Connections/Rear Panel - NHT B-20 Owner's Manual

CONNECTIONS/REMOTE CONTROL
13
Stereo/Mono Switch:
Remotely selects between the stereo and mono operating modes. The mode you've selected will be confirmed by the B-20 Control
Amplifier's Blue LED, as previously described.
14
Sub Bypass Switch:
Remotely selects either bypass or operational mode for the B-20 Control Amplifier; the green LED will confirm the mode as
described above.

CONNECTIONS/REAR PANEL:

15
Subwoofer Output -- Left and Right:
The output connectors to the two subwoofers are XLR.
Amplifier left and right outputs to the B-20 subwoofers.
16
Satellite Output -- Left and Right:
The TRS output jacks pass the left and right signals to the left and right monitors used with the B-20 system. Their frequency output
is determined by the settings on the front panel SAT HI PASS control and the remote control bypass switch. If the B-20 is used
strictly on an LFE channel, no satellite connection is necessary.
17
Input Section:
The B-20 has two different input options: balanced TRS or XLR. Standard 1/4" connectors maybe used in place of the TRS type
if the source equipment employs unbalanced outputs, but this method will not provide the noise cancellation advantages of fully
balanced operation. Tech Tip: The XLR and TRS input jacks are wired in parallel. You can therefore use the unused input as an output to
another device like a DAT machine or additional monitor system. You can also daisy-chain multiple subwoofer/satellite systems for fixed
installations.
18
Remote Control Input:
This is where the supplied RCU (remote control unit) is connected. A 13' TRS cable is included; one end connects to the remote
control input on the B-20, the other to the B-20 remote control itself.
19
Power Section:
Here you'll find the power cord receptacle, and a spare fuse located within the power connector, as well. To get at the fuse, remove the power
cord and use a small flat-head screwdriver to access the fuse compartment. When replacing the fuse with a spare, use only a fuse of the same
power rating. Located next to the power cord receptacle is a voltage selector, preset at the factory for the destination country; the power cord
supplied is appropriate for that voltage. As noted elsewhere in this manual, confirming the voltage selector setting before powering up the
system is a good idea.
