Mobile Max
The MobileMax generates two distinctly different types of echo, 9 different E.T.S. (Roger
Beep) sounds, and can record and play back a six second message . The MobileMax is a
true DSP (digital signal processor) system using 14-bit analog to digital and digital to analog
converters.

Location and Mounting

Choose a good location for your MobileMax which is convenient for the operation of the front
panel controls. It is suggested that you locate the unit near the CB. It is acceptable to mount
the MobileMax on top of your CB. Connecting the metal chassis of MobileMax to the chassis
of your CB or vehicle may increase the possibility of RF feedback (Squeal) problems. If
possible, mount the MobileMax to a non-metal panel or use double-sided foam tape.

Initial Setup

Connect the red wire of power cable (14) to a 12 Volt source and connect the black wire of
power cable (14) to ground. The MobileMax is designed for negative ground vehicles. If you
have a positive ground vehicle, call the factory for special instructions. Plug your favorite
microphone into Mic In (1). Plug mic cable (10) from the rear of the MobileMax into your CB
radio. Now with On/Off switch (8) in the OUT position, your system will work as usual.

Connections

pin 1 - common, shield
pin 2 - audio
pin 3 - transmit
pin 4 - receive
Set Input & Output Level
Turn the Effects Gain (5) full counter clockwise. Now push the On/Off button (8) in, key your
microphone and talk. Adjust Mic Gain (7) while talking. You will see the bar graph display (4)
light as you talk. Adjust the Mic Gain (7) so that the right most red display of the bar graph
occasionally flashes. Setting the Mic Gain (7) louder than this will cause the MobleMax to
distort. Setting the Mic Gain lower than this will result in less than optimum performance.
When the Mic Gain (7) is fully clockwise, the MobileMax will add 20dB of gain (amplification)
between your microphone and your CB radio. If this makes your microphone pick up too
much background noise or causes your CB radio to squeal, turn down your CB radio's
microphone gain (sometimes called modulation or dynamic). You will still get full modulation
out of your CB radio, since the MobileMax has already compensated for the gain.
Effects
Turn the Effects Gain (5) and the Effects Delay (6) to the 12 o'clock position. Turning the
Effects Delay (6) clockwise from the 12 o'clock position will increase the delay time of Slap
