Receiver Controls and Connectors

Front Panel

  1. audio LED: Indicates strength of incoming audio signal: green for normal, amber for strong and red for clipping.
  2. LED Screen: Displays group and channel setting. See "Single System Setup" for details.
  3. channel button: Changes group and channel setting. See "Single System Setup" for details.
  4. ready LED: Indicates system ready and receiving an RF signal from the transmitter. Also indicates battery level of the transmitter:
  • Green = transmitter battery level normal
  • Red = low battery (typically less than 60 minutes with alkaline batteries)
  • with NiMH rechargeable batteries, when the indicator turns red there will be little to no remaining life.

  • Infrared (IR) port: Sends IR signal to transmitter for sync.
  • sync button: Press to synchronize transmitter with receiver group and channel settings.
  • AC adapter jack
  • Adapter cord tie-off
  • XLR microphone output jack
  • 6.35 mm (¼") instrument level output jack
  • Back Panel

    Transmitter Controls and Connectors

    ① Indicator LED: Displays battery level, mute, and IR transmission status (see table).

    ② Power/Mute Switch: Press to mute or unmute. Press and hold to power on or off.

    ③ Infrared (IR) port: Receives infrared beam to synchronize frequencies. When using multiple systems, only one transmitter IR port should be exposed at a time.

    ④ 4-Pin Microphone Input Jack

    ⑤ Audio Gain Adjustment

    Transmitter Indicator LED

    LED Indicator Status
    Green Ready
    Flashing green Controls locked
    Amber Mute on
    Solid red Battery power low
    Flashing red Batteries dead (change batteries to power on transmitter)
    Rapidly flashing red IR transmission in process
    Flashing amber and red Battery power low and mute on

    Batteries

    • A fresh set of alkaline batteries lasts up to 10 hours (9 hours, PGXD2).
    • The transmitter LED and the receiver ready LED glow red to indicate low battery (typically less than 60 minutes remaining).
    • NiMH rechargeable batteries may be used. However, the low battery indicator functions differently. When it turns red, there may be little to no remaining life.
    • When the LED flashes red, the batteries must be replaced to power on the transmitter.

    Wearing the Bodypack Transmitter

    Clip the transmitter to a belt or slide a guitar strap through the transmitter clip as shown.

    For best results, the belt should be pressed against the base of the clip.

    Adjusting Levels

    Adjusting Gain

    For best audio quality, set transmitter gain so the audio LED on the receiver flickers green and amber during the performance. Decrease gain if the signal clips (LED turns red).

    The amber LED may appear to be red when viewed at an angle. For best results, monitor the LED from directly in front.

    Bodypack Transmitter

    The bodypack has 26 dB of audio gain adjustment.

    • Increase gain (clockwise +) for microphones
    • Decrease gain (counterclockwise –) for guitars or high-output instruments

    Handheld Transmitter

    Access the gain switch by unscrewing the head of the microphone.

    Use the tip of a pen or a small screwdriver to move the switch.

    • 0dB: For quiet to normal vocal performance.
    • -10dB: Use only if audio is distorted due to high vocal levels.

    Single System Setup

    1. Scan: Use the scan feature on the receiver to find a clear channel.
      1. LED screen displays current channel
      2. Press channel button to scan for a clear channel
      3. System scans for the channel with the least interference
    2. Synchronize: Synchronize the transmitter to the receiver by aligning the infrared (IR) ports and pressing the sync button. Make sure the IR ports are closely aligned. After a successful sync, the transmitter LED momentarily flashes red and the receiver ready light illuminates.

    This wireless system may be affected by RF interference when used in proximity to other wireless devices such as cordless phones, baby monitors, and two-way radios. For best results, use the scan and sync feature before each use or if you experience problems.

    Multiple System Setup

    Use the following steps to ensure the best performance when installing multiple wireless systems at the same location.

    1. Turn all receivers on and all transmitters off.
    2. Turn on any other digital equipment that could cause interference during the performance so it will be detected during the frequency scans in the following steps.

    3. Make sure the group number is the same for all receivers (see Manual Group Selection).
    4. Perform a scan using the first receiver.
    5. Turn on the first transmitter and sync it to the receiver.
    6. Repeat for each system.

      After syncing each transmitter, leave it on so that scans from the other receivers will not select that channel.

    • Be sure only one transmitter IR port is exposed when synchronizing each system.

    Compatible Frequencies

    When operating multiple systems simultaneously, choose one group from the following table and set all systems to different channels within that group.

    Number of Systems Group (by band)
    X8 X8A (Australia) X8B (Brazil)
    2 0 to 9 0 to 9 0 to 9
    3 3 to 9 3 to 9 3 to 9
    4 3 to 9 -- 3 to 9
    5 7 to 9 -- --

    Manual Channel and Group Selection (receiver only)

    Using the receiver to scan for a channel is the best way to find the best frequency for your system. However, for multiple system setup, you may need to manually set the group number.

    1. Press and hold the channel button.
    2. Hold the button until the channel or group display begins flashing.
    3. Release and press the button again to advance the setting. At the desired channel or group number, wait for the flashing to stop. This activates the new setting.
    4. Transfer the new frequency setting to the transmitter using the automatic sync function.

    Locking and Unlocking Controls

    Locking the system controls prevents accidental muting or channel adjustment during performances.
