Always use shielded cable (shielding) for the connection of audio signals in order to avoid noise, hum and interference.
- Page 8 Connection The supply voltage is connected with the "power+” and “power-“ terminals. The supply voltage can vary between 6 and 15VDC and doesn't necessarily have to be regulated. Thanks to the wide voltage range, the circuit can operate on batteries, via a transformer (fig. 2.0) or via an adapter (fig.
