SONOSAX SX-S - Manual (Page 4)

• The EQ switch allows the filtering of 80 Hz, 8 kHz and MF tones.
177.3.7 Pan Pot (Panoramic Potentiometer)
178. The Pan Pot allows progressive switching of the modulation from left to right.
179.
180.3.8 ON Switch
181. With S-4 on the circuit board in Power position this switch turns the entire power to the module on and off. An audible pop will be introduced on the mixer's output if this
switch is used during operation. This function is useful to conserve power when only a few channels are being used.
182. With S-4 on the circuit board in Mute position all power is applied to the module but its output is muted unless the switch is depressed. Channels can be preset and
switched on to the mix bus during operation with no pop.
183.
184.3.9 Aux level
185. The AUX potentiometer (auxiliary) allows separate mixing of different inputs for mono output or special effects such as an echo room, etc. The PRE/POST push button
allows selection of the modulation before (PRE) or after (POST) the fader.
186.
187.3.10 Limiter
188. Each input module is equipped with a limiter. The audio level above which the limiter is activated (Limiter LED lit) is controlled by the THRESHOLD knob. The limiter may
be automatically activated if the input gain is too high. This will avoid saturation and ensure a supplementary margin of 6 dB over the maximum input level. This is why
the limiter cannot be switched off.
189. NOTE:The limiter has no effect whatsoever provided the Limiter LED does not light up.
190.
191.3.11 Overload LED
192. The OVD LED lights up 4 dB before saturation level. Overload is measured at mic amplifier output and the equalizer output levels.
193.
194.3.12 Pre - Fader Listening
195. The PFL selector allows pre-fader listening of each input after equalization.
196.
197.3.13 Input Connector
198. The SONOSAX SX-S is equipped with NEUTRIK input connectors equivalent to XLR, Canon, Switchcraft, etc. The standard SX-S version is equipped with female
connectors.
199. The input is floating balanced, transformerless, to ensure optimal performance. On request, the SONOSAX SX-S inputs may be equipped with high frequency R.F. filters.
200. NOTE: Bridge PIN 3 to PIN 1 for asymetrical use! DO NOT USE MIC POWER!
201.
202.3.14 Insert Connectors
203. These are 3-pole, 4.4mm Mini-Jacks. The corresponding connector with 2 meters of cable, other end free is: SONOSAX Part Nr 860133. Plugging the jack in INSERT
opens the circuit between the LF cut output and the equalizer, for insertion of a filter special effect, with asymetric send-return. This jack may also be used as a line input.
In this case, use only the return contact of the jack. The line input at this point avoids passing through the input pre-amplifier.
204.
205.
206.3.15 Line out connectors
207. Same Mini-Jacks as INSERT connectors. Independent asymetrical output. One of the contacts gives the modulation before fader (PRE) and the other after the fader
(POST).

215. 4. STANDARD INPUT MODULE
Differences from the newer Power / Mute modules
216.
217.4.1 Power on/off push-button (red knob)
218. Each input module is equipped with an ON/OFF switch (red knob) in order to optimize power consumption, if all inputs are not used.
219. WARNING: Do not switch on an input module during a sound recording as this causes a pop.
220. Optional MUTE push button (gray knob), replaces Power on/off: supplies constant module powering. The gray knob turns modulation on and off silently ( no pops).
