Marantz PHA3

Portable 3-way headphone preamplifier

The Marantz PHA3 portable headphone preamplifier supplies three independent headphones from balanced or unbalanced sources and produces high levels at audiophile level with lowest distortion.

Ready for use anywhere

By means of 2x AA alkaline batteries it can be operated completely independent of the mains. This makes the PHA3 ideal for broadcast productions, film crews and live applications where high level monitoring is required. For each channel, a peak LED reliably indicates any distortion of the signal. An additional loop output allows the cascading of several PHA3 preamplifiers.
