High Pass Delay (STA-1000D)

The High Pass delay Function is a unique capability that allows the sound from the main speakers to be de- layed. This feature allows users who have no means of time aligning their speakers and subwoofer through their AVR or pre/pro (common with two channel analog systems) to add a delay-inducing component to their subwoofer path such as a digital equalizer. The High Pass Delay affects the Output whether or not the High Pass Filter in the STA-1000D is enabled or disabled.

In order for the High Pass Delay to function, the subwoofer must be placed between the output of the preamp/ processor and the input of the power amplifier for the selected channel (front left or right) using either the single-ended (RCA) or Balanced inputs and outputs on the STA-1000D.

From the IFC WELCOME screen, single-click the IFC knob and rotate the IFC knob four clicks clockwise until the display reads “MENU/HIGHPASS DELAY”. Single-click the IFC knob to select the High Pass Delay Function. Rotate the IFC knob clockwise or counter-clockwise to adjust the High Pass Delay value.

The range of adjustment of this control is 0 to 10 milliseconds in 1 millisecond increments.

Room Gain Comp

The Room Gain Comp (Compensation) Function allows the subwoofer to be set to compensate for the increase in low frequency sound based upon the size of the room if it is felt there is too much bass. Small rooms will have a greater increase in low frequency sound than larger rooms. There is no need to use this control unless it is felt there is too much low frequency energy being generated in the listening environment.

This function operates by setting a corner frequency of 40Hz (small size rooms), 31Hz (medium size rooms), 25Hz (large size rooms) or Disabled (no compensation), and allows a target slope of either 6 dB per octave (first order) or 12 dB per octave (second order) roll off from the selected corner frequency. This has the effect of attenuating the lower frequencies below the selected corner frequency at a rate commensurate with the selected slope.

From the IFC WELCOME screen, single-click the IFC knob and rotate the IFC knob five clicks clockwise until the display reads “MENU/ROOM GAIN COMP”. Single-click the IFC knob to get to the Room Gain Comp Function menu. If the Room Gain Comp feature is disabled, a message to that effect will be displayed.

If the Room Gain Comp feature is disabled, turn the IFC knob which will display the Room Gain Comp submenu. To set the Room Gain Comp frequency to a value other than what is currently displayed, single-click the IFC knob and then rotate the knob clockwise or counter-clockwise to set the desired frequency. Frequency choices include 25Hz, 31Hz, and 40Hz.
