Chandler Limited and Abbey Road include EMI TG Opto and TG12345 MKIV to 500 Series
Chandler Limited, the only company in the world authorized to develop, manufacture and market the
‘Official Equipment’ of EMI/Abbey Road Studios, has expanded their 500 Series palette with additions
of the TG Opto compressor and TG12345 MKIV EQ to its EMI/Abbey Road Studios historic lineup.
The TG Opto compressor borrows from the TG1 Opto counterpart, first introduced as part of the Chandler
Limited TG Microphone Cassette in late 2016, and the modern studio classics, the TG1 Limiter, and
TG12413 Zener Limiter. The TG Opto compressor for 500 Series is a double space, mono module, featuring
continuous input, output (makeup gain), attack and release controls, sharp and rounded knees, and true
bypass. The continuous controls, coupled with the option of sharp or rounded knees, allows the TG Opto
to go from explosive on drums to subtle on sources such as vocals, where less obvious compression is
desired.
The TG12345 MKIV equalizer for 500 Series is a single space, mono module, featuring a presence and bass
control-set, as found on the historic EMI TG12345 recording and mixing console microphone cassettes. The
presence section is a bell type with eight frequency options and out position, while the bass control is
a dual frequency selectable shelving type.
