Guided Tour - HT7

1:  Audio on-off switch

 - When set to the “on” position, 

audio signal is transmitted.  When set to the “off” 

position, the audio signal is muted.  Because the carrier 

signal remains during muting, no “pop” or “thud” will be 

heard.  Note that turning this off does not turn off the 

transmitter power—it is simply a way to temporarily 

mute the transmission of audio signal.  If you don’t 

plan on using the transmitter for extended periods, 

turn off the transmitter power by using the power ON-

OFF switch (see #3 below).

2:  Battery level meter

 - This set of three  multicolored 

LEDs indicates relative battery power, indicating 

whether the installed battery is at low (red), mid 

(yellow) or high (green) strength. One of these will 

light whenever the HT7 is powered on (see #3 below).  

When the red “low” indicator lights, RF performance is 

degraded and the battery needs to be replaced.

3:  Power ON-OFF switch*

 - Use this to turn the HT7 

on or off (to conserve battery power, be sure to leave it 

off when not in use).

4:  Microphone Input Level control (trim-pot)

 - This 

input sensitivity control has been factory preset to 

provide optimum level for the particular microphone 

capsule provided with your Concert 277 system and so 

we recommend that this not be adjusted manually. If 

necessary, however, you can use the supplied plastic screwdriver to raise or lower the input level.  

See the “Setting Up and Using the Concert Series System” section on page 6 in this manual for 

more information.

5:  Battery holder

 - Insert a standard 9-volt alkaline battery here, being sure to observe the 

plus and minus polarity markings shown.  We recommend the Duracell MN 1604 type battery.  

Although rechargeable  Ni-Cad batteries can be used, they do not supply adequate current for 

more than four hours.  

WARNING:

  Do not insert the battery backwards; doing so can cause 

severe damage to the HT7 and will void your warranty.

* Be sure to mute the audio signal at your external mixer or amplifier before turning transmitter 

power on or off, or an audible pop may result.
