3.5 PSUTS
This subwoofer has two 6” reflex coupling loudspeakers and 8 Ohm overall
impedance.
PSUTS
subs are used together with a variable number of PSUT1
modules and can be installed both on the floor or on the wall (better if close
to the ceiling) by means of dedicated accessories. It is also possible to screw a
PSUT1 speaker or a cluster of them directly on a PSUTS.
PSUTS subwoofers have an internal high-pass filter (12 dB per octave) and can
be parallel connected to PSUT1 satellites through the same amplifier channel
to form a single full-range system, duly “crossed” and perfectly tuned in the
crossover band (centred on 160 Hz).
4. OPERATING INSTRUCTIONS FOR UT ACTIVE STACK SYSTEMS
4.1 Description of the elements in an active stack
We have already covered the application of the PSUTBASE/A subwoofer
and PSUT8TE - PSUT8AE column speakers for floor-standing, compact,
active systems configurations (more commonly known as active stack
systems) in paragraphs 3.1 and 3.2.
The UT active stack systems are made from four basic elements:
PSUTBASE/A
Active subwoofer with butterfly hinges and
direct-contact
output
socket
on the top for power
feeding to the module above
PSUT8-ST70
Extension element with direct-contact
input
plug
on
the bottom and
output
socket
on the top for feeding
power from the lower element to the upper one
PSUT8AE
“ADDITIONAL ELEMENT” passive sound column with
direct-contact
input
plug
on the bottom and
output
socket
on the top, to receive power from the lower
element and feed it to the module above
PSUT8TE
“TOP ELEMENT” passive sound column with butterfly
hinges and direct-contact
input
plug
on the bottom,
to receive power from the lower element
4.2 Composition of active stack systems
UT
Active Stack 1_1_mono
systems (where “1_1” stands for 1 column
speaker and 1 active subwoofer) are composed of 1 PSUTBASE/A +
1 PSUT8-ST70 + 1 PSUT8TE.
This system can be doubled to obtain a traditional left/right configuration
called UT
Active Stack 1_1_stereo
.
UT
Active Stack 2_1_mono
systems (where “2_1” stands for 2 column
sp 1 active subwoofer) are composed of 1 PSUTBASE/A +
1 P 1 PSUT8TE.
The system can be doubled to obtain a traditional left/right configuration
called UT
Active Stack 2_1_stereo
.
