مفتاح ضبط الصوت الآلي يتحكم في ضبط صوت راديو السياره

The volume control is intended primarily for insertion between a car radio and its booster. It automatically
adapts the volume to the amount of road and engine noise. This is done in four 5 dB steps
based on the measured sound pressure in the interior of the car. This means that the volume can be
increased by up to 20 dB with respect to the set volume level. This implies that care should be taken
that the booster and loudspeakers do not become overloaded
