Connection to your amplifier(s) or multi-channel decoder:
We recommend that you leave your main loudspeakers connected to your sound system as usual
for all connection options that are mentioned in this chapter. The use of an additional frequency
limitation for the loudspeakers has, according to our experience, more disadvantages than
advantages and is therefore not included in the following connection examples.
Four connection options a), b), c) and d) are provided:
a) Connection to the amplifier of your stereo system:
Connect the RHEA II like a regular passive loudspeaker to the loudspeaker terminals of your
amplifier in order to operate it in parallel with your main loudspeakers. With this possibility you need
to connect the loudspeaker terminals of your amplifier to the high-level inputs of the subwoofer
(2.3).
•
Connect the amplifier's left channel positive terminal and the subwoofer's L+ input socket.
•
Connect the amplifier's left channel negative terminal and the subwoofer's L- input socket.
•
Connect the amplifier's right channel positive terminal and the subwoofer's R+ input socket.
•
Connect the amplifier's right channel negative terminal and the subwoofer's R- input socket.
Make sure you have the right polarity. If the polarity of
one
channel is inverted, the reproduction of
low frequencies suffers extreme damping!
The active inputs of the RHEA II only minimally stress the amplifier.
We recommend that you use a low-capacitive cable for connection.
In principle follow the same procedure if you need to connect two RHEA II to the loudspeaker
terminals of your amplifier. Make sure, however, that you connect only the right and respectively only
the left loudspeaker terminal of your amplifier to the correct input sockets of each of the subwoofers.
b) Connection to the preamplifier of your stereo system:
If outputs are still available on your preamplifier, you can connect these outputs to the low level input
jacks of your RHEA II (2.1).
c) Connection to the amplifier of your multi-channel system:
Connect the RHEA II like a regular passive loudspeaker in order to operate it in parallel with your main
loudspeakers. Follow the instructions provided under a) in order to connect the left and right channel
of the amplifier's loudspeaker terminals.
In the case of multi-channel systems with centre loudspeakers, make sure that you switch the multi-
channel decoder to "normal" mode and in the case of multi-channel systems without centre
loudspeakers, switch the multi-channel decoder to "phantom" mode. Both modes ensure that the full
bass range is fed into the channels of the main speakers and that the full bass content is fed to the
RHEA II via the loudspeaker terminals. We recommend that you also consult the operation manual of
your multi-channel decoder.
d) Connection to the subwoofer output of your multi-channel decoder
Connect the RHEA II input to the subwoofer output of your multi-channel decoder using the RCA
input. Proceed as follows:
-
Subwoofer output to LOW LEVEL INPUT “L” (2.1) of the RHEA II
If you can adjust both the level control and crossover frequency of your multi-channel decoder, we
recommend that you set the level to maximum and the crossover frequency to the highest possible
value. If in doubt, please consult the operation manual of your multi-channel decoder.
