STA-400D Equipped Subs

Setup, Calibration & Integration

From an audio signal connection perspective, there are two primary ways you can connect the sub- woofer based upon the capabilities of the AVR, pre/pro, or preamp you are using in your listening environment:

1)Bass Management and time alignment performed in the AVR or pre/pro. In this configuration it is assumed that the subwoofer will be passed a signal intended strictly for the subwoofer – in other words it has no additional higher-frequency information that needs to be ac- counted for.

Normally, you would use a single coaxial RCA cable from your AVR or pre/pro’s “Sub Pre Out” con- nector and attach it to either the Left or Right Low Level Line In connector on the STA-400D ampli- fier. Turn the Low Pass control fully clockwise to disable the STA-400D’s internal low pass filter. If you have multiple subwoofers you can split the signal at the AVR or pre/pro using a “Y” adapter, or you can daisy-chain an additional subwoofer through the Low Level Line Out connector on the STA-400D amplifier.

2)Bass Management performed in subwoofer. In this configuration, it is assumed that due to the lack of bass management in a preamp (typical for 2 channel analog systems) bass management will be handled using the features of the STA-400D amplifier.

If you are using one subwoofer for the bass of both left and Right Channels, connect the Left and Right preamp Outputs for these channels to the corresponding Line In connections of the STA- 400D. Normally the High Pass Outputs of the STA-400D will be connected to the Inputs of the power amplifier for the main Left and Right speakers.

Using the High Pass Outputs will send all frequencies above 80Hz with a -12 dB per octave slope to the power amplifier for your speakers. The Low Pass filter control on the STA-400D should be adjusted to provide the best integration of your speakers with the subwoofer. If you are using two subwoofers (one for each channel), connect as above using one sub for the Left channel and one sub for the right channel.
