International orders*The Aphex Channel is a fully featured, single-channel microphone preamp and channel strip that offers high-quality sound and a wide variety of signal processing. The 1U unit is a re-imagined version of the company's 230 preamp, and is designed for professional studio, stage, and broadcast applications. It sports an array of I/O including XLR mic and 1/4" instrument inputs; XLR and 1/4" outputs; AES/EBU, S/PDIF, and TOSLink digital outputs; and Wordclock in and out. Balanced 1/4" insert send-and-return jacks allow for patching in external processors.
The preamp is Aphex's patented Reflected Plate Amplifier (RPA) type, designed to provide ultra-wide bandwidth and maximum gain and headroom. It features a transformerless design, and contains a second-stage 12AT7/ECC81 Dual Triode tube.
The Channel is also equipped with six built-in processors including several patented Aphex effects. You get the Aural Exciter, for dialing in additional presence and clarity to the signal; Big Bottom, which provides deeper and more resonant bass; the EasyRider Class A compressor, featuring automatic adjustment of attack and release parameters based on the characteristics of the input signal; and the Logic Assisted Gate, which helps eliminate false triggers, clicks, and chattering. In addition, there's a fully parametric EQ band for adjusting the midrange frequencies between Big Bottom and the Aural Exciter, and a de-esser.
