Choosing an input.
mic 1
mic 2 / line
Plug a microphone with an
XLR connector into mic input
one or two. The knob above
the jack controls the volume
level.
The mic inputs are balanced and
low impedance, and supply phantom
power (
10 volts
) for condenser type
microphones.
When using long mic cables, use a
balanced microphone to help prevent
hum and interference.
Plug any line-level source
with a 1/4” phone plug (tape
player, music instrument,
etc) into the line input. The
knob above the jack controls
the volume level.
The line input is an unbalanced 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.
Wireless system set-up.
Each transmitter and receiver pair must be the same 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 Channel Scan: Press and release the group button on the
receiver. 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. This feature keeps users from
changing the channel accidentally.
