  • Page 5: Introduction

    25 years of experience have helped us to develop and build this mixer which is designed to last a minimum of 12 to 15 years. The reliability of the SONOSAX SX-ST or SX-VT is due to a high-tech design, the choice of the best components available, a meticulous hand assembly and a severe quality control.

  • Page 6: General Description

    SX-ST10, for up to 10 input modules, or up to 9 inputs and one Digital or Recorder module The SX-ST series being fully modular you can purchase with a few number of modules and add more modules or options at a later date.

  • Page 7: Installation

    Do not use the SX-ST / SX-VT console and its power supply near water, avoid moisture. • Keep the SX-ST / SX-VT console and its power supply away from heat sources such as radiators or other devices that produce heat.

  • Page 8: Battery Power Mode (Sx-St Series Only)

    SX-ST without using any other tool. WARNING: Never leave discharged batteries in your SX-ST. Make sure that your SX-ST only contains rechargeable NiCd or NiMH batteries before charging. When using dry cells, use only professional alkaline batteries to ensure optimal autonomy.

  • Page 9: Closing The Battery Compartment

    2.5A. The average power consumption is approximately 2A. The SX-ST series is supplied with an auto-ranging power supply 100 to 240 VAC 50 or 60 Hertz, that can be used worldwide without modification or setting changes.

  • Page 10: Ac Power Mode (Sx-Vt Series Only)

    The internal DC/DC converter circuitry is designed to automatically changeover between the internal batteries and the external DC power supply. You do not need to power OFF the SX-ST to change the power source. While powering up the mixer, when both the external DC power supply is connected and the internal batteries are installed, the internal DC/DC converter will first connect to the external DC power supply even if the external DC voltage is lower than the battery pack voltage.

  • Page 11: Mic / Line Input Module

    For ages this type of circuit has been used for analogue recording and nowadays The new SONOSAX SX-ST & SX-VT input stages do not reduce the microphone level before amplification. Instead we control the amount of amplification and therefore no additional noise is introduced by this method.

  • Page 12: Input Select Switch

    Caution must be taken when equipments other than a condenser microphone is connected to the 25pin Sub-D. : The SX-ST / SX-VT mixers do not provide with T12 and P12 voltage supply. Some 48V phantom to NOTE T12 or P12 adapters are available on the market 4.3 ∅...

  • Page 13: Lf Cut And Equalizer

    4.5 LF Cut and Equalizer The SONOSAX SX-ST / SX-VT series input module is equipped with a powerful filtering and equalization section. Its design is derived from our previous model SONOSAX SX-S on which the efficiency and sonic integrity have been well proven in practice for decades.

    4.7 AUX Sends 1 to 4 The SX-ST / SX-VT mixers provide with 4 Auxiliary Sends mix busses. AUX 1 to 4 are used to create mixes for headphone cueing, effect sends, stage monitor mixes and all kinds of different sub-mixes.

  • Page 15: Limiter ( Non Vca Version Only )

    The input stage in the SX-ST / SX-VT is having such a significant headroom that it is normally not necessary to reduce the input gain. However, when the ambiance sounds become more silent, it may be necessary to increase the level so much that the traditional +12dB fader gain is not enough.

    This Led will light ON only when the compressor becomes active and turns OFF when the compressor is inactive, depending if the signal level is equal to or higher than the threshold point. SX-ST / SX-SV User Manual (SX-ST series only)
