Introduction; Instant Setup; Making Connections - Phonic MU 502 User Manual

INTRODUCTION

Thank you for choosing one of Phonic's many quality compact
mixers. The MU series of Mixers – designed by the ingenious
en¬gineers that have created a variety of mixers fantastic in
style and performance in the past – displays similar proficiency
that previous Phonic products have shown; with more than a few
refinements, of course. The MU series features full gain ranges,
amazingly low distortion levels, +22 dBu line signal handling, and
incredibly wide dynamic ranges, just showing the dominance these
small machines will have in the studio or live venues.
We know how eager you are to get started – wanting to get the
mixer out and hook it all up is probably your number one priority
right now – but before you do, we strongly urge you to take a look
through this manual. Inside, you will find important facts and figures
on the set up, use and applications of your brand new mixer. If
you do happen to be one of the many people who flatly refuse
to read user manuals, then we just urge you to at least glance at
the Instant Setup section. After glancing at or reading through the
manual (we applaud you if you do read the entire manual), please
store it in a place that is easy for you to find, because chances are
there's something you missed the first time around.

INSTANT SETUP

Getting Started
1. Ensure all power is turned off on your mixer. To totally ensure
this, the AC cable should not be connected to the unit.
2. All faders and level controls should be set at the lowest level and
all channels switched off to ensure no sound is inadvertently
sent through the outputs when the device is switched on. All
levels can be altered to acceptable degrees after the device
is turned on.
3. Plug all necessary instruments and equipment into the device's
various inputs as required. This may include line signal devices,
such as bass and drum machines, as well as microphones
and/or guitars, keyboards, etc.
4. Plug any necessary equipment into the device's various out-
puts. This could include amplifiers and speakers, monitors,
signal processors, and/or recording devices.
5. Plug the supplied AC power supply into the inlet on the rear of
the device and then into a power outlet of a suitable voltage.
6. Turn the power switch on and follow the channel setup instruc-
tions to get the most out of your equipment.
CHANNEL SETUP
1. To ensure the correct audio level of the input channel is se-
lected, each of the level input controls of the Mixer should be
turned counterclockwise as far as they will turn (which should
be the -∞ mark).
2. No input other than the one being set should have any device
plugged in. This will ensure the purest signal is used when
setting channels.
3. Ensure the channel has a signal sent to it similar to the signal
that will be sent when in common use. For example, if the
channel is using a microphone, then you should speak or
sing at the same level the performer normally would during a
performance; if a guitar is plugged into the channel, then the
guitar should also be strummed as it normally would be (and
so on). This ensures levels are completely accurate and avoids
having to reset them later.
4. Set the gain so the level meter indicates the audio level is
around 0 dB.
5. This channel is now ready to be used; you can stop making
the audio signal.
6. You can repeat the same process for other channels. Or not,
it's your call.

MAKING CONNECTIONS

Inputs and Outputs
1. XLR Microphone Jacks
These jacks accept typical 3-pin XLR inputs
for balanced and unbalanced signals. They
can be used in conjunction with microphones
– such as professional condenser, dynamic
or ribbon microphones - with standard XLR
male connectors, and feature low noise
preamplifiers, serving for crystal clear sound
replication. Each of the MU series mixers
features two standard XLR microphone inputs
for your convenience.
NB. When these inputs are used with condenser microphones, the Phantom
Power should be activated. However, when Phantom Power button is
engaged, single ended (unbalanced) microphones and instruments should
not be used on the Mic inputs.
2. Line Inputs
This input accepts typical 1/4" TRS or TS inputs, for balanced or
unbalanced signals. There are various numbers of these inputs
depending which mixer you are using. They can be used in
conjunction with various line level devices, such as keyboards,
drum machines, electric guitars, and a variety of other electric
instruments.
3. INS (Insert) (MU502 only)
Located below the channel 1's XLR
microphone input, the primary use for this
TRS phone jack is for the addition of external
devices, such as dynamic processors or
equalizers, to the mono input channel. This
will require a Y cord that can send and receive
signals of the mixer to and from an external
processor. The MU802 and MU1002X mixers
do not feature these jacks; however can have
external processors running parallel through
the various outputs and inputs.
4. Stereo Channels
Each of the MU mixers features a few stereo channels, thrown in
for maximum flexibility. Each of these stereo channels features
two 1/4" phone jacks, for the addition of various line level input
devices, such as electronic keyboards, guitars and external signal
processors or mixers. On the MU502, the first stereo channel
(mic 2-3) features both a 3-pin XLR microphone input and two
1/4" phone jacks, therefore can be used as either a monaural
microphone or line input channel or a stereo line input channel.
These stereo channels can also be used as mono channels, where
the signal from any 1/4" phone jack plugged into the left stereo
input will cause the signal to duplicate to the right input also. This
does not work in reverse, however.
