 ;
perfect! you just sent to me the copy in Italian witout even my specification!!!! so you are really smart cooperative and efficient. To my opinion the best place all over to get a manual of electronics!!!!
;
Well Well Well!!!! Good manual perfect for my hobby!!! As Before you have done a very well done work!!!! Thank you
;
Super nice! Good to have a manual in digital format.
;
Great job supplying the manual.
Many of these products weerepretty obscure, so it was great that you had
the manual for it!
;
Great manual, would not have been able to operate my machine without it!!

The directivity index (DI) of the H9500 horn is shown in Figure 5. The smoothly rising DI is a consequence of the gradual narrowing of the vertical dispersion angle above 2 kHz and contributes to the overall flatness of the high-frequency response of the system.

Overall system on-axis pressure response and impedance are shown in Figure 6. The contributions of the paralleled lowfrequency sections and the high-frequency section are shown individually along with their acoustical summation. The overall slopes in the crossover region are a combination of electrical (network) and acoustical response.

The second and third harmonic distortion of the system is shown in Figure 7. Here, the system is driven with sine wave input to produce an output of 96 dB Lp at a distance of 1 meter. An output of 96 dB with a sine wave input corresponds to extremely high system output with wide band program material. Distortion curves have been raised 20 dB, and the values seen here lie well below 1% for the lowest frequencies up to 4.5 khz, reaching a value of only 1.6% at 10 kHz. Not many loudspeakers can demonstrate such low levels of distortion as shown here.
