I needed an attenuator to reduce the output of our sound board to mike level for our video camera. I am using this along with a second 35 dB attenuator with good results. I will probably buy a second pair of 20 dB to use with the 40 dB pair for a better match.

2022-2-2 · The voltage ratio must be derived from the attenuation in decibels. Power ratios expressed as decibels are additive. For example, a 10 dB attenuator followed by a 6 dB attenuator provides 16dB of attenuation overall. 10 dB + 6 db = 16 dB. Changing sound levels are perceptible roughly proportional to the logarithm of the power ratio (PI / PO).

2017-2-12 · 40 dB = hundred times the voltage: If we consider audio engineering, we are usually not interested in power. Do not ask what power amplification means. Leave that to the telephone companies or the transmitting aerials (antennas). Power gain is really not used in …
Homemade RCA Attenuator : 5 Steps (with Pictures ...
https://www.instructables.com/Homemade-RCA-Attenuator/
This project arose from the fact that I had too much gain in my audio system, and I needed a practical solution without modifying the PCB circuit. The problem can be solved using an RCA (in-line) attenuator, but since a new one can be quite expensive, around 30-40 € or even more, so I decided to make one by myself.

2021-6-9 · Long coax cable: Loss 3 dB attenuation (reduction to half the level) High power 10 watt amplifier: Gain=30 dB (increase in signal level by a factor of 1000 times. Note the 3 zeros = 30 dB) Calculation: Output = -30 + 16 -10 - 3 + 30 = 3 dBW = 2 watts. Comment: This should work, but note that if the adjustable attenuator were to be turned to its ...

The attenuator resistor values in the table are given for a 50 ohm system as this is the most likely impedance system required. However it is recognised that other impedance systems may also be used. To convert the values in the table to another value of impedance, they should be multiplied by the factor Z / 50, where Z is the characteristic ...

2017-2-12 · Amplifier Conversion - Gain / Loss Gain means signal strength or amplification.In audio we use only voltage amplification. Forget the power. The amplification factor, also called gain, is the extent to which an active device boosts the strength of a signal.
