Denmark Gryphon Guifeng Zena Zena pre-class Vectra licensed authorized agent
Elegant styling in the same line
The line of the fuselage is exactly like the Danish Gryphon Audio Zena pure A fully balanced preamp. It is an advanced and upgraded version of the acclaimed Athena dual mono preamp. The panel is equipped with a touch-sensitive backlight activation function, and the display screen can be adjusted for multiple different brightness levels. As for the flexible and flexible function setting menu, it provides fine-tuning of the source input and green bias adjustment for the Gryphon rear stage.
True dual mono pure class A zero feedback discrete amplifier circuit
The amplifier circuit of Zena Zena''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s front stage adopts a true dual mono pure class A zero feedback discrete design, and the inter-stage coupling is performed in a servo-monitoring DC direct connection method to create a 1MHz ultra-wide frequency response. The brand-new pure Class A single-ended input buffer stage combines high-speed, open and transparent characteristics. The low-inductance sealed gold-plated contact relays and the new 43-stage progressive tactile adjustment full-balanced audio control system composed of high-precision surface-welded metal resistors ensure that each level of signal only flows through two resistors , Adhere to the concept of high fidelity in an all-round way.
Both input and output are equipped with RCA and XLR connection terminals
On connection, Zena Zena''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s pure class A fully balanced front stage provides 3 sets of RCA and 2 sets of XLR high-level inputs, without additional wiring, Neutrik XLR directly connected to the circuit board and polytetrafluoroethylene as insulation material The RCA terminal further reduces signal loss. A section of the power cord from the IEC socket on the back of the machine to the power switch is also stored in the shielded channel to prevent the possibility of interference caused by the 50/60 Hz mains frequency. In addition, the fixed output AV through-car interface specially designed for AV audio and video systems can also correspond to XLR and RCA connection terminals at the same time.
The power supply part enjoys 52,000 microfarad capacitors as energy storage
The integrated design of Zena Zena''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s pure class A fully balanced pre-stage, its power supply link layout is also quite particular, not only uses Schottky diodes and 52,000 microfarad capacitors as energy storage, but also uses a shunt design for the voltage regulator. The audio control part also uses organic polymer aluminum capacitors and German Wima polypropylene film capacitors as bypasses to create the best noise suppression effect.
Can be equipped with phono amplifier or decoding module
Zena Zena For users of pure Class A fully balanced pre-amplifiers, you can also add PS II MM/MC phono-amp module and a dedicated D/A decoder module for Zena, which will add more fun.
