Each transmitter and receiver pair must be the same frequency, or channel. The
Shure wireless system uses transmitter setup to synchronize the transmitter and
receiver channels.
Note: transmitting devices such as cellular phones may interfere
with wireless audio transmissions. Keep transmitters and receiv-
ers away from these and other potential sources of interference.
Single wireless system set-up.
1. Automatic Group Scan: Press and release the group button on the receiv-
er. This scans for a clear channel and sets the receiver to that channel.
2. Transmitter Setup: Transmitter group and channel must be manually set to
match the receiver.
After manual setup, the transmitter alternately displays the group and
channel setting for about two seconds.
Transmitter Locking Feature
Turn the transmitter on. Hold the group button, then press the channel
button for approximately 2 seconds. The LED indicator rapidly flashes
red when locked. Repeat to unlock.
Choosing an input.
mic in
line in
Plug a microphone with an
XLR connector into mic input.
The knob above the jack con-
trols the volume level.
The mic input is balanced and low
impedance for superior hum rejection.
Best performance will be obtained
with a MIC-HH1 or equivalent dynamic
low impedance microphone with XLR
connector.
When using long mic cables, use a
balanced microphone to help prevent
hum and interference.
Plug a line-level source with
a 1/4” phone plug (cd player,
metronome, music instrument,
etc.) into the line input. The
knob above the jack controls
the volume level.
The line input is an unbalanced Hi-Z
line level input.
Use shielded cable to avoid hum or
interference.
To daisy-chain two sound systems
together for greater crowd coverage,
connect the line output from one sys-
tem into the line input of the other.
