EMA 255

Premošćeni priključci zvučnika

Pojačalo EMA može se premostiti za mono konfiguraciju. Time se pojačalo može koristitis jednim ili dvama subwoo- ferima ili uređajima u srednjem rasponu frekvencija. U toj konfiguraciji pojačalo spaja desni i lijevi kanal u jednokanalni izlaz (mono izlaz).

Napomena:

Pojačalo može dodati informacije signala iz desnog i lijevog kanala samo ako su obavljeni desni i lijevi RCA spojevi.

Oprez:

U premošćenom krugu opterećenje pojačala mora izno- siti najmanje 4 Ω. Niže opterećenje uzrokovat će pre- grijavanje i isključivanje pojačala te može uzrokovati trajna oštećenja.

Podešavanje vrste i raspona frekvencijskih prolaza

Kod zvučnika EMA 255 mogu se podesiti vrsta frekvencijskih prolaza (tj. »Low Pass« ili »Hi-Pass«) te željena ulazna frekven- cija. Na primjer, ako je potrebno priključiti dva subwoofera, potrebne su postavke niskoprolaznog filtra (sl. 3). Ulazna frekvencija ovisi o frekvencijskom rasponu zvučnika (vidi preporučeni frekvencijski raspon zvučnika).

Visokoprolazna frekvencija

Na postavci od 80 Hz pojačalo ima frekvencijski raspon od 80 Hz do 30.000 Hz.

Regulacija niskoprolazne frekvencije

Regulacija je aktivna ako je prekidač u položaju »Low-Pass« i omogućava namještanje željene ulazne frekvencije.

Primjer:

Na postavci od 150 Hz pojačalo ima frekvencijski raspon od 10 Hz do 150 Hz.

Pojačanje niskih tonova

Regulacija pojačanja niskih tonova služi za podešavanje reakcije niskih tonova pojačala.

Područje podešavanja je od 0 dB / +6 dB / +12 dB.

Please read these operating instructions before using the equipment for the first time.

Recommendation

The performance of an amplifier can only be as good as its installation. A correct installation increases the overall perfor- mance of your car sound system. The EMA amplifier should be installed by a trained person. If you would to install it your- self, please read these installation instructions very carefully and allow yourself sufficient time for the installation.

In conclusion, allow us a few words about the topic of health protection:

During the playback of music in your vehicle, please consider that continuous sound-pressure levels above 100 dB can lead to permanent damages to the human ear and even to loss of hearing. Using today's high-performance systems and loudspeaker configurations allows for reaching sound- pressure levels above 130 dB.

Safety notes

Please observe the following safety notes during the installation and connection.

–Disconnect the negative terminal of the battery before carrying out installation and connection work.

–Observe the vehicle manufacturer's safety instructions (regarding airbags, alarm systems, trip computers, vehicle immobilisers).

–When you drill holes, ensure that you do not damage any vehicle components.

–The cross section of the plus and minus cable may not be less than 6 mm2.

–Use cable glands for holes with sharp edges.

–An incorrect installation can result in malfunctions of the electronic vehicle systems or your car sound system.

Installation and connection instructions

With respect to accident safety, the EMA 255 must be secured in a professional way.

When selecting the installation location, select a dry loca- tion that offers sufficient air circulation for cooling the amplifier.

The EMA 255 must not be installed on rear shelves, rear seats or other locations that are open to the front.

The installation location must be suitable to accept the ac- companying screws and provide a firm support.

The amplifier power cable must be fitted with a fuse no more than 30 cm from the battery to protect the vehicle battery in case of a short circuit between power amplifier and battery. The fuse of the amplifier protects only the amplifier, not the vehicle battery.

Use loudspeakers with 2 - 4 Ω impedance (see table or in- stallation drawing). Observe the maximum power handling capacity (music output). Do not connect loudspeakers to earth, use only the referenced terminals.
