The Mäag Audio EQ4-500 is a single channel 6-band equalizer module that fits into a single slot of the popular 500VPR series racks. Like the EQ2, many features and the design philosophies of the Mäag Audio EQ4M standalone equalizer are incorporated into the EQ4-500 Series equalizer.
Like the 1U standalone Mäag Audio EQ4M stereo mastering equalizer, the EQ4-500 has six EQ band sections divided into four, fixed frequency bell-shaped peaking equalizer sections, a 2.5 kHz shelving equalizer section, and the Air Band shelf equalizer with a choice of: off, 2.5, 5, 10, 15, 20, and 40 kHz frequencies. The five frequency bands in the main section are: Sub or 10 Hz, 40 Hz, 160 Hz, 650 Hz, and the 2.5 kHz shelf EQ. The Air Gain allows for up to +20 dB boost for the Air Band shelving equalizer.
The five EQs in the main section have a boost/cut range of +15 dB and -4.5 dB with center position detent at 0 db. The EQ4-500 has both a green signal present LED at -20 dBu and a red peak LED that flashes with +23 dBu peaks. There is also an In/Out bypass switch for the entire module.
The Mäag Audio EQ4-500 Series 6-Band Equalizer is the ultimate equalizer for any 500VPR rack owner that, along with the access to the Air Band, will become your first “go to” tool for both recording and mixing duties.
