Loudspeaker connections, Integral fuses

GTA 250

Positive/negative connection

We recommend a cable cross-section of not less than 6 mm2. Run a standard commer- cial positive cable to the battery and con- nect to the fuse holder. Use cable grommets when passing cables through holes with sharp edges. Bolt a standard commercial negative cable to a ground point free of in- duced noise (car body bolt, body panel) - not to the negative battery pole. Clean the contact surface of the ground point down to bare metal and coat with antiseize graphite petroleum.

Integral fuses

The integral fuses within the amplifier pro- tect the final stage and the entire electrical system in the event of a fault. Never bridge fuses or replace fuses with a higher current rating.

+12V

Connect remote amplifier connec- tion to switchable +12 V power source.

This enables the amplifier to be switched on and off with the radioÕs On/Off switch.

Level control

The Level control enables the input sensi- tivity of the final stage to be matched to the output voltage of your car radio preamp out- put.

The range of adjustment extends from 0.1 V to 8 V.

Adjust the input sensitivity in accordance with the manufacturerÕs specifications when con- necting the amplifier to other radios.

Important:

Turning the Level control clockwise increas- es the input sensitivity of the amplifier, and thereby also the volume. The Level control is however not a volume control; an increase in volume is not achieved in the maximum position, even if this subjectively appears to be the case. The system merely increases the volume more quickly when the volume is turned up on the radio.

Loudspeaker connections

(If the amplifier is to be connected in a bridged mode, proceed with the section ÒBridged loudspeaker connectionsÓ.)

As with any audio component, connection of the amplifier and speakers with the cor- rect polarity is essential for good bass re- production. Ensure therefore when connect- ing that the positive (+) amplifier terminal is connected to the positive (+) loudspeaker terminal. The same applies to the negative (-) terminals.

GTA 250 specifications

The Blaupunkt GTA 250 is a remarkable power amplifier that caters to audio enthusiasts seeking to elevate their sound experience with powerful performance and exceptional sound quality. Known for its compact design and robust features, the GTA 250 is designed to seamlessly fit into various automotive audio systems, delivering an impressive blend of power and clarity.

One of the standout features of the Blaupunkt GTA 250 is its impressive power output. With a maximum power of 250 watts, this amplifier guarantees that users can enjoy high-volume levels without distortion. The combination of high-efficiency design and low heat generation makes it a reliable option for extended listening sessions. It operates in a Class AB configuration, ensuring that the audio remains natural and vibrant, regardless of the volume levels.

The GTA 250 is equipped with advanced technologies that enhance audio performance. It includes a built-in low-pass filter that allows users to tailor the frequency response to their liking. This feature is particularly beneficial for those who want to integrate subwoofers into their system, as it provides precise control over the bass frequencies. The amplifier also boasts a high-pass filter, which can be used to ensure that higher frequencies are transmitted cleanly, effectively minimizing distortion and resulting in a well-balanced sound.

Another noteworthy characteristic of the GTA 250 is its robust construction. The amplifier features a sturdy aluminum chassis that not only contributes to its durability but also aids in the cooling process. Efficient heat dissipation is crucial for maintaining optimal performance, especially during heavy usage.

The amplifier supports both RCA and speaker-level inputs, making it versatile for various installation scenarios. This flexibility allows users to connect it to a wide range of audio sources, ensuring compatibility with both factory and aftermarket head units.

Overall, the Blaupunkt GTA 250 is an excellent choice for those looking to enhance their car audio system. With a combination of powerful performance, advanced technologies, and solid build quality, it stands out in the competitive market of automotive amplifiers. Whether you are a casual listener or an audio aficionado, the GTA 250 promises to deliver an engaging sound experience that transforms the way you enjoy music on the road.
