IGS Audio Double Triode Limiter (DTL) is more than ‘just’ a classic tube triode microphone preamp. The old-fashioned design was upgraded with a musical opto-limiter, based on a circuit used in 60’s and 70’s.
The Preamp.
DTL is a tube microphone preamp adapted to work with any type of microphone. A wide range of amplification makes it possible to record drums as well as the quietest ribbon microphone. DTL does a great job of recording tracks from external devices such as synthesizers or drums machines (like Akai MPC). Great results are achieved with reamping tracks from DAWs. DTL adds a nice tube saturation to the sound. The high impendance inputs (HiZ) allow for connecting an electric or bass guitar directly into the grid of the first step of tube amplification (Typical HiZ solution).
The Limiter
Additional device capabilities are activated by the Limiter section. This can be used to limit peak levels of the input signal. The component in charge of compression is an IGS Audio custom designed photocell. It can improve the overall dynamics of the mix and give it a brighter sound. This is a very versatile device for audio processing.
Full of features.
The audio path of the preamp is a two-stage tube amplifier with an individual drive on both steps.
