Tactile Sound
Amplifier
I bought the 70W amplifier from Conrad Electronic.
Was not cheap but works perfect for me. If you plan
to build a similar system you should think about a
little bit more powerful amplifier. As I mentioned
it works perfect, but in some situations it would be
nice to have extra power available, e.g. with the
landing bump.
70W mono amplifier and dedicated power
supply.
The input of the amplifier is fed by the output of the sound mixer. The level of the input signal is adjusted with the sum control of the audio mixer.
Power Supply for Amplifier
The amplifier gets the 12V
operating voltage from a dedicated power supply.
This was necessary in order to avoid voltage drops
on the common 12V power supply with high bass loads.
