Anleitung Zusammenfassung
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 frequencies present at the inputs to feed these channels. This is useful for systems utilizing outboard active crossovers or requiring full-range reproduction this channel pair. “BP” (High-Pass): Configures the filter to attenuate frequencies below the indicated filter frequency AND above the Channel 1 & 2 Filter Frequency, at a rate of 12dB per octave. This is useful for connection of mid-bass or mid-range speakers in a tri-amplified system. “HP” (High-Pass): Configures the filter to attenuate frequencies below the indicated filter frequency at a rate of 12dB per octave. This is useful for connection of component speakers or coaxials to this channel pair in a bi-amplified system. Subwoofer Channel Filter: 12dB/octave or 24dB / octave, Low-Pass only “Off”: Defeats the filter completely, allowing the full range of frequencies present at the inputs to feed this channel. This is useful for systems utilizing outboard active crossovers. “12dB” (Low-Pass): Configures the filter to attenuate frequencies above the indicated filter frequency at a rate of 12dB per octave. This is useful for connection of subwoofers in a bi-amplified system. This shallower slope gently attenuates high-frequencies from your subwoofer signal and is often well-suited for sedans and coupes with trunks. “24dB” (Low-Pass): Configures the filter to attenuate frequencies above the indicated filter frequency at a rate of 24dB per octave. This is useful for connection of subwoofers in a bi-amplified system. This sharper slope more aggressively removes high-frequencies from your subwoofer signal and is often well-suited for SUV’s, wagons and hatchbacks. 2) “Filter Freq. (Hz)” The filter frequency markings surrounding these rotary controls (one in each Channel Section) are for reference purposes and are generally accurate to within 1/3 octave or better. If you would like to select the filter cutoff frequency with a higher level of precision, consult the chart in Appendix B (page 15). Tuning Hint: If you are using the XD700/5 to drive a subwoofer system (“LP” mode), and component satellite speaker systems (“HP” mode), 80 Hz is a good baseline “Filter Freq. (Hz)” setting. After properly adjusting the “Input Sens.”, as outlined in Appendix A (page 14), you can fine tune the “Filter Freq. (Hz)” control to achieve the desired system frequency response. REMOTE LEVEL CONTROL (OPTIONAL) With the addition of the optional Remote Level Control (HD-RLC), you can control the volume of the subwoofer channel (Subwoofer Level) or of the entire XD700/5 from the front of the vehicle (Master Volume). The HD-RLC connects to the jack labeled “Remote Level Control” on the Connection Panel of the amplifier using a standard telephone cable (supplied with the HD-RLC). If desired, multiple XD (and HD) amplifiers can be controlled from a single HD-RLC controller using a simple phone line “splitter” and multiple phone cables. When connected to the amplifier, the HD-RLC operates as follows. At full counter- clockwise rotation, the audio of the selected channels will mute completely. At full clockwise rotation the level will be the same as if the HD-RLC was not connected at all. In other words, it operates strictly as a level attenuator. “Remote Level Mode” Switch: This switch allows you to assign the operation of the HD-RLC to the entire amplifier or only the subwoofer channel. In the “All” position, the HD-RLC knob will affect all channels equally. In the “Sub Ch.” position, only the level of the subwoofer channel will be affected by the HD-RLC knob. SPEAKER OUTPUTS The XD700/5’s speaker outputs are designed to accept 16 AWG - 8 AWG wire. To connect the speaker wires to the amplifier, first back out the set screws on the top of the terminal block, using the supplied 2.5 mm hex wrench. Strip 1/2 inch (12 mm) of insulation from the end of each wire and insert the bare wire into the terminal block, seating it firmly so that no bare wire is exposed. While holding the wire in place, tighten the set screw firmly, taking care not to strip the head of the screw. Each pair of the XD700/5’s main channels are designed to deliver power into speaker loads equal to or greater than 2 ohms when using a “stereo” configuration and speaker loads equal to or greater than 4 ohms when using a “bridged” configuration. The subwoofer channel is designed to deliver power into subwoofer loads equal to or greater than 2 ohms. Speaker loads below 2 ohms nominal per channel (or 4 ohms bridged) are not recommended and...
