(11) IR Input

An IR repeater can be connected to this mini-jack.

(12) 12V Trigger

When this mini-jack is connected, the unit remains in power-off mode until 12 volts is supplied. Polarity is irrelevant.

(13) RS-232

Use this port to communicate with an RS-232 controlled touch panel system. See Appendix A for an explanation of the use of the serial port, available commands, and their formats.

(14) Signal Sensing Auto On/Off Switch

With this switch in the “standby” position, your subwoofer can be safely left with the main power switched on continuously. The subwoofer amp will turn itself on automatically when an audio signal is present. If no signal is present for approximately 10 minutes, the unit will switch to standby mode. While in standby mode, your subwoofer amp will draw very minimal power. This function can be disabled by leaving the switch in the “always on” position.

(15) Speaker Level Input Terminals

If you do not connect the IA-400D amplifier to your receiver using the line input/LFE input connection (Item 10, above), connect these input terminals to the speaker output terminals of your amplifier or receiver. If you use this method of connection, when you go to the receiver speaker set up menu, make sure you select the “large” speaker option. Also, select the option for no subwoofer.

This will make sure all bass and LFE information is fed to the speaker outputs and will be received by your IA-400D amplifier.

NOTE: Using both speaker terminals and the line level inputs is not recommended, as this may damage the IA-400D amplifier or your receiver.

(16) Speaker Level Output Terminals

These connections send a crossed-over speaker-level signal to the front speakers. When connected in this fashion, your satellite speakers will be crossed over at 80 Hz. This removes the lower bass frequencies from your satellites, enabling them to do a better job reproducing high frequencies.

You may also connect your satellites directly to your receiver or amplifier along with the subwoofer if you wish to bypass this crossover.

An example of a speaker-level connection is shown in Figure 3.

FAQ

How do I connect an IR repeater?

An IR repeater can be connected to the mini-jack labeled 11 IR Input on the speaker.

What is the purpose of the 12V trigger?

When the mini-jack labeled 12V Trigger is connected, the unit will remain in power-off mode until 12 volts is supplied, with polarity being irrelevant.

How do I connect speaker level input terminals?

If not using the line input/LFE input connection, connect the input terminals to the speaker output terminals of your amplifier or receiver, ensuring that the large speaker option is selected in the receiver speaker set up menu and no subwoofer option is chosen.
