STETSOM 8000 Digital Amplifier
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.
Input, output and audio controls
- 1COOLERS: It provides cooling of the amplifier. Install in a cool place without obstruction of air inlets and outlets.
- INPUT: Input of the signal to be amplified. Connect to the radio/player through high quality shielded RCA cables to prevent unwanted noise.
- LEVEL: Signal level control in the amplifier input.
- CROSSOVER
- FILTRO HIGH PASS (HPF): This variable control allows you to select the initial frequency from 10Hz to 90Hz that will be reproduced by the amplifier.
- FILTRO LOW PASS (LPF): This variable control allows you to select the final frequency from 90Hz to 12KHz that will be reproduced by amplifier.
- BOOST: Variable control for bass boost from 0 to + 10dB.
- FREQ: Variable control for BASS boost action from 30Hz to 70Hz.
- FLAT: This switch allows you to turn the FLAT mode on or off. Settings made on the CROSSOVER and BOOST controls will be turned off when using this mode.
- OUTPUT CONNECTOR (SPEAKERS): MONO output of amplified signal for speakers connection. Check the minimum impedance and polarities before performing the installation.
Power input
- 8. POSITIVE POWER SUPLY CONNECTOR: Connect to the positive battery terminal through a minimum 00 AWG cable with a fuse/circuit breaker (400A) as close to the battery as possible.
9. REMOTE CONNECTOR (REM): Allows automatic activation of the amplifier when turning on the radio/player. Connect to the remote output of the radio/player minimum of 18 AWG.
10. NEGATIVE POWER SUPLY CONNECTOR: Connect to the negative terminal of the battery using a cable minimum of 00 AWG .
Indicators LED
- POWER (blue LED): Indicates amplifier operation when it is on.
- PROT (top red LED): Indicates that the amplifier encountered malfunctions and entered protection mode, forcing it to shut down. Verify-in the protection table below the possible problem and turn on the amplifier again.
- CLIP (lower red LED): Indicates signal distortion at the amplifier output.
Smart protection system
In case of problems, the amplifier will turn off and the PROT LED will flash. Depending on the problem, the led will flash a certain number of times indicating the cause of the problem, as shown in the table below:
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.
Troubleshooting
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.
