Dynacord System Power Amp Xa 4000 - Manual (Page 7)

INPUT
The electronically balanced INPUT offers an input sensitivity
of 0dBu (775mV) for direct connection of mixing consoles,
equalizers, etc.
The XLR-type connector OUTPUT is prepared for “through-
connecting” input signals to additional external power amps.
The input signal is directly routed to the output connector.
There are no repeaters or other electronic components within
that signal path. Accordingly, input and output connectors
are directly interconnected in parallel, offering permanent
electrical connection, without regard to the setting of the
Power-ON switch.
NF-CONNECTION CORDS
Choosing high-quality balanced cables (two conductors for the audio signal plus separate shield-
ing mesh) with XLR-type connectors is recommended for LF-signal connection. Although connecting
unbalanced cables to the power amplifier inputs is possible as well, using balanced cables is always
preferable. A great number of today’s audio appliances employ balanced outputs. With balanced ca-
bling, the shield connects all metal enclosure parts and therefore efficiently eliminates the introduction
of external interference – mostly noise and hum.
