echo systems
BA7725S / BA7725FS
The BA7725S and BA7725FS are analog companders designed for KARAOKE echo systems, and logarithmically
compress the signal level by 1 / 2 and then logarithmically expand it by a factor of 2. These ICs can be used in com-
bination with the BU9252S or BU9252F to create a digital echo system. These ICs have an internal line mixer ampli-
fier for mixing line input and echo signals. The internal electronic volume control makes it possible to adjust the mixer
level and loop level mixer with an external DC voltage.
Applications
Circuits that require analog signal compression and expansion
Features
1) Internal logarithmic 1 / 2 compression circuit and 2 ×
expansion circuit
2) Internal 2-channel buffer amplifier used as a tertiary
low pass filter
3) Internal mixer amplifier that mixes line input and
microphone input
4) Internal electronic volume control allows for adjust-
ment of the echo mixer level and loop mixer level
using an external DC voltage.
5) Internal microphone amplifier and microphone input
