Thank you for your purchase. The speakers in our Alpha series are designed to
deliver high performance in many uses, and we hope they add much enjoyment
to your listening life.
I. SIMPLE STEPS FOR A QUICK START:
A. Be sure power to your amplifier/receiver and other electronics is off before
making connections.
B. Install bumpers, adjustable levelers or spikes in the feet.
C. Position your main speakers, as symmetrically as possible, at a
comfortable listening distance-slightly closer to each other than they are
to you. (For surround speakers, see later instructions.)
D. Using standard 18 gauge (1.0mm dia) lamp wire or better, connect the
Red (positive) terminal on each channel of your amp/receiver to a Red
terminal post on that channel's speaker, and the Black (negative) terminal
to a Black terminal post on the speaker.
E. Setting the volume low beforehand, turn on your associated equipment,
find a comfortable listening volume-and enjoy your favourite audio and/or
video selections.
F. After you have settled in with your speakers, read through this booklet. Be
sure to read "Protecting Your Investment."
II. MORE ON SPEAKER POSITIONING
A. Main Speakers:
The three factors to adjust according to your own tastes-keeping in mind that
you are the judge and the one(s) to be satisfied-are:
1. The closer you place speakers to the boundary surfaces of your
room, the greater the proportion of bass in their overall sound. This is
due to the enclosing, "focusing" effects of nearby surfaces on longer-
wavelength (lower) frequencies. Positioning the speakers near the
intersection of two surfaces (wall and wall, wall and floor, or wall-and
ceiling) will produce more apparent bass than placement near a single
surface. The greatest proportion of bass is delivered by placement near
three intersecting surfaces-in a room corner near the floor or ceiling,
where the convergence of the two walls and the floor/ceiling produces an
amplifying effect that is a bit like that of a megaphone. And the least bass
comes from placing a speaker away from all boundaries. Your own tastes
should decide what proportion of bass response seems right in your room.
2. Distances of speakers from the walls can make great differences in
the number, strength, and particular frequencies of secondary
reflections-changing frequency-balance, sonic spaciousness, and
definition. Most listeners prefer their speakers at least a few inches from
