Ultra-high Performance Analogue Line Preamplifier using new Goldmund ultra-low noise analogue technology.
Full Dual-Mono construction with processor driven attenuators linked.
Uses 2 x Goldmund 22S modules (one per channel) with temperature control.
Separate built-in power supply unit for optimum noise reduction.
3-step regulation in the power supply with 8 separate circuits.
7 x inputs and 2 x analogue tape loops. 3 inputs with balanced or unbalanced.
Balanced and Unbalanced analogue output circuits.
