The SA-MA4C delivers 200 watts of clean power for solo performers, small bands, and presenters who need professional mixing and amplification in one compact unit. This 4-channel powered mixer handles microphones, instruments, and background music through multiple connection options including Bluetooth, USB, and SD card playback.

Built around a Class AB amplifier with integrated cooling, the SA-MA4C provides 100 watts RMS at 8 ohms or 200 watts RMS at 4 ohms to drive passive PA speakers. The onboard digital reverb effect adds 140-342ms of adjustable delay time, while individual channel controls for volume, bass, treble, and effects let you dial in each source independently.

Each of the four channels accepts both XLR and 1/4" TRS inputs, making it compatible with dynamic microphones, instruments, and line-level sources. The frequency response spans 20Hz to 20kHz with less than 1% total harmonic distortion, ensuring vocals and instruments come through clearly. A 3-band master EQ provides additional tonal shaping for the main output.

This mixer works well for coffee shop performances, small club gigs, church services, and outdoor events serving up to 150 people when paired with appropriate speakers. The built-in Bluetooth connectivity eliminates the need for additional music playback devices, while RCA tape inputs and outputs provide recording and playback flexibility.

Connect passive speakers to the dual 1/4" speaker outputs, and you're ready to perform. The rugged steel chassis protects the internal components during transport and setup. Seismic Audio backs the SA-MA4C with a full warranty and ships orders quickly from multiple warehouses nationwide.

Frequently Asked Questions

What size venue can the SA-MA4C handle?

The SA-MA4C works well for intimate venues up to 150 people when paired with efficient passive speakers. This includes coffee shops, small clubs, church fellowship halls, and outdoor acoustic performances. For larger venues or higher volume requirements, consider stepping up to a higher-wattage powered mixer or adding a subwoofer to extend the low-end response.

What cables do I need to connect speakers and microphones?

You'll need speaker cables with 1/4" plugs to connect passive speakers to the mixer's speaker outputs. For microphones, use standard XLR cables, and for instruments like guitars or keyboards, use 1/4" instrument cables. The mixer includes RCA inputs for connecting CD players or other audio sources, but those cables are typically sold separately.

Can I record my performance with this mixer?

Yes, the SA-MA4C includes RCA line outputs that send the main mix signal to recording devices, audio interfaces, or powered speakers. You can also use the RCA inputs to play back recorded tracks during your performance. The mixer handles both input and output simultaneously, making it useful for live recording or playback scenarios.

How does the built-in reverb effect work?

The digital reverb effect provides adjustable delay time from 140 to 342 milliseconds, which you can control globally and then adjust the send level individually for each channel. This means you can add more reverb to vocals while keeping instruments dry, or create different ambient effects for different sources. The effect works on all four input channels simultaneously.

Do I need additional equipment to play music from my phone?

No additional equipment is needed for wireless music playback thanks to the built-in Bluetooth connectivity. You can also connect devices directly using the USB port, SD card slot, or RCA inputs. The mixer includes a separate volume control for the music playback sources, allowing you to balance background music with live microphones and instruments independently.
