Operation - Transmitter unit
The ½ rack transmitter unit has a large LCD window with 3 buttons alongside it. Press and hold the
Power button (1) on the left of the unit will power up the transmitter and the LCD display will be lit.
Any audio signal played into the transmitter unit will be indicated by L + R bar meters on the left of
the LCD display. The level of the input is governed by the INPUT LEVEL rotary control (3) and if
necessary, a PAD switch on the rear panel can apply a -12dB cut to high level input signals.
Pressing the “SET” button (2) enters the settings mode and repeated pressing of the SET button
steps through the different settings available on the transmitter.
Pressing the SET button once will cause the upper left character
named “GROUP” in the display to flash. The IEM16 has only 1 group
of frequencies, so this parameter will not need to be changed.
Pressing the SET button twice steps on to the CHANNEL setting and
using the UP/DOWN buttons (2) will change the channel that the
IEM16 is transmitting on to one of 16 available UHF frequencies.
Pressing the SET button 3 times steps over to the STEREO/MONO
setting, which can be toggled between mono or stereo output using
the UP/DOWN buttons. Mono is especially useful when using a single
earpiece instead of 2.
Pressing SET 4 times steps on to the power setting labeled “POW”.
The UP/DOWN buttons can select between H (high) or L (low) power
for the transmitter carrier signal. Normally, this is set to H (high)
unless the carrier signal is causing interference with other nearby
equipment, in which case, it may be better to set it to L (low).
Pressing the SET button 5 times will step through to the LOC mode.
Pressing the UP button selects “LOC on” and then pressing the SET
button will indicate “LOC on” and no other settings can be changed.
To unlock the panel, press the DOWN button to select “LOC off”
Whilst in lock mode, the POWER button will not function. When the lock function is off, pressing and
holding the POWER button will power down the transmitter unit.
The transmitter unit has a 6.3mm stereo output for wired headphones (4), which can be used in
addition to the UHF bodypack receiver(s). This output has its own dedicated output volume control
on the front panel (5). This output may also be used to check the quality of the monitor feed before
switching on any bodypack receivers.
