1200
DIGITAL AMPLIFIER
USER MANUAL

Introduction

Thank you so much for choosing a Stetson 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 a “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

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:
▪ HIGH PASS FILTER (H.P.F.): This variable control allows you to select the initial frequency from 10Hz to 90Hz that will be reproduced by the amplifier.
▪ LOW PASS FILTER (L.P.F.): This variable control allows you to select the final frequency from 90Hz to 15KHz that will be reproduced by the amplifier.
BASS BOOST:
▪ BASS: Variable control for bass boost from 0dB to +10dB.
▪ FREQ: Variable control for BASS boost action from 30Hz to 70Hz.
4.1. MID BASS BOOST: Variable control from 0dB to +10dB with a bass boost at 270Hz.
4.2 MID HIGH BOOST: Variable control from 0dB to +10dB with acting on boosting midrange at 2KHz frequency.
COOLER: It provides cooling of the amplifier. Install in a cool place without the obstruction of air inlets and outlets.
FLAT KEY: 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 model.
Power input
OUTPUT CONNECTOR (SPEAKERS): MONO output of amplified signal for speakers connection. Check the minimum impedance and polarities before performing the installation.
POSITIVE POWER SUPPLY CONNECTOR: Connect to the positive battery terminal through a minimum 6 AWG cable with a fuse/circuit breaker (70A) as close to the battery as possible.
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.
NEGATIVE POWER SUPPLY CONNECTOR: Connect to the negative terminal of the battery using a cable minimum of 6 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

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
32°F, audio is stopped and the coolers run at maximum speed to speed up the
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 the voltage of the battery or power supply.
| Diagnostic: Supply voltage greater than 16V.
Solution: Check the voltage of the battery or power supply.

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 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.

Any updates made in this manual will be available for customers to consult without any charge on the brand’s site.
It is recommended that the updated manual be consulted whenever needed.
