Schertler crosses over into pro audio
Published: PRODUCTS
Swiss manufacturer Schertler has developed a modular mixer that can be designed and built by the user. Named Arthur (Format48), the mixer is created from a choice of eight different Class-A input/output modules, which can be combined in any order and quantity. Arthur’s electronic design is characterised by its absence of negative feedback (NFB) from input to output, reportedly resulting in fast response and a natural attack. All circuits are built using discrete components and pure high-voltage DC-amps without any capacitors in the signal path, providing 30dB headroom and low noise. To combine the modules, the user can change the unit sequence or add further units at any time.
The manufacturer has also announced Tim and Tom, active analogue 2.1 amplification systems that each integrate an active subwoofer with a linear power supply and two passive satellites. Whilst Tom has an increased power capability of 1,000W, the sub levels on both systems can be adjusted from -7dB to +2dB. A new mono/stereo switch has also been added. Finished in wooden or anthracite grey finishes, the satellites incorporate a passive crossover with a custom coil.
Lastly, the YellowMic 500 microphone preamp range consists of single channel, full Class-A, 500 series preamps in commercially available Lunchbox racks. Available in three different models - MIC500-TL, -TO and –TT, the preamps feature intuitive controls and discrete electronics, with no negative feedback applied for faster attack and improved slew rate. The Unico acoustic amplifier series is a re-engineered five-channel version of the company’s original Unico Classic/Deluxe amps, but with increased power output (250W) and a new 10-inch subwoofer. Unico features a Class-A preamp with no integrated circuits or negative feedback.
