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

Getting Connected

CONNECTING POWER

Connect the AC power adapter to the power input jack on the far right of the back panel on the VHF-4005.

CONNECTING AUDIO OUTPUT

USING THE XLR OUTPUTS:

The XLR outputs allow you to connect each channel to the mixer independently. This gives you more control over the volume on individual microphone channels when connected to a mixer. You’ll need:

• VHF-4005
• (4) XLR patch cables (not included)
• An input device, such as a mixer or amplifier (not included)

TO CONNECT THE XLR OUTPUTS:

• Ensure the main power switch is turned off.

• Connect one end of an XLR cable to the CH.1 output of the VHF-4000.

• Connect the other end of the XLR cable to the desired input on your mixer.
  Note: To avoid confusion, it’s recommended that the XLR jacks are attached correspondingly (e.g. CH.1 to CH.1, CH.2 to CH. 2, etc. illustration is for clarity not accuracy).

• Repeat steps 2 and 3 until all the XLR outputs are connected.

USING THE 1/4” MIXED OUTPUT:

The 1/4” mixed output is useful if you have limited inputs available on your mixer. All four microphone signals are mixed together in this single output. You’ll need:

• VHF-4005
• (1) 1/4” patch cables (included)
• An input device, such as a mixer or amplifier (not included).

TO CONNECT THE 1/4” MIXED OUTPUT:

• Ensure the main power switch is turned off.
