Audix AP41 BP, User Manual

17

Group/Channel˝ can also be controlled manually from the menu. Activate the menu (see 
previous page). When GROUP˝ appears, press SET. The current Group˝ will be displayed. 
Press either the UP or DOWN button to scroll to another Group˝ and then press SET. The 
new Group˝ will be saved and will appear on left side of the display.  

Hint: The word CHANNEL˝ will appear to the upper right of the number. This means the 
display is in Channel mode. The menu displays Group/Channel˝ as the default. Press the SET 
button (quickly) and the Frequency˝ will appear on the screen. After 5 seconds it will default 
back to Group/Channel˝. To set Frequency˝ as the default display see Display˝ (pg 18).

To change the channel, go to CHAN˝ in the menu (it’s next in line after GROUP˝) and press 
SET. The current channel will be displayed. Scroll through the channels and select the one 
you want, then press SET. The same applies if Frequency˝ has been selected as the default.

GROUP/CHANNEL (AP42 ONLY)

 
Please note that the AP42 dual receiver system is designed for both receivers to be used 
in the same Group. Whenever the Scan-Sync function is run, the AP42 system will choose 
the optimum Group and place both receivers in the same Group. We suggest always using 
the Scan-Sync function to choose new frequencies. When manually changing the Group, 
please note that the Group will change accordingly on both receivers.    

FOR BEST RESULTS, DO NOT CHANGE FREQUENCIES DURING A PERFORMANCE.   

LEVEL 

This setting allows for additional gain control over the receiver. The factory setting is +6, a 
good gain setting for Audix dynamic microphones. The VX5 condenser microphone has 
much more output than a dynamic mic and is better suited in the -6 or -9 range.
   
Hint: The key to a good sound with the least amount of noise and distortion is finding  
the balance between the mixer, the receiver and the capsule gain. A soft singer, for  
example, will require more gain on the mixer and receiver, which could potentially add 
some noise into the system. Fine tuning the receiver setting can be helpful in these cases. 
A loud singer, on the other hand, will require less gain and possibly a gain reduction on 
the transmitter itself for control over distortion.  

SQUELCH

Squelch˝ is an important design facet of a wireless circuit. It mutes or suppresses noise 
from the receiver in the absence of a desired signal. Typically, the lower the squelch, the 
less signal it takes to activate the receiver. The higher or tighter the squelch, the higher
