Power-save mode: When there are no earphones plugged in for 5 minutes, the receiver enters power-save mode to preserve battery life. The LED slowly fades on/off in this mode and continues to display the color that represents the remaining battery life.

Note: Battery life using Energizer brand AA Alkaline batteries and the following conditions:

  • Receiver audio set to V LIMIT = 0dB
  • Transmitter audio INPUT set to Line+4 dBu and Level set to −9 dB
  • Audio input to the transmitter: pink noise at +8.7 dBV
  • Audio output at receiver: 115 dB SPL in ear with SE425 earphones (impedance at 22 Ώ) set at volume level 4.

Note: Using lower-impedance earphones or ones with different sensitivity, different battery types, and higher gain settings in the PSM system may cause the receiver battery life to be different than specified.

Pink noise is a signal with a frequency spectrum such that the power spectral density is inversely proportional to the frequency. In pink noise, each octave carries an equal amount of noise power.

Multiple System Setup

When setting up multiple systems, designate a single bodypack to scan for available frequencies and download them to all the rack units.

The bodypack must be from the same frequency band as all the transmitters.

  1. Power on all the rack units. Turn off the RF. (This prevents them from interfering with the frequency scan.)

    Note: Turn on all other wireless or digital devices as they would be during the performance or presentation (so the scan will detect and avoid any interferance they generate).

  2. Use the bodypack to scan for a group by pressing and holding the scan button for two seconds. The bodypack displays the group and the number of available channels, and flashes SYNC NOW....

    Important: Note the number of available channels. If you have more rack units than available channels, eliminate potential sources of interference and try again, or call Shure Applications for assistance.

  3. Sync the bodypack with the first rack unit by aligning the IR windows and pressing sync.
  4. Press scan again on the bodypack to find the next available frequency.
  5. Sync the bodypack with the next rack unit.
  6. Repeat with all the rack units.
  7. Sync each performer's bodypack to its respective rack unit by aligning the IR windows and pressing snyc. DO NOT press scan on the bodypacks.
  8. Turn on the RF on all rack units. The systems are ready to use.

CueMode

CueMode allows you to upload the name and frequency settings from multiple rack units and store them as a list on a single bodypack. You can then, at any time, scroll through that list to hear the audio mix from each transmitter, just as each performer does during a show.

CueMode lists are retained even if CueMode is exited, the bodypack is turned off, or batteries are removed.

Note: Set the channel frequency and assign display names for each transmitter before creating your CueMode list.

Adding Transmitters to the CueMode List

Note: The transmitter must be from the same frequency band as the bodypack.

  1. Open the battery door and press the enter button.
  2. From the main menu, scroll to UTILITIES and press enter. Select CueMode and press enter again.
  3. Align IR windows and press sync on the rack unit.

    The LCD displays SYNC SUCCESS after frequency and name data are uploaded to the CueMode list. It also displays the CueMode number for that transmitter and the total number of transmitters.

  4. Repeat the above step for each transmitter.

Note: Syncing while in CueMode does not change any of the settings on the bodypack.

Auditioning Mixes

  1. Enter CueMode from the UTILITIES menu.
  2. Use the ▼▲ buttons to scroll through your CueMode list to hear the mixes.

Exiting CueMode

Exit CueMode by pressing enter and selecting EXIT CUEMODE.

Managing CueMode Mixes

While in Cue Mode, you can access the following menu by pressing enter:

REPLACE MIX

Select and press sync on a rack unit to upload new data for the current mix (for example, if you have changed the transmitter frequency).

DELETE MIX

Removes the selected mix.

DELETE ALL

Removes all mixes.

EXIT CUEMODE

Exits CueMode and returns the bodypack to the previous frequency setting.

Frequency Scan

Use a frequency scan to analyze the RF environment for interference and identify available frequencies.

  • Channel Scan Press the scan button on the bodypack. Finds the first available channel.
  • Group Scan Press and hold the scan button for two seconds. Finds the group with the greatest number of available channels. (Each group contains a set of frequencies that are compatible when operating multiple systems in the same environment.)

