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.

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

  1. Start by attaching the antenna to the receiver. The antenna will connect to the sockets on the back of the receiver labelled ANT-A and ANT-B. Screw the antenna on by twisting clockwise until they are tight.
  2. Get the power adapter, connect the small end to the DC INPUT on the back of the receiver and plug the other end into a wall socket or power strip.VOCOPRO UDX Series 8 Digital PLL Wireless Rackmount Microphone - Getting Connected
  3. Connect the receiver to your mixer, amplifier, or powered speaker by using the audio outputs on the back of the receiver. There are 3 different options available on the UDX-OCTO receiver. Using option 1 or 2, you will have to use the volume controls on the UDX-OCTO receiver to control the volume for your mics. Using option 3 will allow you to set the initial volume output on the receiver, and then control the volume from your mixer after setup.
    Option 1: Using the ¼ inch Mixed Out
    If the device you are connecting to only has ¼ inch mic inputs, the easiest way to connect will be using the ¼ inch mixed out. Using the included ¼ inch audio cable, connect one end to the ¼ inch MIX OUT on the receiver and connect the other end to the mic input on your device.

Connected 1

Option 2: Using the XLR Mixed Out
If you are connecting to a device that has XLR mic inputs, but does not have enough inputs for all of your microphones to be connected individually, then you can use the XLR MIX OUT. Using a standard XLR cable (not included) connect the female end of the cable to the XLR MIX OUT on the receiver and connect the male end of the cable to the mic input on your device.VOCOPRO UDX Series 8
Digital PLL Wireless Rackmount Microphone - Mixed OutOption 3: Using the individual XLR Outputs
If you are connecting to a large mixer that has enough XLR mic inputs for all of your mics, you can use the individual XLR outputs. Use standard XLR cables (not included) to connect from each channel output that you are using to an input on your mixer.
Ex: If you are only using 6 transmitters on channels 1 thru 6 on the receiver, you do not need to connect all 8 outputs from the receiver, only channel 1 thru channel 6, only the channels you are using.VOCOPRO UDX Series 8 Digital
PLL Wireless Rackmount Microphone - Mixed Out 1

