MIXER APPLICATIONS

Create a talkback source

If you require multiple talkback sources, create a custom talkback mix on an aux channel

and set is to PRE. Connect the Aux Output L to the channel 1 LINE input. After connecting

the presenters Mic to channel 1, Use SCi (to nd out more about SCi, turn to section 4) to

congure the talkback source to channel 1 Line and lock the channel 1 source button to Mic

Input. This will prevent a loop back connection.

Use an auxiliary bus to create a clean feed for a hybrid unit

If the user would like to use a second hybrid, an auxiliary channel can be used to create a

clean feed return. Turn the gain to all channels that are being broadcast to the required

levels except for the channel which is receiving the audio from the second hybrid. Select

POST so that everything that is heard has been mixed correctly. This channel should be

muted. Connect the left channel of the auxiliary output to the the second hybrids clean feed

input. If presenter would like to talk to the caller o air, turn o the presenter channel and

fade in. This will allow the the presenter to be heard on the auxiliary bus but not on the PGM

output. The presenter can press CUE PFL on the second hybrid channel to listen to

the caller.

User Guide – Section 3-4 External equipment and the S1

Most of the equipment needed such as microphones, headphones and CD players are self-

explanatory. Occasionally you may need extra external equipment to really make the most

of the mixer. Here are a few suggestions:

Headphone distribution ampliers

If the application requires more than one set of guest headphones, then a headphone

distribution amplier is required. This will take one headphone output and create multiple

new outputs from it, without aecting the signal or line impedance. Simply take the

output from the guest headphones socket and connect it to the distribution amplier. It is

recommended that you use the SONIFEX RB-HD series.

Microphone ampliers

Some applications may require more microphone inputs. If this is the case you could

use the Line inputs with dedicated microphone amplier. Connect your microphone to

the amplier’s input and connect the amplier’s output to the required line input. It is

recommended that you use the SONIFEX RB-MA series.
