Introduction

Thank you so much for choosing a Stetsom product! The chosen amplifier has been developed with the most advanced technology for those who are looking for high performance audio systems with one or more speakers and “pro car audio” system.

Before installing

Please read this manual carefully.

All product connections must be made with the product turned OFF.
A fuse must be installed between the amplifier and the battery is required to protect against overcharging. The fuse has to be installed as close to the battery as possible. Check the proper fuse for the amplifier according to its consumption.
Use gauges recommended in this manual to avoid the overheating of the cables to obtain maximum power.
Keep the cables as short as possible to increase sound fidelity and avoid potential power losses.
Route the installation cables as far away as possible from the original vehicle wiring as it may cause interference and noise in your audio system.
Perform the installation in a firm, ventilated and dry place.
Installation must be done by a qualified professional.

If you have questions , contact the store where the purchase or installation was made. For more information please contact our
Customer Service: BR +55 18 2104-9412.

Smart protection system

When the protection system detects a failure, the amplifier will turn off and the PROT LED will blink. For each type of failure, the LED will flash a certain number of times indicating the cause, as shown in the table below:

Diagnostic: Short circuit or output overload.
Solution: Check that the speaker cables are well insulated and that the output impedance does not exceed that supported by the amplifier.
Diagnostic: Excessive temperature. When the amplifier reaches approximately 194°F, audio is stopped and the coolers run at maximum speed to speed up the cooling process of the internal components.
Solution: Check if the amplifier is in a ventilated place or if the coolers are not obstructed. Keep the amplifier turned on for a few minutes for the coolers to assist in the cooling process.
Diagnostic: Supply voltage less than 9V.
Solution: Check voltage of battery or power supply.
Diagnostic: Supply voltage greater than 16V.
Solution: Check voltage of battery or power supply.

Installation

Specification of the cables for proper installation:

Power connectors (positive/negative) …………………………………. 00 AWG
Remote connector ……………………………………………………………. 18 AWG
Output signal connectors (speakers) …………………………………… 7 AWG
Fuses or circuit breakers …………………………………………………….. 400A

The use of fuse or circuit breaker is mandatory to protect the system from short circuit and overload. Install them as close to the battery as possible.

Installation should only be done by qualified professionals with the product turned OFF. STETSOM-8000-Vulcan-Digital-Amplifier-fig 8

Troubleshooting

THE AMPLIFIER DOES NOT TURN ON:

Verify that the cables are connected correctly. Make sure all connections have electrical and mechanical contact.
Fuses or circuit breakers may be defective or blown. Check the condition of the circuit breakers and if it is compatible with the equipment consumption.
Verify that the battery charge is sufficient for the operation of the product. NO SOUND:
The cables of the speakers or RCA plugs may not be connected correctly or are defective.
Verify that the LEVEL control is not at a minimum.
PROT LED FLASHING:
Verify that the product vents are not blocked or the product is overheated.
Speakers or cables shorted, check speakers, cables and connections.

SOUND DISTORTIONS:

The speakers may be overloaded or defective, lower the level and remake the level adjustment. This setting can be adjusted as follows:
- a) On the radio/player, place any musical signal and set the volume to 80% of the maximum (if the maximum volume of the radio /player is 45 (100%), set to 36 (80%).
- b) On the amplifier, with LEVEL control at minimum, increase gradually until the LED CLIP starts to flash. Slowly return the LEVEL until the led goes out completely.

LACK OF BASS:

Cables of the speakers may be reversed and (out-of-phase speakers). NOISE AND FAILURE IN SOUND:
Verify that the installation is not close to the original vehicle wiring as they may cause interference and noise in the audio signal.
Make a separate power connection to the sound system. Use a fuse/circuit breaker as close to the battery as possible for protection.
Make a good grounding of the amplifier. To do this, remove the paint from the vehicle chassis at the desired point. Screw the wire using a ground terminal. To protect from oxidation, isolate with paint.
Do not loop the ground. Avoid using multiple grounds. If possible, use a star connection, in which all the grounds run from a single point.
