1. Power Switch 2. Power Connection Push the 3-pin female side of the power adaptor securely into the connector on the rear of the mixer. Plug the other end into an AC outlet properly configured with the correct voltage as indicated on the AC adaptor. Only use the AC adapter that came with your mixer, or a factory-authorized power supply. 3. Mic Ins (Ch. 1–2) Phantom-powered, balanced Onyx mic preamps are on every VLZ4 mixer. These circuits are excellent at rejecting hum and noise.
402VLZ4 6. Instrument Switch (Ch. 1–2) “U” Like Unity Gain 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 impedance-matched 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 more. You will need a DI box if connecting instrument-level signals to the inputs of channel 3 and 4.
11. Level This control gives you up to 15 dB boost or cut 0 below 80 Hz. The circuit is flat (no boost or cut) at Low EQ the center position. This frequency range represents 0 the punch in bass drums, bass guitar, fat synth patches, and some really Low EQ with Low Cut serious male singers. Used in conjunction with the low cut [5] switch, you can boost the low EQ without injecting a ton of subsonic debris into the mix.
402VLZ4 14. Stereo Line Ins (Ch. 3–4) 17. Tape In These fully-balanced inputs are designed for stereo or mono, balanced or unbalanced signals. They can be used with just about any professional or semi-pro instrument, effect or CD player. Signals entering channel 3 are added to the left side of the main mix only. Signals entering channel 4 are added to the right. When connecting a mono device, always use the left (mono) input (ch. 3) and plug nothing into the right input (ch.
23. Power LED This global switch controls the phantom power supply for condenser microphones plugged into channel 1 and 2 mic [3] inputs. Press this in if your microphone requires phantom power. (The mixer can supply the microphone's power through the XLR connectors, using the same lines used for the audio.) Check with the microphone manufacturer if you are not sure. See the phantom power discussion on page 13 before using this switch. Press the switch in to engage phantom power to both mic inputs.
