The TG12410 Post Production console.
There was a requirement at Abbey Road for a disk transfer console, for use in the studios extensive number of disk cutting rooms. The circuits were based on the electonics of the TG mixing desk, and the subsequent design was given the designation TG12410. Two versions were produced, one for disk cutting and the other as a tape to tape facility, which allowed up to four track transfer and monitoring. The company were still actively committed to "Quadraphonic" recording at this time, which is why the desk was capable of four channel working. These post production consoles were a great success, and were produced in significant numbers. The design was so good that several of these consoles are still in daily use at Abbey Road in transfer and remastering rooms.
Many of EMI's overseas operations were purely record companies and had no local studio facility. The master disk cutting was done locally, so there was a greater demand for post production equipment than for studio consoles. As a result there are more of these transfer consoles around than the mixing desks.
The transfer consoles were highly modular in construction, which has meant that many have been "parted out" to allow use of the individual units, such as equalisers and limiter/compressors as stand alone or rack mounted items.
