Step 2
Placing the transmitter
Ideally, the transmitter should be placed at an elevation such that there
are no obstacles between the transmitter and wireless receivers or
amplifiers (line of sight) in an area where there will be the least amount
of traffic. We suggest that you place the transmitter on top of your audio
source.
Step 3
Operating the transmitter
The green transmit light of the transmitter will be on when audio is
transmitted.
If you are using the speaker outputs, adjust the audio level of your audio
source to the maximum level where no clipping / distortion occurs at the
wireless receivers.
If the audio level supplied to the transmitter is too high, then distortion
will occur. If the audio level is too low, the dynamic range of the
transmission will not be used and the audio level at the receiver may be
too low.
If you are using a line-level audio output and the audio level is too low,
try instead using an audio output with audio volume regulator such as a
headphone output. The transmitter can connect to a headphone output
by using a phone jack-to-phone jack cable.
If audio reception is poor, try raising the transmitter and changing the
transmitter location until reception is acceptable.
If no audio signal is present, the transmitter will go into standby mode
after approximately two minutes. The transmitter will wake up as soon as
an audio signal is present.
