Arrel Audio R-502

3 Band Parametric Equalizer (9 Center Frequencies)

R-502 is an advanced single-channel parametric equalizer conceived to offer to the API 500 user the superior audio performance of the ARREL Audio high level series products. the unit offers to the 500 user high reliability, rugged design, outstanding audio quality, versatility and ease of use typical of the tradition of ARREL Audio products.

The R-502 equalizer is based on the Livio Agentini’ s “Single-Stage Parallel Configuration” patented design. This innovative phase coherent EQ design offers the lowest distortion/noise specifications, not available in other products.

The R-502 filtering section offers three band LO, MID, HI controls (bell shape). The emphasis/de-emphasis control range is +/-14 dB, the three primary bands become nine by using three center frequency switches. The Q control value (narrow, mid, wide) is selected by three switches (one for each band).

A bypass button is used for a true analog by-pass function (LED).

R-502 is the first of the serie of equalizer that ARREL Audio conceived for the 500 series (the other models are R-503, R-504, R-505) in order to give to the user the best choice for its application.

R-502 is dedicated (due to his absolute sonic level quality) to high professional vocal recordings, classical instruments, high dynamic range instruments such as drums and percussions.
