The original Jam 150 was a huge success with its hugely musical tonality, superb frequency response and multi-channel operation. Input from users all over the world lead to the introduction of the Plus model which gave increased flexibility and performance and the latest update to the Plus model is phantom power; essential for condenser microphones and certain pickup systems.

The 150 features 150w RMS of Bi-amplified output and a selection of XLR, Jack and Phono inputs to allow for every conceivable input requirement. A line output is also included to allow the addition of an active extension cabinet or connection to other sound systems or recording equipment if required. The 150's unique ability to successfully handle a diverse range of music signals means that the 150 Plus can be found in homes, studios and music venues throughout the world. For the musician who appreciates pure sound quality there is no better compact combo in its class than the Jam 150 Plus.
