HTP-1 Installation and User Guide Release 1.8.1
The HTP-1 also supports the Dirac Live Bass Control system. This includes an alternate bass manager.
The Dirac system measures the room and automatically suggests crossover frequencies. These can be
adjusted in the Dirac Live program with reference to the measured capabilities of the speakers. The
crossover controls are not displayed on the speaker page when the Dirac Live bass manager is active.
Audio systems support multiple subwoofers because low frequencies can produce standing waves in a
room which causes dead spots. Using several subwoofers is a common technique to minimize this effect.
Dolby Enabled speakers point up toward the ceiling to reflect the sound down. They act as “top”
speakers. Dolby enabled speakers have a cutoff frequency like small speakers.
The HTP-1 bass manager also routes the subwoofer signal through a lowpass filter. The cutoff frequency
of this filter is set to the highest cutoff frequency set in the speaker configuration pane. If all of the
speakers are large, then an 80Hz cutoff is applied to the LFE channel. This is not the case with the Dirac
bass manager.
According to Dolby rules, the LFE (Low Frequency Effects) channel of a surround sound signal is not
reproduced when there is no subwoofer in the system.
The Sound Enhancement page describes a
​
“Bass Reinforcement” feature
​
provided by the HTP-1 bass
manager.
When the Dirac Live Bass Control filter is activated, the regular HTP-1 bass manager is disabled. This is
indicated near the top of the speaker configuration page and on the Dirac button.
