Single System Setup

Follow these steps when using a single SLX system:

Automatic Frequency Selection

Scans for an available channel and sets the receiver to that channel.

Automatic Transmitter Setup

  1. Turn On the transmitter.
  2. Open the transmitter battery compartment to display the infrared (IR) port
  3. With the IR port exposed to the receiver, press sync.
  4. Hold the sync button until the red light stops flashing on both receiver and transmitter.
  5. When the receiver ready light glows, the system is ready for use.
  6. Close the transmitter battery compartment.

Multiple System Setup

Follow these steps when using multiple SLX systems in a single installation:

  1. Turn all receivers on and all transmitters off.
  2. Set all receivers to the same frequency group.
  3. Perform Automatic Frequency Selection from the Single System Setup section above.
  4. Turn on the first transmitter.
  5. Perform Automatic Transmitter Setup from the Single System Setup section above.
  6. Repeat for each system.

    Be sure that only one transmitter’s IR port is exposed when synchronizing a system.

On/Off switch

Tap to turn on, hold to turn off.

Receiver Volume Control

The volume control dial should generally be left in the clockwise position. Turning the dial counter-clockwise decreases receiver output level.

If adjustments are necessary, use a small screwdriver to turn the dial.


Full Group Warning

The FULL warning indicates that all available channels in the currently selected group are in use. When this occurs, reprogram all systems to an alternate group.

Press either the menu or select button to exit the warning screen.

Transmitter Battery Status

Indicates a low transmitter battery charge.

Antenna Status

Indicates RF activity. Only one antenna is active at any one time.

SLX4 Receiver Programming

Any option displayed on screen will generally “time out” after five seconds.

Group Selection

Allows manual selection of a frequency group. Pressing select increases the group number by one. When the correct frequency is displayed, either wait five seconds for the screen to time out, or press sync. For best results when operating multiple systems, set all systems to a single group; then set each system to a unique channel within that group.

Wearing the Bodypack Transmitter

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

For best results, slide the transmitter until the belt is pressed against the base of the clip.

If the receiver LED indicates the input volume is overloading the receiver, try switching the gain to a lower setting.


Adjusting Gain

Three gain settings are available on the SLX1. Choose the appropriate setting for your instrument.

  • mic: Microphone (higher amplification)
  • 0: Guitar with passive pickups (medium amplification)
  • –10: Guitar with active pickups (lower amplification)


Adjusting Gain

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

Two gain settings are available on the SLX2. Choose a setting appropriate for vocal volume and for the performing environment. Use the tip of a pen or a small screwdriver to move the switch.

  • 0dB: For quiet to normal vocal performance.
  • –10dB: For loud vocal performance. If the receiver LED indicates the input volume is

SLX1 and SLX2 Transmitter Programming

Manually Select a Group and/or Channel

  1. Press and hold the select button until the GROUP and CHANNEL displays alternate.
  2. To change the group setting, release the select button while GROUP is displayed. While GROUP is flashing, pressing select increases the group setting.
  3. To change the channel setting, release the select button while CHANNEL is displayed. While CHANNEL is flashing, pressing select increases the channel setting.

Lock or Unlock Transmitter Settings

Press the mute and select buttons simultaneously to lock or unlock the transmitter settings. When locked, the current settings cannot be changed manually. Locking the transmitter does not disable infrared synchronization.

Frequency Band Selection

Most countries closely regulate the radio frequencies used in the transmission of wireless information. These regulations state which devices can use which frequencies, and help to limit the amount of RF (radio frequency) interference in all wireless communications.

To be flexible enough to operate worldwide, SLX receivers are available in a number of models, each with a unique frequency range. Each frequency range, or band, spans up to 24 MHz of the wireless broadcast spectrum.

To facilitate system setup and protect against RF interference, each system comes with multiple predefined frequency groups and channels.

When using a single SLX system, the operating frequency will generally not have to be changed. In an installation with multiple receiver/transmitter systems, each system must operate on a separate channel. The group and channel system provides an optimum frequency spread when using multiple systems.

Within a single frequency band, up to 12 individual transmitter/receiver systems may be used in a single installation. In regions where additional frequency bands are available, it is possible to operate up to 20 systems simultaneously. Check with your local Shure retailer for information on which bands are available in your area.

The Master Frequency List

Using the Master List

The “Master List” of frequencies should be accessed only by experienced users in situations which call for precise frequency selection. The “Master List” is a comprehensive index of all available frequencies in 25 kHz increments. (125 kHz increments in the JB band.)

To access the Master List, hold down the menu button while powering on the SLX receiver.

Select Frequencies in the Master List

While FREQUENCY SELECT is flashing, the select button scrolls down through all available frequencies; the menu button scrolls up. Press and release to change the frequency in 25 kHz increments; press and hold to scroll quickly.

When the correct frequency is displayed, either wait five seconds for the screen to time out, or press sync.

Exit the Master List

To exit the Master List and return to normal system operations, press menu, then select.
