Product Infomation  

New Design

Entirely new is the design, with the clear, unflappable and classical form of the Audionet 4-key medium format with high-quality materials and finely detailed features. SAM G2 comes either with a silver or black front panel and a red or blue display. Additionally, you can extend the SAM G2 with our high-quality phono preamplifier board for MM and MC pick-ups.

Six inputs, one of which is symmetrical, two switchable pre-stage outputs for end stages, subwoofers or recording devices etc, of which one is controlled, the other a fixed by-pass module for integration in a home cinema system. A switchable headphone output, automatic mains phase recognition and Audionet Link remote switching as well as its large display make the new SAM G2 a comfortable allrounder leaving no wishes unfulfilled.

 

Architecture

The complex SAM G2 circuitry is complex, technically unique and radically realized. The input signals are received from gilded, Teflon isolated cinch jacks and then led further via gold-doped pure silver solid core signal cabling and gold-contacted double anchor precision relays, which switch the input signals. The symmetrical input signals are divided into channels beforehand.

The mains supply is extremely potent and very fast. This is guaranteed by a capped and fused 700 VA toroidal transformer, selected main capacitors with a total of 96.000 F filtering capacity, a specially developed input filter and highly pure silver cabling as well as a capacitively optimized layout with the shortest of supply routes. Working stress is smoothed and stabilized by fast-working, discreet, local degenerated pre-regulators.

As with all our mono and stereo end stages, we have also developed our ultra-linear amplifier concepts further in the new SAM G2. The circuitry is designed for exemplary distortion-freedom, speed and stability. The SAM G2 is conceived so that the two channels can work as independently of each other as is possible. Influences from the amplifier which could damage the sound have been almost entirely excluded, guaranteeing exemplary reproduction stability.

We use only the best materials, carefully selected, high-grade components such as High Audiograde electrolytic capacitors, with a silk dielectric; high-quality, close-tolerance film impulse capacitors and high-quality silver / gold yaw for internal cabling.

 

Control

The SAM G2 is controlled via a high-performance flash microcontroller. Software upgrades are very easy. The controller makes for simple operation, comfortable functions and reassuring stability. The control programme enables operator-friendly access to comprehensive and practice-oriented functions. For example, the two pre-stage outputs and headphones output can be switched electronically. A by-pass mode is available for smart integration of the new SAM G2 into a home cinema system.

The inputs are freely nameable and the controller even verifies that the mains connection is phase correct. Moreover, the controller monitors all operating states and deactivates the device as soon as a critical state has been identified. A large graphical-capable display with max. 4 x 26 characters informs the operator of all operating states and settings. The SAM G2 is equipped with AudionetLink as a matter of course. This enables the isolated activation of other Audionet devices via fibre-optics.
