Audient ASP8024 Heritage Edition 72 Ch Inline Console is a 72-channel fully analog in-line recording console with 24-bus routing — the largest standard configuration of the ASP8024-HE platform, comprising six 12-channel bays plus the master section, spanning 331 cm wide and weighing 234 kg. The 72-channel version requires two ASP8120 Ultra power supplies, both included. The preamp circuit, EQ topology, Retro Iron mix bus, and VCA bus compressor are identical across all Heritage Edition configurations; what the 72-channel format delivers is simultaneous access to every signal source in a large-scale session without patchbay reconfiguration — the natural territory of orchestral recording, large ensemble tracking, and permanent high-throughput studio installations.
In-Line at Scale — 160 Inputs From a Single Console
In the 72-channel configuration, the in-line architecture delivers 160 inputs to the stereo bus at mixdown: two independent signal paths per channel (long fader for mic/line, short fader for DAW or tape return) plus four stereo returns in the master section. The four-band Dearden EQ — two fully parametric mid bands spanning 40 Hz to 20 kHz with ±15 dB and variable Q, flanked by low and high shelving bands — is splittable independently per channel: it can be assigned to the mic/line path or the tape return path without affecting other channels. Fourteen aux sends (12 mono plus 2 cue) accessible on both fader paths per channel allow simultaneous management of studio headphone feeds, outboard effects, and stem routing across all 72 strips. Penny & Giles 8000 series faders are fitted on every channel.
Retro Iron, VCA Compression, and Installation Modularity
The Retro Iron circuit — Carnhill output transformer and John Hardy 990C discrete op-amp on the stereo bus — operates identically to smaller HE configurations: independently switchable Retro and Iron modes, each adding a distinct character, with Low Bump and High Lift mix bus EQ available before the output faders. The VCA stereo bus compressor with adjustable threshold, ratio, auto-release, and GR metering operates post-insert, pre-fader. The console is semi-modular: each of the six 12-channel bays and the master section are independently serviceable and replaceable. Bay order, master section position, patchbay integration, DLC placement, and Producer's Desk inclusion are all determined at order — every unit is hand-assembled to specification at Audient's Hampshire factory. At 72 channels, power is distributed by two ASP8120 Ultra supplies running in parallel, both deployable in the control room without a separate machine room, thanks to low-noise transformers and low-RPM fan cooling.
