1. Input and Link Connectors
Each channel has one balanced female XLR connector, which accepts an XLR plug
from almost any type of equipment with a balanced or unbalanced output.
Male LINK connectors are connected in parallel with the respective INPUTs, so the
LINK is wired at the same way.
Note: When possible, always use balanced cables. Unbalanced ca-
bles can also be used, but there may be noise problems. In any case,
avoid using balanced cables for some channels and unbalanced for
others.
2. Output Connectors
Each channel has one Speakon® output for connecting to loudspeakers. CH1 and
CH3 provide “4-wire” access to both channels using the standard convention:
y
CH1 uses 1+, 1-; and CH2 uses 2+, 2-.
y
CH3 uses 1+, 1-. and CH4 uses 2+, 2-
y
CH2 and CH4 provide “2 wire” access respectively to CH2 and CH4 only, using
1+, 1-.
3. AC Power Cable And AC Voltage
ZEUS X series amplifiers are designed to operate at 220V - 50/60Hz. Check that
the socket to which the amplifier is connected provides this voltage before turn -
ing on the unit.
Note: If you happen to damage the AC line-cord, always use a three-
pin plug with a ground pin. The wire correspondence is as follow:
Cable Pin International
Brown Live L
Blue Neutral N
Yellow/Green Earth
Always connect the earth! Pay attention to your safety!
Before taking into operation for the first time, the installation has to be approved
by an expert.
4. Ventilation Grids
These grids allow constant ventilation between the front and back of the amplifier.
