Setting Up and Using the
Concert Series System
this is unity gain. If you are using the HT7 transmitter or if you are using the CT7 transmitter with
a connected lavalier microphone or headset, speak or sing into the mic at a normal performance
level while slowly raising the volume of your amplifier/mixer until the desired level is reached. If
you are using the CT7 transmitter with a connected instrument, play the instrument at normal
performance level while slowly raising the volume of your amplifier/mixer until the desired level
is reached. If you are using a CT7 beltpack transmitter equipped with a lavalier microphone, note
that correct lavalier placement is critical to sound quality. We recommend that you place it as
shown in the illustration on the right—as close to your
mouth as possible but off to one side (to minimize nasal-
ity) and unobstructed by clothing. Bear in mind also that
omni microphones (mics which pick up signal from all
directions) are more prone to feedback problems than
unidirectional (cardioid or supercardioid) ones; in gen-
eral, you can avoid feedback by taking care not to use
any microphone directly in front of a PA speaker (if this
is unavoidable, try using an equalizer to attenuate those
high- or mid-range frequencies which are causing the
feedback “squealing”).
10. If you hear distortion at the desired volume level, first
check to see whether the yellow “Peak” LED on the CR77
is lit. If it is not, make sure that the gain structure of your
audio system is correctly set (consult the owners manual
of your mixer and/or amplifier for details). If the yellow
“Peak” LED is lit, do the following:
• If you are using a HT7 transmitter, use the supplied plastic screwdriver to turn its
Microphone Input Level control (trimpot) slowly counterclockwise (towards the “Min” posi-
tion) until the distortion disappears.
• If you are using a CT7 transmitter with connected lavalier microphone or headset, its Audio
Input Level control has been factory preset to provide optimum level for the particular
lavalier or headset model being used and so no adjustment should be necessary. Any dis-
tortion present should therefore simply be a matter of the microphone being too close to
the mouth; try moving it further away. If this does not solve the problem, use the supplied
plastic screwdriver to turn the Audio Input Level control (trimpot) on the CT7 slowly coun-
terclockwise until the distortion disappears.
• If you are using a CT7 transmitter with an instrument such as electric guitar or bass, lower
the output level of the instrument until the distortion disappears. Alternatively, you can use
the supplied plastic screwdriver to turn the Level control (trimpot) on the CT7 slowly coun-
terclockwise until the distortion disappears.
Note that, following this setup procedure, you can always lower the Volume knob of the CR77 in
order to attenuate the output signal if necessary.
