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.

Recommendation

The performance of an amplifier can only be as good as its in- stallation. A correct installation increases the overall perform- ance of your car sound system. The EMA amplifier should be installed by a trained person. If you would to install it yourself, 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 instal- lation and connection.

–Disconnect the negative pole of the battery! Observe the safety notes of the vehicle manufacturer.

–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.

Audio inputs (see Fig. 3)

You can select between 2 different audio inputs;

–Cinch (RCA)

–Hi level (loudspeaker connections)

Use only one of the audio inputs; otherwise, it may lead to audio interferences.

The preamplifier outputs are connected to the cinch (RCA) sockets 1via a shielded sound cable.

With control via the loudspeaker outputs, the input connec- tions of pos. 2/3are fed to the closest loudspeaker cables (front or rear) on the left and right. They are separated and connected to the input connections. The polarity of the + or - connections must be observed. Bridge output stages (BTL) can also be connected directly without an additional adapter.
