Operation
Dynaudio Sub 250 7
Operation Connecting the subwoofer
Note: The Dynaudio Sub 250 can be controlled by any source provided with a LFE
or preamplifier output. In the operating manual the expression “processor/
receiver” will be used for all these sources.
Subwoofer inputs
The Dynaudio Sub 250 provides two different signal inputs:
SUB I/O - LFE/Slave In
This input allows the LFE (Low Frequency Effect) channel to be connected, which is
used in Home Cinema systems to reproduce low frequency effects.
The signal is:
• reproduced by the subwoofer
• routed to the SUB I/O - LFE/To Slave output for a second subwoofer to be
connected.
The SUB Lowpass control has no impact on this input.
SAT/SUB Input
This input allows the connection of the full bandwidth signal from the processor/
receiver (preamplifier out).
The signal is:
• reproduced by the subwoofer,
• routed to the SAT Output terminals. Low frequencies are cut-off according to the
SAT Highpass setting,
• routed to the SUB I/O - LFE/To Slave output for a second subwoofer to be
connected. High frequencies are cut-off according to the SUB Lowpass setting.
See figure left for correlations between input, output and settings.
Note: All Sub 250 inputs and outputs are low level terminals. Thus, neither a power
amplifier output must be connected to the subwoofer nor passive
loudspeakers can be driven by the subwoofer directly!
NOTICE
Damage of device due to improper connection
X Set the mains power switch to OFF before connecting the Sub 250.
X Only switch the subwoofer on (mains power switch to ON) after all connections and
set up steps have been properly completed.
