b) Horizontal bi-amp mode
In horizontal BI-AMP mode, one 218 power amplifier feeds the mid-high
frequency paths of your loudspeakers and another feeds the low frequency
paths. In this mode, the power amplifier, which is responsible for the
mid-high range, is completely unburdened by the low frequencies.
1. Connecting a preamplifier for horizontal bi-amp mode
Place your device in a suitable location.
Make sure that all connections are easily accessible.
Switch off both 218 units and all other components before connecting.
Connect the left and right outputs of your preamplifier with one Burmester bi-amp

Use Burmester XLR cables to extend the connection of the bi-amp adapters to your
preamplifier or to the amplifier inputs. Longer, custom-made Burmester adapter
cables are also available on request.
If your preamplifier does not have the appropriate outputs, you can use the enclosed
adapters. Please ask your dealer about this if necessary.
2. Connecting the loudspeakers for horizontal bi-amp mode
Connect your loudspeakers as shown in figure 4.
When connecting, also observe the operation manual for your loudspeakers.
CORRECT POLARITY
When connecting the loudspeakers, make sure that the connections have the
correct polarity. It is important that you make all connections in phase: positive output
on power amplifier (+) = positive input on loudspeaker (+) negative output on
power amplifier (-) = negative input on loudspeaker (-).
Do not switch your hi-fi system on again until you are sure that all the devices
are connected correctly. Set your preamplifier to a low volume first.
