3) Sub-bass channels operation mode
The possible values are ‘Stereo’ and ‘MonoSum L+R’. With a system using a stereo two way
configuration and having channels 1 and 3 dedicated for sub-bass operation, it is possible to set
these channels either as independent (i.e. in stereo mode) or with the signals from both Left and
Right inputs summed. Note: this screen is not available on monitor programs or bi-amp with sub
programs.
4) Peak Limiters
Each output has an independent high performance limiter, with both attack and release times fixed
and optimally preset according to the frequency range of the channel it operates on. The values
(displayed in dBu), refer to signal level at the outputs of the unit.
Follow these steps in order to correctly set limiters for your speaker system: Follow these steps in order to correctly set limiters for your speaker system: Follow these steps in order to correctly set limiters for your speaker system: Follow these steps in order to correctly set limiters for your speaker system:
1. Determine the program power handling of the Turbosound loudspeaker (or HF/LF section
as appropriate), or from the engineering data sheet or user manual for that product, or
from the label on the rear of the cabinet.
2. Calculate the required limiter voltage using the formula:
V = V = V = V = √√√√ PR PR PR PR
where V is the limiter voltage setting,
and P is the program power rating of the loudspeaker,
and R is the nominal impedance of the loudspeaker
