Power Connection

Connect the included power cord to the rear Mains Input. Transformer, 
power cord and case connection conform to VDE, UL and CSA require-
ments.  Power  fuse  ratings  are  315 mA  slow  blow  (220-240  volts)  or 
630 mA slow blow (110-120 volts). 

Power Switch

The  rear  panel  POWER  switch  activates  the  unit,  confirmed  by  the 
Power LED on the front panel (between the headphone symbols). 

IMPORTANT ADVICE: Switch on the unit only after you have 
turned all VOLUME controls fully left, and wait to set your 
desired volume level until the unit is powered on. Neglecting 

this can damage either or both your ears and your headphones!

GND LIFT Switch

The rear panel GND LIFT switch eliminates hum by separating the in-
ternal ground from the unit’s housing ground. Hum can, for example, 
result when this unit’s housing has a common ground connection with 
other machines that might have a different ground potential. 

Input Sensitivity IN 2

Inputs IN 1 and IN 2 are gauged to analog line level signals at +4 dBu. 
The second input IN 2 can alternatively be set to another input sensi-
tivity of -10dBV nominal level with the switch next to the IN2 inputs. A 
nominal level of +4 dBu represents the international standard of pro-
fessional  studio  equipment,  -10dBV  corresponds  to  the  standard  in 
consumer electronics, for example a CD/DVD-Player for home use. 

If the switch is actuated, IN 2 is set to +4 dBu, if the switch is not actu-
ated, sensitivity of IN 2 is set to -10 dBV. If you connect a unit adjusted to 
-10dBV to a +4 dBu input, the signal is too quiet (and too loud vice versa). 
In this case change the switch position accordingly.
