Model No. _______________________________ Serial No. _______________________________ Date of purchase: _________________________ Thank you for selecting a Legacy Loudspeaker System.
- Page 4 Handcrafted Beneath the surface of Marquis’s elegant exterior lies rigid MDF construction. Interlocking joinery maximizes the strength of the cabinet parts. Polyester fiberfill is selected for internal damping. A sharp rap on the enclosure will leave you with little more than bruised knuckles. Each cabinet is impeccably finished on all exposed surfaces with select veneers.
- Page 5 Your new subwoofer has been very carefully packaged to insure that it travels to you safely. Each subwoofer is protected by a double-wall outer carton with heavy V-board corner protectors. Molded foam end caps are used to protect the elegant cabinetry, and a plastic liner is provided as waterproofing.
- Page 6 Since the human ear is rather poor at localizing radiation frequencies below 125 Hz, good results may be obtained in a variety of room placements. Careful adjustment of the convenient front panel controls will lead to seamless transition. Low frequency reinforcement occurs whenever woofers are placed near room boundaries.
- Page 7 Now, while such reinforcement might actually be beneficial at very low frequencies, excessive excitation can cause “overhang” or a droning effect at mid-bass frequencies. A way to minimize excitation of these resonances is to place your subwoofer asymmetrically relative to room boundaries.
- Page 8 The ideal conductor would have negligible resistance, inductance and capacitance. The table below shows how a few actual speaker cables measure up. Cable Ωs/ft pF/ft µH/ft 12 ga. 0.0033 0.21 14 ga. 0.0048 0.13 16 ga. 0.0079 0.18 18 ga. 0.0128 0.21 Capacitance is considered insignificant in each cable because its effect is...
- Page 9 What about phase shift due to frequency dependent travel times down the speaker cable? Measurements show that 100 Hz waves will be delayed about 20 billionths of a second behind 10 kHz waves when traveling to the end of a 10 foot speaker cable. Since the cilia of the ear requires 25,000 times longer than this just to transmit phase information, phase shifting is obviously not the primary concern when considering speaker cables.
- Page 10 Once you’ve found a place in your room, the next step is to connect the VS 12.2 to your system. There are a variety of ways this can be accomplished, all of which will be listed and explained. Option 1: Connecting the VS 12.2 using the Low Level Inputs (from preamp/processor).
- Page 11 Option 2: Connecting the VS 12.2 using a STEP One or Whisper Environmental Processor. If you are using a Legacy Audio StepOne or a Whisper controller in your system: Stereo Amplifying: In a stereo configuration, the output from the preamplifier feeds the inputs of the StepOne/Whisper Processor and the variable outputs of the StepOne/Whisper Processor feed into the stereo amplifier.
- Page 12 Option 3: Connecting the VS 12.2 using the High Level Inputs (from amplifier). A. If using the high level inputs , it is highly recommended that you connect them in parallel with your main left and right loudspeakers. B. One may decrease the low frequency demands from the main left and right speakers by connecting them to the binding posts labeled High Level Out.
- Page 13 Protection VS 12.2 features a special thermal reset to prevent damage to the internal amplifier. This is invisible under normal operation, however should your subwoofer be over-driven for long periods it will enter the “protect” mode and turn itself off.
- Page 14 Frequency: This will allow you to adjust low frequency information amplified and played by the subwoofer. The crossover frequency of the VS 12.2 is 40 - 170 Hz. so the point you set it will be somewhere in between. This feature is also operable from the remote.
- Page 15 Adjustments Be sure to sit in your normal listening area when making these final adjustments. 1. Begin by setting both the rear panel Frequency and Level controls to the 12 O’clock position. 2. Using pink noise, a warble tone centered between 50-80 Hz, or a recording with rich bass content, have someone try the phase switch in the 0°...
- Page 16 • VS 12.2 is a carefully engineered subwoofer, capable of integrating with the finest speakers. • Unlike many woofers that suffer from overshoot, VS 12.2 applies a special EMF countering circuit, which increases power handling and radically reduces low frequency distortion.
- Page 17 • Rear panel controls allow you to adjust VS 12.2’s Level, and Frequency controls. Tuning so simple, it can be done from the comfort of the couch. • VS 12.2 features automatic turn on/off when presented with an audio signal.
