    Rolls HA204P reviews

    HA204p Portable 4-Channel Battery Operated Studio Reference Headphone Amplifier is rated 5.0 out of 5 by 1.
    Rated 5 out of 5 by from Rolls Amplifier Works as Hoped For I bought the Rolls Headphone Amplifier to allow several people to simultaneously monitor an audio feed and it has worked well. A power-cube is included for use when a power outlet is available, however I am using it in the Field so the 9v battery which can power it allows me to use the Rolls Amplifier anywhere. I am pleased with the rugged metal construction and the simple power switch and individual level controls, the Rolls sounds wonderful and I have tested it with several different portable Recorders and Headphones and I am quite pleased and would certainly purchase it again and can recommend it wholeheartedly.
