GTA 475 GTA | The Best Value Series 4ch Power Amplifier
A small feature that makes a big difference.
Many car radios nowadays still lack a separate Aux input for connecting an external signal source. And in the OE audio systems installed at the factory, this additional input is also still an absolute exception. Being so, the additional audio installation of a portable music player such as an iPod, a DVD player or a navigation system was virtually impossible in the past. Blaupunkt now offers a simple and effective solution to this problem: An amplifier equipped with a Direct Aux Input. The auxiliary source is now connected directly to the amplifier which not only enhances the music experience due to its ample power reserves but also serves as a mixer for the different audio signals. The great thing about the Direct Aux Input: There is no additional switching facility required! Simply hook up the signal source to the amp via the optional connection cable (001 525) thats it! How it works in practice: The amplifier is switched on by the car radio via the remote signal. Then turn down the volume completely on the car radio and control it directly on the external source. The big advantage: When receiving a traffic announcement, it is simply mixed into the music signal and put through directly.
The GTA 475 has one Direct Aux Input each for the front and rear channels. This would even allow to hear the navigation voice output loud and clear in the front seats while the kids in the back row enjoy their our own music program from the portable MP3 player.
Direct input for portable music and navigation
To play back a portable music player such as an iPod via all four channels, a Y adapter is optionally required (available under the P/N 001 524).
Things can be so easy: The headphones output of the portable navigation system is connected to the Direct Aux Input of the GTA 475 and the driving recommendations will be simply mixed into the music signal. The voice output volume is adjusted directly on the navigation system.
Everything under control the fully featured rear connector panel of the GTA 475. New: HighLevel inputs for direct hook-up to the radios speaker outputs (ideal if the radio has no preamp outputs).
