Setup Receiver Antennas

• Determine area of operation of transmitters.
• Determine receiver antenna locations for best
  line-of-sight to transmitters.
• Locate receiver antennas no closer than 15 feet
  to nearest transmitter.
• Elevate receiver antennas well above the audience
  or other obstructions.
• Locate diversity antennas at least two feet apart
  
• Keep antennas at least one foot away from other
  metal objects.
• Keep antennas at least two feet away from RF
  noise sources such as digital audio processors,
  video devices, CD/DVD players, computers, etc.

5
Setup Receivers

• Programming receivers
• Within a given band, ALL systems should be set to
  the same Group and different CHANNELS within that
  Group. DO NOT MIX GROUPS!
• DO NOT USE LETTER GROUPS A1-A9, B1-B4 unless
  specifically instructed
• Set output mic/line switches as necessary.
• Set front panel output level controls fully
  clockwise

6
Setup Transmitters

• Program transmitters to match receiver Group and
  Channel set.
• Set transmitter audio levels
• Bodypack transmitter set input attenuation
  accordingly for lavalier microphone, headworn
  microphone.
• Handheld transmitter and bodypack transmitter
  adjust gain control in battery compartment so
  that red LED peak light on receiver just flashes
  on LOUDEST sound

7
Pre-show Checkout

• Verify good batteries in each transmitter
• Turn OFF all transmitters
• Turn ON all receivers
• Observe RF signal LED strings on receivers
• 0-2 LEDs on either side channel is OK
• 3 or more LEDs on either side channel has
  excessive interference. Change to another
  compatible channel
• Turn on each transmitter ONE at a time to verify
  signal at corresponding receiver
• Turn on all transmitters to verify signals at all
  receivers

8
Pre-show Checkout

• Conduct a walk around test for each transmitter
  throughout the performance area
• If locations of low RF are found, reposition
  receiver antennas to compensate if possible.
• If set pieces or other fixed obstructions are
  problematic, the allowable performance area may
  have to be modified.

9
Show Operation

• Turn on required receivers.
• Mute or turn off unused receivers
• Turn on required transmitters. Transmitters must
  be at least 15 feet from nearest receiver
  antenna.
• Verify reception at receivers
• Place transmitters with participants
• Attach to participant as high on the body as
  possible breast pocket of jacket, belt, etc.
• Do not fold or shorten bodypack antenna
• Position lapel microphone as close as possible to
  mouth knot of tie, collar, lapel, etc.
• Aim directional microphones toward mouth

10
Show Operation

• Position omnidirectional head-worn microphone at
  corner of mouth
• Position unidirectional head-worn microphone
  slightly forward and to the side of mouth
• Power lock transmitter if desired (press and hold
  Mode and Set buttons together).
• Monitor RF levels during show on the receivers
  front panels
• Monitor audio directly on headphone outputs on
  receiver front panels

11
General tips

• TURN OFF ALL mobile phones, Blackberrys, Trios,
  etc.) in the performance area
• In particular participants. Units must be
  COMPLETELY OFF, not just on silent.
• Do not cue up un-occupied receivers in the sound
  system. Receivers without active transmitters
  should be muted or turned off.
• Do not set up system with some transmitters very
  close to receiver antennas and other transmitters
  far away. The nearby transmitters can desensitize
  ALL receivers.

12
General tips

• In the UHF range, line-of-sight is critical
  elevate receiver antennas as high as necessary to
  see the transmitters at all times.
