3. Instructions for use and installation
1. Protection and maintenance.
To avoid jeopardizing correct operation, it is best not
to position the enclosures for long periods in exposed
places (damp, high temperature, etc.), in dusty
environments or those subject to strong vibrations. On
this subject, it’s advisable to always leave the protective
grille mounted on the enclosures. In the event of
breakdown, do not open the enclosure, but contact the
nearest GENERALMUSIC Service Centre.
2. Prevention of possible interference.
Avoid installing your equipment in the vicinity of radios,
televisions, etc., since this could cause noisy
disturbance. When connecting other equipment to your
sound system, pay close attention to so-called earth-
loops, which can cause hum: in the event of
interference, try using the SHIELD switch on the unit’s
control panel.
3. Connections.
Before connecting the enclosures to the mains supply,
make certain that the current corresponds with that
indicated on the rear of the units (there is an allowance
of ±10%). Always connect the power cable to the
enclosures before switching them on and always
remove it after having switched off. Remember to
always connect or disconnect other equipment with the
enclosures off and to always switch on the mixer first,
then the enclosures: in this manner, annoying and often
dangerous peaks are avoided.
4. Connector cables.
When connecting the enclosures to the mixer, make
certain to always use only shielded signal cables made
up of two wires plus a braid/shield: the use of
unshielded cables could in fact probably cause annoying
hum and noise. Check periodically that your cables are
in good condition, correctly wired and with perfectly
efficient contacts: in fact many problems and drawbacks
(false contacts, ground hum, crackles, etc.) are caused
by the use of unsuitable or damaged cables.
4. The T5SA system (fig. 1)
T5SA is a sub-woofer that integrates in the same unit
loudspeaker, amplifier and digital processor. The
system, hosted in plywood cabinet, utilizes a long-
excursion 15” woofer with neodymium magnet and 4”
voice coil. It’s powered by the DPPM - Digitally
Processed Power Module, which includes a 500W
power amplifier for the woofer and a digital processor
able to handle all the signal processing needed for the
system control (see fig. 2):
- HPF and LPF CROSSOVER filters with the choice
between Butterworth, Bessel or Linkwitz/Riley response
and up to 48 dB/oct. slope;
- up to 15 EQ filters that can be individually set as
FULL PARAMETRIC, HI and LO SHELVING (6 or 12
dB slope) or NOTCH FILTER;
- DELAY LINE for the phase alignment;
- PHASE adjustment with 5° step through a full 360°;
- integrated protection system with high precision PEAK
LIMITERS, long term power protection and LFC (Low
Frequency Control).
2 additional PLUGINS are also available, which allows
the system performances to be further increased:
MULTICOMP (Multiband Compressor) and NOISE
GATE.
The digital processor includes 16 PRESETS, which can
be recalled directly from the system’s panel and which
include different settings suitable for the use of the sub-
woofer with different satellites and different
configurations.
T5SA, which includes the same digital processor as the
d400 and the TITANIUM series loudspeakers, has
been especially designed to provide a low frequency
extension for these systems. For this reason, the T5SA
includes some PRESETS prepared to use the sub-
woofer with the d400 and the different models of the
TITANIUM series. In addition, some other PRESETS
with different crossover filters are available for the use
of the sub with loudspeakers from other brands.
