This is an opportunity to own a great looking and perfectly working Aphex 520B Aural Exciter plug-in module that works with the TOA 900, Raymer 9000, and Peavey MA series amplifiers. The processor providesmany benefits including greatly improved presence and intelligibility without altering any other part of the audio system. The "Aural Exciter" is a dynamic process that recreates missing harmonic material lost to general degradation of the audio signal as it passes through any audiosystem and adds it back in the form of a very small cue signal. Because the enhancement signal is so small, it adds little power to the audio signal. The module installs in a single module space on the rear of the amplifier and takes its power from the amplifier. Bass boost for 0, +6 or +12dB of boost is jumper selectable.  It increases intelligibility, presence, and clarity and provides greater perceived loudness, adds perceived high end to dull or previously low pass filtered material, and is suitable for use in P.A. systems, paging systems, background and foreground music systems and stage monitors.  It automatically mutes for priority input.  

    Please email me with any questions.  I used a high resolution camera to give you accurate pictures of its condition.  I have years of  experience packaging delicate electronics, so rest assured, this will be packaged very well.  I also use high quality packaging materials.  Also, please check out the other items in my store.  Thank you for looking and God bless!
