Sound Effect

 Skema Sound Effect

This circuit uses a UM3561 IC to produce four different sound effects.
UM3561 IC Sound Effect Generator Circuit
                               Notes
Nothing too complicated here. The IC produces all the sound effects, the output at Pin 3
being amplified by the transistor. A 64 ohm loudspeaker can be substituted in place of
the 56 ohm resistor and 8 ohm loudspeaker. The 2 pole 4 way switch controls the sound
effects. Position 1 (as drawn) being a Police siren, position 2 is a fire engine sound,
3 is an ambulance and position 4 is a machine gun effect. The IC is manufactured by UMC
and was available from Maplin electronics code UJ45Y. At the time of writing this has
now been discontinued, but they have have limited stocks available.
UM3561 Availability
The IC sound generator UM3561 is now available in a kt from Maplin Electronics. Click

SKEMA RANGKAIAN EQUALIZER 5 BAND
 
In this part of the investigation in a series of 5-band Equalizer circuits with a single IC BA3812 namely L, a device used in the hi-fi.IC BA 3812 This is L IC with 5-point Equalizer with all the functions integrated in one IC. To get a clear picture of the circuit is a series of pictures, click on it.
To Equalizer has advantages, namely: small distortion, a small noise, dinamic local area, and is suitable for a series of hi-fi stereo. And with a wide voltage range from 3.5 volt to 16 volt.voltage is the recommended 8 volt but according in market 9volt highest voltage and 16 volt adl.
