I can't give these little devices enough praise! They are so easy to use and bring a new dimension to your sound. Ok, so most modern mixes have cuts and kills by default, but they are not a patch on one of these, not even on a Pioneer DJM600! These little gems use near analogue circuitry to give you a warm rich softer sound, rather than the cheaper mixer embedded kills you find these days.
If you can find some of these, buy them, they really are worth it. I had to get mine off ebay in the US, but despite coming with 110v power supplies and the hastle it took to find a suitable UK one to replace them, it was worth every penny.
This is what you get for your money:
“The Electrix EQ Killer ($299) is a Kill Box that lets DJs and producers EQ an element without investing in expensive equipment. Built like a tank, the unit comes encased in a rugged aluminium housing that will absorb a lot of abuse. With the included joiner plate, you can connect two Electrix mods devices in a 19-inch rack. The EQ Killer can also rest on a flat surface. The front panel is tilted upward, making the controls easier to read.
Kill the Band The front panel is divided into three sections: Low, Mid, and High. Each section has a Momentary switch, a Band Kill switch, and level control knobs. The level knobs dial up the amount of gain or attenuation for their respective frequency bands, offering up to 6 dB of gain per band. Unity gain is achieved when the level knob is set at 12 o'clock. Between the Low, Mid, and High level knobs are the Low X-Over and High X-Over sweep controls. The Low X-Over sets the point where the Low band ends and the Mid band starts. The High X-Over adjusts where the Mid band ends and the High band starts.
The back panel has three input/output sections. Inputs 1 and 2 have standard RCA stereo connectors. There's also a switch to select between line level and turntable input levels, and grounding posts for turntables. The third section's Send/Return loop lets you apply external effects to the killed band. At the front of the unit's bottom right-hand corner is an input selection switch for toggling between turntables or line-level devices. The button will act as a bypass switch if there's only one device connected to EQ Killer”.
