Crane Song Insigna Frequencies

Let's have a closer look at the frequency ranges you'll get to work with.

The high pass filter ranges from 25 Hz to 150 Hz (25 - 40 - 50 - 60 - 90 - 120 - 150) and the low pass filter from 6kHz to 20 kHz (6 - 7.5 - 9 - 10.5 - 12 - 15 - 20).

The filters will give you enough power to clean up low rumble, tidy up the low end on LF centric instruments and control harshness at the top like guitars for example.

On the other side of the spectrum, the LF band shelves from an extremely low 10 Hz up to 200 Hz. Straddling the middle, the MID peaking band deals with anything from 150 Hz to 7.2 kHz and is centered around a proportional Q (bandwidth). All three bands give you +/- 12 dB boost and cut.

About Crane Song

Crane Song owner, founder, and design engineer Dave Hill has become one of the most respected inventors in the professional audio business. Dave has been doing studio and film sound recording since 1972. Early in the 1980's Dave was asked by a used equipment dealer if he could design a tube compressor that would have the sound of the older tube type devices and still be clean enough to compete with modern devices. The result was the Summit Audio TLA-100. Building on the success of that first design, Dave went on to design multiple tube devices, giving Summit a premier position in pro audio. In 1995 Dave founded Crane Song, a company offering innovative solid-state hardware and software used at the highest levels of pro audio.
