Antennas

Active Antennas

The antenna connectors on the ULX receiver provide 12 V DC for active circuit antennas.

Caution: Use only Shure antenna accessories to ensure the best operation. Do not use splitters, combiners, or antennas that provide a DC ground, as this can cause the receiver to function improperly.

Antenna Combiners and Accessories

The supplied antennas can be connected directly to the BNC-type ANTENNA connectors. However, optional antenna mounting accessories from Shure can improve reception and reduce rack clutter. Use the following guidelines:

Antennas and receivers must be from the same band.
Mount antennas more than 40 cm (16 inches) apart.
Use Shure UA825 or UA850 low-loss coaxial antenna cable (or any 50 ohm, low-loss cable such as RG-8U).

Use the lock feature to avoid accidental muting of the microphone during a performance.

Power Indicator (BAT)

Green: ready

Red: battery power low

Note: Remaining battery life varies with battery type.

Battery Indicator

Both the transmitter and receiver LCD shows approximate operation time remaining for the transmitter.

Single System

If you encounter wireless interference, perform a channel scan on the receiver and use the selected channel. You usually do not need to change the group.

Multiple Systems

To maximize performance, set all wireless systems to different channels from the same group. These channels are selected to work well together.

Follow these steps when using group and channel scan with multiple systems.

Power off all system transmitters. Turn on all other wireless or digital devices as they would be during the performance or presentation.
On the first receiver: Perform a group scan. Note the selected group, then use channel scan to find the first open channel in that group.
Power on the first transmitter and set it to the selected group and channel.
IMPORTANT: Leave the first transmitter powered on while setting up the next system.
For each additional system: Set to the same group as the first. Perform a channel scan and set the receiver and transmitter to the selected channel.
Leave each transmitter on while setting up additional systems.

Note:

Keep each transmitter at least two meters (6 feet) apart.
If using systems from different bands, set up all systems from the same band together.

Tip: To reduce setup time, you can manually set up the group and channels before arriving at the venue. Visit www.shure.com for a list of groups and channels that are anticipated to be free of interference in a particular city or region.

Automatic Frequency Scan

Channel Scan

This feature scans for an open channel in the selected group.

Group Scan (ULXP4 only)

The "group scan" feature on the ULXP helps maximize the number of systems you can install at a single venue. It scans for wireless interference and finds the group with the most open channels.

Changing Group and Channel

If you encounter wireless interference, set the receiver and transmitter to a different channel or group.

Change Channel

Change Group

* Note: You can reverse the scroll direction by holding SET and pressing MODE.

Wireless Indicators

RF Indicator

Indicates wireless activity over the selected channel.

Note: When the antenna and battery indicators are illuminated, the RF indicator shows signal strength from the transmitter. Otherwise, it is showing interference from another source. Select a different channel.

Antenna Indicator

This indicator shows which antenna is receiving the strongest signal from the transmitter.

Frequency Display

TV

For models sold in the United States only. Displays the TV channel occupied by the selected frequency.

Frequency Master List Mode

Master List mode offers more precise frequency selection for larger, multiple-system installations.

Enter Master List mode on the receiver or transmitter by holding down the SET button for 10 seconds. Set GROUP and CHANNEL as you would in normal mode.

Note: The unit must remain in Master List mode to operate at the selected frequency.

Exit Master List mode by holding the SET button for 10 seconds.

Squelch (ULXP4 Only)

The factory setting offers the optimum performance for most installations.

Increasing squelch filters out all but the highest quality signal, but this decreases operating range. Decreasing squelch extends the operating range, but can increase signal noise.

Audio Output

Audio Output Connectors

Balanced XLR: Connect to a mixer or other professional audio input. Use the MIC/LINE switch to adjust for microphone or line-level inputs.

Unbalanced 6.35 mm (1/4"): Connect to high impedance inputs, such as a guitar amplifier.

Note: The LINE/MIC switch does not affect the 6.35 mm (1/4") jack.

Receiver Output Level

Adjusts the level of the receiver's audio outputs.

PEAK Icon

This icon appears when the input signal overloads the transmitter. The icon is displayed for 2 seconds after input overload is detected.

Transmitter Gain

For best audio quality, adjust transmitter gain so only the green and yellow TX AUDIO LEDs flicker. (Occasional illumination of the red LED is okay.)

Green = nominal

Yellow = peak

Red = overload

ULX1

Set the attenuator (pad) switch to 0 dB for microphones and –20 dB for guitars. (Some low output instruments may not need attenuation.)
Adjust gain control as necessary.

ULX2

Fully clockwise for quiet to normal vocal performance.
Halfway counterclockwise for loud vocal performance.
Fully counterclockwise for horn or percussive instruments.

Locking the Receiver (ULXP4 Only)

This feature prevents accidental setting changes.

Unlocking

Hold the SET button while turning the control wheel left, right, left.

Note: If LEVEL flashes on the LCD, decrease the LEVEL control to continue. This feature safeguards against sudden level increases when the lock is removed.

Locking the Transmitter

Lock/Unlock Power (On)

Hold SET and MODE for four seconds or until the lock icon appears.

Lock/Unlock Frequency

Hold the SET button while powering on the transmitter.

Troubleshooting

No power: Check battery and power supply connections and voltage. Check the power switch on the transmitter.

The LCD displays "E0 00" or similar code: Exit master list mode by holding the SET button for ten seconds.

Can't turn off or change settings on the transmitter or receiver: The interface is locked. See the section on locking the interface.

No audio: If the antenna and battery indicators do not appear on the receiver, then it is not receiving a signal from the transmitter. Make sure the transmitter and receiver are tuned to the same group and channel.

Faint or distorted audio: Adjust transmitter gain, bodypack attenuator switch, and receiver output level.

Noise: Noise usually results from wireless interference or a weak signal from the transmitter. See Tips for Improving System Performance.

Tips for Improving System Performance

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

Replace the transmitter battery with a fresh alkaline battery (avoid rechargeable 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 (or remote mount antennas outside the rack).
Remove nearby sources of wireless interference, such as cell phones, two-way radios, computers, media players, and digital signal processors.
Keep transmitters more then two meters (6 feet) apart.
Keep the transmitter and receiver more than 5 meters (15 ft) apart.
Point the receiver antenna tips away from each other at a 45° angle, and keep them away from large metal objects.
During sound check, mark "trouble spots" and ask presenters or performers to avoid those areas.
