STA-400D Connectivity and Panel Operation
The STA-400D Sledge™ amplifier in this SVS subwoofer has simple and straightforward connectivity and control options that make integrating the subwoofer into the
listening environment an easy task. Even though the STA-400D uses what appears to be analog controls, all functions are actually implemented digitally in the amplifier. This allows a more linear and accurate implementation of controls which again, facilitates setup and repeatability of configuration.
Inputs
There are two low level input connectors on the STA-400D: One labeled Line In Left (white) and the other labeled Line In Right (red). The input signal(s) can have a “High Pass Filter” applied which affects the signal presented to the STA-400D’s “High Pass Out” RCA jack (single output).
Input Configuration
Typically today most Audio Video Receivers (AVRs) and Pre-amp Processors (pre/pros) have subwoofer/bass management capability. So, connectivity to the STA-400D amp is usually via a single coaxial signal cable terminated with familiar large
pin-type RCA connectors. SVS sells such cables in several common lengths. The subwoofer signal cable runs from the “Subwoofer Pre-Out” on the AVR or pre/pro to either the Left or Right low level input of your sub. It does not matter which you use. This “typical” hookup assumes: 1.) The AVR or pre/pro does bass management for the satellite (SAT) speakers connected to it. 2.) Handles the merging of any LFE (.1 channel in multi-channel audio) content with the bass from the SAT speakers. 3.) Manages the proper delay of all speakers and the subwoofer through a distance or time delay function for each utilized audio channel. Nearly all modern AVR’s do each of these things. (see figure 4)
