Functions
• Active Loudness
The “active loudness technology” (physiological volume control) used in TP
TUBE loudspeakers are unique to these products.
In TP TUBE loudspeakers there are used a very subtle, acoustic natural
process that dynamically regulates the amount of “boost” depending on the
frequency and level, after the so called Fletcher-Munson curves.
“Active loudness” level can be changed with the included TPlay - CD / USB.
The function can, if desired, be turned off by a switch on the panel on the
cabinet rear. (Cable Connections page 13 / fig.2)
• Auto-leveling input
TP TUBE loudspeakers can be used with any audio source
(standard line-level professional line level, power amplifier output level.)
With first time use or after “reset”, the unique “auto-leveling input” function
adjusts the input gain to suit most amplifiers (from 5W and up)
If it is necessary to connect the speakers to a line-level output, the start level
is set using the CD / USB.
(read more in the section “Customize settings with TPlay”)
• Limiters
TP TUBE loudspeakers are protected by a digital limiter, which provides
protection of the speaker units from being destroyed by limiting the output
level.
This means that it is impossible to destroy the devices, playing too high.
