Listening For A Lifetime

Selecting fine audio equipment such as the unit you've just purchased is only the start of your musical enjoyment. Now it's time to consider how you can maximize the fun and excitement your equipment offers. VocoPro and the Electronic Industries Association's Consumer Electronics Group want you to get the most out of your equipment by playing it at a safe level. One that lets the sound come through loud and clear without annoying blaring or distortion and, most importantly, without affecting your sensitive hearing.

Sound can be deceiving. Over time your hearing “comfort level” adapts to a higher volume of sound. So what sounds “normal” can actually be loud and harmful to your hearing. Guard against this by setting your equipment at a safe level BEFORE your hearing adapts.

To establish a safe level:

• Start your volume control at a low setting.
• Slowly increase the sound until you can hear it comfortably and clearly, and without distortion.

Once you have established a comfortable sound level:

• Set the dial and leave it there.
• Pay attention to the different levels in various recordings.

Taking a minute to do this now will help to prevent hearing damage or loss in the future. After all, we want you listening for a lifetime.

Used wisely, your new sound equipment will provide a lifetime of fun and enjoyment. Since hearing damage from loud noise is often undetectable until it is too late, this manufacturer and the Electronic Industries Association's Consumer Electronics Group recommend you avoid prolonged exposure to excessive noise. This list of sound levels is included for your protection.

Some common decibel ranges:

Level	Example
30	Quiet library, Soft whispers
40	Living room, Refrigerator, Bedroom away from traffic
50	Light traffic, Normal Conversation
60	Air Conditioner at 20 ft., Sewing machine
70	Vacuum cleaner, Hair dryer, Noisy Restaurant
80	Average city traffic, Garbage disposals, Alarm clock at 2 ft.

The following noises can be dangerous under constant exposure:

Level	Example
90	Subway, Motorcycle, Truck traffic, Lawn Mower
100	Garbage truck, Chainsaw, Pneumatics drill
120	Rock band concert in front of speakers
140	Gunshot blast, Jet plane
180	Rocket launching pad

Microphone basics

Microphone Position

The UHF-5805 is ideal for close-up vocals and can be held in the hand or mounted on a mic stand. The most common applications and placement techniques are listed below. Keep in mind that microphone technique is largely a matter of personal taste, and there is no one “correct” microphone position

Proximity Effect

When the sound source is less than 14 in. from the microphone, the microphone boosts bass frequencies (by 6 to 10 dB at 100 Hz), creating a warmer and richer bass sound than when farther away. This effect, known as proximity effect, happens only in unidirectional dynamic microphones like the UHF-5805.

Feedback

Feedback occurs when the amplified sound from any loudspeaker reenters the sound system through any open microphone and is repeatedly amplified. Most commonly, feedback is caused by the following conditions: placing loudspeakers too close to microphones, having too many open active microphones, boosting tone controls indiscriminately (mainly treble) and performing in areas with high ratios of room surfaces that have hard and reflective surfaces such as glass, marble and wood. What to do if feedback occurs before the sound system is loud enough?

• Request that the talker speak louder into the microphone.
• Reduce the distance from the talker to the microphone. Each time this distance is halved, the sound system output will increase by 6dB.
• Reduce the number of open microphones.
• Move the loudspeaker farther away from the microphone. Each time this distance is doubled, the sound system output can be increased by 6dB.
• Move the loudspeaker closer to the listener.
• Use an equalizer/feedback reducer to cut the frequency bands in which the feedback occurs.

Microphone Placement & Tone Quality

Lead & Backup Vocals

Lips should be less than 3" from or even touching the windscreen on an axis to the microphone. Doing this creates a robust sound, emphasizes bass and provides maximum isolation from other sources.

Speech

When giving a speech or simply speaking, place the microphone 4" to 10" away from the mouth, just above nose height for a natural sound with reduced bass. You can also place the microphone 8" to 16" away from the mouth, slightly off to one side, for a more "distant" sound with highly reduced bass and minimal "s" sounds.

System Connection

1. Connect the AC POWER ADAPTER to the UHF-5805 receiver's POWER INPUT connector, then plug the ADAPTER into a compatible AC electrical outlet.
2. Connect the UHF-5805's receiver to a sound system, mixer or amplifier's microphone input(s) with either one 1/4" output jack for a mixed channel output, or up to four XLR output jacks for separate output for each mic.

Deciding Between Mixed or Separate Output

Mixed Channel Output

Pro: Uses only 1 mic input on an external mixer/amplifier.

