Vera Audio P400/1000 Power Amplifier










 
See datasheet under downloads for measurements.

Some key performance data are:

- Selectable gain in very accurate 3dB steps from 12dB to 30dB as well as mute function
- CMRR of at least 89dB@100Hz and better than 89dB@1kHz (measured based on the IEC 60268-3 standard)
- Very low noise of less than 15uV
- S/N of more than 130dB (stereo)
- S/N of more than 132dB (bridged)

Continuous power:
- Stereo, both channels driven at 8 ohms:
- 400W with maximum 1% THD+N
- 330W with maximum 0.01% THD+N
- 300W with maximum 0.004% THD+N

Stereo, both channels driven at 4 ohms:
- 750W with maximum 1% THD+N
- 620W with maximum 0.01% THD+N
- 550W with maximum 0.004% THD+N

Bridged, driven at 8 ohms:
- 1500W with maximum 1% THD+N
- 1100W with maximum 0.01% THD+N
- 800W with maximum 0.004% THD+N

DIMENSION AND WEIGHT:
Width: 29 cm
Depth (including terminals): 38 cm
Height: 8.2 cm

Weight: 9 kg

The calculations below show the power output vs impedance in stereo mode and in bridged mode. Take note that these are not measurements but they should be very close to actual performance.



If the speaker has an impedance that drops below approximately 3.6 Ohm, bridging will become futile in regards to power output compared to stereo mode.
