The SPL HPm 500-Series Headphone Amplifier brings the power of a Phonitor Headphone Amp to the convenient format of the 500 series module!

The SPL HPm 500-Series Headphone Amplifier brings the Phonitor Matrix into the world of 500 series rack modules. Each of the two headphone outputs is fed with a separate amplifier to allow independent operation of two headphones with high-quality amplification. With the Phonitor Matrix you control Crossfeed, Speaker Angle and Center Level to create speaker-like listenig and monitoring on headphones. The HPm can easily be inserted between the DAW and a monitor controller because the input signals of the HPm are slaved through to the outputs of the 500 series rack. Phase Inversion of left or right channel as well as a Stereo/Mono/Mute switch round off the feature set of the HPm.

    Headphone Amp 500 series

    It is well built headphone amp for 500 series rack. The beauty of it is: it's like the insert between your audio interface ( or summing mixer) and main monitors (or monitor controller). So, if you don't use it, you could power off your 500 rack, and the audio still goes to monitors. Great for small studio, for one/two performers. As of the Matrix, it works, but I need to get used to it. My tests on friends (who are not musicians), showed, they like more regular sound with Matrix off. I understand that, as many of us used to listen music on regular headphones. Yet, the matrix works, if someone is curious, but it's not like mixing on real speakers. The other things; I use headphones outputs for small computer style speakers, which great to hear how mix sounds in reality. Always use 1/4'' TRS jack or TRS 1/8" adapter . Mono jack might damage the headphone as SPL says in the manual.
