When it comes to car audio systems, amplifiers play a crucial role in delivering high-quality sound to your speakers. One of the key features of car amplifiers is the REM (Remote Turn-On) or Remote Gain Control, which allows you to adjust the amplifier’s gain from a remote location. In this article, we will delve into the world of REM on car amplifiers, exploring its definition, benefits, and how it works.
What is REM on a Car Amplifier?
REM, or Remote Turn-On, is a feature found on many car amplifiers that allows you to turn the amplifier on and off remotely. This feature is usually controlled by a wire that connects the amplifier to the car’s head unit or a separate remote control. The REM wire is typically a low-voltage wire that carries a signal from the head unit to the amplifier, telling it when to turn on and off.
How Does REM Work?
The REM feature works by using a low-voltage signal to trigger the amplifier’s turn-on circuit. When the head unit is turned on, it sends a low-voltage signal (usually around 12V) to the amplifier through the REM wire. This signal tells the amplifier to turn on and start amplifying the audio signal. When the head unit is turned off, the signal is removed, and the amplifier turns off.
Benefits of REM on Car Amplifiers
The REM feature offers several benefits to car audio enthusiasts. Some of the key benefits include:
- Convenience: With REM, you can turn the amplifier on and off from the comfort of your driver’s seat. This eliminates the need to physically access the amplifier, which can be located in a hard-to-reach area of the car.
- Improved Safety: REM allows you to turn off the amplifier when you’re not using it, which can help prevent overheating and reduce the risk of electrical fires.
- Reduced Noise: When the amplifier is turned off, it eliminates any background noise or hiss that may be present when the amplifier is on.
Types of REM Controls
There are two main types of REM controls: wired and wireless.
- Wired REM: This type of REM control uses a physical wire to connect the amplifier to the head unit or a separate remote control. Wired REM is the most common type of REM control and is usually more reliable than wireless REM.
- Wireless REM: This type of REM control uses a wireless signal to communicate between the amplifier and the remote control. Wireless REM is more convenient than wired REM, but it can be more prone to interference and signal loss.
