At the cottage window a little bird sang.
And the light of the window did flicker.
And look. The roof up it sprang and the cottage became a house bigger.
Look. Into a world the cottage grew and the vast and wide too and filled with song was the air and like new was the sun's flare.

By driving a loudspeaker's voice-coil directly from the output of a dedicated power amplifier, a designer can avoid many of the problems that occur in passive speakers due to the impedance mismatches among the…

I used DRA Labs' MLSSA system, a calibrated DPA 4006 microphone, and an Earthworks microphone preamplifier to measure the Genelec G Three's frequency response in the farfield. I used an Earthworks QTC-40 mike for the nearfield responses.
Genelec specifies the G Three's input impedance as 10k ohms. As this is an active loudspeaker, I calculated the input impedance by using spot frequency tones generated by my Audio Precision SYS2722 and examining how the nearfield sound pressure level dropped when I increased the source impedance to 600 ohms from 20 ohms (…
The cover art for Wilco's finely hewn double album Cruel Country resembles a hand-stitched doily or the kind of patch you might have seen sewn onto the back pocket of a pair of vintage faded jeans circa 1978. It's appropriate: Wilco's music has long been a patchwork, piecing together the scope and potential of American music for the band's nearly 30 years.
Cruel Country, Wilco's latest, is anything but…

I measured the first sample of the WiiM Mini with my Audio Precision SYS2722 system, repeating some tests with the second sample. Looking first at the WiiM's analog inputs and outputs, the input impedance was a usefully high 32k ohms at 20Hz and 1kHz, 13k ohms at 20kHz. The analog output preserved absolute polarity (ie, it was noninverting), and the source impedance was a low 33 ohms from 20Hz to 20kHz. The gain was 0.37dB with the fixed gain set to "1V." With the fixed gain set to "2V (Loud)," the gain was 5.8dB at the outputs; that is, an input of 1V resulted in…
