Cranesong

The Crane Song a valve-based tube EQ for the 500 format. Using a dual triode circuit with a 12AX7 tube, Dave Hill’s latest creation features three bands and filters. Breaking it down, the EQ has 24 dB/oct high pass and low pass filters, each with seven frequencies: the top and bottom band are shelving, each with eight frequencies; and the mid band is peaking with eight frequencies.According to Crane Song, the three bands work by using buffered RC circuits in the negative feedback path around the tube amplifiers. The result: a fat sounding EQ rich in second harmonic triode tube color. Crane Song Insigna is 3-band valve EQ for the 500-series format with high and low cut filters.Crane Song Insigna features at its core, a dual triode circuit with a 12AX7 tube. All the three bands offer a selection of eight centre frequencies with both the Low and high band being shelving bands. Buffered RC circuits are used in the negative feedback path around the valve amplifiers for an impressively fat sound rich in second harmonic.The High-Pass and Low-Pass filters use steep 24dB/oct filters and offer a choice of 7 frequencies each.Χαρακτηριστικά:1-slot 3-band EQ for 500-series formatHigh and Low shelving bandsPeak Mid band24dB/oct high pass and low pass filtersFat sounding and rich valve sound

IBIS is an analog equalizer that boldly takes equalization to a new level of musicality. Each of its four bands features switch-selectable frequencies centered on and covering musical-step intervals from 32-Hz "C" to 22.35-kHz "F." Its four overlapping bands are labeled with note names and frequency allowing for the first time a "translation" between musician-speak and engineer-jargon. The bandwidth control has similar notation with adjustment from 0.2 octave to 4 octaves per band and a boost / cut range of 12 dB.The low-cut filter is switch selectable from 20-Hz to 150-Hz with slopes of either 12-dB or 24-dB per octave. Like most Crane Song products, IBIS utilizes discrete class-A circuitry and features a truly unique and adjustable "color" function that can be applied to either the entire audio path or to any individual frequency band. A fully stepped mastering version is also available.
