1U Integrated MP3 Amplifier
6.Equipped with 1 USB port on the front panel, supporting lossless playback of APE, FLAC, WMA, WAV and MP3 audio formats; it is also provided with physical keys for
previous/next track, play/pause, equalizer and mode selection.
7.Built-in FM radio supports automatic station search and station storage.
8.Adopts LCD liquid crystal display and touch-sensitive function keys for operation.
9.Comes with an infrared remote controller to control all player functions.
10.6-channel signal input (4 microphone inputs, 2 line inputs, 1 EMC input).
11.4 microphone channels adopt balanced signal input, with built-in DC 48V phantom power (switchable on/off).
12.1 auxiliary signal output for cascading connection with the next amplifier.
13.Equipped with 70V, 100V constant voltage output and 4-16Ω constant resistance output.
14.Supports master volume adjustment, independent volume adjustment for each input channel, and independent treble & bass adjustment.
15.The volume potentiometer adopts fully sealed dustproof technology, permanent dustproof design with noise-free adjustment.
16.EMC has the highest priority: AUX1/2 and MIC1/2/3/4 signal attenuation ranges from 0 to -30dB.
17.MIC1 has the second priority: AUX1/2 and MIC2/3/4 signal attenuation ranges from 0 to -30dB.
18.Integrated comprehensive protection functions including output short-circuit protection, DC protection, overload protection and over-temperature protection.
19.Wide voltage power supply design: AC 100~240V, 50/60Hz.
