If a replacement fuse is used, never bridge fuses or replace

them with a type with higher current.

+12V

Remote connection of the ampli er with switchable +12 V

voltage source.

This allows the ampli er to be switched on and o using the

on/o -switch of the radio device.

Level control

The Level control is used to adjust the input sensitivity of

the power ampli er to the output voltage of your car sound

system preampli er output.

The adjustment range is from 0.3 V to 8 V.

If a car sound system of a third party manufacturer is con-

nected, the input sensitivity must be adjusted corresponding

to the manufacturer data.

A few important explanations in this context:

By turning the control clockwise, the input sensitivity of the

ampli er and, therefore, also the volume increases. However,

this is not a volume control; no further ampli 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 ampli er is to be jumpered, continue with the section

"Bridged loudspeaker connections" at this point).

As with every audio component, the correct polarisation of

ampli er and loudspeakers is of essentially importance for a

good bass response. For this reason, ensure that the positive

(+) connection of the ampli er is connected with the posi-

tive connection (+) of the loudspeaker; the same applies to

the negative (-) connections. In addition, the left ampli er

channel must be connected with the left loudspeaker and

the right ampli er channel with the right loudspeaker.

Bridged loudspeaker connections

The GTA ampli er can also be bridged for a mono con gura-

tion. This allows the ampli er to be used for one or several

subwoofers or mid-range drivers. In this con guration, the

ampli er combines the right and left channel to a single-

channel output (mono output).

Note:

The ampli er can add the right and left signal information

only if the right as well as the left RCA connection were

carried out.

Caution:

In a bridge circuit, the ampli er load must be 4 ohm or

higher. A lower load leads to an overheating or switch-o

of the ampli er and can cause permanent damages.

Adjusting the type and range of the

frequency crossovers

With the GTA 4 Special, the type of frequency crossover (i.e.

"Low Pass" or "Hi-Pass") and the desired entry frequency can

be adjusted. For example, if a pair of subwoofers is to be

connected, the low-pass settings shown are required (Fig. 3).

The entry frequency is dependent upon the frequency range

of the loudspeakers (see recommended frequency range of

the loudspeakers).

High-Pass

At a setting of 80 Hz, the ampli er has a frequency range of

80 Hz to 25,000 Hz.

Low-pass frequency control

This control is active if the switch is in the position "Low-Pass",

and allows for setting the desired entry frequency.

Example:

At a setting of 150 Hz, the ampli er has a frequency range

of 10 Hz to 150 Hz.

Bass boost

The bass boost control is used to adjust the bass response

of the ampli er.

The setting options are: 0 dB / +6 dB / +12 dB.

Power-on indicator (POWER / PROTECTION)

Green LED:

Output stage on, regular operating status.

Red LED:

Output stage is electronically switched o due to an error.
