How to adjust the volume control and input selector
using a digital source
In the following pages you will find examples of how to connect the TH to a system driven by sources using the
digital input. In order to use the TH IN OPTICAL digital input and therefore its D/A internal converter the DRC
Digital Remote Control MUST be connected to the TH amplifier.
The DRC will perform the function of selecting the source by selecting between Analog Input and Optical Input,
thus allowing the control of Main Volume, Subwoofer Volume, Balance and Fader.
If the last setup working conditions are no more valid, that is if you disconnect the DRC and you had changed
the default conditions, the ASC will automatically go back to use the PRE Analog Input. In this case Fader and
Balance will go back to central position, while general Volume and Sub Volume will go back to 0 dB (maximum
value). The TH display will show the following information:
Warning:
When using the optical digital input you have to use the DRC as main
volume control. If the DRC volume control is at 0 dB it equals to the
amplifier undistorted maximum output power.
To check all the functions and the DRC connection, see pages 56
