After over six decades, Heritage Audio has revived one of the most desired program equalizers of all time with the PEQ-2, a passive EQ rack unit with powerful tone shaping controls and a versatility that goes beyond even the legendary Pultec. 26 frequency options provide wide ranging possibilities when processing signals, including the ability to boost and cut at different frequencies for unique or interesting transformations. Adjustable HF boost bandwidth (sharp or broad) and a frequency selection range from 20 Hz to 20 kHz makes the PEQ-2 an inviting yet powerful processor that allows for quick or granular adjustments of the frequencies in your material in any recording, mixing, or mastering application. The PEQ-2 includes the HA-PSU04 and an AC cord, so you can start processing audio right away.
