In order to protect the unit from an eventual electrical overload it carries a T 0.5 A fuse. Should it ever blow up,
unplug the unit from mains and replace it with an identical one. If the new fuse blows again contact immediately
with our authorized technical service.
ATTENTION: NEVER SHORT-CIRCUIT THE SECURITY PATH NOR USE A HIGHER VALUE FUSE.
CAUTION: Fuse substitutions have to be performed by a qualified technician.

Phono Inputs
Phono Turntables must be fitted with a magnetic cartridge with nominal output level between -60dBV and -20dBV
(1 to 100mV). The PHONO inputs (38) of the EVO4 have a high headroom (margin before saturation) and it can
handle higher output cartridges than what is usual. These inputs are supplied with a nominal input sensitivity of
-40dBV (10mV).
Line Inputs
The sensitivity of the inputs marked as LINE (39) is 0dBV (1V). You can connect sound sources such as CD, DAT
or MP3 players, as well as keyboards and other instruments.
Microphone Input
The MICRO input (40) are prepared for a nominal input level of -40dBV. The connector combine both, JACK and
XLR3, formats. With the TRIM controller it is possible to adjust the input sensitivity between -30 and -50dBV. These
microphone inputs are prepared for balanced signals, which have to be connected as follows:
Hot or direct signal
> Pin 2 Tip
Cold or inverted signal > Pin 3 Ring
Ground > Pin 1 Sleeve
Microphones must have low impedance (200 to 600
and must be mono. For unbalanced connections, it is
necessary to short-circuit pin 3 to ground or the central ring. The EVO4 equips an 18V phantom power supply for
condenser microphones. An internal soldering jumper allows enabling/disabling the phantom
power. The EVO4’s
MICRO channel is delivered from factory with enabled phantom power. See configuration diagram.
