(11) IR Input

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

(12) 12V Trigger

When this 2-conductor mini-jack is connected, the amplifier remains in power-off mode until the trigger is applied. The correct trigger is +12V on the tip of the connector relative to the grounded sleeve.

(13) RS-232 In

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 amplifier 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 amplifier 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 SC-602 amplifier to your receiver using the line input/LFE input connection (Item 10), connect these input terminals to the speaker output terminals of your amplifier or receiver. If you use this method of connection, make sure to select the “large” speaker option in the receiver’s set-up menu. Also, select the option for no subwoofer. This will make sure all bass and LFE information is fed the speaker outputs and be received by your SC-600D amplifier.

Note: Using both speaker terminals and the line level inputs is not recommended, as this may damage the SC-600D 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.
