j ai trouve ca, serait ce une bonne solution ?
on peut y brancher 4 amplis, et surtout un switch ground/lift, est ce que ca peut marcher ?
pour les anglophones, tirer du site.
Each amplifier output is coupled using a high quality shielded and sealed transformer.
Isolating each output with a transformer is what breaks the ground paths between
amplifiers. Without this, current would flow through ground loops causing your amps
to hum. In addition, we have developed a proprietary matching technique to drive the
transformers. By carefully matching impedances and component values we are able to
greatly improve the performance of the transformer. The result is a true, super accurate
sound without any loss of tight low-end response.
Ground Problems
You should always start with all of the Amp Selector’s Grounds Lift switches in the ON
position. This means the output is grounded. If the amp is humming, the first place to
look is if there is a two or three position ground switch on the amplifier itself. Try each
position of the amp’s ground switch to find the least hum. If the amp continues to hum,
then try switching the Amp Selector Ground Lift to the OFF position. This now isolates
that output. Then try each position on the amp’s ground switch again to find the least hum.
If you are still having problems, make sure that all amplifiers are powered from the same
power source. Outlets in different parts of a room can have significantly different ground
potentials making it more difficult to find settings that are hum free.
Since ground connections in a multi-amp setup can get complicated, you may need to
experiment a bit with different combinations of settings to find one which keeps all the
amps from humming.
