SPL Audio Frontliner AD w/ Digital Output

Recording Channel

SKU: SPL00031 Categories: , , , Tag:


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.

The Frontliner features three separate, individually optimized inputs for microphones, line signals and instruments.
The microphone input features 48V phantom power, phase reverse function and a subsonic filter.
The low-impedance Line input has a precise balancing stage for connecting studio equipment.
The low-noise, high-impedance instrument input is easily accessible on the front panel.
