Operating Voltage (AC Mains) -
On the rear panel will indicate the correct AC mains voltage. Connecting to the wrong voltage is dangerous and may damage the
amplifier. Always be sure the source voltage for your areas matches the required voltage for your amplifier.
Gain Controls -
The gain controls are located on the front panel and are calibrated in 2dB of attenuation from full gain. It is best to a d j ust the amplifier so no
“hissing” is heard from speakers with no music being played, this will ensure the lowest possible distortion d u ring normal operation.
AMPLIFIER FEATURES:
THRU :
THRU will allow the user to daisy-chain one amplifier’s signal input into another amplifier. Plug the signal source outputs into the first amplifier’s input, patch
from the amplifier’s THRU jacks to the next amplifier’s input, and so on, daisy-chaining as many amplifiers as there is no excessive level loss.
LED INDICATORS :
Each channel has six LEDS. Four LEDs indicate signal level activity; two green LED and two yellow LED. One red LED indicates signal clipping
(For XT-500 & XT-600 only has 5 LEDs). One red LED indicates protections mode for shorts / overload. Both channels will also share the center green LED that
indicate the amplifiers operating mode.
FUNCTION INDICATORS :
These green/white/green LED indicators detail the amplifiers current operating mode (Parallel, Stereo, Bridge).
INPUT GAIN SWITCH :
The input gain switch will change the volume or output of an amplifier. In the rear panel of the XT series, you can find the switch to select the
desired input gain: for the XT-900 & XT-1250 is 26dB, 32dB or 0.775V selection, and for the XT-500 & XT-600 is 1.44V, 1V or 0.775V selection. It is set at the factory to
0.775V for rated output into 8 ohms. Before you change the input gain, please turn off the amplifier and disconnect its power cord from the AC mains power receptacle
to avoid danger.
