With up to +72 dB of gain available on the mic preamp, the SiX CH delivers bountiful boost for low-output ribbon and dynamic mics or even the quietest of sources. Of course, switchable 48V phantom power is provided for condenser mics. You can also keep the low-end power under control by activating the 75 Hz high-pass filter, which features a 12 dB/octave slope. Each band of the equalizer can be set to shelf or bell mode; different center frequencies are used for each mode to increase flexibility. The compressor utilizes variable threshold and automatic makeup gain to enable fast operation and consistent output level.
