The Audiofrog D300P Signal Processing Mixer/Amplifier includes a host of signal processing features for mains processing, microphone processing, processing of auxiliary speakers and for nearly any application in which mixing a music source and microphone inputs is important.

The D300P includes a two-channel high fidelity full range Class-AB amplifier rated to deliver 300 watts per channel into 8 ohm loads and 450 watts per channel into 4 ohm loads.

Two 300 watt channels of high fidelity class AB amplification with available outputs and signal processing for a subwoofer and center (mono) speaker provide plenty of power for hi-fi systems

Full-featured signal processing is available through the front panel controls or through PC software via USB. Abbreviated control via iPhone or iPad is provided by the Audiofrog app available in the app store.

Available processing includes polarity, crossover, parametric equalization and compression for each of the speaker and preamplifier outputs. Input processing includes parametric EQ and key control for music inputs, parametric EQ, crossover, feedback elimination, polarity and compression for microphone inputs. A full effects channel includes echo, reverb and parametric equalization. Finally, a digital mixer is available in software to balance between music, microphone and effects channels.

Seven factory presents and six user presets are available for storage and recall from the front panel or through the iOS or PC apps.

Whether you’re looking for a powerful and convenient way to integrate a PA with playback of recorded content or a main processor and amplifier in a professional Karaoke system in a pub or at home, no other solution compares to the Audiofrog D300P.
