Another might label the control going from 0 to 100.Ī little bit of history helps to explain how the concept of 0 dB and its negative and positive values migrated from the professional broadcasting and recording environment to consumer audio gear. For example, one manufacturer might rate his volume control from 1 to 10, “1” being minimum volume and “10” being the maximum. So whatever one manufacturer chose to put on the front-panel volume control or display applied only to that particular receiver. The confusion occurs because we’ve grown up comprehending that bigger numbers mean larger values or an increase.Īfter reading this article, however, I think that you'll find the relative values of negative speaker level dB settings are actually logical, because in the old days, the settings on AV receiver volume controls were entirely arbitrary and unrelated to actual dB values. In fact, it seems counter-intuitive: As you reduce the playback loudness on your AV receiver, the negative numbers grow larger, and when you exceed the “0 dB” mark as you crank up your AV receiver’s volume to extremely loud levels and possible distortion, the positive numbers are tiny: +3 dB, +6 dB, and so on. Loud equals big numbers soft equals small ones.On current AV receiver/preamps, it’s the negative values of dB loudness settings that are confusing.
It was simple, logical, and easy for anyone to understand. Previously, if a volume control had numerical values marked on the receiver’s front panel or shown in a front-panel display, the numbers got bigger as you increased playback volume when you reduced the volume, the numbers got smaller.

Negative numbers mystery solved! The AVENTAGE line of high-performance AV receivers are designed to provide full-bodied audio for movie sound effects and the accurate reproduction of music sources.It’s only in the last decade that the concept of “0 dB” as it relates to AV receiver volume controls and playback loudness has become common on AV receivers and AV preamps. For example, if your receiver reads “-25 dB” it means that the volume of the signal has been attenuated by 25 dB (that is, made 25 dB quieter than the loudest it could possibly be) before being output to your speakers. So how does this correlate to your AV receiver’s volume control settings? Understanding the “0 dB” SettingĪs counterintuitive as the negative numbers setting may appear, the Yamaha volume control is actually more accurate than most volume dials. As you know, decibel is the unit used to measure the intensity of a sound. You also likely noticed the “0 dB” (decibel) setting on the volume panel display. In addition to the amp and attenuator, every single part in an AV receiver affects sound quality, such as the high grade parts used in Yamaha units pictured above (L to R): custom made block capacitors, extra-large power transformer, schottky barrier diode, large size speaker terminals and high quality parts. The negative number scale is a more accurate way to indicate the volume output. When you turn up the volume of an amp you are actually decreasing the amount of restriction placed on that amp and in turn it plays louder.

This is an electronic circuit that acts as a volume control by restricting the amp from playing at full volume and/or power. The only way to control the output is to add or connect a volume control. It would play at full power all the time. Now imagine an amp with no volume control. For example, when you plug your BluRay™ player into your receiver, the player sends a signal into your receiver’s amp and then to the speakers. The numbers on the receiver’s volume represent the amplification factor on the signal coming in. Once you get a handle on the explanation, it makes sense. What does that mean? Negative numbers show the amount of attenuation that the volume control is applying to the amplifier. Then you notice the numbers on the volume control display are negative. So, you’ve made your choice – a Yamaha AV receiver from the highly rated AVENTAGE line – and got it all set up.
You’ve invested a lot into your top-of-the-line receiver: the post-dinner evenings spent on the computer researching competing models the lunch break trips to the local brick-and-mortar electronics store to test out your top three options and of course, the time it took to convince your skeptical significant other that your decade-old receiver simply had to be replaced – even it if may have had a few years left in it.
