SYMBOL Subwoofer And Center Channel OWNER’S MANUAL DESIGNED BY NEIL PATEL FOR AVALON ACOUSTICS This product is certified to meet the requirements of the European Union (EU) Electromagnetic Compatibility (EMC) Directive (89/336/EEC). Because the permanent magnets attached to the loudspeaker drivers produce magnetic fields, it is recommended that the product not be positioned in very close proximity to computer monitors or television sets.

1 Introduction The Symbol MultiChannel System reflects our passion for creating loudspeakers that capture the imagination, and accurately reproduce the three-dimensional space of modern film soundtracks as well as discreet multi-channel musical recordings.
2 Symbol Subwoofer Introduction Your Avalon MultiChannel Systems loudspeakers were shipped in heavily padded cardboard containers to ensure their safe arrival. It is recommended to save these containers for possible future use. At least two people are required to lift the Subwoofer from the shipping container. The carton may also be placed on its side and the Subwoofer slid out on its back so as not to put pressure on the grille assembly.
Signal Input Left and right balanced and single-ended inputs are provided. Most 5.1 surround sound processors provide a single subwoofer output connection. This may be either single ended or balanced. Only ONE (left or right) of these connections needs to be utilized for proper performance. Certain sophisticated installations may contain stereo subwoofer output capabilities (e.g. when using a high-end stereo preamplifier to drive a twochannel system).
3 Center Channel Mounting 1. For mounting to Symbol Subwoofer, remove four black bolts from top surface of subwoofer cabinet. 2. Locate Center Channel / Mounting Bracket assembly over the four mounting holes as shown in Figure 3.1. DO NOT DISASSEMBLE CENTER CHANNEL FROM BRACKET. 3. Tighten four black bolts with 5/32 Allen wrench until snug. 4. Connect Center Channel wiring via rear terminals. POLARITY (+ / -).
Adjustment 1. Both large black knobs must be loosened in order to tilt the Center Channel up or down. NOTE: When the pressure bearing has been loosened the Center Channel will tend to remain in its previously locked position. It may be necessary to apply pressure in order to tilt the Center Channel to a new position. 2. After adjustment of Center Channel position, make sure both knobs are snugly tightened. 3.
4 Low Frequency Fine Tuning The Symbol Subwoofer will produce prodigious quantities of low frequency energy with accurate phase and transient response. Any thickness or overhang in the low frequency presentation will be easily discernable and is the direct result of improper setup. The following guidelines should be regarded as a sound starting point; those who have extensive experience in sophisticated low frequency tuning may improvise beyond these rules of thumb.
MODE SETTINGS There are two mode settings: THEATER and HIFI. Depressing the MODE button toggles between the two settings. The appropriate LED will be illuminated, signifying the mode in use. See Figure 4.1. HIFI MODE This setting should be utilized in the vast majority of installations during music playback, or when transient speed is preferable to overall bass impact. In HIFI mode the high frequency roll off closely approximates the low frequency roll off of the Symbol satellites.

5 Maximize MultiChannel Performance These details are imperative to obtaining optimum results from your AVALON MUTLICHANNEL SYSTEMS loudspeakers. Break-in The break-in period is critical to maximizing sonic performance and should take place before other adjustments (see the discussion on page 14). The break-in should begin with three to six hours of quiet music, followed by 100 to 150 hours of loud and dynamic source material.
Toe-In Adjusting the toe-in angle of the speakers is useful in tailoring the sound to best match the characteristics of your system and listening room. When the speakers are facing straight forward, they tend to create a large, expansive sound-stage, painted with broad brush strokes. As they are rotated toward the listening position, the image becomes more compact, with increased focus, creating a greater sense of intimacy.

6 Break-in Period Your new Avalon MultiChannel Systems loudspeakers have an initial break-in period. They will not perform to their full sonic potential when first installed in your system. This is partially due to a residual polarization of the dielectric materials used in the crossover capacitors and internal wiring.1 As music is played through the loudspeakers, the electrical signal will gradually anneal these materials.
7 Care of Your Loudspeakers Cabinet (Hardwood Finish) Avalon MultiChannel Systems’ hardwood finished loudspeakers are supplied with a durable, high quality furniture lacquer. Always use a clean, lint-free cloth to clean your cabinet, and be especially careful near the loudspeaker drivers, so as not to damage the diaphragms. IMPORTANT: DO NOT use cleaners that contain ammonia, strong solvents, or abrasive materials. Use of these materials can degrade, scratch, or even DESTROY the finish.
8 Warranty Your Avalon MultiChannel Systems SYMBOL SERIES loudspeakers are warranted against defects in workmanship and materials for a period of two years from the date of first purchase to the original registered purchaser, provided that the enclosed registration card is returned to the factory within seven days of the purchase date. If the registration card is not returned within the seven-day period, this warranty is null and void, and you will not be notified of future updates.
3. Avalon MultiChannel Systems reserves the right to inspect any products which are the subject of warranty claim prior to repair or replacement. Final determination of warranty coverage lies solely with Avalon MultiChannel Systems and only products which are determined to be covered under this warranty shall be repaired or replaced by Avalon MultiChannel Systems. The customer will be informed of any delays and Avalon MultiChannel Systems will provide replacement as quickly as possible.
9 Features Advanced light weight driver diaphragm materials minimize energy storage and time-domain distortion. Smooth, wide polar response for superlative imaging capabilities. Moderate impedance characteristic allows for ideal interface with any amplifier. Crossover circuitry is hard-wired with surface-only conductors, eliminating deleterious sonic effects of printed-circuit boards. Oversize screw terminals. Careful crossover control of all magnetic field interaction.
