HVA-NEQ Parametric Mastering Equalizer


The High Voltage Audio HVA-NEQ parametric equalizer is a powerful, dual-channel mastering EQ designed with the professional mastering engineer in mind. Each channel features four precise fully parametric bands, each with a variable Q/shelf, frequency and cut/boost controls with gain multipliers, low and high pass filters, and a switchable mid/side matrix to allow for greater flexibility with program material. All controls are stepped, allowing for precision recall and stereo tracking.

All four bands and low/high pass filters can be independently switched in or out, allowing for the efficient auditioning of each band or filter. Each band is equipped with an adjustable Q control which adjusts the bandwidth of each band. The low and high frequency bands are equipped with a switchable shelf, perfect for adding low end energy or high frequency sheen.

The gain multiplier toggle switches allow for the fine tuning the amplitude of the cut/boost switches. This allows for minute corrections to be performed with the x½ multiplier or larger cut/boosts with either the x1 or x2 multiplier selected. The powerful gain multiplier feature allows for the HVA-NEQ to be easily adapted to mixing applications where a greater cut/boost range is desired. Each gain switch can be instantly toggled between cut, boost, or band-bypass.

The HVA-NEQ features a high efficiency, EMI filtered switch mode power supply with additional filtering added to ensure clean, interference-free performance with a universal input voltage range to cater for all regions.
