Benchmark System Calculator

Results update on input change.

Select DAC Calibration:

+24 dBu at 0 dBFS, XLR Input (Benchmark DAC)

4 Vrms at 0 dBFS, XLR Input (Typical HiFi Balanced)

2 Vrms at 0 dBFS, RCA Input (Typical HiFi Unbalanced)

Select AHB2 Amplifier Mode:

Stereo Bridged Mono

Enter LA4 Volume Setting: dB

Enter Speaker Sensitivity:

Value: 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

Amplifier Output Level: dB (relative to 2.83 V)

SPL from single loudspeaker: dB SPL (2.83 V, 1 meter)

Gain from multiple loudspeakers: dB

Loss due to distance: dB (relative to 1 meter)

Gain from room reflections: db (typical - may vary)

Results

Peak Output Level (at typical listening position): dB SPL

Amplifier Headroom (at Peak Output): dB

Amplifier Peak Output Power: Watts

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.
