[. . . ] MIC INPUTS (Ch. 1­2) We use phantom-powered, balanced microphone inputs just like the big studio mega-consoles, for exactly the same reason: This kind of circuit is excellent at rejecting hum and noise. You can plug in almost any kind of mic that has a standard XLR male mic connector. Professional ribbon, dynamic, and condenser mics will all sound excellent through these inputs. The 402-VLZ3's mic inputs will handle any kind of mic level you can toss at them, without overloading. 5. LOW CUT (Ch. 1­2) Each low-cut switch, often referred to as a high-pass filter (all depends on how you look at it), cuts bass frequencies below 100 Hz at a rate of 18 dB per octave. We recommend that you use low-cut on every microphone application except kick drum, bass guitar, or bassy synth patches. These aside, there isn't much down there that you want to hear, and filtering it out makes the low stuff you do want much more crisp and tasty. Not only that, but low-cut can help reduce the possibility of feedback in live situations, and it helps to conserve amplifier power. Another way to consider low-cut's function is that it actually adds flexibility during live performances. With the addition of low-cut, you can safely use low equalization on vocals. Many times, bass shelving EQ can really benefit voices. Trouble is, adding low EQ also boosts stage rumble, mic handling clunks and breath pops. Applying low-cut removes all those problems, so you can add low EQ without losing a woofer. PHANTOM POWER Most modern professional condenser mics are equipped for phantom power, which lets the mixer send low-current DC voltage to the mic's electronics through the same wires that carry audio. (Semi-pro condenser mics often have batteries to accomplish the same thing. ) "Phantom" owes its name to an ability to be "unseen" by dynamic mics (Shure SM57/SM58, for instance), which don't need external power and aren't affected by it anyway. The phantom power for both channels 1 and 2 is turned on and off together using the phantom [20] switch. Owner's Manual 13 402-VLZ3 6. INSTRUMENT SWITCH (Ch. 1­2) When this switch is pressed in, channel 1 or 2's line input can accept direct instrument-level signals from guitars or other instruments. They will be impedancematched to the line input, without the need for a DI box. When this switch is out, you can connect line-level sources such as CD players, MP3 players, keyboards, drum machines, and tape players. You will need a DI box if connecting instrument-level signals to the inputs of channel 3 and 4. Direct-In (DI) boxes are commonly available from most music stores. They provide signal and impedance matching for the direct connection of guitars and other instruments to amplifiers and mixers. They convert unbalanced instrument-level signals to a balanced mic-level output.
