Whether it is possible to change how the volume on a receiver is shown or not depends entirely on what your particular receiver allows. Whatever the reason, some wonder if it’s possible to change a receiver’s volume scale to positive numbers. Maybe you’re having trouble explaining to your children or guests why the volume is in negative numbers, or you think it’s less aesthetically pleasing than a traditional numeric scale. Can I Change My Receiver’s Volume To Positive Numbers?Īlthough there is no way to change the way the receiver works functionally, some people don’t like having negative numbers about their volume level. Without this capability, your speakers would constantly play audio at the maximum volume. Turning the receiver’s volume knob or attenuator will reduce or increase this volume by increasing or decreasing the strength of the signal the device sends. When hooked up to a receiver, these devices output audio at a consistent volume. There are many devices you may have hooked up to your receiver and, in turn, your home’s speaker system. As mentioned above, the volume knob on a receiver acts as an attenuator or reduces the strength of the audio signal coming from your device. In terms of volume, attenuation can be defined as the reduction in the strength of a signal. The volume control knob on your receiver is called an “attenuator.” What Is Attenuation?

Instead, you’re reducing or increasing the volume restriction the receiver allows.įor example, you may see the volume noted on your TV or receiver as “-40 dB.” This means the receiver tells your speakers to play the audio at 40 dB, or decibels, less than the maximum volume. When you turn the volume up or down, you’re not actually changing how loud the device plays audio.

Without this volume control feature, the sound would always play at full volume. Receivers help control the volume of the audio signal sent from your device. When you plug a device, whether a TV, console, or Bluray player, into a receiver, the device sends a signal to the receiver, and the receiver sends it to your speakers. Instead of reflecting the actual volume of your speakers, these numbers represent the amplification factor. The reason you see negative numbers concerning volume is because of the way certain receivers work. Surprisingly, this is not an error on your TV or receiver. Instead of a traditional numerical scale, you see a negative number followed by the abbreviation “dB.” But, when you turn the volume knob or press the corresponding button on your remote, you notice that the numbers look a little weird. You purchased a new receiver for your TV’s surround system and hooked up all the necessary components.
