The default settings show the stereo output into 8 Ohms.

Select "Bridged Mono" and "4 Ohms" to see the maximum 4-Ohm bridged-mono output power for the AHB2. This maximum output power will be achieved at an input level of 20.1 dBu (reduce the input level by entering 20.1).

Note: If the input parameters would cause clipping, the results show the maximum un-clipped output, and the "Amplifier Headroom" window will read "Amplifier Clipping!". When this occurs, reduce the "Input Level" to achieve an "Amplifier Headroom" of 0 dB.

Click "Read Full Post" for an advanced calculator which calculates SPL at the listening position when using an AHB2 power amplifier.
