Selecting Channels; Troubleshooting - Shure PSM700 User Manual

Selecting Channels

The PSM700 system offers a total of 32 channels. These are split into two groups: Group 1 (channels 1–16)
and Group 2 (channels 17–32). Change channels if you encounter interference or need to operate more than
one system at a time.
• The transmitter and receiver must be set to the same group and channel.
• Multiple systems must use different channels.
• Use the supplied screwdriver to rotate the channel control.
Channel Scan Mode
If you have difficulty finding a clear channel, use the receiver's Channel Scan Mode. Normally, the receiver mutes if it
does not detect a signal from the transmitter. In this mode, the receiver remains unmuted, so you can listen for interference.
1. Turn off all PSM700 transmitters (leave other wireless systems on).
2. Set the receiver to group 1 (DIP switch 1 UP) and channel 1 (rotary channel select).
3. Lower the volume on the receiver to a minimal level and insert the earphones.
4. Turn on the receiver and, within 5 seconds of power up, flip DIP switch 1 down and up again.
5. Listen to all the channels in groups 1 and 2:
• Clear channels will produce pure, uninterrupted white noise.
• Any noises like clicks or buzzes indicate interference from another device.
6. Turn the receiver off and on again to return to normal operating mode. Select the channel with the least interference.
Monitoring the Performers' Mixes
When setting up multiple systems, use an extra receiver to check and monitor each transmitter. Set the group
and channel controls on the extra receiver to whichever transmitter you want to monitor. If necessary, adjust the
balance control to check for proper stereo or MixMode operation.
