New, unused, "Fukumiya Electronics" 4-band parametric equalizer for sale. This product was designed and manufactured by our analog engineer, who was involved in the maintenance of mixing consoles and peripheral equipment, as well as the design and manufacture of custom-made equipment in recording studios in Tokyo in the late 80s. This is a unique 4-band parametric equalizer, and despite its "effector size" enclosure, it incorporates four bands thanks to the appropriate component placement by a qualified printed circuit board designer. While compact, it boasts high sound quality, allowing players to create detailed sounds comparable to mastering equipment right at their fingertips. We have also paid close attention to the selection of components, using high-quality parts such as WIMA capacitors and DALE audio metal film resistors for the main signal path. Oxygen-free copper shielded wire is used for the input section. Variable Range (Frequency display indicates the variable range of the center frequency) LOW GAIN: ±15 Q: 1/12～3oct Freq: 65～550Hz MID GAIN: ±15 Q: 1/12～3oct Freq: 450～2KHz MID-HI GAIN: ±15 Q: 1/12～3oct Freq: 1.2K～5.5KHz HI GAIN: ±15 Q: 1/12～3oct Freq: 4.2K～16KHz Overall frequency response: 30Hz～20KHz (-20db) All 4 bands are peaking type. Power (ON when the IN plug is inserted) 006P 9V battery and AC adapter (DC jack center negative) Protection circuit for center positive jack use (power will not turn on) DC input: DC9V～DC12V AC adapter or 9V battery (batteries not included) The battery in the photo is for size comparison. The device has a series power supply (rail splitter circuit) without a boost circuit. Bypass switching method: Non-contact switching using audio FETs Dimensions: W85XD120XH35(mm) Case material: Aluminum die-cast Weight: 428g (without battery) Not sold in the market. Only sold for the units made by hand. Due to rising component costs, this price is set. We apologize for any inconvenience, and thank you for your understanding.
