Car radio DSP/FM/USB/SD/Bluetooth
ADX-903BM DSP
DSP/FM/USB/SD/Bluetooth car receiver, multi-color backlight
Receiver with high-performance original ACV Soundstone DSP-SS1 sound processor and 3 pairs of 4 volt RCA audio outputs. Equipped with a built-in amplifier with a maximum power of 4x50 watts. FLAC 24bit 96kHz support.
ACV SOUNDSTONE DSP-SS1
The player stands out thanks to its own design and high-performance DSP called ACV Soundstone DSP-SS1. This gives you incredible audio control right in the player and support for high resolution FLAC 96kHz 24bit audio files. You can use 2-band mode with a high-pass filter in front and rear, or 3-band mode with selected crossover frequencies, the filter cutoff order can be selected between 6/12/18/24 dB per octave.
4 VOLTS ON 3 PAIRS OF RCA AUDIO OUTPUTS
When designing a car speaker system, it should be taken into account that the higher the output voltage at the preamplifier output, the higher the noise immunity and the cleaner the sound at the output.
BLUETOOTH 5.0
Built-in module for Hands-Free, music listening and control via ACV DSP Control App. Bluetooth technology ensures safety and comfort while driving.
- the effect of being in a concert hall or on the dance floor;
- Feeling the live sound of instruments;
- Listening comfort at any volume.
