EMI TG12345

It didn’t shape sound — it shaped track count.

The TG12345 was Abbey Road’s first solid-state console, installed in late 1968 to enable 8-track recording. It had 24 mic inputs, 8 tape outputs, and per-channel compression and EQ — a leap from the tube-based REDD .51 and the four-track Studer J37. It did one thing decisively: expand track count while integrating dynamics and tone shaping into every channel. It offered no automation, no recall, and no adaptability beyond that fixed architecture. It belongs in a working historical studio, not a modern hybrid setup.

The written brief1 min read

What it is and what it was built for

The TG12345 is a solid-state mixing console built by EMI for Abbey Road Studios. It was built to replace the REDD .51 and enable 8-track multitrack recording.

How it works, in terms a player would use

It has 24 mic inputs and 8 tape outputs. Each channel has built-in compression and EQ. It is solid-state, not tube-based.

What it does better than anything else

It enabled simultaneous 8-track recording at Abbey Road Studio Two in late 1968 — the first console there to do so with integrated per-channel dynamics and EQ.

What it does badly

It offers no automation, no recall, no monitoring matrix beyond its fixed signal path, and no digital integration. Its per-channel processing cannot be bypassed or re-routed.

What people made with it

It was used to record albums requiring 8-track capability after late 1968 at Abbey Road Studio Two, following the switch from the four-track Studer J37 to the eight-track 3M M23.

Who should use it, and who should not

Only studios committed to authentic late-1960s EMI hardware workflows should use it. Anyone seeking flexibility, recall, or modern routing should not.

Is it worth your time

It is worth your time only if you are restoring or operating a period-accurate Abbey Road–style 8-track workflow. It does not translate to modern DAW-based production as a tool or a sound model.

EMI REDDEMIThe EMI REDD was not a product. It was Abbey Road’s first custom-built, vacuum-tube-based stereo mixing system — engineered in-house, adapted for four-track tape, and retired when it could not scale beyond four outputs. Its sound came from saturation, not precision. Its limits were physical: fixed routing, no patching, no serviceability. Its legacy is inseparable from the room, the tape machines, and the engineers who worked it daily.

Vestax PMC-25VestaxThe Vestax PMC-25 is a 2-channel DJ mixer designed for house music. It is 3U tall and rack mountable. It features PGM vs. Master LED VU metering, split cue, a third cueable aux input, and EQ kill switches implemented as mini faders to avoid clicks and achieve -85 dB attenuation. The crossfader has a fixed curve. Faders and crossfader are replaceable. Sound quality is perceived as superior to a cheap Numark mixer.

Apogee Rosetta 800ApogeeThe Apogee Rosetta 800-192k is a rack-mountable analog-to-digital converter. It connects via rear-panel analog, ADAT, and AES. It serves Pro Tools HD systems. It runs at 48 kHz, 96 kHz, or 192 kHz. It produces a clean, transparent, smooth signal. It does not do D/A, preamp, or processing.

Focusrite VoiceMaster ProFocusriteThe Focusrite VoiceMaster Pro is a vocal-optimised channel strip with a discrete Class A preamp, optical compressor, de-esser, and tube simulation. Its preamp is soft in the highs. Its compressor is transparent. Its EQ is functional but unmusical. All controls are front-panel only. It delivers what vocal tracking needs—not what mixing demands.
