System tuning
1. Install all system fuses.
2. Set the amplier’s input sensitivity
controls to their minimum positions (full
counterclockwise).
3. Set all amplier signal routing switches
according to your system’s design.
4. Make preliminary adjustments to the crossover frequency,
usually 80Hz is good starting point for high and low pass. It may
be necessary to ne tune the crossover
frequency later for the best overall
sound quality.
5. If using an Remote Level Control, set it
to maximum (full clockwise).
6. Turn the head unit on with the volume set to minimum.
6. Visually check the amplier’s has powered on by the power
LED.
8. Check the condition of all other components to make sure
they are powered up.
9. Set the headunit’s tone controls, balance, and fader to the
center (at) position. Turn off any loudness or other signal
processing features.
10. Set the volume control of the source unit
for maximum undistorted output (on most
headunits / media devices this will be
approximately 7/8 of maximum volume). Use a
very clear and dynamic recording.
11. Turn up the input level control until the speakers reach
maximum undistorted output.
12. Repeat input level adjustments for all other ampliers.
13. Reduce the source unit volume to a comfortable level.
14. Listen to various musical selections to check overall system
balance. Compare front to rear, midbass to midrange, etc. If
one speaker set is too loud compared to another, then its level
must be lowered to blend correctly with the other speakers.
The idea is to reference all speakers to the weakest set.
15. Fine tune crossover frequencies to achieve the smoothest
possible blending of each speaker set.
16. With all levels set correctly, the system will reach overall
maximum undistorted output at the volume level set in step 10.
Volume Control with Mute Function
The included volume control will allow for +/- 20dB of level
adjustment from the remote based on the level set in the previous
step.
In some instances this will not be enough to completely mute the
output level depending on the amount of input signal. In these
cases, a mute function allows for instant mute of output without
adjusting the volume control.
To activate the mute function, press the volume control knob
inward until it clicks.
To return to previous output level; press the control knob again.

Troubleshooting
No power: Check voltage at amplier with a DMM (volt meter), B+
and REM (with head unit on) the voltage should register between
12.2V and 14.6V when using the attached ground lead of the
amplier. Check fuse at amplier and at the battery. Use a meter
to verify connection from one end of the fuse to the other, breaks
may not always be visible. If the fuse is blown, check the power
wire and also the amplier for a short. If the short is in the amplier
itself, see your Stinger dealer. If no short is present, replace the
fuse.
Power without sound: Turn the amplier off and check all input and
output signal cables and power connections. Check the speakers
for shorts with a DMM (volt meter) or by connecting them to
another audio source. After making sure everything is correct, turn
the amplier on again.
“Motor Boating” - the power indicator going off repeatedly when
the audio system is on: Check the amplier’s connection to the
battery. Check battery voltage. If low, recharge or replace the
battery. Check all ground connections.
Power without sound and the PROTECT LED is lit: The red PROTECT
LED lights when the amplier shuts down for either thermal or over-
current protection. A high internal amplier operating temperature
will trigger thermal shutdown: after it cools about 5°C, the amplier
will restart. A shorted speaker lead or operation into unusually low
impedance loads will trigger over-current shutdown: cycle power
at the amplier REM terminal to restore operation. Check for
shorted speaker wiring or damaged speakers or crossover systems
if over-current shutdown occurs.
No sound from one side: Check the balance control in the head
unit. Check speaker connections. Check signal input connection.
Frequent amplier shutdown with automatic recovery: This
indicates chronic amplier thermal shutdown because of
operation at consistently high internal temperatures. High
operating temperature can be caused by inadequate ventilation.
Make sure you are not running a lower than recommend
impedance. Also check for damaged speakers or passive
crossover systems. Finally, chronic thermal shutdown may result
from otherwise normal operation of the amplier at elevated
output power levels, which can be resolved by providing
additional amplier cooling, installing a higher-power amplier, or
reducing amplier output level.
Very low output: Check your head unit’s fader control or the
amplier’s input sensitivity level. Make sure HP frequency control is
not set too high and LP frequency control is not set too low at the
same time.
