’s input sensitivitycontrols to their minimum positions (fullcounterclockwise).
Set all amplifier signal routing switchesaccording to your system’s design.
Make preliminary adjustments to the crossover frequency,usually 80Hz is good starting point for high and low pass. It maybe necessary to fine tune the crossoverfrequency later for the best overallsound quality.
If using an Remote Level Control, set itto maximum (full clockwise).
Turn the head unit on with the volume set to minimum.
Visually check the amplifier’s has powered on by the powerLED.
Check the condition of all other components to make surethey are powered up.
Set the headunit’s tone controls, balance, and fader to thecenter (flat) position. Turn off any loudness or other signalprocessing features.
Set the volume control of the source unit for maximum undistorted output (on mostheadunits / media devices this will beapproximately 7/8 of maximum volume). Use avery clear and dynamic recording.
Turn up the input level control until the speakers reachmaximum undistorted output.
12. Repeat input level adjustments for all other amplifiers.
Reduce the source unit volume to a comfortable level.
Listen to various musical selections to check overall systembalance. Compare front to rear, midbass to midrange, etc. Ifone speaker set is too loud compared to another, then its levelmust be lowered to blend correctly with the other speakers.The idea is to reference all speakers to the weakest set.
Fine tune crossover frequencies to achieve the smoothestpossible blending of each speaker set.
With all levels set correctly, the system will reach overallmaximum undistorted output at the volume level set in step 10.

Volume Control with Mute FunctionThe included volume control will allow for +/- 20dB of leveladjustment from the remote based on the level set in the previousstep.In some instances this will not be enough to completely mute theoutput level depending on the amount of input signal. In thesecases, a mute function allows for instant mute of output withoutadjusting the volume control.To activate the mute function, press the volume control knobinward until it clicks.To return to previous output level; press the control knob again.

Troubleshooting

No power:

Check voltage at amplifier with a DMM (volt meter), B+and REM (with head unit on) the voltage should register between12.2V and 14.6V when using the attached ground lead of theamplifier. Check fuse at amplifier and at the battery. Use a meterto verify connection from one end of the fuse to the other, breaksmay not always be visible. If the fuse is blown, check the powerwire and also the amplifier for a short. If the short is in the amplifieritself, see your Stinger dealer. If no short is present, replace thefuse.Power without sound:

Turn the amplifier off and check all input andoutput signal cables and power connections. Check the speakersfor shorts with a DMM (volt meter) or by connecting them toanother audio source. After making sure everything is correct, turnthe amplifier on again.“Motor Boating” – the power indicator going off repeatedly whenthe audio system is on: Check the amplifier’s connection to thebattery. Check battery voltage. If low, recharge or replace thebattery. Check all ground connections.Power without sound and the PROTECT LED is lit: The red PROTECTLED lights when the amplifier shuts down for either thermal or overcurrentprotection. A high internal amplifier operating temperaturewill trigger thermal shutdown: after it cools about 5°C, the amplifierwill restart. A shorted speaker lead or operation into unusually lowimpedance loads will trigger over-current shutdown: cycle powerat the amplifier REM terminal to restore operation. Check forshorted speaker wiring or damaged speakers or crossover systemsif over-current shutdown occurs.No sound from one side: Check the balance control in the headunit. Check speaker connections. Check signal input connection.Frequent amplifier shutdown with automatic recovery: Thisindicates chronic amplifier thermal shutdown because ofoperation at consistently high internal temperatures. Highoperating temperature can be caused by inadequate ventilation.Make sure you are not running a lower than recommendimpedance. Also check for damaged speakers or passivecrossover systems. Finally, chronic thermal shutdown may resultfrom otherwise normal operation of the amplifier at elevatedoutput power levels, which can be resolved by providingadditional amplifier cooling, installing a higher-power amplifier, orreducing amplifier output level.Very low output: Check your head unit’s fader control or theamplifier’s input sensitivity level. Make sure HP frequency control isnot set too high and LP frequency control is not set too low at thesame time.WARRANTY:LIMITED WARRANTY ON AMPLIFIERSStinger warrants this product to be free of defects in materials andworkmanship for a period of one (1) years from the original dateof purchase.
