A PT2353H volume control circuit consists of ladder resistors and analog switches. The Tap for
Loudness Function (LT & RT) is connected to the Step 10 (-20dB). Therefore, the Loudness Function
Effect will be clearly audible when the volume setting is less than -20dB. Please refer to the attenuation
table given below.
