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.
