TK Audio TK-lizer Mastering EQ with M/S Function


"Fine tuning EQ - all the way from the lows to the highs"

Manufacturer Description:


Our new TK-lizer is a Baxandall type of EQ, high and low bands are selectable between shelving or bell, very useful for fine tuning of your low’s, mid’s and high’s. 

The EQ also has a built in M/S function which lets you process the mid and side signals separately.

You can also affect the stereo width of your music by using the level controls in M/S mode.

The three bands are based on the legendary Baxandall circuit from the 50’s.

We like to thank Wayne Kirkwood at KA Electronics for letting us use his genius M/S circuit!!
