A Tone Stack Calculator is an essential tool for anyone involved in creating, adjusting, or maintaining audio equipment. But what exactly is this calculator and how does it function? Let’s find out.
Definition
A Tone Stack Calculator is a software or digital tool, often embedded within websites, used to calculate the frequency response of an audio amplifier’s tone stack. A tone stack is an essential part of an amplifier, responsible for shaping the tonal characteristics of the output signal.
How Does a Tone Stack Calculator Work?
The calculator uses a specific formula – usually associated with the Baxandall tone stack to determine the output voltage based on various inputs. These inputs include input voltage, resistance, and capacitance values. The user can anticipate how changes will affect the frequency response by tweaking these values.
The Underlying Formula
The Calculator relies on a mathematical formula:
Vout = Vin * ((R1/Ri) * (1 + (R3/R2)) * (1/(1 + (R4/R3))) * (1/(1 + (1/(R5C5)(R4/R3))))
Here, Vin
is the input voltage, Vout
is the output voltage, R1
, R2
, R3
, R4
, and R5
are resistance values, C5
is the capacitance value, and Ri
is the input resistance. This formula represents the inherent interaction within a tone stack circuit.
An Example
Let’s say you have the following values: Vin=2V
, R1=10kΩ
, R2=22kΩ
, R3=47kΩ
, R4=33kΩ
, R5=100kΩ
, C5=10nF
, and Ri=220kΩ
. Plugging these values into the calculator will yield the amplifier’s output voltage and adjusted frequency response.
