Master Section
Master Control
The Master Control is used to set the overall level of the Yorkville EXM Mobile Tower.
Note: When two systems are linked together, the Master Control only affects the level of the unit
on which it is located.
Sub Control
The Sub Control is used to set the relative level of the subwoofer to the satellite speakers. Typi-
cally, this control should be set to around noon. If you are using microphones and acoustic guitars
and do not need much bass, turn the Sub level down to help prevent low frequency feedback.
Modes
The EXM Mobile Tower contains 2 system modes, which alter the unit’s EQ and dynamics to best
suit its intended use and application. For music playback, Club mode should be selected. For live
performance, live mode should be selected.
Main Input / Main
Output Section
In situations where additional bass or
input channels are needed, the Link
jacks can be used to connect multiple
EXM systems and/or a subwoofer.
Main Input and Main
Output Jacks
The Main Input and Main Output
jacks are in parallel, we have pro-
vided both male and female XLR
connectors to help make it more
convenient to ‘link’ EXM enclosures
together. To use the Link feature,
insert a standard XLR patch cable
between cabinets.
USB Power Output
A USB power port is included on the
EXM Mobile Tower, this port provides
a fixed output of 5V with up to
500mA of current, and is intended
for power delivery only. Typically,
this port would be used to charge
another small battery-powered de-
vice such as a cell phone.
Battery Status Indicators
The EXM Mobile Tower has a series of four green LEDs to indicate the approximate charge level. The up-
per green LED is illuminated if there is greater than 75% charge in the battery. The red LED only will in-
dicate that the battery is critically low (approximately 10% remaining) and needs immediate charging.
Note: The indicators will be active only when the power switch is turned on.
Low-Power “Sleep” State
The EXM Mobile Tower features a special “sleep” mode which reduces energy consumption when
the system is not in use which preserves battery life. The unit will enter sleep mode after approxi-
mately 10 minutes of inactivity.
Note: This mode is disabled whenever AC is connected to the unit. To ensure that the sleep state
doesn’t interfere with normal operation, the output level should be controlled with the Master con-
trol, especially where quiet playback is desired.
