4. Balanced Inputs: The SF-MA100A offers balanced XLR inputs, which can help reduce noise and improve signal integrity.
Cons:1. Limited Input Channels: This amplifier only has two channels, which might not be enough for more complex sound systems that require multiple input sources.
2. No Bluetooth Connectivity: The SF-MA100A does not have Bluetooth connectivity, so you'll need to use wired connections to input audio sources.
3. No Built-In EQ: The mixer-amplifier does not have an equalizer built-in, so you may need to use external EQs or processors to fine-tune your sound.
In conclusion, the RDL SF-MA100A is a powerful and versatile amplifier suitable for large-scale sound systems. However, it may not be the best choice for more complex setups requiring multiple input sources or built-in EQs. If you're looking for a simple and cost-effective solution for a 70V or 100V line-array system, the SF-MA100A could be a good option. However, if you need more channels, built-in EQ, or Bluetooth connectivity, you may want to explore other options.
Recommendation: If you're looking for a 100W mono mixer-amplifier for a 70V or 100V line-array system and don't require advanced features like multiple input channels or built-in EQ, the RDL SF-MA100A could be a cost-effective and reliable choice for your needs.
Details:
The unit is engineered for continuous duty in demanding installations and includes a 48 CDC module power supply. Installer-adjustable rear-panel pots set input gain and the vac range for remote control, simplifying commissioning maintenance. The compressor features automatic attack and release timing for transparent dynamic control. The SF-MA100A is a 100 watt constant- voltage mono mixer-amplifier that accepts three format-a audio inputs and provides 70 v or output.
Performance specifications provide useful headroom and clean output: 100 w RMS constant- voltage output, frequency response of 0/-3 db from 50 Hz to 20 khz, Thad n under 1% at full power, noise floor below -85 maximum power. Key features include three delectable operating modes, internal vacs for noise-free level control, a audio compressor that adds up to 15 db of headroom, and dual-led VI meter installer metering. The amplifier uses a high-efficiency class output stage to minimize heat and improve reliability. It mixes multiple sources and can be controlled locally or remotely to fit different operational workflows.
It mixes the three format-a pairs locally or via remote vac control and passes signal power through to a loop-out jack.
