Overview

With more and more studios foregoing consoles in favor of recording and mixing in the computer, a clean and versatile front-end input stage is indispensible. There are dozens and dozens of channel strips and similar devices to choose from, but none that come close to the Channel by way of sound, features or performance.

The legendary Model 230 has been re-imagined, adding a host of new features to address a greater number of workflows while retaining the sound, functionality and versatility that made it one of the most in-demand processors ever for professional audio, live sound, broadcast and post production.

The Channel incorporates seven powerful devices within a compact, single rack space design, including five of Aphex's exclusive patented technologies. Together, the result is the highest possible audio quality, processing power and flexibility available.

The elegant front panel not only looks great, but is laid out in an intuitive, easy-to-use workflow with easy to understand labeling. Building on the foundation of the Model 230, the Channel features an instrument input, dedicated output and gain reduction metering, front panel sample rate and clock source selection, and a reference quality internal clock.

Applications:

Broadcast
The Aphex Channel is a Tube Microphone Preamp and signal processor that is an indispensable broadcast station tool. You'll find them in the production room and installed as a permanent on-air processing for pumping up voices.

Comments about Aphex Channel Master Preamp and Input Processor:

This little guy it's so powerful. You have compressor, gate, de-esser, aural exciter and preamp all in one. I use it for music recording and, even when it's design for broadcast, sounds great (i have used it with vocals, guitars and percussion). The only thing that is not the best is the easy rider compressor , off course it?s great feature and usually works great, but if you want a high input with a little of compression, it's impossible (with more gain you get more compression, and even if you have a slow release you can feel it). So you can't have the exactly compression that you want. I'd discovered that if you use a not too much high gain (a little less than half) and a quarter of the release, you get a nice compression and a clear voice (also works with instruments).
