How to set Gain and VCL of Sanway FP10000Q and FP14000 power amplifier

When you using a amplifier, you may want to use a bigger power wattage amplifier to drive a speaker with smaller power. What should we do?


Today, we are going to introduce the function of Gain and VCL in the rear panel of power amplifier, so that you could get different output power and input sensitivity from different settings.


Firstly, you should know the stereo power of your amplifier. Take the FP10000Q and FP14000 as a example.

 FP10000Q is a 4x1350W at 8ohms, 4x2100W at 4ohms, 4x2500W at 2ohms 4CH power amplifier

FP14000 is a 2x2350W at 8ohms, 2x4400W at 4ohms, 4x7000W at 2ohms 2CH power amplifier.


The Function of Gain 


The following features maybe adjusted using the DIP switches on the rear - panel of  the amplifier. Gain- Globally set for all channels, from +23 dB to +44 dB in 3 dB steps. Bridge 1+2 and 3+4 Switches the channel pairs into bridge mode operation an automatic -6 dB gain compensation is applied.


The following schematics illustrate how the adjustable Gain circuitry affect input sensitivity:
