2 USER GUIDE Channels 1 and 2 Mic / Line Inputs USER GUIDE The Mic/Line Input channel is a mono input with a button switch to select either Mic or Mono Line. Channel 1 is used for the presenter’s mic and is the source for talkback. The Talkback source can be set to come from either the Mic or the Line source irrespective of the channel input selection.
USER GUIDE 2 Channel 7 and 8 – Stereo Line / RCA Inputs Channels 7 & 8 have one balanced stereo input and an unbalanced RCA stereo input. Channel 7 also has DROP IN connector which allows for an input from a a 3.5mm jack connector. Channel 9 and 10 - Stereo Line / Digital Inputs Fig 2-10: Channel 9 and 10 - Stereo Line / Digital Inputs External Inputs Two external inputs are available to the S1 through a 9 pin D-Type connector located on the rear panel.
2 USER GUIDE User Guide – Section 2-3 Front Panel Channel Features Input Selection USER GUIDE Selecting the button changes the channel input connection between Input 1 (Mic) and Input 2 (Line). The button is illuminated in red to indicate when input 2 is selected. When the channel is routed, so that the ON button glows green, the input selection cannot be changed. Channels 3 and 4 have three selectable inputs; Mic, XLR Mono Line, ¼” unbalanced stereo line.
USER GUIDE 2 TRIM Control The Trim control is used to tweak the level of the channel on the PGM output. It provides an additional ±12dB of gain to fine tune the input signal level. It is a good idea to set up all your audio channels so that they are all at the same reference level when the fader is fully up, meaning the mix levels are determined solely by the position of the faders. This is where to use the trim pots, for level adjustment which remains constant through the mix.
U S E R G U I DE 2 USER GUIDE An additional option that is configurable using SCi allows the presenter to CUE/PFL the Telco or STCF inputs whilst preventing the talkback source from being routed to the cleanfeed outputs. If Talkback routing on this channel is ‘disabled’, the CUE/PFL & T/B button shall flash green when selected to indicate that talkback is not routed to the cleanfeed bus. Talkback can be routed to the stereo cleanfeed bus by holding the CUE/PFL & T/B button and the button will glow solid.
USER GUIDE 2 Scribble Pad A scribble pad is provided at the bottom for user labelling of the channel function . This is useful to remind a producer or presenter which channels contain which segments of audio. It is advisable to use a non-permanent pen or pencil in case of changes. Fig 2-22: Scribble Pad Fader USER GUIDE The 100mm VCA fader provides a method of dynamic in-show level control and operates between fully attenuated in its lowest position and unity gain when fully open.
2 USER GUIDE User Guide – Section 2-4 Metering and Monitors USER GUIDE Monitor and headphone sockets The S1 provides a monitoring system to monitor all output channels or the external inputs. The is useful for setting up the mixer outputs or to simply listen to the mix in a control room. There are four jack outputs in total; two paralleled presenter outputs, one guest output and one monitor output. The source which is heard on the monitoring system is selectable via push button.
USER GUIDE 2 Monitor and Headphone Controls Level controls Each monitor output has it’s own level control which operates ona range of zero to ten. Zero represents fully attenuated and ten represents +6dB in the guest and presenter headphones or unity in the monitor. Auto CUE/PFL Split CUE / PFL Fig 2-26: Level controls USER GUIDE When the green illuminated AUTO CUE/PFL button is selected, any input channels selected to CUE/ PFL are automatically routed to the appropriate out.
2 USER GUIDE Dim / Mute When a channel with the monitor mute option configured has PFL selected, the control room monitors can be set to either dim or mute. If the fader is then opened, the monitors will mute irrespective of this setting. The red mute LED will still illuminate if the monitors are set to DIM rather than MUTE on PFL.
USER GUIDE 2 Cleanfeed Outputs The Telco cleanfeed is a mono balanced output used to return a mono version of the program bus back to telephone hybrid. All channels except channel 5, input 2 (Telco) are routed to this bus. Digital Outputs The S1 has two digital outputs that work at the same time. The first is AES/EBU which is on a balanced XLR connector. The second is S/PDIF which is found on an unbalanced RCA connector. These both carry the PGM output.
2 USER GUIDE Auxiliary Outputs USER GUIDE The S1 has two auxiliary buses so that alternative outputs from the PGM can be created and used. The mix that is created on these buses is available from a 9 pin d-type connector which is located on the rear panel. For more information on the use of the auxiliary bus, please read section 3 – Making the most of the auxiliary outputs (page 28).
M I X E R A P P L I C AT I O N S 3 3 Mixer Applications The following section will show you how to setup and use the mixer for most standard applications. It is intended as a quick ‘how to’ guide to get you up and running as quickly and efficiently as possible. If you are already comfortable with setting up the mixer, please move on to the next chapter – Advanced Configuration to learn how to further configure your desk and get the most from your equipment.
3 M I X E R A P P L I C AT I O N S Presenter Controlled Studio The following setup with a presenter in a studio controlling all aspects of the transmission is ideal where space or resources are limited. This kind of setup would suit small radio stations including university or hospital radio. The setup diagrams are divided into 3 figures for clarity.

M I X E R A P P L I C AT I O N S 3 Producer Controlled Studio With Seperate Presenter Setting up the mixer in this way allows the presenter to present and hands the production responsibility to someone else. This kind of setup would be ideal in situations where the presenter is unskilled with mixing desks allowing an engineer to control the audio quality, while the presenter concentrates on the audio content. Another case for this method is if the presenter and guests are being filmed.

3 M I X E R A P P L I C AT I O N S Global Talkback MIXER AP P LI C AT I ON S The Global Talkback Mode provides a method of guests talking to each other when all of their faders are down. The Global Talkback Mode, automatically activates the CUE/ PFL button on the respective channels awell as turning on AUTO CUE/PFL on the Guest Headphones allowing the guests to hear and talk to eachother. The presenter can cancel any of the channel CUE/PFL’s at any time.
M I X E R A P P L I C AT I O N S 3 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 find out more about SCi, turn to section 4) to configure the talkback source to channel 1 Line and lock the channel 1 source button to Mic Input. This will prevent a loop back connection.
3 M I X E R A P P L I C AT I O N S Telephone hybrid Use a telephone hybrid to open the show up to interaction with the outside world. A hybrid allows you to receive phone calls and send them to your mixer as audio. Connect the hybrids audio output to the mixers telco channel (channel 5) and connect the channel’s clean feed output to the line input on the hybrid. The mixer has been designed to work with the SONIFEX HY-03.
M I X E R A P P L I C AT I O N S 3 Use of the external inputs The external inputs found on the rear panel are used to send audio to the presenter and guest headphones and to the monitor output. The external inputs can not be routed to the PGM output. Theses should be used to relay information information or audio to the presenter and guests which should be kept isolated from the transmission path.
