The VXP's mic preamp contains a Class-A discrete input buffer followed by a dual-servo gain stage. There is a front panel 48-volt phantom power switch along with a -20db input attenuator pad. The compressor features 16 preset,compression ranges, from light to medium to heavy, designed for vocals while the expander section has dual-concentric control knobs for setting threshold and ratio.

The variable de-esser has a range of 800Hz to 8kHz for removal of unwanted, sibilant distortion. The four-band equalizer starts with a high-pass rumble filter and continues with both a low-pass and high-pass shelving filter coupled with a dual-band, mid-range equalizer.

Options include a 24-bit/96 kHz stereo A/D converter with both AES/EBU and S/PDIF outputs. Since the VXP is a single-channel unit, there is the ability to add another VXP unit to the converter for two separate channels of digital conversion at the same time.
