Audio amplifier: Notes

The sound reproduction is optimized by the 2 types of amplifier:

• Stereo/Hi-Fi amplifier and
• Top Hi-Fi amplifier.

They are fitted according to the desired type and number of speakers:

The active frequency gates transmit to the amplifier module concerned only that frequency range that can be effectively reproduced by the connected speaker system. The speakers (high, mid and low-range speakers/woofers) are connected to those audio output stages.
