Product Description

Recording Channel AD w/ Digital Output

The flagship channel strip.

The Frontliner has all tools on board to record vocals and instruments in perfect quality: it merges a preamp, a de-esser, an EQ, a compressor and tube saturation.

Thanks to it's individual analog I/Os, all these powerful, hi-end analog processors can be use not only while recording but also during mixing. The Frontliner is therefore not reduced to a front-end device. Especially DAW based studios can integrate high-grade analog processing at any stage of the audio production process.

  •  Three separate, individually optimized inputs for microphones, line signals and instruments.
  • Discrete transistors/tube hybrid preamplifier to combine the advantages – high dynamic range and low noise operation of semiconductors with the musical qualities of tube sounds (appealing top end, beautiful spacial impression). 
  • 250 volts tube circuits in the preamplifier and for tube saturation stages.
  • High-grade operational amplifiers from Burr-Brown at critical positions.
  • The De-Esser applies SPL's method of phase cancellation for reducing sibilants. This innovative approach works much more neutral than traditional compression methods – a unique method for unobtrusive results and extremely fast operation.
  • The compressor is operated by SPL’s double VCA drive circuitry. A differential stage eliminates side effects and the half load per VCA dramatically reduces THD.
  • The operational amplifiers for the compressor circuitry meet military specifications. Therefore the regulating voltages are extremely precise – a precondition for high signal processing quality.
  • Selected condensers for the EQ filters with pleasant sound characteristics. Especially with vocals, amplified frequencies are not sounding too bright, and on the other hand reductions can tame harsh sounds without sounding dull.
  • Central star ground wiring scheme minimizes influences that could affect the ground paths. The audio ground is separated from the ground of the remaining equipment. This leads, in the truest sense of the word ”clean”, to considerably improved tonal quality.
  • The power supply is built around two toroidal transformers, one for the audio voltages and one for the other supply voltages (tube heating, LEDs, micro controller etc.) Mutual interferences are excluded and lavishly over-dimensioned capacities ensure absolutely stable supplies for all audio circuitries.
  • Options include 24/192 AD converter and in/output transformers by Lundahl
  • Made in Germany
