SuperBroom Plus TA – Operating Manual

In DSP mode, SuperBroom automatically sets the power 
level relative to the maximum TX level set at start-up in 
the ‘Set Tx Power‘ menu.  The power control allows  the 
transmitter power to be reduced from the maximum set 
during startup down to level 2.

Caution      Always reduce the volume control to its minimum value 

before connecting the headphones.  Set the Squelch control 
to its minimum value so that the audio level can be gauged 
when setting the volume control.

The headphone socket above the Volume control is suitable 
for a 1/4 inch ‘Stereo’ type jack plug.  The audio amplifi er is 
capable of driving a range of headphone types.

A 16-segment bar graph mimics the signal strength display 
for the signal source selected.

COMPARE 

-  displays the difference between the signals 

from the two receivers.  If the third harmonic is stronger than 
the second there is no output.

2nd 

-   displays the signal strength of the second harmonic.

3rd 

-   display the signal strength of the third harmonic.
