GC Audio introduce a new preamp cartridge designed by Graham Langley, co-founder of Amek and designer of many large format mixing consoles (Amek Mozart, Rembrandt, Angela, etc...).

This new design, exclusive to the Inherit system, has been designed to make the best use of the resources offered by the reception rack.

The synoptic is a premium differential preamp composed of paired transistors and constant sources. It is digitally controlled in order to isolate the analog signal in the metal cartridge (and therefore separated from the radiation of the linear power supply). Common mode rejection and output balancing are manual for each cartridge manufactured to achieve optimized values. The resistive ratios are composed of low value in order to obtain an optimal EIN.

This preamp is perfect for the user who wants uncompromising sound pickup with a transparent and powerful result.

A gain range ranging from 16dB to 60dB in 4dB steps has been chosen.

PAD = -20dB

Input Impedance = 5K Ohms.

EIN (150 Ohms source @ 60dB, 22hz/22Khz) = Better than -127dB.

THD + N = 0.04%

All measurements were made with Audio Precision Device, 150 ohms Input load and 100 Kohms output load.
