Balanced Connections

If your preampliÞ er has XLR outputs, it can be connected to the XLR inputs as shown. This example shows the connec-
tions to the SunÞ re Theater Grand III processor. This also shows the Current Source output connections to the front left
and right speaker inputs. (The Voltage Source outputs can be used instead, as shown on the previous page).

The 12 VDC trigger connection
shown can be used to turn the ampli-
Þ er on when the preampliÞ er turns on.
Alternatively, you could use the ampli-
Þ er's AUTO-ON switch. The ampliÞ er
will then automatically turn on when a
preamp audio signal is received.
