HTP-1 Installation and User Guide Release 1.8.1
Dolby Vision
Dolby Vision® is the one exception to the AND rule for capabilities found in the downstream EDIDs. The
Dolby Vision descriptor found in the EDID of the downstream device connected to Output 1 is the only
Dolby Vision descriptor that will be used and provided in the upstream EDID. If only one downstream
device supports Dolby Vision, it must be connected to HTP-1 Output port 1 to have Dolby Vision
recognized.
When Dolby Vision content is received, the EDID of the downstream device connected to Output 2 will
be examined for Dolby Vision support. If supported, Dolby Vision will be allowed to pass to this output. If
not supported, the output port will be disabled. When Dolby Vision content is no longer being received,
it may take up to 10-12 seconds for this output to be enabled again--the HTP-1 is making sure that Dolby
Vision content really has stopped before re-enabling the output port.
Triggers
Triggers are typically used to cause the amplifiers to turn on when the HTP-1 turns on. The HTP-1 has
four 3.5mm trigger out jacks to drive up to four amplifiers. The HTP-1 also has one trigger input that can
be used to turn on the HTP-1.
The trigger input is designed to turn on the HTP-1. Applying 12V to the trigger in will cause HTP-1 to turn
on. If you use the trigger input you should not use the remote or the front panel to turn the unit on or
off as the trigger input takes precedence.
The trigger outputs can source 50mA at 12V. They are enabled when the HTP-1 is turned on. The trigger
outputs are over-current protected by a thermistor.
Using Roon
The HTP-1 directly supports Roon. It is a “Roon Ready” device. Roon provides a music service designed
to support a locally stored archive of music which includes high quality formats like 96kHz-24 bit and
192kHz. Roon is a service that you must subscribe to. The HTP-1 takes the role of an output device in
your Roon system. You can play stereo audio through Roon.
Please refer to the release notes found in the help section of the web server for the latest information
about the status of Roon.
When you have a Roon subscription, there is a device known as a Roon Server in the system. This can be
a program on your PC. The Roon Server knows where your music is. There must also be a device that can
navigate your music collection and press the play button. The HTP-1 does not perform this role. The
Roon program on a PC can take on this role. The Roon app on your phone can also take on this role.
With your Roon controller ready, select the Roon input on the HTP-1. With the Roon input selected, the
Roon audio is routed through the HTP-1. You can enable upmixing as you desire, or enjoy the pure 192k
sample rate (as available) if preferred.
