Quick Start Guide –
Installation Issues
Low-impedance microphones with standard cable wiring plug directly into the
microphone jacks without any modifications. Here’s how to handle some circumstances that
may affect your installation:
Replacing an old mixer
– If your installation has fixed microphone jacks with cables run as
part of the building (though walls, under floor, above ceiling), examine how these cables
terminate at your old mixer. If they have male XLR connectors, simply move them to your
new mixer. If they terminate as screw terminals, you’ll need to attach XLR plugs. We
recommend Neutrik NC3M connectors because they are easier to work with. If these are
not available, Switchcraft type A3M will do. Whether new or existing, connector wiring must
match the standard shown on page 2.
Mounting
–
The
mixer fits into a standard 19" rack, taking up one space. It needs no support
beyond the panel mounting screws. Be sure to place it where it’s easily accessible to the
operator. It makes little heat, but allow one rack space between the mixer and equipment
that does generate significant heat, such as power amplifiers.
Wireless mics
– Most wireless microphone receivers allow you to select a balanced,
microphone-level output. Choose this output and connect each wireless receiver to a
microphone input of the mixer. This way, the mixer handles each wireless mic as it does
other microphones, providing the gating and selectable compression features. Set any level
controls on the wireless receivers to match their level to that of your wired microphones.
Condenser microphones
– Condenser microphones feature excellent sound quality, but
require a power source to operate. Some use built-in batteries. Others expect to receive
power from the mixer’s microphone connection (this is called,
phantom power
). Your mixer
can provide phantom power at any or all microphone jacks. To select phantom power, see
Mixer Settings
, next page. Many condenser mics have a “hot” (loud) output – adjust your
mixer’s presets (see page 5) as needed.
Stereo Sources
– Use a “Y” adapter to combine the
Left
and
Right
channel of stereo sources
(such as CD players). Connect the resulting mono output to one of the two auxiliary inputs
at the mixer.
Multiple sources
– If you have more than two auxiliary (non-microphone) sources, we
recommend using an external selector switch to select among them. Different sources may
not perform properly if paralleled with “Y” adapters.
