Guided Tour - AH7 Transmitter
2
1. Power switch - Press and hold this switch to power on and off the AH7 transmitter (to
conserve battery power, be sure to turn the AH7 off when not in use). To eliminate the
possibility of an audible pop, mute the audio signal at your external mixer or amplifier
before turning the AH7 power on or off.
2. Power / Battery LED - This LED flashes once when the AH7 is first turned on and lights
steadily red when there is less than 2 hours of battery power remaining, indicating that
the battery needs to be changed.
3. Battery compartment - Insert a standard AAA alkaline battery here, being sure to observe
the plus and minus polarity markings shown. We recommend the Duracell 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
AH7 and will void your warranty.
4. Antenna - This permanently attached flexible antenna should be fully extended during
normal operations.
5. Input Gain Control - This control adjusts the transmitter input sensitivity (gain).
For optimal performance, using the included screwdriver, set the input Gain
control to where you see the CR77 AUDIO METER level at 0dB during normal
performance and reaching +3dB under high levels. If your level is at +6dB, the
audio signal will be distorted and the input Gain control should be turned down.
