SPL Track One Channel Strips

SPL Track One Channel Strips Overview:

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.

Mic/Instr./Line Preamp
The Track One is equipped with two preamps: a microphone preamp with 48V phantom power and a separate instrument preamp. Both are tuned to a sound-neutral, open and transparent characteristic. The low-cut filter can be used for both preamps.

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.

The Auto-Threshold control maintains constant processing even if the distance between the singer and the microphone varies. Operation is reduced to just one knob that sets the desired S-reduction.

Compressor / 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.
