The 2623-4-L is a custom made audio output transformer. The 2623-4-L has been designed to replicate the transformers found in the vintage API recording consoles from the 1970's. This PCB mount transformer was used on the 4 channel ACA's in the vintage consoles. This transformer was also used to balance the "preamp out" and the "direct out" amplifiers (Flying lead version, 2623-1), Echo send modules, Master Cue modules, some of the 500 series modules and of course the talkback mic pre amp!

To my knowledge, a Litz wire version of the 2623-4 has never been realized. As for other Litz wire output transformers, the Litz wire version of the 2503 has occasionally been referred to as the "preferred" sounding version of this popular quadfilar transformer. Litz wire is a type of cable made up of multiple strands of wires electrically insulated from one another and twisted together in a prescribed pattern. It has been said that winding with Litz wire produces a more uniform high frequency response but we have also noticed the bottom end seems to be a little "bigger" and "deeper".

The 2623-1-L can easily be distinguished by the red keeper lamination and the sexy black bobbin.

The 2623-4-L has a common PCB footprint that is identical to it's predecessor, the AP2623-4
