Owner’s Manual
Patchbay Description
This is where you plug everything in: microphones,
line-level instruments and effects, headphones, and
the ultimate destination for your sound: a recorder, PA
system, etc.
Appendix B has details and drawings of the
connectors you can use with the 802VLZ4. Also see  
the channel strip description on page 16 for details
of the signal routing from the XLR and line inputs.
1. Mic Ins (Channels 1–3)
Phantom-powered, balanced Onyx mic preamps  
are on every VLZ4 mixer. These circuits are 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 802VLZ4’s
mic inputs will handle any kind of mic level you can toss
at them, without overloading. Be sure to perform the
getting started procedure on page 5.
Channel 3-4 is a hybrid design, with a mono mic input
in a stereo channel. The mono mic input is fed to both
sides of the stereo field.
Not every instrument is made to connect
directly to a mixer. Guitars commonly need  
a Direct Injection (DI) box to connect to  
the mixer's mic inputs. Channels 1 and 2 have  
an instrument switch [6] so you do not need a  
DI box, and can plug your guitar directly into the  
line inputs [2].
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 802VLZ4’s phantom power is globally controlled
by the phantom power [12] switch. (This means the
phantom power for the mic inputs of channels 1-3 is
turned on and off together.)
Never plug single-ended (unbalanced)
micro phones or instruments into the mic [1]
input jacks if the phantom power is on.
Do not plug instrument outputs into the mic
input jacks with phantom power on, unless
you know for certain it is safe to do so.
Do not use phantom power with ribbon
microphones.
