About the product
1. A high-performance portable mini size front-end signal amplifying switcher and sound quality processor,
2. Built-in high-performance power processor and signal amplifier
3. For circuit design, Texas Instruments(TI) NE5532 dual operation amplifying chip in top quality acts as the front-end amplifier.
4. NE5532P is tailored for the high-performance audio system, which features ultralow harmonic distortion, low noise, high gain bandwidth or other.
5. Dual FET input widens the dynamic range for NE5532, and sound signal amplification and bipolar operational amplifier.
6. NE5532 audio enhancement technology can correct and recover any signal loss and phase deviation of audio signal system for any reason, reproducing sound and indulging the audiences in the spot effects of enhanced high-low sound, somewhat ideal positioning, definition and brightness.
7. With the audio enhancement circuit, audio system will brighten sound, bring you closer to depth, slenderness and definition, fine treble, penetrating middle and strong and natural bass, placing the audiences on spot.
8. Sound signal amplifying switcher, mainly used to switch various multi-channel signal inputs, such as computer, cellphone, tablet, game console, TV set, TV box, MP3.
9. Additionally with output equipment of signal source or other signal inputs, used for amplifying switch
10. The front-end output adopts 3.5mm interface, the back-end output adopts RCA interface. 11. 11. Simultaneous output of balance circuit architecture is enabled in front-end and back-end, output can be connected to the headphone, stereo, amplifier or any other equipment, used as sound signal amplifying switcher for four-channel signal input and two-channel signal output.
12. With a wide range of application, readily used in any signal input equipment, or used as the front-end signal amplifier, power supply adopts bleeding technology, uses the high-precision potentiometer for balance adjusting, and the positive and negative voltage balance is ultrahigh.
13. Additionally with the tailored high-capacity filter capacitor, ensuring the clean power supply.

Main Features
1. Four-channel switch circuit (3.5 headphone base and gilt RCA base) replaces input signal with no need to unplug, just turn the panel option switch.
2. High-precision power bleeder circuit ensures the stability of circuit and reduces DC shift of output.
3. Advanced input and output connecting base ensures the smoothness and durability of signal channel.
4. NE5532, well-tailored for the high-performance audio system in best signal amplification, acts as front-end amplification.
5. Original potentiometer made in Taiwan, with small sound loss, high balance, good hand feel and durability.
6. Aluminum alloy housing has a high density of wiredrawing in oxidation treatment, good-looking and noble with screen, but with no color-shading as paint spraying.
7. Standard input interface: 4 x 3.5mm (with four-channel signal input switch)
8. Standard output interface: 3.5mm headphone base and RCA red-white audio base (with simultaneous output)
