QUADRA
Receiver Operation
Battery Insertion
The receiver is powered by three AA batteries, either
alkaline, lithium, or rechargeable types. Do not use
"heavy duty" batteries from a drug store - they will not
last long in the M4 receiver.
Open the battery door by pressing on it while sliding it
downward. It should then flip open allowing full access
to the battery compartment. Carefully note the battery
orientation as indicated by the diagrams inside. The
outer two batteries are positive (+) facing in, while the
middle battery is positive (+) facing out.
Once the three batteries are in place, close the door
by swinging it shut then sliding it upwards while apply
ing slight pressure. It should snap shut and line up with
the case.
Powering the Unit ON and OFF
Press the power button once to turn on the unit. Check
to see that the LCD displays the single screen Power
Up Sequence showing the company logo, model num
ber and firmware revision.

Power Button
After the Power Up Sequence is displayed briefly, the
Main Window appears and the M4R is ready for opera
tion.
Note also that the BATT LED should be lit.
Green indicates good power. Red indicates your
batteries are 2/3 depleted. Flashing red indicates
that you should replace your batteries as soon as
possible.
To turn the receiver off, press and hold the power but
ton for three seconds. A countdown will be displayed
until the power is turned off.
Control Panel/Knobs
The four knobs on the top edge of the M4 receiver
(two are in a dual concentric arrangement and two are
separate) allow for a number of mixer configurations
by using the Chan. Setup in the LCD menu. The first
knob (the tall, skinny one) is usually set as a Master
Volume, while the other three can be set up differently
depending on the artist's needs and preferences. See
Selecting 2 Channel or 4 Channel Operation below
for details.
The headphone jack is a standard 1/8" stereo TRS (tip,
ring, sleeve) jack with standard headphone wiring (tip
is left, ring is right, sleeve is ground). The headphone
amp can deliver 200mW into a 32 Ohm load so it is
important to always start with the volume low before
plugging in your headphones or earbuds.
CAUTION: Hearing damage can result from
listening too loudly with this receiver!
