2.2 Battery Power Mode (SX-ST Series only) 2.2.1 Removing the battery compartment Remove the battery pack by releasing the two slide-locks, tilting the compartment diagonally towards you and lifting it out. IMPORTANT: Keep the slide-locks pressed towards the centre till the battery compartment is completely lifted out of the mixer. 2.2.2 Opening the battery compartment The battery compartment may now be opened by un-tightening the screw on the left side. Remove the plastic

2.2.3 Closing the battery compartment Replace the plastic side cover and tighten the screw. ( Do not over tighten ) NOTE: Certain D-Cells are longer than standard D-Cell batteries and slight difficulty may be found in closing the compartment if such batteries are used. Your nearest SONOSAX agent or the manufacturer in Switzerland can provide assistance if a problem arise due to this difference in length. Replace the battery compartment while holding in the slide-locks and make sure th

2.4 AC Power Mode (SX-VT Series only) The connection of mains the power supply is made by using a mains cable and a standard IEC receptacle. It meets all of the international safety certification requirements. Please make sure that the unit has a proper ground connection. For your own safety, it is advisable not to remove the ground connection at the power supply or fail to make this connection at all. 2.4.1 Operating voltage switch The external Main Power Supply is designed for an AC volt

4. MIC / LINE INPUT MODULE Traditional professional mixing consoles are generally based on the same input structure. The signal from the microphone goes through a phase reversal switch and then to a pad to attenuate the signal before going to the first amplification stage. Some mixers even introduce a transformer before the first stage to simplify the circuits. Reducing the signal level before amplifying it increases noise. It also limits the range of input signal that can be accommod

4.1 Input Select Switch The SX-ST / SX-VT provides with two different connections type per input: one is on a conventional XLR-3F receptacle and the “B” input on a multi-lines 25pin Sub-D connector. This is useful when different sources are frequently swapped ( e.g. a set of microphones and a multi-track recorder/player ) or when a set of microphones are connected using a stage box and a multi-ways cable Position XLR: the XLR input is selected Position IN B: the 25pin Sub-D connector is

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. The Equalizer IN or OUT switch activates or bypasses the filtering of 80 Hz, 8 kHz and MF tones. It is also used for instant comparison of filtered and non-filtered audio. NOTE: The EQ IN/OUT switch can be

4.6 Mix busses 1 to 8 assignment The SX-ST / SX-VT series are equipped with eight groups ( or tracks) mix busses. Channels can be assigned to mix busses Pre or Post PAN Pot using the advanced routing selector switches to create either 8 individual mono groups or up to 4 stereo groups or free combinations of mono and stereo groups. Logically, an individual group is Mono and therefore should not be affected by the PAN Pot. Alternatively, the PAN Pot is needed to build a stereo group. This a

4.9 Limiter ( non VCA version only ) Each input module is equipped with a Limiter switch able ON or OFF. The THRES knob (threshold) sets the level above which the limiter becomes active. The threshold level can be adjusted between infinite and - 30dB. The attack time is very fast ( half sine wave only ) and the release time is program dependant. NOTE: The limiter will be automatically activated when the level applied at the input exceeds 25dBu, even if the Limiter is switched Off. This w

4.12 Channel Power switch (SX-ST series only) It powers ON or OFF the entire input module. This function is useful to save the battery power when only a few numbers of channels are being used. An audible pop will be introduced in the mixer's outputs if this switch is used during normal operation. 4.13 PFL/AFL push button The P/A push button is used to monitor the channel signal Pre-Fader PFL or After-Fader AFL and to check its level on the main level meters. A mode selector located on th

4.16 On Air signaling ( SX-VT serie only ) ON AIR signaling is available on each input channel and can be enabled with Dip switch S5-B. The On Air signalisation is turned On or Off by moving the Fader up and down, providing that the channel is turned ON. The ON AIR Led on the Master module will light On and Off accordingly, and a ON AIR logic command is available on the "Remote and Signaling" 25pin Sub-D connector. When ON, a +3,3VDC voltage is available on this connector. Please take n

5. Stereo Line Input Module The Stereo Input Module is available for the SONOSAX SX-VT series only. It accepts stereo line signals from –14dBu to +25dBu. The Stereo Line Input module is VCA controlled and can be automated from an external device or controlled from an optional built in Master VCA Group Fader if the mixer is equipped with a VCA Grouping system. In following sections, the "Post Fader" signal is obviously always Post VCA and the "Pre Fader" is always Pre VCA. Please keep

5.1 Left & Right Gain Control These gain controls are used to individually trim the appropriate input level of the Left and the Right Channel in a wide range of – 20dB to + 20dB from its centre CAL Position In its centre "CAL" position the line level remain unaffected ( Gain 0dB ) and thus reflect the nominal input level. 5.2 MONO selector If both of the "Mono" selector are switched toward their left position, the Left channel is routed to the Left or the Odd channel of a mix bus and the R

- if PRE fader is selected, the level can still be monitored even if the channel is turned Off ( Muted ) 5.6 Channel Fader The Stereo Input module is equipped with two VCA circuitries ( Voltage Controlled Amplifier ), one for each of the L & R signal. The channel fader controls the L & R audio levels in a range from – infinite to +12dB by means of a single DC voltage equally applied to both VCA's. 5.7 Balance Left – Right The Balance knob also take part of the VCA circuitry. It balances th
