This is useful for connection of component speakers or coaxials to this channel pair in a bi-amplified system. “x10” (High-Pass): Configures the filter to attenuate frequencies below a frequency TEN TIMES HIGHER than the indicated filter frequency at a rate of 12dB per octave. This is useful for connection of tweeters to this channel pair in a tri-amplified system. Channel 3 & 4 Filter: 12dB/octave High-Pass or Bandpass Filter “Off”: Defeats the filter completely, allowing the full range of freq

If the channel pair is operating in stereo, it is only necessary to measure one channel. If bridged, make sure you test the voltage at the correct connectors (L+ and R–). 8) Increase the “Input Sens.” control until the target voltage is observed with the voltmeter. 9) Once you have adjusted the XD600/6 to its maximum low-distortion output level, reconnect the speaker(s). The “Input Sens.” controls can now be adjusted downward if the amplifier requires attenuation to achieve the desired system ba

For precise filter frequency information refer to Appendix B (page 15). Multi-Amplifier SYSTEMS Using the “Preamp Outputs” of the XD400/4, it is easy to configure many different multi-amplifier systems. The most common type involves the addition of a subwoofer amplifier, such as the XD600/1. Common configurations of such a system are described below. Bi-Amplified System with one XD400/4 in four-channel mode and a separate subwoofer amplifier This configuration requires that the separate subwoofe

When bridged, each channel produces signals of equal magnitude, but opposite polarity. The combined output of the two channels provides twice the output voltage available from a single channel. The XD400/4 has been designed for bridging of its channel pairs without the need for input inversion adaptors. To bridge a pair of channels, use the “Left +” and “Right –” speaker connectors only (the “Left –” and “Right +” remain unused). When bridged, each channel will deliver optimum power into a 4 ohm

7) Securely mount the amplifier. 8) Connect the positive and negative power wires to the amplifier. A fuse near the amplifier is not necessary if the XD200/2 is the only device being run from the fused main power wire. If the fused main power wire is shared by the XD200/2 and other amplifiers or devices, fuse each amplifier/device within 12 inches (30 cm) of wire length, via a fused distribution block or multiple individual fuse blocks/on-board fuses. 9) Connect the remote turn-on wire to the am

4. Connect the REMOTE terminal to an external switch for positive 12V turnon-off. This may be connected to the head unit power antenna lead. Installation Precautions This amplifier comes complete with all mounting harware required. Please remember that this is a high-power unit, which generates considerable electrical energy and heat. Therefore, be sure to install the unit in a place with sufficient airflow, a minimum of dust, and no moisture. Allow enough space around the cooling fins to permit

Should this occur, the PROTECT LED will be illuminated. At that time, it is important that you check to determine what has caused the protection circuitry to become activated. If the amp shut off because of a thermal overload, allow it to cool down before attempting to restart. If the shutdown occured because of an input overload, or speaker short circuit, be sure to correct these conditions before attempting to restart the amp. To reset the amp, turn the REMOTE power off and on again. Power LED

If hiss/noise disappears, go on until the faulty/noisy component is found. • It is best to set the amplifier's input level as insensitive as possible. The best subjective S/N ratio is obtainable this way. Try to drive as high a signal level from the head unit as possible. Protection LED comes on when the amplifier ispowered up. • Check for shorts on speaker leads. • Check that the volume control on the head unit is turned down low. • Remove speaker leads, and reset the amplifier.
