Designed by Paul Wolff, a prolific engineer with four decades of experience in equalizer design, and named FREQ by Terry Lewis, who was the first to adopt it, this product has a rich audio heritage. The FREQ possesses the desirable characteristics of classic proportional-Q equalizers, with the characteristic wide Q that narrows as you boost or cut. Paul took it a step further. Instead of stopping at one octave, he added 1\/3-octave capability. This makes it possible to perform a narrow cut with the same EQ.     <\/p>\n<p>The front-panel controls, together with the proportional Q control, provide all the gain controls.<br \/>\nThe less extreme equalizer settings have a wide bandwidth, while the more extreme ones have a narrow bandwidth to eliminate ringing issues. The HIGH and LOW bands feature an additional WIDE mode that adjusts the Q to a fixed 3-octave-wide filter without the infinite frequency response of a typical shelving equalizer. Since the WIDE mode gradually tapers off at the ends of the passband, this prevents out-of-band frequencies from causing clipping in the HF and LF ranges.  <\/p>\n<p>The two MID bands include a 1\/3-octave bandpass filter that allows you to surgically cut problematic frequencies with narrower cut-off settings than would normally be possible in proportional Q mode. Regardless of the mode you use, the FREQ is designed to optimize your musical sound. <\/p>\n<p>The FREQ features a custom Cinemag nickel-and-steel output transformer, the preferred choice for transparency without coloration.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>&#8211; 4-band with Proportional Q.<br \/>\n&#8211; Cinemag nickel and steel transformers.<br \/>\n&#8211; EQ bypass switch &#8211; true bypass<br \/>\n&#8211; Distortion less than 0.03% from 100 Hz and up.<br \/>\n&#8211; Third-harmonic distortion below 150 Hz<br \/>\n&#8211; Clipping at +28 dBu<br \/>\n&#8211; Current draw less than 100 milliamps<\/p>\n","protected":false},"featured_media":402,"comment_status":"open","ping_status":"closed","template":"","meta":{"_acf_changed":false},"product_brand":[25],"product_cat":[26],"product_tag":[],"class_list":["post-1310","product","type-product","status-publish","has-post-thumbnail","product_brand-wolff-audio","product_cat-wolff-audio","first","instock","taxable","shipping-taxable","product-type-simple"],"acf":[],"_links":{"self":[{"href":"https:\/\/smartaudiosolution.com\/en\/wp-json\/wp\/v2\/product\/1310","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/smartaudiosolution.com\/en\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/smartaudiosolution.com\/en\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/smartaudiosolution.com\/en\/wp-json\/wp\/v2\/comments?post=1310"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/smartaudiosolution.com\/en\/wp-json\/wp\/v2\/media\/402"}],"wp:attachment":[{"href":"https:\/\/smartaudiosolution.com\/en\/wp-json\/wp\/v2\/media?parent=1310"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/smartaudiosolution.com\/en\/wp-json\/wp\/v2\/product_brand?post=1310"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/smartaudiosolution.com\/en\/wp-json\/wp\/v2\/product_cat?post=1310"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/smartaudiosolution.com\/en\/wp-json\/wp\/v2\/product_tag?post=1310"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
