AT-2002S AT-2003S AT-2008S

Effect of professional digital analog front amplifier by d/a reverb processing, vocal effects more rich, natural, transparent. Is a high-fidelity smooth and natural sweet style of stereo pairs of reverberation and multi-purpose karaoke effects. With DSP numerical control, according to set a tone and the effect of regulation. Make the effect more exquisite and more can meet the needs of the different hearing. The built-in digital frequency shift function, make the singing more perfect. Output is before (after) around a track, in the vocal tract, ultra-low frequency channel. And use like karaoke borne power amplifier, is very convenient.
S use of high-grade aluminum alloy panel, 1.5 U standard fuselage design more show atmosphere, the card package way make debugging more relaxed and concise convenient adjustment.
S a microphone with music has six sections of equilibrium parameter adjustment, the adjusting range is wider, more exquisite and soft voice, do not damage the original tone at the same time, improve sound quality, and the effect of single band, deal effectively with the noise frequency points.
S ultra-low sound channel output design with adjustable frequency and output gain;
S ultra-low channel has perfect low-frequency self excitation circuit, when entering the MIC, low frequency signal output port automatically decay half in order to prevent the low frequency noise and damage to the equipment; With a microphone and not into the ultra-low channel function.
S design can choose the music/sound channel output of reverberation ratio or pure vocals dry sound; And can control the volume and high frequency regulating independently.
S DSP digital control display on the front panel, tones and adjustable reverberation, let more able to adapt to the needs of different hearing sound effects.
S a built-in digital frequency shift processor. Can effectively restrain the noise points, make it more perfect singing.
