Control Elements

Phase reverse

The phase reverse function reverses the polarity of the microphone signal, inverting the

phase (by 180°) to correct phase-inverted signals caused by multiple signal sources. A voice-

over artist, for example, hears himself during recording through the headphones and simul-

taneously through the bones in his head. Phase inversion will cause an unnatural sound, and

even minimal variations in distance to the microphone will cause drastic variations in the

sound. Phase inversion is also commonly encountered when using multiple microphones on

a single sound source. We recommend checking for correct polarity before each recording.

Phase reverse can be applied to the preamplier microphone and line inputs.

High-pass filter

This switch activates the high-pass lter, which operates from 85 Hz downwards with 6 dB/

octave (often also called a “rumble lter“). The lter prevents the amplication of unwanted

low-frequencies. Compared to 12 dB/octave lters, the 6 dB lter works relatively moderate,

but very musical.

The high-pass filter can be applied to all three preamplier inputs (microphone, line, and

instrument).

PAD

The PAD switch attenuates the microphone input by 20dB. High-level input signals can be

attenuated in order to prevent over-driving the preamplier. The Frontliner has a minimum

pre-amplication of +13 dB. But with signals from drums or brass this may already be too

much. Engaging PAD attenuates the minimum pre-amplication (MIC GAIN control fully

counter clockwise) to -7 dB, thus providing a useful gain control range for loud input signals.

INSTRUMENT input

The INSTRUMENT input jack is placed on the front for easy access. It should be used to connect

instruments like e-bass and guitars, acoustic guitars with pick-ups, etc. The Instrument input

features a 1 MOhm (one mega Ohm) input impedance. Line signals with lower impedances,

such as from D/A converters, samplers, synths, etc. should be connected to the rear LINE IN

socket.

IMPORTANT: As long as an instrument is plugged into front INSTRUMENT input, the rear

panel LINE IN input is deactivated.
