Introduction

Thank you so much for choosing a Stetsom product! This amplifier was developed with cutting-edge technology for those who want high quality sound from audio systems with one or more speakers or even an audio wall system.

Before installing

Please read this manual carefully.

• All 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 overcurrent. The fuse needs to be installed as close to the battery as possible. Choose an appropriate fuse for the amplifier based on its consumption.
• Use the wire recommended in this manual to keep cables from overheating cables and 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 to prevent interference and noise in your audio system.
• Perform the installation on a firm surface in a ventilated and dry place.
• Installation should only be done by a qualified professional.
  If you have questions , contact the store where the purchase or installation was done. For more information please contact our Customer Service: BR +55 18 2104-9412.

Input, output and audio controls

1. RCA JACK INPUT: Input of the signal to be amplified. Connect to the radio/player using high quality shielded RCA cables to prevent unwanted noise.
2. LEVEL: Level control for the signal at the amplifier’s input.
3. CROSSOVER:
   • SUBSONIC FILTER: This variable control allows you to select the initial frequency from 8Hz ~ 40Hz that will be reproduced by the amplifier.
   • LOW PASS FILTER (L.P.F.): This variable control allows you to select the final frequency from 30Hz ~ 250Hz that will be reproduced by the amplifier.
4. BASS BOOST:
   • BASS: Variable control for bass boost from 0dB ~ +10dB.
   • FREQ: Variable control for BASS boost frequency from 30Hz ~ 70Hz.
5. COOLER: It cools the amplifier. Install in a cool place being careful to not obstruct the air vents.
6. OUTPUT CONNECTOR (SPEAKERS): MONO output of amplified signal for speakers connection. Check the minimum impedance and polarities before performing the installation.
7. POSITIVE POWER SUPPLY CONNECTOR: Connect to the positive battery terminal of the battery using a minimum 6 AWG cable with a fuse/circuit breaker installed as close to the battery as possible.
8. REMOTE CONNECTOR (REM): Allows automatic activation of the amplifier when turning on the radio/player. Connect to the remote output of the radio/player using a cable a minimum of 18 AWG.
9. NEGATIVE POWER SUPPLY CONNECTOR: Connect to the negative terminal of the battery using a cable with a minimum of 6 AWG.

Indicators LED

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:

Installation

Specification of the cables for proper installation:

• Power connectors (positive/negative) 6 AWG
• Remote connector 18 AWG
• Output signal connectors (speakers) 11 AWG
• Fuses or circuit breakers 70A
  The use of a fuse or circuit breaker is mandatory to protect the system from short circuits 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 make sure they are compatible with the equipment consumption.
  • Make sure that the battery is charged sufficiently for the product to operate.

• NO SOUND:

  • The cables to the speakers or RCA plugs may not be connected incorrectly or defective.
  • Make sure that the LEVEL control is not at a minimum.

• PROT LED FLASHING:

  • Make sure that the product’s air vents are not blocked and that the product is not overheating.
  • Speakers or cables are shorted. Check speakers, cables and connections.

• SOUND DISTORTIONS:
  The speakers may be overloaded or defective, lower the level and then readjust the level. This setting can be adjusted as follows:

  • On the radio/player, play 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%).
  • On the amplifier, begin with the LEVEL control at minimum, increase gradually until the LED CLIP starts to flash. Slowly decrease the LEVEL until the led goes out completely.

• WEAK OF BASS:
  Cables of the speakers may be reversed and (speakers out-of-phase).

• NOISE AND FAILURE IN SOUND:

  • Make sure that the installation is not close to the vehicle’s original wiring as it may cause interference and noise in the audio signal.
  • Create a separate power connection for the sound system. Use a fuse/ circuit breaker as close to the battery as possible for protection.
  • Make a good grounding for the amplifier. To do this, remove the paint from the vehicle chassis at the desired point. Attach the wire using a ground terminal. To prevent oxidation, isolate with paint.
  • Do not loop the ground. Avoid using multiple grounds. If possible, use a star connection, so all the grounds run from a single point.
