INTRODUCTION
Thank you for your purchase of the MX54s ProMix Plus. This unit is
designed and manufactured to mix three microphones together and send
their combined signals out stereo transformer-balanced XLR outputs. The
individually switchable phantom power and low-cut switches provide he
final touches which make the MX54s a valuable tool for any sound
reinforcement, musical, recording, or install application.
INSPECTION
1. Unpack and Inspect the MX54s package
Your MX54s was carefully packed at the factory in a protective carton.
Nonetheless, be sure to examine the unit and the carton for any signs of
damage that may have occurred during shipping. If obvious physical
damage is noticed, contact the carrier immediately to make a damage
claim. We suggest saving the shipping carton and packing materials for
safely transporting the unit in the future.

DESCRIPTION
REAR PANEL
Mic Input: 1 - 3: XLR balanced inputs for connection to any standard
dynamic or condenser microphone.
Right and Left Outputs: Transformer balanced XLR output jacks for
connection to the next device in the signal chain such as a signal proces-
sor or amplifier.
Right and Left Trim controls: Screwdriver adjustable controls to vary the
level of each output. NOTE: These controls are set at mic level from the
factory. Turning them
counter-clockwise
increases the output level. These
controls do not effect the Aux/Headphone Output.
FRONT PANEL
Mic Level 1 - 3: These controls adjust the level of the corresponding Mic
channel. The level varies from -infinity (off) to +60 dB of gain (typical).
PAN 1 - 3: Adjusts the relative right/left level of each channel.
Phone/Aux: 1/4" TRS jack which may be connected to a pair of head-
phones for personal monitoring, or to an unbalanced input of a signal
processor or amplifier.
Power LED: Indicates the MX54s is on.
Clip LED: Indicates that clipping is about to occur or occurring in the
MX54s circuitry. This LED begins to light 3dB below actual circuit clipping.
Power Switch: Applies power to the MX54s.
Located on the right side of the unit is the +12 VDC power jack for connec-
tion to an optional +12 VDC (outside of the ring is positive) external power
supply. We recommend the Rolls PS27.
Locatd on the left side of the unit is the battery
compartment which houses two 9-Volt (alkaline
preferred) batteries.
Also on the left side are the Phantom Power and
Low-Cut switches.
As shown here, under each number is a P indicating
Phantom Power, and an L which indicates Low-Cut.
When the P switch is DOWN, the phantom power is ON, when it is UP, the
phantom power is OFF.When the L switch is UP, the low-cut is ON, when it
is DOWN, the low-cut is OFF.
