  • Microphone Stand Adaptor

Bodypack Transmitter

  • SVX1 Bodypack Transmitter

  • PG31 Headworn microphone

Power

Plug in the power adapter to turn on the receiver. There is no power switch.

Insert 2 AA batteries into the transmitter. Hold the power button for two seconds to turn on.

Connecting to a Sound System

Connect the balanced XLR output on the receiver to a MIC or LINE input. Set the LINE MIC switch accordingly.

If there is no XLR input, connect the unbalanced 6.35 mm (1/4 inch) receiver output to a LINE input. Set the LINE MIC switch to LINE.

Channel

Set the transmitter and the receiver to the same frequency using the channel dial.

Note: If using a dual system (or more than one single system), assign each input to a different channel within the same group (channels 1-4 or channels A-D). For the JB1 band, there are three groups: channels 1-3, 4-6, and 7-8. This ensures the best signal quality.

Bodypack Gain

The gain dial controls the audio volume sent to the receiver.

  • Turn down the gain if the audio signal sounds distorted.
  • Turn up the gain if the AF LED light is faint or the audio is too low.

RF Level

This switch sets the RF level of the handheld transmitter. It does not affect the audio volume.

  • Set to LO to avoid interfering with other receivers when in a building with multiple systems.
  • Set to HI for transmitting over a greater distance when using a single system.

Squelch

Squelch controls the amount of RF signal that the receiver picks up.

  • Turn up the squelch dial (clockwise) to remove ambient noise from unwanted RF sources.
  • Turn down the squelch dial (counterclockwise) if the microphone is not transmitting clearly to the receiver.

Low Battery Indicator

The transmitter power LED flashes to indicate low batteries.

Color ID Rings

Slide these color rings over the handle of the microphone to identify them. (Sold in a package of six as an optional accessory.)

Getting Good Sound

Correct Microphone Placement

  • Hold the microphone within 12 inches from the sound source. For a warmer sound with increased bass presence, move the microphone closer.
  • Do not cover grille with hand.

Wearing the Headworn Microphone

  • Position the headworn microphone 13 mm (1/2 in.) from the corner of your mouth.
  • Position lavalier and headworn microphones so that clothing, jewelry, or other items do not bump or rub against the microphone.

Wearing the Bodypack Transmitter

  • Clip the transmitter to a belt or pocket.
  • For best results, the belt should be pressed against the base of the clip.

Wireless Tips to Improve System Performance

If you encounter wireless interference or dropouts, try the following suggestions:

  • Replace the transmitter batteries
  • Choose a different frequency channel
  • Reposition the antennas so there is nothing obstructing a line of sight to the transmitter (including the audience)
  • Avoid placing transmitter and receiver where metal or other dense materials may be present
  • Move the receiver to the top of the equipment rack
  • Remove nearby sources of wireless interference, such as cell phones, two-way radios, computers, media players, and digital signal processors
  • Keep transmitters more than two meters (6 feet) apart
  • Keep the transmitter and receiver more than 5 meters (16 feet) apart
  • Keep them away from large metal objects
  • During sound check, mark trouble spots and ask presenters or performers to avoid those areas

Troubleshooting

Problem Solution
No sound
  • Check the power supply of the microphone and receiver.
  • Ensure that the batteries are inserted correctly.
  • Set the transmitter and receiver to the same channel.
  • Check that the receiver is connected to the input on the audio mixer or amplifier.
  • Check that the transmitter is not too far away from the receiver.
  • Decrease (counterclockwise) the squelch.
  • Set the bodypack audio input switch to MIC.
  • Make sure that the receiver has a clear, line-of-sight path to the transmitter.
  • Keep the receiver away from metal objects.
Noise from RF interference
  • Replace the transmitter batteries.
  • Check the receiver antenna location. Make sure there is a clear path between the receiver and the transmitter.
  • When using two or more systems simultaneously, chose different channels within the same group (channels 1-4 or channels A-D). For the JB1 band, there are three groups: channels 1-3, 4-6, and 7-8.
  • Turn off or relocate possible sources of interference such as cell phones, radios, or other electronic devices.
  • Increase squelch (clockwise) to restrict the receiver from picking up ambient noise.
  • Unplug any unused receivers
Audio distortion
  • Adjust levels on the mixer board or sound system.
  • Make sure all cables are securely connected from the receiver to the sound system.
  • If using a bodypack transmitter, lower the gain settings.
