Standing out or above, as in outstanding, the quality or state of being original. xstans (xstantis) n present participle of xstare, to stand forth. [. . . ] The amplifier is shipped with a 90 Hz SIP installed, 13 other frequencies are available from your Xtant Dealer. Refer to page 7 of this manual for a list of the available frequencies. Noise Gate: Provides deep muting when no musical signal is present. Features include adjustable threshold and bypass switch. Balanced / Floating Input: When enabled, this circuitry helps to eliminate "system noise" associated with "ground-loops". Modular Expansion Port: All Xtant amplifiers are supplied with a modular port used for docking any of Xtant's signal processing modules. Protection Circuitry: Both Thermal and Overcurrent protection has been incorporated into all Xtant amplifiers. In the event of a problem, the amplifier will reduce its power to maintain operation. Status LEDs: Four LEDs, visible through the cover, indicate operational status of all Xtant amplifiers. The red LED illuminates when the amplifier is "ON", the green LED indicates when the noise gate is open, the yellow LED indicates that overcurrent protection is employed and the orange LED indicates that the thermal protection circuit is operational. PASSIVE Outputs: The RM8 Resistor Module is designed to activate the "passive speaker terminals. " It provides 8dB of attenuation for speakers connected to these terminals. RM4, RM12 and RM16 also available. 5 Xtant 604X SPECIFICATIONS Frequency Response: Number of Channels: Watts per Channel @ 4: Watts per Channel @ 2: Bridged Mono @ 4: Recommended Load: Distortion (THD): Signal to Noise Ratio: Damping Factor: Input Sensitivity: 5 Hz to 50 kHz +/­ 1 dB 4 4 x 75 4 x 150 2 x 300 >2 Stereo / >4 Bridged < . 04% > 100 dB > 200 @ 100 Hz with 4 load 100 mV to 8. 5 V RMS Unbalanced Source 100 mV to 17 V RMS Balanced Source Measured: 20 Hz to 20 kHz at rated power, all channels driven 4 Measured: A-weighted in 20 kHz noise bandwidth @ 1 volt sensitivity Input to Line Output Gain: 0 dB +/­ 20 dB, Selectable in 10 dB steps On-Board Crossover: Module Port(s): Balanced Line: Passive Outputs: Power Supply: Operational Voltage: Fusing Requirement: Size (L xW x H): Warranty: SEE PAGE ELEVEN OF THIS 12/24 dB/Octave Butterworth 4 ­ Accessory 2 ­ On Board 2 Channels; RM8 provided Fully Regulated, PWM 11 to 15 Volts 120 Amp 23. 63 x 8. 875 x 2. 145" Limited 4 Year Parts and Labor MANUAL FOR COMPLETE D E TA I L S 6 ON-BOARD ELECTRONIC CROSSOVER All Xtant "X" series amplifiers have on-board, two-way electronic crossovers. Xtant 3 and 4 channel models feature two independent two-way crossovers. Each crossover is tied to a set of inputs and controls the frequency range of the associated amplifier. Independent frequency selection is provided for both the High and Low Pass sections. A set of selectable RCA line outputs (to feed additional components) are included with each crossover. In addition, each crossover features four on-board header jumpers (two for the amplifier and two for the RCA line outputs) which allow you to select Bypass (Full Range), High Pass, and/or Low Pass modes. The "X" Series models offer an additional Band Pass selection. When chosen, the Band Pass selection is available via the Low Pass jumper position for the RCA line outputs. The following Frequency Modules (SIPs)* are available from your Xtant Dealer: 50 Hz, 70 Hz, 80 Hz, 90 Hz, 120 Hz, 150 Hz, 300 Hz, 500 Hz, 700 Hz, 1 kHz, 3 kHz, 4 kHz, and 5 kHz. Please refer to the Installer's Reference (insert) for the Frequency Module receptacle location and chart of frequency/SIP value code numbers * SIP: an acronym referring to multiple resistors in a Single In-Line Package 7 OPTIONAL ACCESSORY MODULES Xtant optional accessory modules are easily and quickly installable by your Authorized Xtant Dealer. The upgrade modules snap into place on the amplifiers PC board when the top of the unit is removed.
