NHT B-20 Owner's Manual page 6

CONNECTING THE B-20 ACTIVE MODULAR SUBWOOFER SYSTEM:
THE B-20 IS TYPICALLY USED IN ONE OF TWO WAYS:
!
As a stand alone subwoofer for a surround system; i.e., as a .1 or LFE (low frequency effects) channel (FIG. 6);
!
To augment the range of an active or amplified monitor system (FIG. 7).
WARNING: The B-20 was designed to be connected only to powered monitors, or through the amplifier of externally amplified
passive monitors. Do not attempt to directly connect passive monitors or subwoofers to the B-20 Control Amplifier.
WARNING: As a precaution, check the setting for appropriate voltage prior to plugging the B-20 Control Amplifier into
an
AC outlet.
AS A STAND ALONE SUBWOOFER:
Connect either an XLR or TRS from your designated LFE channel or buss output assignment to either the left
on the B-20 INPUT section. If more subwoofer sensitivity is required, set the RCU to mono mode. Be sure to utilize
surround test tone signals if available to properly balance the woofer level with the other monitor channels. Please read
through the Subwoofer Placement and User Controls sections before you begin.
