In the world of car audio, installing a subwoofer or amplifier requires a lot of work to ensure quality sound output. One important component in the process is installing a line output converter (LOC) to convert the high-level speaker signal into a low-level signal that the amplifier can work with. The SNI-35 LOC from PAC Audio is one of the best in the market, and in this article, we will discuss the wiring diagram for this amazing product.
What is an SNI-35 Line Output Converter?
The SNI-35 Line Output Converter is a device that is used in car audio systems to convert high-level signals from the speaker wires to low-level RCA jacks. The low-level signal is then sent to an amplifier for processing and amplification. The SNI-35 is designed to work with a wide range of audio systems, and it has a compact design that makes it easy to install.
How does the SNI-35 Line Output Converter work?
The SNI-35 Line Output Converter works by detecting the high-level audio signal coming from the speaker wires and then converting it to a low-level signal using a step-down transformer. The output from the transformer is then sent to the RCA jacks, which can be connected to an amplifier or other audio device.
The SNI-35 also has a ground loop isolation circuit, which helps to eliminate any noise or interference that may occur during the audio transfer process. This ensures that the audio output is of high quality and is free from any unwanted noise or distortion.
What are the benefits of using an SNI-35 Line Output Converter?
Using an SNI-35 Line Output Converter comes with several benefits, including:
- It allows for easy installation of an aftermarket amplifier or subwoofer
- It helps to maintain the quality of the audio signal
- It eliminates any noise or interference that may occur during the audio transfer process
- It is compatible with a wide range of audio systems
- It has a compact design that makes it easy to install
Wiring Diagram for SNI-35 Line Output Converter
The wiring diagram for the SNI-35 Line Output Converter is quite simple and straightforward. It involves connecting the wires from the LOC to the existing speaker wires and then connecting the RCA cables to the amplifier. Here is how to wire the SNI-35 LOC:
Step 1: Identify the speaker wires
The first step involves identifying the speaker wires in your car audio system. You can do this by checking the wiring diagram of your car or by using a wire tester to check for the speaker wires.
Step 2: Connect the wires from the LOC to the speaker wires
Once you have identified the speaker wires, you need to connect the wires from the SNI-35 LOC to them. Here is how to do it:
- Connect the white wire from the SNI-35 to the left positive speaker wire
- Connect the white/black wire from the SNI-35 to the left negative speaker wire
- Connect the gray wire from the SNI-35 to the right positive speaker wire
- Connect the gray/black wire from the SNI-35 to the right negative speaker wire
- Connect the blue wire from the SNI-35 to the remote turn-on wire of the amplifier
Step 3: Connect the RCA cables to the amplifier
Once you have connected the SNI-35 wires to the speaker wires, you need to connect the RCA cables to the amplifier. Here is how to do it:
- Connect the white RCA cable to the left input of the amplifier
- Connect the gray RCA cable to the right input of the amplifier
Step 4: Ground the SNI-35
The last step involves grounding the SNI-35. Here is how to do it:
- Connect the black wire from the SNI-35 to a metal chassis ground in your car
FAQ
What is a line output converter (LOC)?
A line output converter (LOC) is a device used to convert high-level audio signals to low-level audio signals. This is necessary when installing an aftermarket amplifier or subwoofer in a car audio system that does not have preamp outputs.
What is the difference between a high-level and low-level audio signal?
A high-level audio signal is the signal that comes from the speaker wires and is typically at a higher voltage level than a low-level audio signal. A low-level audio signal is the signal that comes from the RCA jacks and is at a lower voltage level than a high-level audio signal.
What is ground loop isolation?
Ground loop isolation is a circuit that helps to eliminate any noise or interference that may occur when audio signals travel through different ground points in a car audio system. It ensures that the audio output is of high quality and is free from any unwanted noise or distortion.
Can the SNI-35 Line Output Converter be used with any audio system?
Yes, the SNI-35 Line Output Converter is designed to work with a wide range of audio systems and is compatible with most aftermarket amplifiers and subwoofers.
Is the SNI-35 Line Output Converter easy to install?
Yes, the SNI-35 Line Output Converter has a compact design that makes it easy to install. It comes with a wiring diagram and instructions that make the installation process simple and straightforward.
What are the benefits of using an aftermarket amplifier or subwoofer in a car audio system?
Using an aftermarket amplifier or subwoofer in a car audio system can help to improve the sound quality and overall performance of the system. It allows for greater control over the audio output and can provide a more powerful and dynamic sound.
