L1 features its wide gain range, wide frequency response, excellent S\/R and HiFi sound, to bump the output level of the audio devices which are with an inherently low level output so as to match other sources, or to allow the use of a longer cable run than normal between components.\u003c\/div\u003e\n\u003chr\u003e\n\u003cdiv\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan\u003eMutiple input\/output interfaces: with 3.5mm AUX\/stereo RCA\/5-DIN inputs and stereo RCA\/5-DIN outputs, can be compatible with most low-volume audio sources such as ipod, ipad, phone, TV, MP3 player,  potable CD player, computer, video game etc., and boost their output to the level needed to drive amplifier or speakers.\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan\u003eWith built-in amplification and voltage boost circuit: adjustable gain to match better with different audio sources, support DC 5-24V wide input voltage that can share the power supply of amplifiers, while L1 can always work at a high voltage of 26V to provide ±12.5V high output amplitude and max 20dB high gain.\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan\u003eUnique design and HiFi clear sound: double-side PCB design, NE5532P op amp with pluggable socket design, convenient to change other op amps to enjoy different sound and bring much DIY fun for audiophiles.
