Behringer A500 Measurements

A local customer of mine brought over their Behringer A500 (Professional 600 Watt Reference-Class Studio Power Amplifier). I took some measurements of it and posting up for the community.

All the measurements below are with the amplifier operating in stereo mode with an 8-ohm load on each channel. RCA inputs were used as XLR inputs actually yielded worse results.

Bench mode (with both channels on the same gain setting there is a 0.3dB difference between channels)

Signal-to-Noise Ration (SNR), no weighting

Distortion (THD+N) vs Measured level at 1kHz (Starkrimson Ultra show for comparison)

Distortion (THD+N) vs Frequency at 10W output (Starkrimson Ultra show for comparison)

Intermodulation (IMD) Distoriton vs power level (starkrimson ultra show for comparison)

Wideband FFT with no input

Multitone

Frequency Response

Reference-Class Studio Power Amplifier. More like pink noise generator.

I certainly would reference back to it, to see how much better my amps doing.

Fix the channel imbalance and that amp is probably not audible vs a much better measuring one on music. Assuming none of the noise is high enough to hear.

Adding Starkrimson ultra wideband FFT for comparison.
