Here's what Chandler Limited say about the TG12345 MKIV EQ:
The Chandler Limited TG12345 MKIV equalizer is a handmade, fully discrete, mono, single space module, designed for the 500 Series format.
The TG12345 MKIV EQ for 500 Series, inherits from Chandler Limited’s TG Microphone Cassette and flagship TG12345 Curve Bender, and draws its heritage from the input and group channel equalizers found on historic EMI TG12345 recording consoles of the late ‘60s and early ‘70s.
The TG12345 MKIV control-set includes: presence and bass bands, with continuous boost/cut, and true bypass. The presence band is switchable, featuring eight frequencies and an out position. The first seven frequencies are bell type, and the eighth is a shelf at 10 kHz. The bass band is a shelving type, featuring two frequency options, 90 or 150 Hz.
The remarkable character of the TG12345 MKIV EQ is silky smooth and the sound is Curve Bender sweet. Create an EMI TG console channel today by adding the TG12345 MKIV EQ, TG Opto compressor and TG2-500 preamp to your 500 Series rack!
Chandler Limited is the only company in the world authorized to develop, manufacture and market the “Official Equipment” of EMI/Abbey Road Studios.
Conceived from meetings in 1967 between Abbey Road engineers and EMI’s Central Research Laboratories technical team, the EMI TG12345 desk (later known as the Mark I), would usher in a sea change in sound and flexibility at Abbey Road Studios.
The new transistor based EMI TG12345 recording console was modular in design, with twelve dual channel microphone cassettes. The TG desks featured expanded EQ, and for the first time ever, a compressor/limiter on every channel.
Installed in Abbey Road’s Studio Two in November 1968 and making its debut on an 8-track recording by the Shadows, the new transistor desk marked a departure from the earlier REDD valve consoles. The following year, the EMI TG12345 desk helped shape the sound of the Beatles’ final album, Abbey Road, which was markedly richer sounding to that of the band’s earlier work. The sonic qualities of classics like “Here Comes the Sun,” “Come Together” and “Something” would have been very different without the EMI TG12345.
