Danish Gryphon 's new Zena preamplifier is a true Dual Mono Pure Class A (Pure Class A) zero-feedback discrete amplification circuit, using a servo-monitored DC direct connection method to create a 1MHz ultra-wide frequency response . New pure Class A single-ended input buffer stage, combining high speed, openness and transparency. The new 43-segment progressive touch-adjusted fully balanced sound control system is composed of low-inductance sealed gold-plated contact relays and high-precision surface-welded metal resistors, ensuring that each level of signal only flows through two resistors. , fully adhere to the concept of high fidelity.
The inputs and outputs are equipped with both RCA and XLR connectors. Zena provides 3 sets of RCA and 2 sets of XLR high-level inputs without the need for additional wiring. Neutrik XLR and RCA with PTFE as insulating material are directly connected to the circuit board terminals to further reduce signal loss. In addition, the AVbypass function specially designed for AV audio and video systems can also support both XLR and RCA connection terminals.
The layout of Zena's power supply is also very particular. The power supply part has 52,000 microfarad capacitors as energy reserves. Not only does it use Schottky diodes and 52,000 microfarad capacitors as energy reserves, the voltage stabilizing part also adopts a shunt design, and the sound control Some also use organic polymer aluminum capacitors and German Wima polypropylene film capacitors as bypass to create the best noise suppression effect!
Zena can also be equipped with the latest PS2-S MM/MC phono stage module and D/A dedicated decoding module to add more fun.
