PSB Speakers VS400 - Manual (Page 11)

ensure that the diaphragms of the speakers on both channels move forward and
backward together (“in-phase”), rather than in opposition (“out-of-phase”). In-phase
connection provides maximum clarity and bass, while out-of-phase connection
results in frequency cancellations and produces thinner and less distinct sound –
with less bass, vague vocal quality, and no solid center image. To help ensure the
proper connection, the two separate conducting wires in a standard two-conductor
speaker cable are coded in one way or another to be distinguishable from each
other. (The jacket of one wire may be ribbed or marked with “+” signs, or one wire
under the insulation may be a different color from the other.) Use this wire-coding,
together with the amp/receiver and speaker color-coding, to be sure you are
connecting the same wire of a given pair to a like-coded terminal at both ends of your
connection. Assure all wiring terminals are tightened firmly but be careful not to over-
tighten and damage the connectors.
VI. GRILLES
Installing and Removing
Grilles for the VS models are magnetically attached. Bring the grille up to the
approximate position and it should snap into place. Confirm that all magnetic
catches have aligned and that the grille is well seated around its full perimeter.
Bare Wire Connection Banana Plug Connection Spade Plug Connection
Loosen knurled nut.
Insert wire through
hole and tighten nut.
Takes wire sizes up to
8 gauge. Insert banana plug into
the top of the nut.
Ensure the hex nuts
are tightened to
prevent rattles. Loosen nut. A
1/4"(6mm) or
5/16"(8mm) spade will
fit on the narrower
section of the post.
Tighten the nut.
