Selecting
CHANNEL CHANGE
- S3500 & S4000 only:
Initially the current channel’s frequency is displayed. Press or hold down the
∆∆
button to scroll through the available channels in the current bank. When you
reach the required new frequency, press the
SELECT
button to choose it. The receiver will immediately switch to the new frequency, and the normal display
will return.
The exact selection of channels available in each bank will depend on how the transmitter has been programmed in the factory. It can contain up to 32
unique channels, which can be arranged in up to 4 banks, but your transmitter will not necessarily contain this many channels or banks.

Selecting
BANK CHANGE
- S3500 & S4000 only:
The current bank is displayed. Pressing the
∆∆
button will change to the next bank. Pressing the
SELECT
button will choose the bank being displayed to
become the current bank, and will then return you to the normal display. Note that doing this will reset the current frequency to the first in the new bank, so it
will probably be necessary to change the frequency after changing the bank.
As already mentioned above, the exact selection of banks available will depend on how the transmitter has been programmed in the factory. There can be
up to 4 banks, but if there is only 1, this option will not be functional
.

Selecting
PROGRAM INFO
- S3500 & S4000 only:
This will display information on the program in the receiver. To clear this information, press the
SELECT
button to return to the normal display.
•
Selecting
MUTE LEVEL
- S3500 & S4000 only:
This will show the setting of the rear
MUTE
control, and will change to reflect adjustments made to this control. Press the
SELECT
button to clear this
information. If the receiver is muted, this will return you to the normal display, otherwise you will see the RF bar chart. In this case, pressing either button will
then return you to the normal display. See the section below for details of how to set the mute level for optimum performance. When adjusting the mute level,
the transmitter should be switched off.
•
Selecting
NAME INPUT
- S3500 & S4000 only:
This allows you to enter a user name which can be displayed in the normal display. The user name can be up to eight characters long. In order to change the
name from this option, the name is displayed with a cursor under the first character. Pressing or holding down the
∆∆
button will scroll through the available
characters at the cursor position. Pressing the
SELECT
button will move the cursor along one position. Pressing the
SELECT
button on the last character in
the name will return you to the normal display. It will be necessary to change each of the eight character locations in turn. If you miss the character you want,
simply scroll round until it comes back again.
•
Selecting
DISPLAY NAME?
- S3500 & S4000 only:
This allows you to configure whether or not the user name is displayed in the normal display. Pressing the
∆∆
button will toggle this setting on and off. Pressing
the
SELECT
button will return you to the normal display.

Setting the Mute Level:
The mute level can be adjusted if the receiver is picking up unwanted radio signals (due to intermodulation and other FM signals). In order to make this
adjustment, the transmitter must be switched off. The receiver should now be muted. If it is not, then slowly adjust the
MUTE LEVEL
control until all unwanted
signals are muted. Due to the receiver’s noise searching circuitry, no noise should be present at the audio output regardless of the mute setting. Once you
have done this, switch the transmitter back on and check its operation. If desired, the mute level can be viewed in a numerical format on the S3500 and S4000
by selecting the appropriate menu option as described above. Setting the mute level too high will reduce the range of your system. S3500 and S4000 receivers
indicate on their display that they are muted. S4000F systems are muted when all of the LEDs except the power LED are extinguished.

Optimising the Gain of your system:
In order to achieve the best possible audio performance from your radio system, it is worth spending a few minutes setting the optimum gain level.
First adjust the gain of your transmitter, as described in the appropriate section. The optimum setting for this will be found by first adjusting the transmitter
gain so that the audio peak LED on the receiver just illuminates for the loudest signal that is likely to be transmitted. The gain should then be decreased
slightly so that the peak LED never lights in normal operation. If the peak LED is lit, then distortion is likely. The optimum setting will vary according to who is
using the microphone and how close the microphone is placed to the mouth. For guitar systems, different instruments will require a different setting. On the
S4000F, the peak LED is the only indicator available for setting the transmitter gain. On the S3500 & S4000, the VU meter is also available as a guide.
Once the transmitter gain is optimised, it is necessary to match the receiver’s output gain to your mixing desk or PA system. If using the jack output, adjust the
GAIN
control to give the optimum level for your system. Adjusting this too high may cause distortion. If you are using the XLR output (S3500 and S4000 only)
then you must adjust the gain on your mixer or PA system as the output level is fixed.
