OUT 1
These stereo output connectors feeds to the PA system through balanced XLR3 or unbalanced RCA connectors.
The nominal output level for OUT 1 (45, 46, 47) comes standard at 0 dBV (1 V) but internal solder bridges may be
used to set it to +6 dBV. The output volume of OUT 1 can be regulated using the OUT 1 potentiometer (31).
The L+R switch (25) adds up the left and right signals from the OUT 1 and OUT 2 outputs. This function is
especially useful if there is a malfunction in one of the channels during a session (e.g. turntable needle does not
contact properly). When this switch is activated, the mixer sends the sum of L+R signals to both speakers, which
prevents most of the audience from noticing the malfunction.
OUT 1 and OUT 2 are equipped with a balance controller, BAL (26).
OUT 2
This output is usually used for independent output from the DJ booth. This stereo output, OUT 2 (48), is equipped
with unbalanced RCA connectors, and its nominal output level comes standard at 0 dBV (1 V), though internal
solder bridges may be used to set it to +6 dBV. The output level of OUT 2 can be regulated using the OUT 2
potentiometer (30).
Recording output
There is a REC output (44), which uses RCA connectors, on the back panel. The nominal output level for REC is
0 dBV (1 V).
FX Send/Return effects loop
The RCA connectors on the FX SEND output (42) and the FX RETURN input (43) allow creating a signal loop for
external effects processors, samplers or sequencers. The nominal level for the SEND output, as well as for the
RETURN input, is 0dBV (1V).
Headphones
In order to obtain an optimal performance during their operation, the headphones should have high impedance
(200-600
Headphones are connected to the headphones output (36) located on the controllers plate. A
normalized ¼’’ stereo jack or 3,5mm mini-jack is provided for this connection. The sleeve is ground, the ring is the
right channel and the tip the left channel.
3.3. Digital connections
MIDI OUT
MIDI (Musical Instruments Digital Interface) is a standard communications protocol used for electronic musical
instrument-to-computer connections. MIDI devices may act as a master (controller) or slave (controlled) devices.
The EVO4 works as a master unit, meaning that it can control other electronic musical instruments (synthesizers,
sequencers, rhythm boxes, software and even light controllers). With the EVO4, MIDI CLOCK signals may also be
sent if this option has been enabled. A standard DIN 5 (180º) connector pin is used to establish a MIDI OUT
connection.
USB port
The EVO4 includes a USB-MIDI interface that allows you to send MIDI signals from the mixer to a computer via
USB.
You can also use the USB port to up
date the equipment’s firmware.
