Procedure C - AMIX SNA 70 Manuel Utilisateur

2°) Heavy dynamics:
In that case, the average density can be thought as relatively low, because the music mainly consist of low or middle level,
with short high levels. To respect the dynamics, attack time will be long enough to preserve attacks. Release time can be
faster, allowing the regulator to come back to initial state (0dB when the level decreases).
Example :
Attack and release times setting determine the regulator efficiency.
To change these values, use on the keyboard
There are 8 values for attack and release times (in s or ms for 10dB)
Attack and release times act only on global limitation
Table :
1 - Select page 1 using of
2 - Select the parameters to set
3 - Set the attack time using of keys
4 - Validate the value of attack time in pressing on

The configuration is to carry out only on integrated cards in SNA 70. If cards are not on some frequencies, SNA
will display "missing card".
- To be on séquences in filter pink noise by octave bands supplied CD with device.
Séquence 2 = filter pink noise 63 Hz

Séquence 3 = filter pink noise 125 Hz

Séquence 4 = filter pink noise 250 Hz

Séquence 5 = filter pink noise 500 Hz

Séquence 6 = filter pink noise 1KHz

Séquence 7 = filter pink noise 2KHz

Séquence 8 = filter pink noise 4KHz

- Check with your switch sono meter depending on octave band in public level that SNA70 controls indicated levels. To respect
a minimum spectral on audio signal, the maximum level fade has limited to 12dB by ocatave bands.
- Do a last test on a audio message.
- Close the 2 hoods (front and rear for SNA70 Rack, the 2 of front for SNA70 unit).
The device is ready for use.
