Additionally, the L70 includes four jacks to accommodate most headphones: 4-pin XLR balanced, 4.4mm balanced, 6.35mm single-ended, and 3.5mm single-ended.\u003c\/span\u003e\u003c\/p\u003e\n \u003ch2\u003e\u003cb\u003eUltimate compatibility\u003c\/b\u003e\u003c\/h2\u003e\n \u003cp\u003e\u003cspan style=\"font-weight: 400;\"\u003eTOPPING designed the L70 to be able to power the vast majority of headphones. With high output voltage, it easily drives high impedance headphones. With high output current, it easily drives low impedance headphones.

This simple jack lets you create a network between any units that also feature a 12V trigger. When connected, it makes one product control the power of the other products in the system.

Ground loop noise most often manifests as a buzzing or humming sound, which is capable of being loud enough to damage speakers. Although it's known to happen most often in single-ended feeds, it can happen in balanced feeds, too.\u003c\/span\u003e\u003c\/p\u003e\n \u003cp\u003eThe L70 solves this issue with a GND\/LIFT switch. When in normal use, set the switch to GND. If you encounter ground loop noise, set the switch to LIFT, which will change the ground point of the L70 from its chassis to the equipment it’s connected to, eliminating the noise.\u003c\/p\u003e\n \u003ch2\u003e\u003cb\u003eVolume memorization\u003c\/b\u003e\u003c\/h2\u003e\n \u003cp\u003e\u003cspan style=\"font-weight: 400;\"\u003eThe L70 can memorize the volume and gain settings for 8 separate outputs.
