It is red when the unit is off and in manual operation, amber in the standby mode, and flashing green during warm-up. If the indicator flashes and alternates between red and amber, the 2. 1 is in the protect mode, indicating a problem in the unit or connections to the speakers. 1 Power Switch: Press this switch to turn the 2. 1 on for manual operation, or to place it in the Standby mode for automatic/remote turn-on when the 2. 1 is connected to a device with a compatible trigger circuit. 2 Power On Indicator: When the word SIGNATURE is illuminated in blue, the 2. 1 is in a normal operating condition.

TRIGGER IN AC INPUT AC 12OV/60Hz 950W ¡ ¡ Speaker Outputs: Connections from these terminals should be made to the appropriate speakers in your system. TM Audio Inputs: Connect the outputs of the Signature 2. 0, or other surround processor, preamplifier or decoder to these jacks. TM £ ¢ £ AC Power Cord: Connect this plug to a wallmounted AC outlet. Due to the current draw of the Signature 2. 1, it is NOT recommended that the accessory outlets on the back of the audio/video components be used to power this product. ¢ Power Amp Trigger In: Connect this jack to the matching trigger output on a Signature 2. 0 or other compatible device to have the 2. 1 automatically turn on when the device is activated. See page 5 for additional details. 4 Signature 2. 1 Note: When making any connections between source components, processors or preamplifiers and the 2. 1, or when making any connections to speakers, be certain that both the input device and the 2. 1 are turned off. To ensure that there will be no unwanted signal transients that can damage equipment or speakers, it is always best to unplug all equipment from AC power outlets before making any connections. Modern electronic products often have a "standby" mode that may be activated even though the product may appear to be turned off. Similarly, the positive or red wire should be connected to the like terminal on the speaker. Note: While most speaker manufacturers adhere to an industry standard of using black terminals for negative and red ones for positive, some manufacturers may not adhere to this configuration. To ensure properly phased connections and optimal performance, consult the identification plate on your speaker terminals, or the speaker's manual to verify polarity. If you do not know the polarity of your speaker, ask your dealer or installer for advice before proceeding, or consult the speaker's manufacturer. Installation and Connections Connections to Speakers The final step of the installation process is to connect the amplifier to your speakers using high-quality cable. Note that one conductor of the speaker cable will have no markings or an indication of " " for negative polarity, and the other will have a red line, brand-name markings, a colored thread or some other positive-polarity indication. - The wire with the positive indication should be connected to the red terminals on both the 2. 1 and your speakers. The negative wire should be connected to the black terminal on the 2. 1 and the speakers. If bare wire is used for connections, strip approximately 3/4(20 mm) of insulation from the end of each wire and carefully twist the strands of each conductor together. Be careful not to cut the individual strands or twist them off; for optimal performance, all strands must be used. Next, loosen the knobs of the speaker output terminals far enough so that the cap moves back on its threads past the holes at the rear of the terminal. Making certain that you observe polarity by connecting the negative ( ) wire to the black terminal and the positive (+) wire to the red terminal, pass the exposed wire through the hole until the wire is visible from the bottom end. Holding the wire in place, twist the cap back so that the connection is secured. [. . . ] At the conclusion of your listening session, there is no need to manually turn off the 2. 1. When the 2. 0 or other triggering device is turned off, the 2. 1 will return to the Standby mode and the LED Indicator 3 will turn amber. Note: Always turn on the source components and processor in your system first, and turn on your amplifier last. This avoids the possibility of any turn-on pops or transients from other equipment being amplified and sent to your speakers, where they may cause damage. [. . . ]
