The Mjr Mixer consumes approximately 50-60mA of current when no
microphones are being powered. This translates into a battery life of 5 to 10
hours. To remove the battery simply push down on the battery door and pull out
the battery.
Note: Never store your Mjr Mixer for extended periods of time with a battery
installed in the mixer.
causing corrosion of the mixer.
corrosion damage is not covered under the Mjr Mixer warranty.
CONSTRUCTION
A.
CHASSIS
The new Mjr Mixer chassis has been designed for harsh field use. The complete
chassis is formed from 0.070" aircraft aluminum. All punching is done on a
computer controlled "Strippet" rotary turret punch press for extreme accuracy. In
addition, through careful design, we have managed to keep the overall weight of
the Mjr Mixer to 1.5 lbs. (0.7Kg) total.
The mixers sheet metal is hand-formed using various press brake setups before
the stainless steel threaded inserts are pressed permanently into place. The
housing parts are then Chem Film TM plated for superior corrosion resistance
before being electro-statically coated with an epoxy powder coating.
powder coat paint is then baked on. Powder coating chosen for its durability and
environmental friendly characteristics.
All silk-screening is printed sub-surface (below) a hardface lexan tm overlay.
This process provides a silk-screened label that is virtually wear proof. The
lettering will not wear off as on other mixers.

ELECTRONIC TOPOLOGY
The new Mjr audio mixer was designed from a clean sheet of paper. It utilizes
completely new circuitry designs based upon the latest advances in semi
conductor technology.
reduced size and weight.
This new design uses modern semi-conductors from Maxim, Linear Technology
and National Semiconductor to name but a few. These operational amplifiers,
voltage regulators and precision voltage references feature low power
consumption, low noise and low distortion. The also feature ability to swing from
rail to rail resulting in an energy efficient design.
C.
ENVIRONMENTAL OPERATION
Your new Mjr Audio Mixer has been designed to operate under extreme field
conditions. The electronics have been designed to operate over a temperature
range of -4 to 158 degrees Fahrenheit (-20 to +70C) less the affects on batteries.
There is a possibility that the battery may leak
