Plus / minus connection
- We recommend a minimum cross section of 6 mm
- Route commercially available plus cables to the
battery and connect via fuse holder.
- Use cable glands for holes with sharp edges.
- Securely fasten commercially available minus cables
to a noise-free earth point (chassis screw, chassis
metal) (not to the minus pole of the battery).
- Scrap the contact surfaces of the earth point until
they are bright and grease with graphite grease.
Integrated fuses (Fuse)
The fuses integrated in the amplifi er (Fuse) protect the
power amplifi er and the entire electrical system in case
of an error. If a replacement fuse is used, never bridge
fuses or replace them with a type with higher current.

Loudspeaker connections
Note:
To avoid damaging the amplifi er in operation, all lou-
dspeaker connections must be occupied according to
Fig. 4, 5, 6.
+12V
Remote connection of the amplifi er with switchable +12 V
voltage source.
This allows the amplifi er to be switched on and off using
the on/off-switch of the radio device.

Level control

The Level control is used to adjust the input sensitivity
of the power amplifi er to the output voltage of your car
sound system preamplifi er output.
The adjustment range is from 0.3 V to 8 V.
If a car sound system of a third party manufacturer is
connected, the input sensitivity must be adjusted cor-
responding to the manufacturer data.
A few important explanations in this context:
By turning the control clockwise, the input sensitivity of
the amplifi er and, therefore, also the volume increases.
However, this is not a volume control; no further ampli-
fi er output can be achieved in the end position, even if it
may sound like that at the beginning. The system merely
increases the volume faster if the volume control of the
car sound system is turned up.
Loudspeaker connections
(If the amplifi er is to be jumpered, continue with the sec-
tion "Bridged loudspeaker connections" at this point).
As with every audio component, the correct polari-
sation of amplifi er and loudspeakers is of essentially
.

importance for a good bass response. For this reason,
ensure that the positive (+) connection of the amplifi er
is connected with the positive connection (+) of the
loudspeaker; the same applies to the negative (-) con-
nections. In addition, the left amplifi er channel must
be connected with the left loudspeaker and the right
amplifi er channel with the right loudspeaker.
Bridged loudspeaker connections
The EMA amplifi er can also be bridged for a mono
confi guration. This allows the amplifi er to be used for
one or several subwoofers or mid-range drivers. In this
confi guration, the amplifi er combines the right and left
channel to a single-channel output (mono output).
