AC TRIG [AC Trigger] Pinhole Switch
BBE® Sound Enhancement
The AC TRIG pinhole switch (see Figure 21) lets the ASAP3D SE determine the precise voltage appearing at its AC TRIGGER OUTLET that will trigger the amplifier to switch from the House to the Local source:
1.Place the TV that is connected to the AC TRIGGER OUTLET in the Standby or OFF mode.
2.Push the AC TRIG button.

The Sonamp ASAP3D SE incorporates BBE® Sound Enhancement. The BBE process improves music’s presence and detail, especially at lower listening vol- umes. This improves the sound of your audio system, particularly distributed audio systems playing background music. BBE also restores clarity and definition (or focus) to spoken voices, which makes paging systems easier to understand without having to run them

SWITCHES
•The HOUSE AND BBE LEDs on the ASAP3D SE’s front panel will flash and the amplifier’s microprocessor records the (minimum) voltage level at the AC TRIGGER OUTLET.
3.Turn the TV’s power ON.
4.Push the AC TRIG button again.
•The ASAP3D SE’s microprocessor records the (maximum) voltage level at the AC Trigger Outlet,
5.The ASAP3D SE calculates an AC trigger voltage that is between the maximum and the minimum voltage levels that will appear at the AC TRIGGER OUTLET. (This allows the amplifier to switch sources when the TV turns ON.)
•When this process is completed the HOUSE AND BBE LEDs will stop flashing.

To reset the AC Trigger Voltage to its factory level, unplug the amplifier’s AC cord and plug it back in while
at high volumes.
The ASAP3D SE has 2 individual switches to set the BBE enhancement (see Figure 23):
•If the BBE ON/OFF switch is set to OFF, BBE enhancement is not applied.
•If the BBE ON/OFF switch is set to ON, BBE enhancement
is applied according to the setting of the LO/HI switch: LO = +3dB of BBE enhancement; HI = +6dB of BBE enhancement.
