Ensure all connections are secure before powering on. The power switch is located on the amplifier panel. Power on your audio source and mixer before the AT212-MK3, and power off the AT212-MK3 before your audio source and mixer to prevent transient noises.
4.2 Input Level Adjustment
Adjust the Input Level knob on the amplifier panel to achieve the desired volume. Monitor the Signal and Limiting LEDs to ensure proper gain staging and prevent clipping. The multi-stage limiters protect the drivers from excessive peaks and thermal overload.
4.3 DSP Presets
The AT212-MK3 features eight on-board DSP presets, selectable via the Preset Select button on the amplifier panel. These presets offer different configurations, including a full-range mode (response down to 45Hz) and various satellite modes optimized for use with BASSBOSS subwoofers. Refer to the "Control BASSBOSS" software for detailed descriptions of each preset and additional computer-accessible options.
4.4 Rotatable Horn
The 80 x 60-degree horn can be rotated to optimize coverage for different applications, such as ground stack, horizontal, or vertical flying. Consult a qualified technician for horn rotation procedures.
5. Maintenance
