HF equalizer from the NSEQ-4 in 500 format.
The Millennia NSEQ-HF is a single-channel analogue equalizer in API 500 format and is based on the low-noise circuitry of the NSEQ-4. The fully discrete EQ focuses on the high frequencies. It offers a choice between shelving and peak filters and a selectable operating range of six different frequencies. The gain is adjusted via the associated potentiometer with 21 detented steps. In addition, there are switches on the front panel of the NSEQ-HF to adjust the gain range and an input switch to compensate for the 6dB level difference when using an unbalanced input signal. A true hardwire bypass ensures that the signal is not affected in any way when the unit is set to Off mode. The equalizer's housing is made of sturdy metal and the front panel is made of high-quality brushed stainless steel.
