"This listing is for a pair of gold-trimmed Urei 565T Filter Sets in a black Tolex case (or without). These look incredible. The seller we bought them from wrote:

The 565T offers precise notching and peaking of very narrow frequency bands. The major application is to remove unwanted noises from recordings. Used extensively by the movie industry. It can also be used to create flanging, phasing and other unusual effects.

The 565T has an output transformer that can send a balanced signal to a 600 ohm load. The input level can be switched up 20db and the input impedence can be set between 600 and 10K ohms. This item came out of temperature controled editing suite. The suite had preventative maintenance done quarterly.

Having these will make you feel better in your studio, and feel better about your studio.

You don’t need to worry about the rear connections. You don’t need to make pigtails. You have an in and an out right on the front of the unit, and it takes balanced TRS or unbalanced TS.

What will you use it for? A notch filter, feedback murderer? Lowpass filtration on the 2bus for performative transitions? Nasal peaks? Dub stuff? Purist period-correct cinematic effects? Reductive sonic biopsies, additive implants?

MOJO MOJO."

Urei 565T Little Dipper Demo.m4v

YouTube via FlakeStick | February 02, 2010 | - new video below

"This is a quick demo of the Little Dipper audio filter. Recording straight to MacBook audio in through an Alesis Multimix 8 mixer. No other eq or effects were added. The synthesizer is a Roland Jupiter 6 (off camera) which already has a robust filter of its own. The 565T has a very gentle high and low pass curve while the notch filters are in the on position. It's the dual notch/peak filters that can really transform the sound going in. Exciting phaser effects start to happen when the notch frequencies approach each other. You can read articles online how it was designed for filtering out very isolated frequencies when no other piece of kit will do....but there's nothing like transforming your favorite instruments into something different. Definitely share any tips and tricks with me as I would love to try them "
