IMPORTANT!!!
The T5SA outputs (LINK) send out the same signal
received on the inputs. If you use the sub-woofer
together with the d400 or one of the TITANIUM
series loudspeakers, the processor included in the
satellites filters the low frequencies. If you use
instead as satellites loudspeakers from other
brands, not provided with a built-in processor, you
need to filter the low frequencies using an external
crossover.
5. Installation and connections
1. Installation (fig. 3)
T5SA is fitted with an adapter for the use of a telescopic
loudspeaker stand for the installation of the satellite
upon of the sub-woofer. In addition, four wheels are
available on the rear panel in order to make the
transport the easiest possible.
2. Connections
T5SA is fitted with two balanced LEFT and RIGHT
inputs with XLR-F connector and two outputs with XLR-
M connector to send the signal to the satellites or to
other units. (fig. 3). According to the kind of
configuration, 1 or 2 inputs can be used (fig. 4).
- MONO CONFIGURATION (fig. 4a): the sub-woofer
receives the signal from one of the mixer outputs (LEFT
or RIGHT), which is connected only to one of the inputs.
The same signal is sent to the satellite (one or more)
and the sub + satellite system plays only the LEFT or
RIGHT part of the stereo program.
This is the most common configuration and, for what
concerns LEM speakers, it is suggested for the use with
the d400 and the models T4A, T5A, T6A, T4MA and
T5MA of the TITANIUM series.
- STEREO CONFIGURATION (fig. 4b): the sub-woofer
receives both the LEFT and RIGHT signals from the
mixer’s outputs, which are connected to both the inputs.
The two signals are sent to two satellites and the
system made of one sub + two satellites plays the whole
stereo program.
This configuration is suggested for the use of satellites
with no more than 200/300W output power. For what
concerns LEM speakers, it can be used with the T3A
model as satellite (a dedicated PRESET is available in
the sub-woofer). If you use loudspeakers from other
brands, probably you would need to reduce the sub-
woofer’s level in order to obtain the proper balance
between sub and satellites.
The input level of the incoming signal can be set using
the VOL control. If the control is rotated fully clockwise
the nominal input sensitivity (+4dB) is selected. If
needed, you can reduce the input gain turning the
control counterclockwise.
6. DPPM module - Connection panel (fig. 6)
1. Power supply cable socket.
2. ON/OFF switch with LED indicator.
3. Balanced XLR-F sockets for the input signal
connection.
4. Balanced XLR-M sockets for the signal linking to
the satellites or to a second unit.
5. Control for separating the electrical earth from that
of the chassis.
6. Two-color LED that illuminates when there’s a
signal present at the unit’s input (GREEN color) or
when the internal LIMITER is active (RED color).
7. Input level control.
8. 16-position encoder for the PRESET’s selection.
9. Air vents for the module cooling.
WARNING!!!
IN ORDER FOR THE MODULE TO WORK
CORRECTLY, IT’S VERY IMPORTANT TO KEEP THE
AIR VENTS ALWAYS FREE AND ABLE TO PROVIDE
A PROPER AIR CIRCULATION.
7. PRESETS
The PRESETS available in the T5SA have been
prepared by LEM with the support of sound engineers
and audio technicians in order to provide the sub-woofer
with different acoustical and dynamic responses suitable
for the use of different kind of satellites, for different
applications and for different tastes. Each PRESET
includes different crossover and eq filters suitable for
an optimal coupling of the sub-woofer with the d400 and
all the TITANIUM series models. In addition, 6 generic
PRESETS with different crossover filters are available
for the use of the sub-woofer with satellites from other
brands.
For the PRESET’s choice we suggest you to follow the
directions you can find below, but also to rely on the
listening and on your personal evaluations.
In the fig. 6 at the end of this manual you can find the
response diagrams of all the PRESETS included in the
T5SA.
01. d400: for the use of the sub-woofer together with
the d400 loudspeaker system.
02. d400 HOUSE: derived from the previous one,
includes the use of the MULTICOMP to enhance
the frequencies below 60Hz. Suitable for the use
with house or dance music in general.
03. 2xT3A + 2xT5SA: to be used in a STEREO
system made of two T3A loudspeakers as
satellites and two T5SA as sub-woofers (see
chapter 2. Connections and fig. 4a).
