Passive Stereo 2. 1 : AIW150E / AIW350e pair + ALF40
The ALF40 has been optimised to work with the Amina Evolution series of Invisible speakers.
The following examples illustrate its use with these series of speakers, however the ALF40 can also be
used to enhance other manufacturers speakers. The ALF40 is designed so it can be connected in
parallel with AIW speakers.
Non Amina satellite speakers should be a minimum of 8 Ohms if wired in parallel with an ALF40.
Note: Amplifier must be 4 Ohm stable.
In this scenario, one of the amplifier channels (left or right) is used to drive the ALF40 and one of the
Evolution speakers together in parallel. It is assumed bass frequencies are mixed in mono on most
program material, however for orchestral music better performance will be obtained with the ALF40
connected to the left channel of the amplifier.
The output of an ALF40 in most situations will match a pair of Evolution speakers.
Note:
You may need to adjust the amplifier’s balance control to obtain an equal output from the Evolution
speakers.
