Benchmark System Calculators
Calculate the combined system performance of a Benchmark audio system using a DAC3 D/A converter, LA4 line amplifier, and AHB2 power amplifier driving your speakers.
Determine the output level and amplifier headroom of an AHB2 when driving your speakers in your listening room.
Determine the output level and amplifier headroom of an HPA4 driving your favorite headphones.
Unit Conversion Calculators
Calculate gain based on an input and output voltage. Calculate output voltage based on the gain and an input voltage.
Convert THD percent to and from dB.
Convert Volts RMS to and from dBu.
Convert Watts to and from Decibel-Watts.
Determine your speaker output SPL based on the amplifier power and the speaker sensitivity. Includes system noise calculations.
