What’s in the Box:

Quick start

1. Connect the supplied power adapter (12V/1A) and antennas to the receiver.
2. Connect another power adapter (12V/1A) to the charger station.
3. Connect the microphone sound to your karaoke player, mixer or mixing amplifier.
4. Turn on the receiver and select desired channels for both microphones.
5. Install rechargeable batteries in microphones and turn them on.
6. Press the SET button on the left side of the receiver and align the microphone towards the receiver to set the frequency.
7. Press the SET button on the right side of the receiver and align another microphone towards the receiver to set the frequency.
8. Adjust the microphone volume to a value of 18 using the VOL buttons on the receiver.
9. Adjust the microphone volume on the mixer and check the microphone sound. If the sound is too weak, increase the amplifier’s volume. If the microphone sound is distorted, decrease the volume on the receiver and increase the volume on the amplifier.

Notice:

• AV amplifiers don’t have microphone inputs, so you cannot connect the receiver directly to your AV amplifier. If your AV amplifier has microphone input it’s usually used for automatic adjustment of the system.
• Microphone frequency won’t change automatically when changed on the receiver. You must send the frequency using the SET button on the receiver and aligning the microphone towards the receiver.

Receiver

Front Panel:

Notice! VOL-, CHANNEL- ja SET-buttons on the left side are for microphone channel A and buttons on the left side are for microphone channel B.

1. VOL: Volume controls for microphone channels. The typical value of 18 is suitable for most mixers. Setting the microphone volume too high may cause distortion in the microphone input of the mixer. Lower the volume from the receiver if the microphone sound is distorted.
2. CHANNEL: Set microphone channel frequency by pressing shortly. The left side has channels 0 – 16 ja right side has channels 17 – 33. Notice! If you keep the CHANNEL button pressed, the receiver scans the frequency range and sets the channel which has minimum interference.
3. SET/LOCK: Press shortly to send the frequency of the channel to the microphone using an IR transmitter. Align the microphone towards the receiver during sync. You can lock the receiver’s buttons by keeping the button pressed a long time. ”LC” on the display indicates that the buttons are locked. Remove the lock by keeping the button pressed again. ”LC 0″ on the display indicates that the lock is removed.
4. POWER BUTTON: Keep the button pressed to turn the power on or off.
5. RF/AF: RF indicates wireless signal strength and AF indicates the audio signal level of the microphone channel.
6. FREQUENCY: Currently used frequency of the microphone channel.
7. IR TRANSMITTER: The receiver can send the frequency to the microphone using an IR transmitter. Along the microphone towards this point during sync.

Back panel:

1. ANT-B: Install the antenna for the wireless microphone B.
2. BALANCED-B: Balanced XLR output for wireless microphone B. The cable is sold separately.
3. MIX A+B: Unbalanced 1/4″ TS jack for mixed output (microphone 1 + microphone 2). Connect the mixed microphone sound to the mixer using the supplied mono plug cable.
4. POWER INPUT: Connect the supplied power adapter (12V/1A).
5. BALANCED-A: Balanced XLR output for wireless microphone A. The cable sold separately.
6.  ANT-A: Install the antenna for the wireless microphone A.

Wireless Microphone

Functions

1. GRILL: Removable metal grill protects a cartridge from damage and an inner foam filter reduces wind, breath, and pop noises.
2. IR: IR receiver for setting the frequency of the microphone. Align this point towards the receiver during sync.
3. DISPLAY: Display indicates currently used frequency and battery level. If the battery level indicator is blinking, it means the battery level is low. Low battery levels may cause dropouts or complete signal loss. Please charge the batteries immediately.
4. POWER BUTTON: Keep the button pressed a moment to turn the microphone on or off.
5. BATTERY COVER: Battery compartment for two rechargeable ’AA’ batteries. Remove batteries if the microphone is not used for a long time.
6. CHARGING CONTACTS: Charging contacts on the bottom of the wireless microphone.
   Do not charge non-chargeable batteries!

Please handle the wireless microphone with care.
The warranty does not cover damage caused by an accidental misuse of the product.

Operation

1. Open the battery cover by turning the cover counterclockwise. Install two rechargeable ’AA’ batteries and close the cover. Pay attention to the correct polarity.
2. Turn on the microphone by keeping the power button pressed for a while. Currently, the used frequency is shown on the display.
3. Check that the microphone’s and receiver’s frequencies are the same. If the frequency doesn’t match, send the frequency by shortly pressing the SET button on the receiver and aligning the microphone towards the receiver.
4. The receiver’s RF level indicator should turn on now to indicate a connection between the wireless microphone and the receiver.
5. Turn off the microphone by keeping the power button pressed a while.

Notice:

• Receiver’s channel A has frequency channels of 0-16 and channel B has frequency channels of 17-33. Microphones are not limited to working only at channels A or B, so both microphones can be set to channels 0 to 33.
• Make sure that both microphones are not set at the same frequency channel. This will cause signal degradation and complete signal loss.
• The microphone frequency is always changed by pressing the SET button on the receiver. You cannot change the frequency from the microphone.

Charging Dock

Functions

1. Charging socket 1.
2. Charging indicator light for socket 1.
3. The power light turns on when the power adapter is connected.
4. Charging indicator light for socket 2.
5. Charging socket 2.
6.  Connect the supplied power adapter (12V/1A).

Operation

1. Connect the power adapter (12V/1A) to the DC jack on the back side of the charging dock.
2. Install rechargeable ’AA’ batteries in the microphone and put the microphone in one of the charging sockets.
3. The charging light is on while the battery is charging and turns off after the battery is fully charged.

Note! Do not charge non-chargeable batteries. The non-chargeable battery will overheat and the seal breaks causing the battery to leak or explode.

Getting Connected

Operations Before Connecting the Receiver

1. Install antennas to the back panel of the receiver.
2. Connect supplied power adapter (12V/1A) to the power input of the receiver.
3.  Connect another power adapter (12V/1A) to the back side of the charger station.

Connecting the Receiver
U-TUBE 20PD receiver can be connected to the mixer, mixing amplifier or karaoke player equipped with microphone inputs. A typical connection diagram of the system can be found below.

The connection can be made from the mixed output (MIX A+B) using the supplied unbalanced 1/4″ TS plug cable. In this case, both microphones are connected using only one cable, so it’s not possible to change microphone sound settings individually for each channel in the mixer. Please check the connection example on page 12.
Alternatively, both microphones can be connected separately to the mixer using Balanced Outputs. In this case, two cables are used to make the connection, so it’s possible to change microphone sounds settings individually for each channel in the mixer. The connection can be made using the following cables depending on the microphone input connector type:

• XLR female – unbalanced 1/4″ TS plug cable,
• XLR female – XLR male cable,
• XLR female – balanced 1/4″ TRS plug cable
  The last two of the cables are balanced, which reduces interference picked up on the cables. Please check the connection examples on pages 13-15.

Connecting the Microphones
Install the batteries and turn on the microphone. Press the SET button on channel A on the receiver and align the microphone towards the receiver. Check the frequency on the microphone. Repeat the procedure for another microphone, but this time press the SET button on channel B.
