User manual XTANT X210 TECHNICAL DATA REPORT

[. . . ] If your customer desires max output, don't be afraid to adjust the Input Gain Select to +20 and turn the output gain pot wide open (full clockwise rotation). If you should encounter distortion (input clip), turn the amp off via the Remote TurnOn jumper and reset your Input Gain Select to +10. Return the Remote Turn-On jumper to the "enable" position and audition the system. The object is to pass as much input signal as possible without over-loading the input stage. [. . . ] The Orange LED indicates that an over-heating condition exists and will turn the amp's output power down to maintain uninterrupted operation. The Orange LED will light if the heatsink temperature exceeds rated spec due to a blocked air intake or exhaust opening. If the fan should fail, the Orange LED will also light. INPUT SENSITIVITY The input stage of the 301a incorporates Xtant's Balanced Line circuitry. This circuitry may be "enabled" or disabled ("defeat") via the Balanced Input Mode Jumper located above and to the left of the RCA input jacks. With the Balanced Line circuitry "engaged", the input sensitivity ranges from 100 mV to 17 Volts. When in the "defeat" mode, input sensitivity ranges from 100 mV to 8 Volts. Input sensitivity is adjustable in 10 dB steps via the Input Gain Select jumper located above the Balanced Input Mode Jumper. Each of the five jumper positions correlate to a specific range of input signal levels. A chart detailing jumper position to input signal levels is located on the opposite side of this "Installer's Reference". The amplifier is shipped with the Input Gain set at the +10 dB position. If you do not know the output signal level of the head unit and you want to change the factory setting, simply move the jumper to the +20 dB position to increase the gain. Failure to "enable" the Balanced Line may result in damage to the head unit. The Balanced Line circuitry also helps eliminate noise (ie alternator whine) induced into the signal cables. If you are experiencing a noise problem, simply "engage" the Balanced Line circuitry. If the problem continues, call Xtant Technologies' Customer Service at 602·970·9900 for assistance. · · · · · · · · · Red LED on. tor Accessory module not installed properly Be sure "key" on module connecand port are aligned when installing module. Induced noise / ground loop "Enable" Balanced Input SERVICE JUMPER This jumper breaks the connection of the Remote Turn-On lead. It has been provided to allow easy "turn-off" and "turn-on" of the amplifier during the fine-tuning process. With the amp playing, simply move the Remote Turn-On jumper to the Amp-Off position, make your adjustments and move the jumper to the Enable position to turn the amp back on. · · · · · · · · · Alternator/System Noise xtant technologies · · · · · · · · · 7 6 7 6 SOUTH 4 6T H STREET.
