Deaf Bonce Gemini 770DSP – High-Performance DSP Car Stereo

Take complete control of your car audio system with the Deaf Bonce Gemini 770DSP, a high-performance 1-DIN car stereo with an integrated digital signal processor (DSP), high-voltage RCA outputs and built-in amplification.

Designed for serious car audio systems, the Gemini 770DSP combines a 4 × 25-watt RMS Class AB amplifier, 8 RCA preamp outputs, up to 5.5 volts of RCA output, Bluetooth connectivity, USB playback and advanced DSP tuning in one compact head unit.

Whether you're running speakers directly from the radio or building a multi-amplifier system for mids, highs and subwoofers, the Gemini 770DSP gives you significantly more control over your audio system than a basic aftermarket radio.

BUILT-IN DSP FOR SERIOUS SOUND TUNING

The biggest advantage of the Gemini 770DSP is its integrated DSP.

Instead of simply sending music to your amplifiers, the DSP allows the system to be tuned for the vehicle and speaker layout. The Gemini provides time-delay adjustment from 0–18 ms in precise 0.1 ms steps, helping align the arrival time of individual speakers to create a more focused soundstage.

Additional published Gemini 770DSP documentation describes a 28-band equalizer and crossover control up to 24 dB/octave, making this head unit especially useful for active and multi-amplifier car-audio systems.

8 RCA OUTPUTS WITH UP TO 5.5V

The Gemini 770DSP is built for customers running external amplifiers.

You get 8 RCA outputs total:

6 × wideband RCA outputs
2 × dedicated subwoofer RCA outputs

The RCA signal reaches up to 5.5 volts, giving compatible aftermarket amplifiers a strong preamp signal and plenty of system flexibility.

This makes the 770DSP a strong foundation for systems using separate amplifiers for midrange speakers, tweeters, midbass drivers and subwoofers.

4 × 25W RMS BUILT-IN AMPLIFIER

Don't need an external amplifier for every speaker?

The Gemini 770DSP includes a Class AB internal amplifier producing 4 × 25 watts RMS at 4 ohms.

That allows compatible speakers to be powered directly from the head unit while still providing the RCA outputs necessary to expand the system with additional amplifiers later.

BLUETOOTH 5.3 + HANDS-FREE CALLING

Published Gemini 770DSP specifications list Bluetooth 5.3 connectivity along with hands-free calling support.

Stream music wirelessly from a compatible smartphone while maintaining the advanced DSP and amplifier controls expected from a serious car-audio head unit.

USB + LOSSLESS AUDIO SUPPORT

The Gemini 770DSP includes a USB input and supports:

MP3 • WMA • AAC • FLAC • WAV

That includes popular lossless formats such as FLAC and WAV, making the radio suitable for customers who prioritize high-quality source material.

16.7 MILLION-COLOR ARGB ILLUMINATION

Customize the appearance of the radio to complement your vehicle interior or audio build.

The Gemini 770DSP features ARGB illumination with up to 16.7 million colors, giving the face of the stereo a customizable appearance instead of locking you into a single illumination color.
