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.
