Setting The Interference Suppression; Setting The Mixing Ratio Of The Microphone Signals - IMG STAGELINE TXS-626 Manual De Instrucciones

c) To set the channel number, press the but-
ton SET repeatedly until the numerals for
CHANNEL start flashing.
d) Set the channel number with the button
or . Once the numerals stop flashing, the
channel setting has been stored.
3) If the antenna symbol appears on the left or
on the right of the display while the transmit-
ter (wireless microphone / pocket transmitter)
is still switched off, interfering signals or sig-
nals from another wireless system are re -
ceived. In this case, set a different channel.
4) Switch on the transmitter and point the IR
sensor of the transmitter towards the IR win-
dow (1) on the receiving part (see instruction
manual of the transmitter, if required). The
distance must not exceed 1.5 m. Make sure
that there are no obstacles between the sen-
sor and the IR window.
Briefly press the button ACT (2). The dis-
play backlight of the transmitter is activated.
Thus, the transmitter and the receiving part
are set to the same channel.
5) After the receiving part and the transmitter
have been set to the same transmission
channel, the antenna symbol
the left or on the right of the display of the
receiving part (symbol on the left = left
antenna receives the most powerful signal). If
no antenna symbol appears, please check:
a Are the batteries of the transmitter ex -
hausted?
b Is the reception disturbed by metal objects
in the transmission path?
c Is it possible to improve the reception when
you turn the receiving antennas?
d Is the distance between the transmitter and
the receiver too long?
e Has the interference suppression been set
too high with the control SQUELCH (13)?

4.3 Setting the mixing ratio of the
microphone signals
The mixed signal of the two receiving parts is
present at the jack SUM OUT (11). To set the
mixing ratio of the individual signals, it is possi-
ble to change the volume of the two microphone
signals separately. For this purpose, first set the
signal to be heard at the highest volume in order
to match the output level of the jack SUM OUT to
the input of the subsequent unit at the same
time. Then add the second microphone signal.
1) Switch on the audio unit following the receiver
or advance the corresponding control of the
mixer.
2) Press the button SET (5) three times so that
the numerals for VOL start flashing.
3) Speak / sing into the microphone. While the
numerals keep flashing (a few seconds after
pressing the button SET, or
ume with the button or
00 – 63].
Note: If the numerals stop flashing before you have
set the volume, press the button SET three times
again.
4) Once the numerals stop flashing, the setting
has been stored.

4.4 Setting the interference suppression

With the control SQUELCH (13), adjust the
threshold value for response of the interference
suppression. The interference suppression will
mute the receiving part during pauses in speech
or vocals when interfering signals are received
and their levels are below the threshold value
adjusted. A high threshold value, however, will
also reduce the range of the microphone system:
If the power of the radio signal falls below the
threshold value adjusted, the receiving part is
also muted. Therefore, adjust a high threshold
value (turn the control towards MIN) when the
reception is good and a low value (turn the con-
trol towards MAX) when the distance between
the transmitter and the receiver is long.
