Sep.2014
AF225 was integrated into AF225A along with the AF125.

Dual VCA unit
It is most suitable for cough interface
± 6dB reference variable
Remote cut
High-quality sound
19 inches 1U size

AF225 is dual VCA unit.
Remote control of audio level of high quality is possible with excellent circuit configuration and component.

“Input and output”
It is using general XLR type connecter for input and output of AF225 and it is flexible and promises reliable connection.
Standard input level is +4dBu, but can change it by specification of order regarding input and output reference level.

“Reference”
It is output with 1 to 1 in factory, and the external control voltage can change reference level of (NULL level) on 0V in the range of ± 6dB.

“Control”
CV (the control voltage) is difference input and it is stable and can use even long distances more than 20m.
In addition, it has cut input isolated with photocoupler by every each channel.

“Others”
It can easily build remote audio level control system that AF225 combines it with FU338 of CV fader unit.
In addition, please refer about manufacturing of VCA unit which is different from AF225 in specifications.
