The connection is different if the speakers are used in a multi-channel system or in a 2
channels system :
A.
Connection in a Multi-Channel system
If used in a multi-channel system:
• One Logos 2 may be connected to the Subwoofer channel, either in analog or digital (for
Digital Input set-up see also the Universal Preamplifier User Manual for set-up detail).
• Two Logos 2 Subs may also be connected in parallel to the sub-woofer channel in analog.
• To match the Logos 1 speaker in frequency response, use the position 5 (50Hz position)
of the crossover frequency adjustment and for Logos 1 HE use position 4 (55Hz). Level
adjustment depends on the room acoustics.
• The 2nd & 3rd positions of the crossover are set for higher crossover frequencies
(around 150 at position 2 and 80Hz at 3). Do not use it for linear response but only
to emphasize the low frequency effects.
• The 6th position provides a 35Hz cutoff frequency and is used to complement a
system based on the Goldmund Epilogue 1 speakers.
• The 1st (infinity) position provides the option to exclude the internal filter if using
digital filters.
B.
Connection in a two channel Stereo system
When used in a stereo system, a Logos 2 Active may be used to complement in low
frequencies a pair of Logos 1 or Logos 1 HE speakers, or even a pair of Epilogue 1 speakers.
You may use one or two subwoofers in analog:
• For two subwoofers connect the right channel source output (usually the
preamplifier) to the right subwoofer analog input (labelled 1 ANA on the rear panel).
Fit the shorting plug to Analog Input 2 (labelled ANA 2). Then connect the left
channel source output to the left subwoofer, also using Analog Input 1 (marked
1 ANA) and fit the shorting plug to Analog Input 2 (marked ANA 2). This is important
because the autostart detection system operates on Input 1 only.
The Logos 2 subwoofers should then be aligned to the same distance as the main
speakers from the listening point.
