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 connect

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. To prevent amplifier over heating, make sure your input signal is not clipping (Red LED indicator located a

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. AMPLIFIER FEATUR
