Product description The silver Pro-Fi Series Phonitor e Headphone Amplifier from SPL offers connections for headphone operated both balanced and unbalanced. For the balanced operation it has an advanced dual power amp built-in which delivers twice the power of the standard 1/4" jack output. This tightens the bass response and makes the overall playback even more relaxed and transparent. The front houses a 4-pol XLR connector to connect the balanced headphone. Both the standard and the 4-pol headphone outputs can be used simultaneously. The Phonitor-Matrix offers two presets. The speaker angle is fixed to the most common setting of 30° representing the suitable angle for a stereo speaker placement. The VOLTAiR 120V Rail Technology is developed and manufactured to run on an operating voltage of 120V, which corresponds to twice that of discrete operational amplifiers and four-times that of semiconductor operational amplifiers. It reproduces finest details and delivers a totally relaxed sounding audio experience. The music sounds natural and hearing fatigue is reduced. - 120V Rail headphone amplifier

- Suited for all headphones with impedances >10 Ohms
- Balanced and unbalanced analog inputs (XLR and RCA)
