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.
