9. Option Pre-Out / Filter Function
9.3. Setup with an active subwoofer
The regulated preamplifier output is most commonly used to drive an active subwoofer. The input
impedance of the subwoofer is therefore non-critical.
The Pre-Out does not have a separate muting function to prevent switch-on or switch-off noise from
the V 16 Single Ended. This is normally not needed, however, since the active crossover in the
subwoofer electronics will block unwanted DC and low frequency signals.
During listening with headphones the subwoofer should be switched OFF.
9.4. Bi-amping system
Another option provided by the adjustable Pre-Out is bi-amping via the V 16 Single Ended's Pre-Out.
The V 16 Single Ended would ideally handle the mid/high portion of a bi-amping setup, using a
second power amplifier fitted with its own volume control to take care of the bass. In this
configuration, switch-on/switch-off noises from the Pre-Out may be audible. The best way to deal
with this is to make sure switching on the V 16 Single Ended at first, then the external power amplifier
- and when switching the units off do such in the reverse order.
