UE’s Pro Line Drive is a small, battery-powered stereo buffer that “conditions” the audio signal to drive your headphones, in-ear monitors or ear buds. It is connected between the mixing console, or personal monitoring system, or phone and your in-ear monitors, ear buds or any brand of headphones. The UE Pro Line Drive runs on two internal, 3-volt Lithium batteries (included and also with two spares) and has an on-off switch and two LEDs to indicate power on/off and the battery’s condition.
The UE Pro Line Drive is able to drive headphone impedances as low as two ohms to full level, without distortion from 10Hz to 50kHz. The unit “mirrors” whatever volume level you are sending to its Input jack at its Output jack. The big difference is that now the full sound quality mix, bass/treble and life of your music is maintained and accurately reproduced on any set of headphones.
The UE Pro Line Drive is a must for consistent sound quality and level when connecting your in-ears or favorite headphones to unknown headphone or in-ear monitor systems. It sells for $149 MSRP.
