10. ADJUSTMENT OF LEVELS

10.1 Levels of the ZA modules
To perform an equalisation of all the filters, select Automatic level
adjust in the programmer and press T. The digital channels will be
adjusted 10 dB below the analogue channels.
Note: For multichannel filters, the adjustment will be made for the channel
with most level. It is recommended that there should be only one analogue
channel per multichannel filter. If there are more, it is recommended that the
levels of the analogue channels be similar.
