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 advanced bus assignment selector allows complex routing configurations. For example, channels can be
individually assigned or mixed Pre Pan to a mono group for multi-track recording and simultaneously mixed
Post Pan onto a stereo group for e.g. pre-mix purposes
The 3 positions switches of the routing selector 1 to 8 are used to individually assign channels to the mix
busses 1 to 8 either Pre or Post PAN Pot as follow:
Switches 1 to 8 in Centre Position : OFF , no audio is assigned to the corresponding mix bus
Switches 1-3-5-7 in Left position : assign the channel to Odd busses Post PAN
Switches 1-3-5-7 in Right position : assign the channel to Odd busses Pre PAN
Switches 2-4-6-8 in Right position : assign the channel to Even busses Post PAN
Switches 2-4-6-8 in Left position : assign the channel to Even busses Pre PAN
The two lines drawn either sides of the selector give a clear view of the Pre/Post PAN assignment: when the
switches are set toward the drawn line, corresponding busses are assigned Post Pan.
A good tip is to remember that, conventionally, Odd busses are defined as Left channels and Even buses are
defined as Right channel in a stereo group. Therefore, by setting Odd switches to the Left and Even switches to
the Right you logically assign the busses Post Pan.
On the Master module, the eight tracks are grouped per pairs: 1/2 – 3/4 - 5/6 – 7/8 thus allowing to control the
output levels of a stereo group by mean of a single Master Fader.
4.6.1 Pan Pot (Panoramic Potentiometer)
The PAN Pot. knob progressively balances the modulation from left to right when used in conjunction with the
Mix Busses Selector switches located above.
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.
When turned fully clockwise, an additional 10dB gain is added to the Aux send bus.
4.7.1 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.
4.8 Dual Peak Level Meters
A dual 5 Leds Peak Meter provided on each input module, shows the Pre and Post Fader levels:
• Red : +6dB lights on xx dB before overload
• 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 tun on
NOTE: the PRE fader level can still be monitored even if the channel is turned Off ( Muted )
