3.2 Ac mains supply cable
Use the cable supplied with the system. If another cable is needed, always
use a cable with specifications suitable to the value of the current involved,
considering the current drain of the system.
CAUTION
The AC socket that powers connector [1], the mating plug and the cable
must be suitable for the current value indicated on panel.
When in doubt, always recruit the assistance of a qualified technician.
We suggest the use of a 3-conductor cable, with a 3 x 1.0 mm
2
minimum
copper section (gauge), suitable for the intended application and
environment and complying with all the relevant safety regulations.
The cable and the plug must be marked with the applicable, country
specific safety approvals, and the plug must be certified for the actual
current value.
3.3 System wiring
AC mains connection
∙Make sure that the AC line voltage value corresponds to the one
indicated on rear panel.
∙Connect the mains supply cable to a socket fitted with a proven
ground contact.
3.3.1 Wiring of signal cables
The input sockets IN (4L) and (4R) and the LINK sockets (5L) and (5R)
are XLR 3 pole connectors, female (IN) and male (LINK). They are wired
according to IEC 268 (AES1492) standards:
pin 1 = ground
pin 2 = hot +
pin 3 = cold –
Use only screened cables (signal cables) of suitable size and quality.
Connector wiring is illustrated in the following images.
