Listening for a Lifetime

Selecting fine audio equipment such as the unit youʼve just purchased is only the start of your musical enjoyment. Now itʼs time to consider how you can maximize the fun and excitement your equipment offers. VocoPro and the Electronic Industries Associationʼs 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 Associationʼs 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

Basic Operations

Using the UHF-28

The UHF-28 can be used as a plug-in module or as a stand-alone module. In both setups, the function of the UHF-28 is the same.

To use the UHF-28:

1. Plug in all power sources.
2. Switch on the your main unit and the UHF-28.
3. Switch on the wireless microphone.
4.  Adjust the volume using the UHF-28s volume control, and using the mic input volume control on your main unit.

When using the UHF-28 as a plug-in module, (SOUNDMAN, DVD-SOUNDMAN, HERO-RV, CHAMPION-RV) the UHF-28 will use two of the input channels. Be sure to determine which inputs are being used, as plugging a wired mic or instrument into that input channel might switch off the wireless microphone.

To determine which input channel the UHF-28 is using (SOUNDMAN, DVD- SOUNDMAN, HERO-RV, CHAMPION-RV):

1. Turn all the individual input channel volume controls down.
2. Speak into the wireless microphone while turning up each input channel independently.
3. Make a note of which input channel the UHF-28 is using so that no cables are plugged into that input channel while the UHF-28 is in use.
