Overall Wireless Microphone Market

Most wireless microphones today Analog audio transmission Unlicensed in the UHF range

TV going digital, Feb ‘09, freeing up UHF frequencies FCC auctioned UHF frequencies to Cell Phone Service Providers. RESULT: Unlicensed wireless devices will not be able to use

Red/green, mute/power indicator Charger Base must be plugged into AC

power outlet

Mute Switch Mutes all microphones, only if linked with Base Station

Linking with Base Station To enable, press Learn button on the rear of the Base

Station and press the Mute button twice To disable, hold the Learn button on the Base Station for 10

seconds and release

29

Multi-Channel Systems: Change the Transmit Power Level

Lowering RF power output can keep units from interfering with other local systems

Even number pairing buttons (2, 4, 6, 8) used to change the RF transmit power

Press and hold the buttons while switching on the AC Release at:

1 flash = full power (100’, 30m - default) 2 flashes = mid power (50’, 15m) 3 flashes = low power (8’, 2.5m)

62 84

30

Interleaving Multi-Channel Base Stations

Odd number pairing buttons (1, 3, 5, 7) must be used to change the Channel Modes in multi unit synchronized base stations

Press and hold the buttons while switching on the AC Release at:

1 flash = default for 4 or 8 channel single unit 2 flashes = A channel mode for Local unit 3 flashes = B channel mode for Remote unit

51 73

31

Syncing Multiple Multi-Channel Base Station Frequencies for up to 16 channels

1. Set one Base Station for Channel Mode A and other Base Station to Channel Mode B using the Odd pairing buttons

2. Set the Local / Remote switch to Remote on the Channel Mode B unit. For a 12 channel system, set the 4-channel system to Local

3. Put the units in the top of a rack Local unit on top of Remote

Local antennas pointed up with 90 degree angle Remote antennas pointed to floor with 90 degree angle

Connect Sync Cable Power on Local unit and then Remote unit

4. Pair all microphones to channels Do one Base Station/one channel at a time

Solo Single Channel

Single Channel System: Change the Transmit Power Level

Mute switch used to change the transmit power level

Press and hold the Mute switch while plugging in the AC adapter cord and release when LED flashes: 1 flash = full power (65’, 20m) default 2 flashes = mid power (30’, 10m) 3 flashes = low power (6’, 2m)

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

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
