  • Page 30: The Effect Of Eq

    Setting the Correct Input Gain The Siena’s input channel has a mono microphone and line input. Gain is provided on these channels to allow the operator to obtain the optimal signal for the system.
  • Page 31 Unity gain is a gain of 1 (i.e. no gain or attenuation is applied to a signal). If a signal entered a mono line level input of the Siena at 0dBu and the gain was set to +15dB (an internal 15dB attenuation sets the net gain to 0dB), then the signal was routed to each output at 0dB, the channel fader was set to 0dB and each output fader was set to 0dB, the output should be 0dBu (or unity).

  • Page 32: Signal Processing And Amplifiers

    Graphical equalisers have the same problems as the Siena’s EQ. If excessive boost is applied to the signal, the graphic equaliser’s output may be overloaded. If, the output of the Siena is higher than the maximum input level of the graphic, the input of the graphic may be overloaded.
  • Page 33 Busses and Routing Siena has a master stereo bus plus 16 mix bus outputs which may be used as auxiliary sends or group outputs depending on the application of the console. This generic approach to the mix bus structure enables the console cover a wide range of applications.
  • Page 34 Dual Purpose Front of House (FOH) and Monitor Applications With its flexible routing and feature set, the Siena is happy to run both the front of house (FOH) mix and provide monitor mixes for the artists on stage. In this dual purpose application, you will want to use some of the 16 mix busses, as above, to generate your monitor feeds to the stage, while the remaining busses can be used to generate audio sub groups.
  • Page 35 Setting Up The Siena Setting Up The Siena Busses and Routing Auxiliary Sends Typical Configuration When determining how many mix busses you wish to use for auxiliary sends, you may wish to consider the following. We've also provided some recommendations on how to configure each send, depending on its application.
