DBX 120A Stereo Subharmonic Bass Synthesizer
DBX 120A Stereo Subharmonic Bass Synthesizer
The dbx 120A Subharmonic Synthesizer with Modeled Waveform Synthesis has been specially optimized by dbx engineers for the needs of audio professionals. Its two separate bands of bass synthesis provide the best combination of smoothness and control, and the independent Low Frequency Boost circuit is designed to get the most out of high-performance low frequency speaker systems.
Features:
- Individual control for two ranges of subharmonic frequencies
- Separate Low Frequency Boost Circuit
- Separate Subwoofer Output
- 1/4″ Balanced inputs and outputs
- RCA Input Connectors
- Front panel LEDs that show crossover status and synthesis activity
- Patented circuitry ensures that mid and high frequencies are not affected
- Built-in crossover with choice of 80Hz or 120Hz crossover point
- Enhance bass audio material for use in a variety of professional applications such as:
- Nightclub and dance mixing
- DJ Mixing
- Theater and Film Sound
- Music Recording
- Live Music Performance
- Broadcasting
