AIMING THE DPT (AMC720, AMC 760 and AMC800 only)
In addition to providing an extremely clean wide range response, the DPT have the added
feature of an adjustable waveguide (in 45 degree increments). This unique Snell feature
provides the opportunity to toe-in conventionally mounted in-wall systems or compensate for
the less than ideal placements that occur in the real world. This feature will greatly improve
imaging.
To adjust the DPT rotation,
remove the four wood
screws with a 5/64” allen
driver and rotate the driver
to the desired positions.
MULTIPLE DISPERSION PATTERNS (AMC 800 only)
The AMC800 can be set to reproduce two dispersion patterns. You determine the dispersion
pattern by selecting which of the two bass units will operate as the midbass driver. The
dispersion pattern can be seen as an ellipse, whose length is a line perpendicular to the
tweeter/midbass combination as shown below.
Three examples of how the DPT waveguide tweeter
can be rotated in 45° increments.
