• Troubleshooting

40
RF/Battery Problem Symptoms

• Synching problem- usually RF related
• LED cycles Red-Yellow-Green and mic beeps
• Poor audio quality and dropouts
• Mics lose pairing for no reason
• Mics turn off for no reason
• Battery issues- not usually RF related
• Green cycles with yellow un-muted low battery
• Double Red cycles with yellow muted low battery
• Mic will not charge
• Mic gets warm to touch
• Do not let mic die (full discharge), if possible

41
Usual RF Problems

• Common Causes
• Metal Rack Doors (Plexiglas OK)
• Brick, cinderblock or steel construction
• Air Walls (partitions)
• Antennas not facing toward room
• Electrical or lighting panels in line of sight
• Multiple Solo systems not synchronized
• 90 of all Battery issues are actually RF
  problems

Two 4-channel systems and one 8-channel system in
opposing racks not synced
42
Avoid Syncing Problems

• Take out mics one or two at a time
• Not handfuls
• Space mics appropriately around the room
• Not in a stack next to the Base Station
• Avoid putting 16 CH systems in adjoining rooms
• Use minimum 50 to 100 spacing between systems
• Do not use a Single Channel unit with a
  Multi-Channel system in the same space

43
Configuration Problems

• Mixer gain structure set incorrectly
• Video-conferencing settings incorrect
• Each DSP VTC brand is different
• Configuration help for AV Systems

44
Setting Mixer Audio Levels

• Line Level 0dBu at Mic/Line Input (mic level will
  cause distortion)
• No phantom power (phantom will cause distortion)
• High pass filter at 150 Hz
• Low Pass filter at 7000 Hz
• Noise Cancelation set at 6 to 10 dB
• Add mic gain up to 10 dB if you need more,
  something is cabled wrong or gain structure needs
  adjustment
• On Biamp add 20ms delay on AEC Ref

45
Example 2 Setting Nexia AEC

• Add a delay of 20ms to increase AEC tail by
  compensating for latency
