SPL

Description

The Track One is a fully equipped channel strip for fast and reliable voice and instrument recording, meeting the highest demands on sound and reliability.
Features
Mic/Instr./Line Preamp
  • The Track One is equipped with two preamps: a microphone preamp with 48V phantom power and a separate instrument preamp.
De-Esser
  • The Auto-Dynamic De-Esser unobtrusively and effectively removes disturbing S-sounds by detecting only the “S-frequencies” and reducing them by phase cancellation.
Limiter
  • The compressor is also extremely easy to operate via a controller; its strength lies in its unobtrusive, musical operation. The compressor/limiter section has excellent noise and distortion data.
Equalizer With Air Band
  • For Track One, an EQ section has been designed specifically for processing voices and acoustic and electronic instruments. The Air Band filter works on the basis of a coil/condenser filter.
Output & Metering
  • The variable Output helps adjusting the gain to optimally drive following equipment.
  • In the display the output level, S-Reduction activity, signal presence and overload as well as the compressor’s gain reduction are shown.
