2. GENERAL DESCRIPTION The SONOSAX SX42 is an ENG/EFP mixer of the last generation, designed in 2002, using the latest available technologies, with the unequaled SONOSAX design and ergonomics. Our 25 years of experience have helped us to develop and build this mixer which is designed to obtain a minimum of 10 years life-span, despite an intensive use under the worst possible conditions.
A universal batteries charger for NiCd or NiMH accumulators is available as SONOSAX part number: SX 008415. 2.2.7 Nylon case A black nylon bag is available for an easy and protected transportation of your SX42 mixer. Its SONOSAX part number is: SX 005110. SX42 User's Manual...
• Follow all warnings, notes and instructions in this operation manual. • Keep the SX42 mixer and its external power supply away from heat sources such as radiators or other devices that produce heat. • Connect the SX42 mixer only to the optional external power supply delivered by SONOSAX.
3.2.3 Batteries charger (optional) An external NiCd or NiMH batteries charger is available as an option for the SX42. It can charge simultaneously up to four 1.5V D-cells (LR20) or up to six AA (LR6) accumulators.
ON position to turn on the unit. The LED between the two level meters must come green, if not: Check that the DC output voltage selector located on the external power supply is on the 12V position. SX42 User's Manual Page 9 of 26...
SX 860273. 4.1.3 External DC input (DC IN) You can provide power to your SX42 mixer from an external power supply. The voltage must be stabilized in a range between 6V to 12V DC. The average current consumption is around...
500mA, but due to the internal DC/DC converter of the SX42 mixer, the peak current when the unit is turned ON reaches 1A. For the best performance we recommend to use the optional external power supply provided by your nearest SONOSAX dealer or by the factory. Its SONOSAX part number is: SX 008420.
SONOSAX dealer or at the factory. Positions 1 to 5 have 6dB/step. See the PHONES switch on the Front Panel and Headphones level adjustment in the INTERNALS SETTINGS section. NOTE: The headphone amplifier of the SX42 mixer is very loud, and in some cases this can damage you hears! 4.2.4 Direct outputs (OUT 1to4) This is a four channels unbalanced output, corresponding to the four input channels of the SX42 mixer.
This switch allows to turn ON or OFF the 30dB input attenuator of the corresponding input channel (IN1 to IN4): MIC position: the input attenuator is OFF. PAD position: the input attenuator is ON. SX42 User's Manual Page 13 of 26...
This switch allows you to link level controls (rotary faders) of input channels 1 and 2 (and respectively input channels 3 and 4) to the single level control of input channel 2 (respectively SX42 User's Manual Page 14 of 26...
LINK position: Left and Right output limiters are linked (stereo mode) and ON. OFF position: Left and Right output limiters are turned OFF. ON position: Left and Right output limiters are turned ON. SX42 User's Manual Page 15 of 26...
Feel free to connect it according to your needs. 4.4 Front Panel The front side of the SX42 includes all the figures used during the shooting, and all the monitoring functions. 4.4.1 Input rotary faders (IN1 to IN4) These four rotary potentiometers (faders) allow you to progressively adjust the desired audio level of the corresponding input channel (IN1 to IN4), within a wide level range going from -∞...
NOTE: The nominal headphones output level is fixed at 0dBu and it can be internally adjusted by your nearest SONOSAX dealer or at the factory. 4.4.5 Meters source (MON OUT) This switch allows you to select which audio signal will drive the two level meter indicators according to the following: MON position: level meters will follow the monitor source signal.
The two level meter indicators have a red backlight with an automatic power ON or OFF function. As soon as the detected daylight goes under a certain level, the meters backlight will light ON. Thus, when using the SX42 mixer in a normal daylight environment the backlight is turned OFF.
(minimum: 1V, maximum: 1.6V). In case of use with an external power supply, the meter will indicate the voltage divided by four. For instance: a 1.5V indication means that the external voltage is equal to 6V DC. 4.5 Bottom Panel SX42 User's Manual Page 19 of 26...
Please pay attention that these internal adjustments must be executed by a qualified technician or by a SONOSAX appointed distributor or dealer. Any damage due to manipulations inside the unit cancels the SONOSAX warranty immediately. See the appropriate schematic for proper jumper or trimmer location.
Eight jumpers (S33 to S40) are located on the top middle of the Front Board (see 5.4) and allow you to select the VU or Peak mode of both level meters. Please refer to the table located on the bottom left of the Front Board (see 5.4) for the appropriate settings. SX42 User's Manual Page 21 of 26...
