The IGS DTL Tube Microphone Preamp & Limiter gives you a wonderfully vintage, 2-Channel, classic tube triode microphone preamp combined with a stereo tube custom photocell limiter. Versatility is the IGS DTL's specialty.
The IGS DTL Tube Microphone Preamp & Limiter is more than classic tube triode microphone preamp. The old-fashioned design was upgraded with a musical opto-limiter. The limiter is based on circuit used in 60’s and 70’s.
The Preamp
The IGS 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. The IGS 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. The IGS 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. When the limiter is working it is indicated by a LED labeled “Limit” on the front panel. The limiter controls the louder parts of the signal and prevents from the digital clipping at the inputs of you ADC. Another trick could be using the IGS DTL as a drum compressor or mix buss compressor. 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 individual drive on both steps. The saturation at the first step depends on the input signal level (with possibility to use Pad -20dB). The saturation of the second step is dependent on the Output regulator. Inputs and outputs are balanced with IGS's own custom transformers. The anode voltage is set close to 300V DC. For each of the channels Output and Limiter threshold can be regulated smoothly. The featured switches are: GAIN, +48V, Mic/HiZ, Phase, Pad -20dB. Hi-Z inputs are located on the front panel. The meters show output signal level.
