The SR24 is a two channel, four band equaliser in a two rack-space chassis. With a dedicated knob and/or switch for each control function, the SR24 is easy to use; by utilising continuously-variable controls for both the frequency and boost/cut, the SR24 can be very precise in applying equalisation to the selected audio material. The SR24 circuit design is deeply rooted in API’s history. From the late 1970s to the early 1980’s, an audio company called "APSI" manufactured consoles and equalisers. Their 562 module was a 4-band, fully parametric equalizer which was designed by APSI and sold through API. Over the last several decades, these EQ modules remained a favorite among many studio engineers, but have become increasingly difficult to find. The SR24 is a faithfully re-engineered version of the original 562, offering the user 2 channels of classic analogue EQ in one rackmount unit. 4 bands of equalisation modeled after the classic APSI model 562 EQ Each band offers continuously variable control of frequency and gain, using separate knobs 12 dB of boost/cut per band All 4 bands are peak/dipping parametric configuration Custom transformer balanced output Fully balanced 1/4" and XLR input and output Massive headroom +24 dB clip level
