CONTINUOUS AVERAGE OUTPUT POWER

< 0.0003 % THD+N at full rated power, 20 Hz to 20 kHz

  • 100 Watts per channel into 8 Ohms, both channels driven
  • 130 Watts per channel into 6 Ohms, both channels driven
  • 190 Watts per channel into 4 Ohms, both channels driven
  • 240 Watts per channel into 3 Ohms, both channels driven
  • 200 Watts into 16 Ohms, bridged mono
  • 380 Watts into 8 Ohms, bridged mono
  • 480 Watts into 6 Ohms, bridged mono

All speakers have variations in input impedance. Select loads based on nominal impedances not minimum impedances. The AHB2 is stable into all loads. The AHB2 is conservatively rated at an output level where THD+N is < 0.0003 % instead of the more typical 1% THD+N. Power at 1% THD will be higher.

OUTPUT VOLTAGE INTO VARIOUS LOAD IMPEDANCES

< 0.0003 % THD+N at the following output voltages and load impedances, 20 Hz to 20 kHz

  • 29.03 dBV, 31.25 dBu, 28.28 Vrms into 8 Ohms, both channels driven
  • 28.92 dBV, 31.14 dBu, 27.93 Vrms into 6 Ohms, both channels driven
  • 28.81 dBV, 31.03 dBu, 27.57 Vrms into 4 Ohms, both channels driven
  • 28.57 dBV, 30.79 dBu, 26.83 Vrms into 3 Ohms, both channels driven
  • 27.14 dBV, 29.36 dBu, 22.76 Vrms into 2 Ohms, both channels driven
  • 35.05 dBV, 37.27 dBu, 56.57 Vrms into 16 Ohms, bridged mono
  • 34.83 dBV, 37.05 dBu, 55.14 Vrms into 8 Ohms, bridged mono
  • 34.59 dBV, 36.81 dBu, 53.67 Vrms into 6 Ohms, bridged mono
  • 33.16 dBV, 35.38 dBu, 45.52 Vrms into 4 Ohms, bridged mono

Use dBV to calculate the peak SPL from your speaker/amplifier combination. Use the following formula: Amplifier output voltage in dBV + speaker sensitivity at 2.83V - 9 dB. Example: (29.03 dBV at 8 Ohms) + (90 dB SPL @ 2.83V 1m) - 9 dB = 110 dB SPL at 1 meter

SNR & DYNAMIC RANGE

Rated output relative to output noise, inputs shorted

  • 132 dB A-weighted, Stereo Mode
  • 135 dB A-weighted, Mono Mode
  • 130 dB Unweighted, 20 Hz to 20 kHz, Stereo Mode
  • 133 dB Unweighted, 20 Hz to 20 kHz, Mono Mode

NOISE VOLTAGE

Output noise voltage, A-weighted, inputs shorted

-103 dBV, -101 dBu, 7.1 uVrms, Stereo Mode

-100 dBV, -98 dBu, 9.8 uVrms, Mono Mode

Use dBV to calculate the SPL of the noise produced by your speaker/amplifier combination. Use the following formula: Amplifier output noise voltage in dBV + speaker sensitivity at 2.83V - 9 dB. Example: Mono mode driving very high efficiency speakers: (-100 dBV) + (104 dB SPL @ 2.83V 1m) - 9 dB = -5 dB SPL at 1 meter. This means that the system noise will be 5 dB below the threshold of hearing when driving speakers with a very high 104 dB efficiency.

NOISE RELATIVE TO 2.83 VRMS

Output noise relative to 2.83 Vrms, A-weighted, inputs shorted

-112 dB, Stereo Mode

-109 dB, Mono Mode
