    The materials in your new Prodigy speakers are of the highest quality and will provide years of enduring enjoyment and deepening respect. All trim pieces are constructed from selected hardwoods.

  • Page 7: Operation

    Substantially impaired performance or severe damage may occur to an Prodigy speaker if oper- ation is attempted from an incorrect AC power source. WARNING! The power cord should not be installed, removed, or left detached from the speaker while the other end is connected to an AC power source.

  • Page 8: Single-Wire Connection

    Connect one set of wires to the upper set of binding posts which connect to the panel of the Prodigy. Then connect a second set of wires to the lower binding posts which connect to the woofer. Next, connect both sets of wires to the appropriate terminals on your amplifier.

    In long rooms, naturally, that relationship changes. The distance between the speakers will be far less than the distance from you to the speaker system. However, in a wide room, you will still find that if...

    Enjoy Yourself The Prodigy is a very refined speaker and benefits from care in setup. With these tips in mind you will find, over your months of listening, that small changes can result in measurable differences.

    Reflective Surfaces (near-field reflections) The hard surfaces of your room, particularly if close to your speaker system, will reflect some waves back into the room over and over again, confusing the clarity and imaging of your system. The smaller sound waves are mostly affected here, and occur in the mid and high frequencies.

  • Page 17: Electrostatic Advantages

    Since the diaphragm of an electrostatic speaker is uniformly driven over its entire area, it can be extremely light and flexible. This allows it to be very responsive to transients, thus perfectly tracing the music signal.

  • Page 18: Full Range Operation

    The Prodigy uses no crossover networks above 250 Hz because they are not needed. The Prodigy consists of a single, seamless electrostatic membrane reproducing all frequencies above 250 Hz simultaneously. How is this possible? First we must understand that music is not composed of separate high, mid and low frequency pieces.

    This proprietary coating insulates the stator to three times its actual needed working voltage and gives the Prodigy a wide margin of safe operation. In addition to the electrical insulation properties, this coating also provides the Prodigy with a durable, attractive finish that dampens the steel to prevent ringing.

    However, Lodge had no intention for his device to reproduce music because in 1898 there was no way to amplify an electrical signal! As a result, his speaker had nothing to offer over the acoustical gramophones of the period. It was not until 1906 that Dr. Lee DeForrest invented the triode vacuum tube.

    Impedance. The total opposition offered by an electric circuit to the flow of an alternating current of a single frequency. It is a combination of resistance and reactance and is measured in ohms. Remember that a speaker’s impedance changes with frequency, it is not a constant value.

The abbreviation for total harmonic distortion. (See Distortion.) TIM. The abbreviation for transient intermodulation distortion.
