Zeus Ultima is a hybrid phono preamplifier with 2 turntable inputs (MM & MC). It uses ultra low noise operational amplifiers at the inputs and a tube buffer output stage.

It features multiple input resistance, input capacitance and gain selections. Sophisticated power supplies are utilized to deliver the best DC voltage to each stage separately. Zeus provides two output connections, 1 RCA and 1 XLR connected in single ended manner. It can be turned in true balanced upon request. Zeus is remote controlled. All electronic components are through hole type silver soldered by hand.

Each input of Zeus Ultima is separately configured in all parameters (MM/MC, input resistance/capacitance and gain) and stored in memory. This can be done thru the knob on the face plate and the display or via the remote control. The values for input resistance, capacitance and gain are selected via high quality signal relays.

Gold plated RCA and XLR connectors are implemented for the signal inputs/outputs.

An elegant remote control in aluminum case offers you control over all the functions of Zeus Ultima phono preamplifier. Input selection and parameter settings for each input.

Carefully selected values and types of the electronic components contribute to the reliable circuits operation and the high sound quality of the preamplifier. Mundorf Evo silver gold oil capacitors and premium quality tube are used in Zeus Ultima for superior audio performance. The meticulous PCB design ensures excellent behavior in SNR, distortion and channel separation.

Inner signal wiring with high quality shielded signal cable. Power wiring uses high quality copper cables of more-than-needed AWG gauge, to achieve low impedance power transfer. All power cables are twisted in pairs to minimize the electromagnetic interference.

The handmade power transformer is thoroughly tested for quality and reliability. The positioning of the transformer is such that minimizes the magnetic interference with the sensitive circuits of Zeus Ultima. Furthermore the transformer has copper foil shielding.
