AHB2 POWER and SPL OUTPUT CALCULATOR
Enter Input Level: dBu Vrms	Select Amplifier Sensitivity: +22 dBu (Gain = 9.25 dB) 4 Vrms (Gain = 17 dB) 2 Vrms (Gain = 23 dB)
Select Amplifier Mode: Stereo Bridged Mono	Enter Speaker Sensitivity: dB SPL (2.83 V, 1 Meter) dB SPL (1 Watt, 1 Meter)
Select Speaker Impedance: 4 Ohms 8 Ohms	Enter Distance from Speaker(s): Meters
Select Number of Speakers: One Speaker Two Speakers	Select Room Configuration: Anechoic Chamber or Large Open Space Typical Listening Room Speakers mounted on or in front wall

CONTRIBUTING FACTORS
Gain from amplifier: dB (relative to 2.83 V)
SPL from single loudspeaker: dB SPL
Gain from multiple loudspeakers: dB
Loss due to distance: dB (relative to 1 meter)
Gain from room reflections: dB (typical - may vary)
RESULTS
SPL at Listening Position: dB SPL
Amplifier Output Power: Watts
Amplifier Headroom: dB

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, then hit "Calculate").

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.
