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. Repeat this process if distortion (input clip) continues. [. . . ] 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. Move the jumper to the 0, ­10 or ­20 dB position to decrease the gain. The input circuitry operates similar to a line driver by increasing the signal level when placed in the +10 and +20 dB positions. The following chart illustrates this function: INPUT VOLTAGE MULTIPLYING FACTOR INPUT JUMPER POSITION MULTIPLYING FACTOR OPTIMIZING CIRCUITRY The 301a incorporates an optimizing circuit which allows the amplifier to produce maximum power (300 Watts) into either a 4 or 2 speaker load. 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.

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.
