USB/SDPre amplifierModel:ABS-120U/180U/280U/380U/500U/650U

Features

1Standard 2U chassis, luxurious aluminum alloy panel, hand drawn design, beautiful and generous

23 microphone inputs); 2-channel line input (AUX1, 2); Each channel can adjust the volume, and one line auxiliary output can be connected to an amplifier to expand power

3The microphone MIC1 has a mute function, making it easy to insert for priority broadcasting;

4Equipped with independent adjustment for high frequency (TREBLE) and low frequency (BASS).

5Equipped with short circuit, overheating, overload protection circuits, and sound and light alarms;

62 power output modes, constant voltage output 100V, 70V, constant resistance output 4-16Ω

7Built in MP3/SD card interface decoder, compatible with MP3/WAV music playback formats.

Adopting advanced and efficient power amplification circuit, equipped with 3 microphone inputs, 2 line inputs, and 1 auxiliary output,InsertableUplate/SDPlay directly on the card, no need to purchase or burn music CDs, ready to use anytimeUplate/SDPlaying or changing songs with a card is more convenient and economical.The voltage output is 70V/100V, the fixed resistance output is 4-16 Ω, and the output frequency response range is 20-20KHz; Each input volume can be independently controlled, with high and low frequency volume adjustment; Microphone 1 is set as the highest priority function, automatically suppressing other input signals; The equipment is equipped with an abnormal operation protection warning function. When the input signal is too large, the load is too heavy, the temperature is too high, the line is short circuited, and other machine abnormal operation protection warning functions are activated, the corresponding indicator lights will prompt, and the fault will be automatically restored when it is eliminated, with high reliability. 2U standard chassis design, luxurious aluminum alloy panel, beautiful and generous. Solid power, stable and durable.

Scope of use: In situations where a combined constant voltage amplifier (power amplifier) is required, such as schools, shopping malls, specialty stores, restaurants, etc.

We can customize 240V output and provide OEM branded products according to customer requirements (there are also multiple models available)USB partition independent tuning amplifierandElectric Education Platform AmplifierAlternative)!
