When it comes to amplifiers, there are numerous technical terms and abbreviations that can be confusing for those who are new to the world of audio equipment. One such term that often raises questions is “REM” on an amplifier. In this article, we will delve into the world of amplifiers and explore what REM means, its significance, and how it affects the overall performance of an amplifier.
Understanding REM on an Amplifier
REM stands for “Remote Enable Master” or “Remote Enable Mode.” It is a feature found on some amplifiers, particularly those designed for car audio systems or home theaters. The REM terminal is usually a small pin or connector on the amplifier that allows it to be turned on or off remotely using a separate device or switch.
How REM Works
The REM feature works by allowing a remote device, such as a head unit or a separate switch, to send a signal to the amplifier to turn it on or off. This signal is usually a low-voltage DC signal that is sent through the REM terminal. When the amplifier receives this signal, it will either turn on or off, depending on the state of the signal.
For example, if the head unit is turned on and sends a 12V DC signal to the amplifier’s REM terminal, the amplifier will turn on. Conversely, if the head unit is turned off and sends a 0V DC signal to the REM terminal, the amplifier will turn off.
Benefits of REM
The REM feature offers several benefits, including:
- Convenience: With REM, you can turn your amplifier on or off from a remote location, eliminating the need to physically access the amplifier.
- Simplified Installation: REM allows you to install your amplifier in a location that is not easily accessible, such as in the trunk of a car or behind a wall.
- Reduced Noise: By allowing you to turn your amplifier off when not in use, REM can help reduce noise and interference in your audio system.
Types of REM Terminals
There are two main types of REM terminals found on amplifiers: positive (+) and negative (-).
Positive REM Terminal
A positive REM terminal is the most common type of REM terminal found on amplifiers. It requires a positive voltage signal (usually 12V DC) to turn the amplifier on. When the signal is removed, the amplifier will turn off.
Negative REM Terminal
A negative REM terminal, on the other hand, requires a negative voltage signal (usually 0V DC) to turn the amplifier on. When the signal is removed, the amplifier will turn off.
Configuring REM on an Amplifier
Configuring REM on an amplifier is a relatively straightforward process. Here are the general steps:
- Identify the REM terminal on your amplifier. It is usually labeled as “REM” or “Remote Enable.”
- Connect the REM terminal to a remote device, such as a head unit or a separate switch.
- Set the remote device to send the correct voltage signal to the REM terminal. For example, if your amplifier has a positive REM terminal, you will need to set the remote device to send a 12V DC signal.
- Test the REM feature to ensure it is working correctly.
Troubleshooting REM Issues
If you are experiencing issues with your REM feature, here are some troubleshooting steps to follow:
- Check the REM terminal connection to ensure it is secure and not loose.
- Verify that the remote device is sending the correct voltage signal to the REM terminal.
- Check the amplifier’s settings to ensure that the REM feature is enabled.
REM vs. Other Remote Turn-On Methods
REM is not the only method of remotely turning on an amplifier. Other methods include:
-
DC Offset
DC offset is a method of remotely turning on an amplifier by applying a DC voltage to the amplifier’s input terminals. This method is less common than REM and requires a separate DC offset adapter.
-
Signal Sensing
Signal sensing is a method of remotely turning on an amplifier by detecting the presence of an audio signal. This method is often used in home theaters and requires a separate signal sensing module.
Conclusion
In conclusion, REM is a convenient feature found on some amplifiers that allows for remote turn-on and turn-off. By understanding how REM works and how to configure it, you can simplify your amplifier installation and reduce noise in your audio system. Whether you are a car audio enthusiast or a home theater buff, REM is a feature worth exploring.
| REM Terminal Type | Voltage Signal Required | Amplifier State |
|---|---|---|
| Positive (+) | 12V DC | Turns amplifier on |
| Negative (-) | 0V DC | Turns amplifier on |
By following the guidelines outlined in this article, you can unlock the full potential of your amplifier’s REM feature and take your audio system to the next level.
What is REM on an amplifier and how does it work?
REM on an amplifier stands for Rear Effect Mix, which is a feature that allows you to control the level of the rear surround sound speakers in a home theater system. It works by allowing you to adjust the mix of the audio signal that is sent to the rear speakers, creating a more immersive audio experience.
When you adjust the REM level, you are essentially controlling the balance between the front and rear speakers. By increasing the REM level, you are sending more of the audio signal to the rear speakers, creating a more enveloping sound field. Conversely, decreasing the REM level reduces the amount of audio signal sent to the rear speakers, resulting in a more focused sound.
What is the difference between REM and other surround sound formats?
REM is a proprietary surround sound format developed by Onkyo, a well-known audio equipment manufacturer. While it is similar to other surround sound formats such as Dolby Pro Logic and DTS Neo:6, REM is unique in that it allows for more precise control over the rear surround sound speakers.
In contrast to other surround sound formats, REM is designed to work specifically with Onkyo amplifiers and receivers. This means that REM is optimized to take advantage of the unique features and capabilities of Onkyo’s audio equipment, resulting in a more immersive and engaging audio experience.
How do I set up REM on my amplifier?
To set up REM on your amplifier, you will need to access the amplifier’s menu system and navigate to the surround sound settings. From there, you can select the REM mode and adjust the REM level to your liking.
It’s also important to ensure that your amplifier is properly connected to your rear surround sound speakers. This typically involves connecting the speakers to the amplifier’s rear surround sound outputs, and then configuring the amplifier to recognize the speakers as part of the surround sound system.
Can I use REM with any type of audio source?
REM can be used with a variety of audio sources, including DVDs, Blu-ray discs, and video games. However, the effectiveness of REM may vary depending on the specific audio source and the type of audio encoding used.
In general, REM works best with audio sources that are encoded in a surround sound format, such as Dolby Digital or DTS. This is because these formats are designed to take advantage of the surround sound capabilities of the amplifier and speakers.
How does REM affect the overall sound quality of my system?
REM can have a significant impact on the overall sound quality of your system, particularly in terms of the surround sound experience. By allowing you to adjust the level of the rear surround sound speakers, REM can help to create a more immersive and engaging audio experience.
However, it’s also possible to overdo it with REM, resulting in an unbalanced sound that is overly dominated by the rear speakers. To avoid this, it’s a good idea to experiment with different REM levels and find the setting that works best for your specific system and listening preferences.
Can I use REM with other surround sound formats?
Yes, REM can be used in conjunction with other surround sound formats, such as Dolby Pro Logic and DTS Neo:6. In fact, many Onkyo amplifiers and receivers allow you to combine REM with other surround sound formats to create a more customized audio experience.
When using REM with other surround sound formats, it’s generally a good idea to start with a lower REM level and adjust to taste. This will help to ensure that the surround sound experience is balanced and immersive, without overpowering the front speakers.
Is REM a proprietary feature of Onkyo amplifiers?
Yes, REM is a proprietary feature of Onkyo amplifiers and receivers. This means that REM is only available on Onkyo audio equipment, and is not compatible with amplifiers and receivers from other manufacturers.
While this may limit the availability of REM, it also means that Onkyo has been able to optimize the feature specifically for their own equipment, resulting in a more seamless and effective surround sound experience.
