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 Right channel is routed to the Right or Even channel of a mix bus.

If the selector of the Left input channel is switched toward its right position, the Left input signal is routed to both the Left and Right mix busses.

If the selector of the Right input channel is switched toward its right position, the Right input signal is routed to both the Left and Right mix busses.

When both selectors are switched toward their right position, then the Left and the Right input signals are mixed into a Mono signal and routed to both the Left and Right mix busses.

5.3 Stereo Equalizer

The Equalizer IN or OUT switch activates or bypasses the Equalizer. It is also used for instant comparison of filtered and non-filtered audio.

The HF controls a fixed shelving equalizer for treble adjustment. Shelving equalizers work on a very broad range of frequencies and, consequently, are very "musical". In an 8 kHz shelf like this section, the upper harmonics of a sound are raised evenly, keeping their original musical relationship to each other

8 kHz / 4dB per octave / ±12 dB at 8 kHz / ±15 dB at 16 kHz

The LF controls a fixed shelving equalizer for bass adjustment. A low frequency shelving equalizer will add or remove bass in a smooth, musical fashion

80 Hz / 4dB per octave / ±12 dB at 80Hz / ±15 dB at 40Hz

5.4 AUX Sends 1 to 4

The 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.

When turned fully clockwise, an additional 10dB gain is added to the Aux send bus.

5.4.1 AUX 1 to 4 PRE/OFF/POST switches

A 3 positions switch Pre/Off/Post assigns the modulation to the Aux busses before (PRE) or after (POST) the channel fader. In its centre OFF position, no signal is sent to the corresponding AUX bus.

In this Stereo Module the AUX sends are paired, therefore the Left channel is sent to the odd AUX 1 & 3 while the Right channel is sent to even AUX 2 & 4.

NOTES: AUX sends signal is taken after the MONO selector and therefore the Left and / or Right channel can already have been routed to either of L or R channels or being MONO mixed.

-If AUX sends are selected Post Fader, the pair 1/2 and 3/4 are also affected by the Balance potentiometer

5.5Dual Peak Level Meters

A dual 5 Leds Peak Meter provided on each stereo input module, shows the levels of the Left and Right channel:

Red : +6dB

Orange : 0dB nominal level

Green : -10dB

Green : - 20dB

Green : - 40dB

When an overload occurs while the meters are set as Bargraph, all Leds turn Off except the upper Red Led When an overload occur while the meters are set to Dot mode, all led's turn on

NOTES:- soldering jumpers S13 & S14 selects whether the Peak Meters are assigned Pre or Post Fader
