## Summary description

4-channel audio mixer DNA CM4-DSP with built-in DSP, USB connectivity, MP3 playback and Bluetooth. Designed for live sound, small PA systems, streaming and content creation, it supports multiple inputs across four channels and on-board digital processing for EQ and effects, plus USB audio interface and MP3/Bluetooth source playback.

## Long description

The DNA CM4-DSP USB MP3 Bluetooth is a compact 4-channel audio mixer with integrated digital signal processing, USB connectivity and onboard MP3/Bluetooth source playback. Designed for small PA systems, live sound reinforcement, podcasting and streaming, this mixer combines multiple analogue inputs with a built-in DSP for basic equalization and effects. The unit also functions as a USB audio interface for direct connection to a computer and supports playback from USB memory and Bluetooth devices.
Advantages
The mixer offers four input channels with individual level control and routing, plus a set of DSP functions for tone shaping and basic effects. USB connectivity enables two-way audio transfer to a computer for recording or streaming, while the MP3 and Bluetooth playback features provide convenient source options without external players. The compact footprint and simple control layout make the unit suitable for setups where space and straightforward operation are important.
Suitable for
 Small live performances and rehearsal rooms
 House-of-worship and small venue public address systems
 Podcasting, streaming and home studio recording
 Background music playback in retail or hospitality via MP3 or Bluetooth
When it may not be suitable
This mixer is intended for small- to medium-scale applications and does not replace a full-size mixing console required for large events with extensive channel counts or advanced routing needs. It provides basic DSP functions appropriate for general tone control and simple effects but is not a substitute for high-end external processors or multi-band professional mastering tools.
Key specifications
 Number of channels: 4 analogue input channels
 DSP: onboard digital signal processing for EQ and basic effects
 Connectivity: USB audio interface for computer connection; Bluetooth wireless playback; USB memory MP3 playback
 Outputs: main outputs and monitor outputs (balanced/unbalanced depending on wiring)
 Power: external or internal power supply as supplied with the product (follow manufacturer guidance)
 Form factor: compact desktop mixer suitable for tabletop placement
How to use
Connect microphones and line-level sources to the available input channels and adjust gain and channel level controls for the desired mix. Use the DSP controls to apply EQ and effects as needed for the room and source characteristics. For recording or streaming, connect the mixer to a computer via the USB port and select the device in your recording software. To play back music directly, insert a USB memory device with MP3 files or pair a Bluetooth-enabled device and select the source on the mixer. Route the main mix to loudspeakers or an amplifier using the main outputs and monitor the signal through headphones if available.
What to consider before purchase
 Confirm the number and type of inputs you need (microphone vs line-level) for your setup
 Check that the available outputs match your speaker or amplifier input types
 Ensure compatibility with your computer and recording software for USB audio interface use
 Consider whether the onboard DSP features meet your requirements for EQ and effects
Usage recommendations
For reliable operation, use balanced cables for long runs, set input gains conservatively to avoid clipping, and test the DSP settings in the actual room environment. When using USB audio, install any recommended drivers and verify sample rate settings in your DAW or streaming software to prevent latency or sync issues.
