The correct test tone frequency to use to set the sensitivity of a subwoofer amplifier depends on the frequency response of the signal going to the amp. If the installer has applied any equalization to the audio signal using the tone or loudness controls on the radio, through a digital signal processor or by the bass boost control on the amp, then the frequency …

An audio system with properly set gain structure should be loud, dynamic and free of distortion. Input sensitivity is adjustable on an amplifier or DSP due to the fact that the signal strength varies from the previous source’s outputs. If the input signal strength is too low the amplifier most likely won’t reach it’s maximum output.

With a high-sensitivity 110 dB speaker, the amplifier could deliver a sound pressure level of up to 130 dB (ignoring power compression). The power output of the AHB2 can be boosted by almost a factor of 4 by operating it as a fully-balanced monoblock amplifier (switch selectable). In mono mode, the AHB2 can deliver 380 W into 8 Ohms. This is 25.8 dB higher …

Well, I have read on audiokarma that you can calculate maximum power of your amplifier based on the input sensitivity of the amp and output of the component with the following formula: 20*log(V1/V2)=dB. V1=component output voltage V2=amp input sensitivity. So, my CD player output is 2000mV and the amp's input sensitiviy is 200mV. 20*log(2000/200)=20dB

There is not an audio industry standard. Most amps fall between 1 or 2 volts RMS for input sensitivity. This is dictated by a few design choices, one being noise. High gain will increase noise, so you don’t want to set the gain too high. Thank you. What tradeoffs do people generally make beyond reducing noise?

Lots of amps were designed with a small input sensitivity about like 0.6V, years ago. Newer amps will be higher, roughly 1V to 2V. You could add a couple of resistors at the preamp output for each channel to reduce the output for a given volume knob setting. For example, change the sensitivity to 1.2V instead of 0.6V.

Above is the voltage gain and input sensitivity specification for the QSC GX series professional power amplifiers. For those mathematically inclined, you can verify the numbers with the equation: Voltage Gain (Av) = 20 * Log (Vout/Vin)
What is "Input Sensitivity"? - inSync

Input Sensitivity controls are commonly found on amplifiers and other audio equipment. While they appear to function like any volume control, there is a distinction between the two. They are nearly the same functionally in that input sensitivity controls will change the volume or output of an amplifier.

Signal-to-noise ratio (SNR): To avoid audible hiss from the amplifier noise floor, SNR should typically exceed 90 dB in low-power amplifiers for portable applications, 100 dB for medium-power designs, and 110 dB for high-power designs.
