makes it even more unlikely!)

** The classic way is to use a U47 or similar large diaphragm capacitor 
microphone (like the JOEMEEK JM47); which in itself 'distorts' the sound 
with complex high frequency phasing across the diaphragm and some 2nd 
order distortion from the amplifier tube or FET.

REGULATIONS AND SAFETY

The JOEMEEK SC2.2 Compressor has been designed and built to conform 
to all known safety requirements in the world. Within the European Union 
the Compressor easily meets the requirements for electrostatic and 
electromagnetic emissions, and conforms to all safety requirements of the 
European Common Market. the 'CE' symbol on the rear of the unit indicates 
compliance.
In the United States of America the compressor complies with UL 
requirements and uses UL approved components in all power supply 
functions.

POWER SELECTION

  JOEMEEK Compressors are fitted with a mains voltage selector for easy 
change of input voltage. The fuse carriage can be pulled out and rotated to 
select to the local power voltage.

* In the '115' position, the unit will operate between 95 and 125V AC.
* In the '230' position, the unit will operate between 210 and 240V AC.

The fuse can remain at 100mA for both ranges.

POWER EARTH (GROUND) CONNECTION

The centre (ground) pin of the IEC power connector is connected to the 
metal chassis of the compressor. The Audio ground is also connected to 
chassis.

*  The power system is double insulated throughout so that power ground 
may be lifted off if required without affecting safety in any way.
