Connecting the subwoofer
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.
CAUTION
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.
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.
Note:
•
All SUB 250 inputs and outputs are low level terminals. Thus, neither a power
amplifier output must be connected to the subwoofer nor loudspeakers can be
driven by the subwoofer directly!
