INTRODUCTION Thank you for your purchase, and congratulations on your selection of the NHT Pro S-20 powered subwoofer. The S-20 will add dynamic bass response to any pair of smaller, powered monitors, or can be used to reproduce the .1 LFE channel for surround mixing. The S-20 was designed to mate seamlessly with the NHT Pro M-00 and M-20 monitor systems, and offers tremendous flexibility: - Use multiple S-20’s to improve bass output if desired.
6) Input Section: The S-20 offers three stereo input options: two types of balanced inputs (TRS and XLR) and unbalanced RCA. The two balanced inputs are wired in parallel. Note: Standard 1/4” connectors may be used in place of the TRS type if the source equipment employs unbalanced outputs, but this method may induce unwanted noise. PLEASE NOTE: These different connector options have been provided for your convenience.
INITIAL CONTROL SETTINGS: The S-20 subwoofer amplifier has a number of controls which can help you determine optimal placement. A little time spent experimenting with these options should yield just the right solution for your installation. Input Sensitivity Selection: This switch affects the input sensitivity of all three sets (XLR, TRS and RCA) of input jacks. When satellites are connected to the S-20, the subwoofer takes over as the master sensitivity control for the system.
