Connecting AS2 subwoofer continued
Connection to mono signal with full frequency content
If the subwoofer is only to be connected to a single channel, e.g. when
using two subwoofers in a stereo set-up, and you want to use the sub-
woofer’s built-in crossover network, the 'Mono Input' must be used.
With this set-up, you can take a high-pass signal (without the deep tones)
on the 'Left Output'. Please note that there will be no signal on the 'Right
Output'.
Connection to low pass ltered mono signal
If the subwoofer is to be used with a surround ampli er or other sound
equipment with a ltered mono output to a subwoofer, it is best to con-
nect the signal on the 'LFE Input'. With this set-up, neither the crossover
network nor the volume control in the AS2 has any function; there is also
no access to the signal on 'Left/Right Output'. Any adjustment of the
crossover frequency and volume must be made elsewhere in the system.
Only the phase regulation will still be active and should therefore be
adjusted as described in the section on adjustment.

DALI® recommends that great
care is taken when selecting a
connection method. The correct
connection and adjustment is vital
for perfect results. Similarly, the
choice of signal cables is of great
importance.
