HTP-1 Installation and User Guide Release 1.8.1
The HTP-1 can support many different configurations of upper speakers. The upper speakers can be
“high,” which are mounted on the wall, or “top,” which are on the ceiling firing down.
Dolby® Enabled speakers are also supported. Dolby Enabled speakers have two independent drivers
with two independent inputs. One of the drivers points up, so that sound will reflect off the ceiling and
sound like a Top speaker. Dolby Enabled speakers are convenient in that they are integrated with typical
front firing (Front or Surround) speakers. They work best when the ceiling is flat, reflective to sound and
no greater than 10 feet in height.
Dolby content is typically authored with the upper level speakers in the ceiling. DTS® and Auro-3D®
content is typically authored with the speakers High on the walls. The HTP-1 remaps the source material
to match the user-defined speaker configuration. The following table explains the Upper level speaker
options:
Upper Level Speaker
Count/Configuration
Details, Suggestions, and Restrictions
2 Top: middle or top front
pair only
Dolby® content is often authored assuming only the top
middle speaker pair. If only two upper speakers are available,
top middle is the best bet.
If your speakers are here, then use this setting. But this is not
a preferred speaker arrangement.
4 Top: 4 ceiling mounted
(down firing speakers,
front and rear left and
right)
This is a Dolby® preferred speaker layout. Other formats also
support this configuration. Auro3D™ will work, but this is not
optimal for Auro3D™.
4 High: 4 wall mounted
high speakers, front and
rear, left and right
This is a DTS® preferred configuration. Other formats also
support this configuration, but it’s not optimal for Auro3D™.
See Top Middle vs High Side.
4 Mixed: front high, rear
top or front top and rear
high
If your speakers are most easily set in such a mixed
arrangement, HTP 1 can be configured to map the signal to
these configurations.
6 Top: front, middle and
rear
Ideal for Dolby. Acceptable for DTS. OK for Auro-3D®. See
Top Middle vs High Side.
6 High: front and rear are
high on the wall
The signal for the upper middle pair is actually the “top
middle" for Dolby, so the pair is separated more widely than
Dolby suggests. But this is best for Auro-3D®. See Top Middle
vs High Side.
