Rolls PA71 Plus overview

  • 1Description

The Rolls PA71 Plus Mixer Amplifier is a "micro" mono power amplifier which mixes a microphone input signal with a stereo (mixed to mono) line level signal. The combined signal is sent to spring loaded output terminals via a 5 watt (into 8 ohms) power amplifier. The unit is ideal for small room applications where a simple mix of a microphone with a cassette or CD player is needed.

The PA71 Plus features a 1/4" TRS line/powered output which can be used for connection to another amplifier, or a standard pair of headphones. For those using a condenser microphone, the unit features switchable 12VDC phantom power on an XLR input.

    Rolls PA71 Plus reviews

    PA71 Plus Mixer Amplifier is rated 3.5 out of 5 by 2.
    Rated 2 out of 5 by from Not so hot I have had lots of little problems with Rolls products: noise, hum, distortion. The included adapter is cheap, lacks proper capcitors for filtering the powers supply. This would be OK out in afield at a boy scouts camp to announce lunch, but not so hot for quality audio. My experience is that other manufacturers of small mixers have higher quality control.

    Rated 5 out of 5 by from Surprising power Bought this only as a backup when doing an upgrade on a small space's existing PA. Turns out their old amp was bad so I stuck this in as a temp fix. It sounds so ggod, and fills this small space so well, we are leaving it in as the primary amp!
