Aphex Exciter overview

  • 1Description

The Two-Channel Aphex Aural Exciter and Optical Big Bottom Effects Processor is a 1U 19" rack mountable post-processing effect designed to enhance details in your mix and add deep powerful low-end without unnecessary EQ boosting.

The device can be used in a wide variety of applications such as mixing in a recording studio, enhancing elements for live sound, adding clarity and intelligibility to installed sound setups, adding excitement to a DJ mix or karaoke session, and improving detail in audio for webcasting and Internet broadcasting.

The Aural Exciter processing circuit restores and recreates harmonics in the signal to enhance the differences in voicing and sonic details of a mix. Restoring the harmonics improves the clarity, presence, and intelligibility of the music. The device uses a Transient Discriminate Harmonics Generator to restore the harmonics over a wide range of signal inputs and program material.

The Big Bottom processing circuit provides a more powerful bass sound with increased density and sustain without boosting the peak output. Unlike bass-boost EQs or subharmonic generators that can increase the overload distortion of the signal, the Big Bottom circuit contours the bass response between 50 and 200 Hz to improve the perception of low frequencies.

The front panel of the device features a power button, and process on and off buttons for channels 1 and 2. Both channels feature Drive, Freq-Hz selector (from 600 to 5,000 Hz), and Amount knob controls for the Aural Exciter circuit. Both channels 1 and 2 also feature Drive, Freq-Hz selector (from 50 to 200 Hz), and Amount knob controls for the Optical Big Bottom circuit.

The back panel of the device features 3-pin XLR female inputs and 1/4" inputs for channels 1 and 2. For outputs, channels 1 and 2 have both 3-pin XLR male and 1/4" output jacks. A switch allows you to change the operating level of channels 1 and channel 2 between +4 dBu and -10 dBV.

    Aphex Exciter reviews

    Two-Channel Aural Exciter and Optical Big Bottom Effects Processor is rated 5.0 out of 5 by 4.
    Rated 5 out of 5 by from Aphex Exciter gets exciting with Big Bottom The item arrived at my door, well packaged. Unboxing, I found a plain brown box inside the outer box. Opening the inner box, I found the Aphex unit wrapped in plastic and an AC cord lieing beside it. A slip of paper with the internet address where I could download a .pdf of the owner's manual was included. I installed the Aphex unit into my equipment rack and it powered up, nicely lit. Playing some music through it, I quickly found the sweet spot and sat back and enjoyed the sonic landscape I had created with its help. This is a solid unit and works well in my all made in USA rack. I recommend this highly to those seeking a nice additional umph to their mix. Thanks Aphex and B&H for helping me accomplish my aurally exciting goals.
