3 Wiring and Settings
Hydra has an input made with a female NL4 connector. Through a dedicated cable and terminated
with 2 male NL4Fc connectors it is connected directly to the output of the power amplifier. The
connectors are standard NL4 (+ 1 / -1 con 2 / -2 empty) or water proof on request.
In case of custom realization by the installer of the connection cables, we recommend specifying
installation-grade Low Smoke Zero Halogen (LSZH) cables for permanent installations. The cables
should use Oxygen Free Copper (OFC) of grade C11000 or above.
For distances of over 15 meters between Hydra and amplifiers we recommend increasing the
section of the cable poles to 4 sq mm, to avoid excessive emission level losses. For lengths of less
than 15 m, you can use 2-pole cables, each with a section of 2.5 sq. mm.

Cable between Hydra and amp (not supplied): 2-pole cable (section
2.5 sq mm minimum per pole up to cable length of 15 m, in addition we recommend switching to
4 sq mm for pole), terminated with Nl4Fc male connector (+ 1 / -1 connected and corresponding
to +1 red and -1 black on the amplifier, + 2 / -2 empty) to connect to the Hydra input, which has an
NL4fc female connector, standard or WP on request.