Syncing the Transmitters to the Receiver

Once we have the receiver hooked up, we can begin syncing the transmitters to the different channels on the receiver.
First, make sure all your transmitters have fresh, good quality batteries installed, and they are all powered on. Check the battery indicator on each transmitter.
Power on the receiver and wait a couple seconds for the system to start up.
Choose the channel you want to pair to, and hold down the IR Button on that channel until the IR light on the receiver begins flashing, about 3 seconds.
Hold the IR sensor on the transmitter up to the IR light on the receiver. For the UDX-HT handheld mic and the UDX-CF conference mic, the IR sensor is built into the display screen so you simply need to point the screen at the IR light. For the UDX-BP body pack, the IR sensor is under the battery cover so you will need to open the battery cover and point the front towards the IR light.VOCOPRO UDX Series 8 Digital PLL Wireless Rackmount Microphone -
Syncing the TransmittersOnce the transmitter and receiver are in range of each other, it will only take a second for them to pair.
You can check that they are paired by looking at the receiver’s display. It should show that the RF meter is getting signal, the volume is not muted, you should be able to see the transmitter’s battery life, and if you speak into the microphone the AF meter will show signal.
See the comparison between a channel that is synced to a transmitter, and one that is not.VOCOPRO UDX Series 8 Digital PLL Wireless Rackmount Microphone -
Syncing the Transmitters 1 Please Note:
Once the IR button begins flashing, you have about 20 seconds to pair a transmitter. After you pair a transmitter, or if 20 seconds passes without pairing, the IR light will stop flashing. If you want to stop the pairing process before the 20 seconds are up, simply press any of the IR buttons and the light will stop flashing.
You will need to pair each transmitter individually, and to a separate channel. So as an example, let’s say we have two UDX-HT handheld mics, one UDX-BP bodypack, and one UDX-CF conference mic, and we want to pair them to channels 1 thru 4 on the receiver. We’ll need to hold down the IR button for channel 1 until the light flashes, then hold a handheld mic up to the receiver to pair. Then hold down the IR button for channel 2 and hold up the second handheld mic up to the receiver. Then hold down the IR button for channel 3 and hold up the bodypack to the receiver to pair. And finally hold down the IR button for channel 4 and hold up the conference transmitter base to pair.
When you first turn on the UDX-OCTO receiver, channels 1 through 8 will all be set to different frequencies. So you can go ahead and sync your transmitters to each channel, following the instructions in the previous section, and you should be good to go.
The 900 MHz range is fairly open space so it is unlikely you will run into interference.
If you do experience any interference or audio cutting out issues, or if you already have some 900 MHz equipment you need to work around, you can change the frequencies for each channel on the receiver, and then re-sync your transmitters.
There are two methods to changing the frequency on each receiver channel:
Option 1: Scanning for open frequencies
Pick the channel you want to change. With the receiver powered on, push and hold the channel setup button until the screen is unlocked.
Push the setup button so you have SCAN on the right highlighted in blue, and there is no channel number on the left.VOCOPRO UDX Series 8 Digital PLL
Wireless Rackmount Microphone - Syncing the Transmitters
1Now you can turn the knob and it will scan for the next available frequency, in increments of 0.1 MHz.
In Scan mode it will only allow you to select open frequencies.
For example, if you are scanning on channel 6, it will normally scan from 918.2 MHz up to 921.3 MHz. If you have something nearby transmitting at 920.1 MHz, then it will leave a large gap of frequencies in the middle to avoid that signal. You can turn the knob and scan up to around 919.0 MHz then it will jump up to around 921.3 MHz.
It leaves a large gap of open frequencies, and the ‘edges’ of that gap may fluctuate a bit because the frequency of the transmitters can fluctuate a little bit.
After using either method to set the frequency, you will need to re-sync the transmitter for that channel, using the instructions in the previous section.
Option 2: Setting a specific frequency
Pick the channel you want to change. With the receiver powered on, push and hold the channel setup button until the screen is unlocked.
Push the setup button so you have CH-# on the left highlighted in blue, and there is a channel number below.VOCOPRO UDX Series 8 Digital PLL Wireless
Rackmount Microphone - specific frequencyNow you can turn the knob to select any MHz frequency, in increments of 0.1 MHz, within the range for each channel.
After using either method to set the frequency, you will need to re-sync the transmitter for that channel, using the instructions in the previous section.

Troubleshooting

Equipment is not turning on:
For the Receiver:

  • Make sure the power adapter is securely connected to the receiver and to your outlet or power strip.
  • Check that the outlet or power strip is getting power, try plugging another device into the outlet.
  • Ensure your power adapter is the original adapter or that its output rating fits within the range specified in the previous section.

For the Transmitters:

  • Make sure you have new, good quality batteries, and that they are installed in the correct orientation.
    Transmitter is not connecting to the receiver or is cutting out during use:

  • Check to see if the frequency on the transmitter matches one of the channels on your receiver.

  • Make sure the transmitter indicates good battery life remaining.

  • Try scanning for a new open frequency on the receiver, and resyncing the transmitter.

  • Make sure the antenna are securely connected to the back on the receiver and pointed upward.

  • Ensure you are within range of the receiver and have clear line of sight between the transmitter and the receiver’s antenna.

Transmitter is connected but I hear no audio:

  • Make sure the transmitter is not muted, will read MUTE on the display if it is.
  • Check the volume setting on the receiver channel. For the bodypack also check the volume knob.
  • Speak into the mic and see if the AF meter on the receiver shows signal.
  • Ensure the receiver is properly connected to your sound system, either through one of the MIX OUT connections or the corresponding individual CH-# output.
  • Plug a wired microphone into your sound system to see if you are getting audio.

For the best sound reception:

  • Make sure the transmitters have good battery life, if the indicator is low try new batteries to compare.
  • Make sure the volume is turned up on the receiver, and on your sound system.
  • When speaking into the microphone, make sure the mic pickup is within 1-2 inches of your mouth.
  • For the handheld and conference mic, you want to be speaking into the top of the microphone as if you are speaking down the tube.
  • For the headset mic, move the boom arm so the pickup is directly in front of your mouth, and rotate the boom arm so the pickup is pointing towards it. Remove the windscreen to see the pickup orientation.
