ting will prevent low bass frequencies from
reaching the Monitors. The removal of the low
bass will make integration of the Monitors with
your Evolution subwoofer easier and has the
additional benefit of increasing the Monitor’s
dynamic range and power handling capability.
Method 2
This is the connection method to use if your AV
Receiver has a pre-amp out/main in section.
This connection method is preferred over
Method 1.
- Remove the jumper connections
between the pre-amp L/R front outputs and the
main L/R inputs.
- Connect the Left and Right pre-amp out-
puts from your AV Receiver to the Left and Right
inputs on the X1.
- Connect the Left and Right Hi Pass out-
puts from the X1 to the Left and Right main
inputs on your AV Receiver.
- Connect a single cable from the
Subwoofer/LFE output on the AV Receiver to
the LFE input on the X1.
- Finally, using another single cable, con-
nect one of the Sub outputs on the X1 to the
input on the A-1. Set the mode switch on the X1
to Mono.
Note: If you are using two A1 amplifiers for
stereo bass, as with the T6 tower system, set
the mode switch on the X1 to Stereo and use the
remaining Sub output on the X1 and connect to
the input on the second A1 . Make sure the left
and right channels are wired correctly.
Method 2 - Recommended Surround Settings
Set your Left and Right front speakers to “large”
in your AV receiver. Set all other speakers that
are not capable of producing low bass frequen-
cies to “small”. The “large” setting will send a full
range signal to the X1. The Hi Pass and Lo
Pass controls on the X1 crossover will then be
used to set the crossover frequencies for the
front L and R monitors and the subwoofer (see
section 7). The Subwoofer(s) receive bass
information from the front Left and Right chan-
nels and the Subwoofer/LFE output (see section
8.3).
