Recommendation

The performance of an amplier can only be as good as its installation. Correct installation increases the overall per forma nce of your car sound system. The GTA amplier should be installed by a trained person. If you would like 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 highperformance systems and loudspeaker congurations 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! Observe the safety notes of the vehicle manufacturer.

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

- Please use minimum 10AWG power & ground cable with a fuse located within 18 inches of the battery.

- Use cable glands for holes with sharp edges.

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

Installation and connection instructions

With respect to accident safety, the GTA 260 must be secured in a professional way.

When selecting the installation location, select a dry location that oﬀers suﬃcient air circulation for cooling the amplier.

The GTA 260 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 accompanying screws and provide a rm support.

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

Use loudspeakers with 2 - 4 Ohms impedance (see table or installation drawing). Do not connect loudspeakers to ground, use only the referenced terminals.

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 interference.

The preamplier outputs are connected to the cinch (RCA) socketsj) via a shielded sound cable.

With control via the loudspeaker outputs, the input connections of pos. k/l are fed t o the clo sest loudspeaker cables (front or rear) on the left and right. They a re separated and connec ted t o the inp ut connections. The polarity of the +or - connections must be observed. Bridge output stages (BTL) can also be connected directly without an additional adapter.

Positive / negative connection

- We recommend a minimum cross section of 10 AWG

- Route commercially available positive cable to the battery and connect via fuse holder.

- Use cable glands for holes with sharp edges.

- Securely fasten commercially available negative cables to a noise-free ground point (chassis screw, chassis metal) not to the negative pole of the battery.

- Scrape the contact surfaces of the ground point until they are bright and grease with graphite grease.

Integrated fuses (Fuse)

The fuses integrated in the amplier (Fuse) protect the power ampli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.

Connection examples

Connection of the voltage supply............Fig. 2

Audio inputs....................................................Fig. 3

Loudspeaker connections..........................Fig. 4/5

+12V

Remote connection of the amplier with switchable +12V voltage source. This allows the ampli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 amplier to the output voltage of your car sound system preamplier output. The adjustment range is from 0.2 V to 10V. If a car sound system of a third party manufacturer is connected, the input sensitivity must be adjusted corresponding to the manufacturer data.

An 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 full 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.

DC Oﬀset- 4

When connecting to an OE radio, it may not be possible to connect the remote turn on lead on the amplier, please use the high level input available on the side panel & turn on DC Oﬀset to automatically turn on/oﬀ the amplier when the OE radio is turned on / oﬀ.

Loudspeaker connections

As with every audio component, the correct polarity of amplier and loudspeakers is important for a good bass response. For this reason, ensure that the positive (+) connection of the amplier is connected with the positive 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guration. In this conguration, the amplier combines the right and left channel to a single-channel output (mono output).

Caution:

In a bridge circuit, the amplier load must be 4 ohm or higher. A lower load leads to overheating & cause the amplier to switch oﬀ & can cause permanent damage.

Adjusting the type and range of the frequency crossovers

With the GTA 260, the type of frequency crossover (i.e. "Low Pass" or "Hi-Pass") and the desired frequency can be adjusted. For example, if a subwoofer is to be connected, the low-pass settings shown are required (Fig. 3). The frequency is dependent upon the frequency ra nge of th e lo udspea ke rs (s ee reco mm end ed frequency range of the loudspeakers).

High-Pass - 80Hz

At a setting of 80Hz, the amplier has a frequency range of 80Hz to 30,000Hz. (Ideal for Coaxial & Component Speakers).

Low-pass frequency control

This control is active if the switch is in the position "LowPass", and allows for setting the desired entry frequency.

Example: At a setting of 120Hz, the amplier has a fr eque ncy ra nge o f 1 0Hz t o 1 20H z. (I deal for Subwoofers).

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 (PWR / PRO)

Green LED: Output stage on, regular operating status. Red LED: Output stage is electronically switched oﬀ due

to an error.
