[. . . ] x·tant x·tant (ikst`ænt, e`kstent) 1. of xtant quality that stands the test of time and the passing of fads. Standing out or above, as in outstanding, the quality or state of being original. xstans (xstantis) n present participle of xstare, to stand forth. [. . . ] Cut off excess wire and terminate the wire with spade connectors. With a small flat bladed or Philips head screw driver, loosen the terminal screw marked: Speakers. Insert each spade connector, one at a time, into the appropriate terminal. Check to make sure you've maintained proper polarity before securing each wire. Bridging All M Series amplifiers are capable of being bridged into a mono output due to the internal design of the amplifier. This feature permits the creation of a mono channel for a subwoofer or center channel. Also, bridging adds flexibility of operation. The 202m, two-channel amplifier can be used in a one channel RIGHT ­ + LEFT (mono), two channel stereo, or 3 channel ­ 2 channels stereo and one channel mono configuration. The 404m, four-channel amplifier, can be used as 2 mono channels, 3 channels ­ 2 channels stereo and one channel mono, 4 channels ­ 2 channels front and rear, 5 channels ­ 4 channels stereo and one channel mono, or 6 channels ­ 4 channels stereo and 2 channels mono. 12 Deriving the mono channel is accomplished by using the left channel positive wire as the positive speaker wire and the right channel negative wire as the negative speaker wire. It is important that a minimum 4 Ohm impedance be observed. Inputs M Series Amplifiers feature RCA inputs only. Run RCA cables from your sound source to the inputs of the amplifier. We suggest the use of high quality shielded RCA patch cords to help reduce or eliminate unwanted noise in your installation. Be sure to run the RCA cables on the opposite side of the vehicle that you used to carry the power leads to the amplifier. The input stage of the M Series amplifiers incorporates Xtant's Balanced Line circuitry. This circuitry may be "enabled" or "disabled" via the Balanced Input Mode Jumper located above the RCA input jacks. With the Balanced Line circuitry "enabled", the input sensitivity ranges from 100mV to 17 Volts. When in the "disabled" mode, input sensitivity ranges from 100mV 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. The chart below details the relationship between the jumper position and input signal level.
