THE DESIGN OF ACTIVE CROSSOVERS

Chapter 4: p112, there is a reference to "the very clever NTM crossover in Chapter 6". It is actually in Chapter 5.

Chapter 6: p129, at the end of the second whole paragraph, "accurately" is mis-spelled as "accutrately".
How that got through multiple layers of spell-checking we may never know...

Chapter 6: p135, Figure 6.9, the Linkwitz Riley filter for the mid path should be labelled "5.12 kHz" not "512 kHz".

Chapter 8: p197, Equation 8.7: ignore floating comma at the end

Chapter 8: p204, first line should say Figure 8.5c not 8.4c.

Chapter 8: p225, 3rd paragraph, 3rd from last line: ... response is now down only -5.6dB at 100 Hz; should be 100 kHz.

Chapter 8: p240, Figure 8.37b, the 104 nF capacitor should be labelled "C2" not "C1".

Chapter 9: p257, R7 in Fig 9.5c should be labelled R4.

Chapter 11: p306, first line of second para should read "Constant Directivity Horn Equalisation".
I'm sure you guessed that one.

Chapter 13: p380, 2nd line in 2nd paragraph should read 0.0035% not 0.0015%.

Chapter 13: p402, penultimate line in 1st paragraph of section 13.15, LM47910 should read LME47910.

Chapter 19: p535, Figure 19.1, caption should have the word "subtractive" deleted. It is not a subtractive crossover.
The two blocks labelled "second-order allpass" should be labelled "third-order allpass"

My apologies for these shortcomings. The mistakes are mine and not my publisher's.
