This symbol is intended to alert the user to the presence of non insulated "dangerous voltage" within the product's enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons. This symbol is intended to alert the user of the presence of important operating and maintenance (servicing) instructions in the literature accompanying the product. CAUTION: Risk of the electrical shock - DO NOT OPEN! CAUTION: To reduce the risk of electrical shock, do not remove cover.
CAUTION Do not open risk of electric shock CAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK, DO NOT REMOVE THE COVER. THERE ARE NO USER SERVICEABLE PARTS INSIDE. REFER ALL SERVICE TO YOUR AUTHORIZED AMERICAN AUDIO® DEALER. The lightning flash with an arrow triangular symbol is intended to alert the user to the presence of non insulated “dangerous voltage” within the products enclosure, and may be of sufficient magnitude to constitute a risk of electric shock.
Important Precautions • To reduce the risk of electrical shock or fire, do not expose this unit rain or moisture. • Do not spill water or other liquids into or on to your unit. • Do not attempt to operate this unit if the power cord has been frayed or broken. • Do not attempt to remove or break off the ground prong from the electrical cord. This prong is used to reduce the risk of elec trical shock and fire in case of an internal short.
Front Panel XLT Series 1 2 7 6 5 4 1. Indicator LEDs Channel Protect Indicator - The red Protect LED will begin to glow when the channel goes into protect mode. When the channel goes into protect mode all output for that channel will turn off. This is to protect any speakers connected to the channel. Channel Clip Indicator - This red LED will begin to flash when channel one begins to overload (clip). At this point channel one will begin to distort.

Set Up INPUTS - The XLT Series amplifier allows you to use two types of input connector per a channel, a XLR jack for balanced connections and a 1/4” female jack that will accept balanced and unbalanced connectors. Use these connections to connect the output signal from a mixer, cross-over or EQ to your XLT Series amplifier. A balanced connection is recommended for cable runs longer that 20ft. When constructing your own XLR cables follow the pin configuration describe below for proper connections.
Bare Wire Connections: (Figure 7) When connecting your speakers to the amplifier using bare wire; Unscrew the red and black caps on the binding post, be sure not to completely remove or unscrew the red and black caps. Strip back the wire insulation 1/2” (13mm). Insert the bare wire into the hole that was reveled by unscrewing the binding post cap. After inserting the wire into the binding post hole, screw the binding post cap down on the wire.
SPEAKON ASSEMBLY: You will need a pair of Neutrik Speakon® NL4FC connectors. You will also need high-quality two or four conductor speaker cable, a pair of needle-nosed pliers and a 1.5-mm Allen key to assemble the Speakon connectors to your speaker wire. To assemble the Neutrik Speakon NL4FC connector, complete the following steps: 1. Strip back 3/4-inch of the cable casing. Strip off 1/4-inch from the end of each of the conductors down to bare wire, and insert the brass fittings. See Figure 8. 2.
OPERATING MODES: Always configure your amplifier operating mode before beginning operation. If you want to change it during performance. You must decrease the gain controls to their lowest levels to protect the speakers from any popping noise. Stereo Operation - Page 15/Figure 14 details an example of a typical stereo set-up. Connect your inputs into channels one and two of the amplifier. Connect your speakers to the outputs on the rear of the amplifier.
PROTECTION: Thermal Protection - If the amplifiers operating temperature runs over 105°C (221°F) the amplifier will go into thermal protection to prevent damage from over heating. The Protect Indicator LED located on the front of the amp will light up, and the output signal will be muted. The fans will start to run at max speed to allow the amp to return to a safe operating temperature.
8-Ohm Loads: The amplifier can operate at practically any power level without risk of overheating. However, if it is pushed hard enough to continually light the “CLIP” indicator, the amplifier’s average output power can reach 150 watts. 4-Ohm Loads: If the “CLIP” indicator flashes occasionally, the amplifier is approaching its maximum long-term power capacity. If it is lit about half the time, the amplifier channel will probably go into thermal protection within a few minutes.
