What Analog Channel HD v7 is for
Analog Channel HD v7 is a plug-in designed to bring a credible analog signature to your sessions, whether in mixing or mastering. It allows you to add density, cohesion, and a "glue" feeling on individual tracks (vocals, drums, bass, guitars, synths) as well as on buses (drum bus, mix bus). Thanks to its two configurations, you can choose either a "console channel" approach with the AC101 or a more pronounced "tape" approach with the AC202, to recover rounder transients, progressive saturation, and a more organic character.
Main features
AC101: analog channel emulation (preamp / amp) in mono and stereo
The AC101 module focuses on emulating an adjustable analog amplifier, designed to enrich the signal without altering it. On a vocal, it can bring presence and slight harmonic thickening; on a bass or kick, it helps reinforce the sense of foundation; on synths, it adds depth and a less "clinical" sound. Availability in mono and stereo allows integration on both individual tracks and buses, maintaining a stable image.
AC202: tape and tape machine emulation with machine parameters
The AC202 module aims for a more complete reproduction of tape system behavior, with typical tape machine controls such as bias, tape speed, and selection of IEC1/2 standards. This approach is ideal for shaping dynamics musically: softening overly aggressive attacks, thickening low-mids, smoothing the high end, or giving a more "vintage" feel to digital recordings. The AC202 is also designed to cover professional speeds and different tape formulations, to achieve various degrees of natural saturation and compression, from subtle to more colored.
Playback heads, digital precision, and workflow
Analog Channel HD v7 includes a playback head emulation based on specifications and measurements from recognized reproduction system manufacturers, to recover typical playback behavior (tonal contour, sense of depth, interaction with tape). The plug-in uses double-precision processing (double-precision arithmetic) to preserve quality during cumulative processing, and remains suitable for dense projects thanks to its ultra low latency.

Questions frequently asked
Is McDSP Analog Channel HD compatible with macOS Sonoma and Windows 10?
The announced compatibility covers macOS 10.13 High Sierra through macOS 14 Sonoma, as well as Windows 10. macOS 10.12 Sierra may work without official support.
What is the difference between the AC101 and AC202 modules?
The AC101 models a mono or stereo analog channel to enrich the signal. The AC202 emulates a tape system with bias, tape speed, and IEC1/2 standard settings.
Can the tape emulation be used on a drum bus?
The AC202 processing softens transients and thickens low-mids, actions suited for a drum bus. Both modern and vintage tape formulas and professional tape speeds allow controlled saturation.
Does the plug-in add latency?
The processing is reported to have ultra-low latency, which favors its use in dense projects.
What is the benefit of double-precision processing?
Double-precision computation preserves sound quality during cumulative processing. The tape head emulation is based on specifications and measurements from reproduction system manufacturers.