Con: External mic adjustments are only applied to one mic channel.

Separate Channel Output

Pro: External mic adjustments can be applied on one or both mic channels.

Con: Uses up up to 4 mic inputs on mixer/amplifier.

Antenna Connection

Insert the antenna's TNC connector into the TNC jack and twist clockwise until it is firmly secured.

Maintenance procedures

Removing the Field Replaceable Modules

Each of the 4 microphone modules on the UHF-5805 were designed in a way that allows them to slide out. This is a convenient feature if ever a module needs to be repaired or replaced

1. Remove the two screws that fasten the module to the front panel.
2. To remove the module, simply slide the module out of the compartment
   NOTE: It might be helpful to use a flat-head screwdriver to nudge the module out of its compartment.
3. To re-insert, slide the module into compartment until it is completely secured. Secure the module with the screws.

Charging the Microphones

The UHF-5805 comes with two dual chargers that let you charge all four microphones at the same time.

Charging the Microphones

If the LED light on the microphone[s] does not light up when the microphone is turned on, this indicates that the microphone needs to be charged

To charge

1. Place the microphone in the charger slot, the LED on the charger will be lit while the microphone is charging.
2. When the LED on the charger turns off, the microphone is charged and can be removed.
   NOTE: For longest battery life, be sure to turn the microphones off when not in use.

Reading the LED Indicators

The LEDs on the charger indicate the charging status. There are three states: blinking, on, and off.

• Blinking - The power is connected to the charger but there are no microphones being charged
• On - The microphone is being charged
• Off - The microphone is completely charged and can be removed.

Charger and Microphone Descriptions and Functions

11. XLR AUDIO OUTS - These XLR unbalanced output jacks are for output connections to amplifiers, effects devices or mixers. These are for separate mic channel connections with unmixed mic output.

UHF-5805 & stage monitor/p.a. loudspeakers

If you will be using the UHF-5805 with stage monitors and/or P.A. system, try the following

• Place the stage monitor directly behind the microphone.
• Locate the P.A. loudspeakers so that they point away from the rear of the microphone. [With the speakers located in these positions, the possibility of feedback is greatly reduced].
• Always check the stage setup before a performance to ensure optimum placement of microphone and monitors

IMPORTANT: Every wireless microphone installation is a unique situation, and can present a variety of problems. Never attempt a live performance without first conducting a "walkthrough" test of the system in the performing area. If major changes [additional wireless systems or intercoms, relocation of scenery, etc.] have been made since the last walk-through test, check the wireless system again, as close to performance time as possible.

2. Adjust the receiver's VOLUME controls to approximately 50%.
3. Switch the microphone's POWER BUTTONS to the ON positions.
4. Talk or sing into the microphones. During normal operation, the RF/AF signal LED's will light when a microphone is being used.
5. Adjust the receiver's VOLUME controls until the output levels are balanced with each other and other possible source output i.e. CD+G tracks.

Troubleshooting

Problems	Solutions
No sound output, RF/AF LED(s) are not glowing	Make sure the microphone and receiver power switches and receiver are set to the ON position.Check microphone charge to ensure there is sufficient power. Charge mic if necessaryCheck receiver's AC power connectionMake sure antennas are firmly connected and extended to an optimal position.If necessary, reduce the distance between the microphones and receiverTurn up the receiver's VOLUME level controls.Check for proper connection between receiver and external amplifier/mixerTalk into the microphone and observe the receiver's RF/AF signal LED's. If they glow, the problem is elsewhere in the sound system.
Received signal is noisy or contains extraneous sounds with the microphone(s) ON.	Check microphone(s) charge and recharge if the charge is lowRemove local sources of UHF interference, such as lighting equipment.Adjust the squelch controls on the front of the UHF-5805 receiverSignal may be too weak. If so, reposition antennas. (If possible, move them closer to the transmitter).
There is noise coming from the receiver with the microphones turned OFF	Remove local sources of UHF interference, such as lighting equipment.Reposition the receiver or antennas.
Momentary loss of sound as microphone(s) are moved throughout the operating range	Reposition the receiver, perform a "walkthrough", and observe the signal strengths. If audio dropouts persist, mark these "dead spots" in the operating area and avoid them during the performance.
Erratic LED blinking on the main receiver modules	Make sure the 14V power adapter is plugged in to the main unit. Do not use the 9V adapters with the main receiver unit.If the power adapter is the 14V and the main unit lights are still blinking, contact VocoPro for a replacement