Note: When performing a frequency scan:

  • Turn off the RF on the transmitters for the systems you are setting up. (This prevents them from interfering with the frequency scan.)
  • Turn on potential sources of interference such as other wireless systems or devices, computers, CD players, large LED panels, effects processors, and digital rack equipment so they are operating as they would be during the presentation or performance (so the scan will detect and avoid any interference they generate).

Sync

You can transfer frequency settings in either direction: from the bodypack to the rack unit, or from the rack unit to the bodypack.

Note: You can also choose to transfer other settings to the bodypack during a sync, such as lock or mode settings, using the Sync > RxSetup menu on the rack transmitter.

Downloading settings from the bodypack

  1. Press the scanbutton on the bodypack.
  2. Align the IR windows and press the syncbutton from the rack transmitter LCD menu while the bodypack display is flashing "SYNC NOW...".

The level LEDs on the rack unit flash.

Sending settings to the bodypack

  1. Press the Sync button on the rack transmitter to access the sync menu.
  2. Align the IR windows.

    When properly aligned the IR window on the transmitter illuminates.

  3. Press Sync to transfer settings.

    The blue LED on the bodypack flashes.

MixMode

Some performers need to hear more of their own voice or instrument, while others want to hear more of the band. With MixMode, the performer creates their own mix using the balance control (▼▲ buttons) on the bodypack.

To use MixMode, send a solo mix of the performer to the L/CH1 input on the transmitter, and send a band mix to the R/CH2 input.

Set the performer's bodypack for MixMode. The bodypack combines the two signals and sends them to both earphones, while the balance control on the bodypack adjusts the relative levels for each.

For IFB applications, send two independent program feeds into the L/CH1 and R/CH2 input of the transmitter. With MixMode, the director or broadcast talent can listen to either feed using the balance control (▼▲ buttons) on the bodypack to pan to either audio signal.

LOOP Applications

Use LOOP OUT L (left) and R (right) outputs to send a copy of the audio signal going into the transmitter to other devices. Following are a few of the many applications for these outputs.

Note: The input level control and the input pad do not affect the LOOP OUT signals.

MixMode for Multiple Systems

Configure each system for MixMode. From the mixing console, send a mix of the whole band to input 2 of the first transmitter. Connect the LOOP OUT R output to the R/CH2 input of the next transmitter. Continue the chain with all the transmitters.

Next, create solo mixes for each performer. Send each mix to input 1 of the transmitter for that performer.

Floor Monitors

Send the audio from the LOOP outputs to onstage loudspeakers. The bodypack and the onstage monitors receive the same audio signals.

Note: The LOOP audio outputs will not drive passive loudpeakers, and must be sent to a power amplifier or an active loudspeaker.

Recording Devices

To record a performance, connect the LOOP outputs to the inputs of a recording device.

Squelch

Squelch mutes audio output from the bodypack when the RF signal become noisy. While squelch is activated, the blue LED on the bodypack turns off.

For most installations, squelch does not need adjustment, and it keeps the performer from hearing hiss or noise bursts if the RF signal becomes compromised. However, in congested RF environments or in close proximity to sources of RF interference (such as large LED video panels), the squelch may need to be lowered to prevent excessive audio dropouts. With lower squelch settings, the performer may hear more noise or hiss, but will experience fewer audio dropouts.

Important: Before lowering squelch, first try to eliminate the problem by finding the best set of frequencies for your installation and removing potential sources of interference.

Caution: Turning off or lowering the squelch setting can increase the noise level and cause discomfort to the performer:

  • Do not lower the squelch setting unless absolutely necessary.
  • Turn earphone volume to the lowest setting before adjusting squelch.
  • Do not change the squelch setting during a performance.
  • Turn up the transmitter level setting to make noise or hiss less noticeable.

Squelch Settings

HIGH (NORMAL) Default factory setting.
MID Moderately decreases the signal-to-noise ratio required to squelch the receiver.
LOW Greatly decreases the noise squelch threshold.
PILOT ONLY* Turns off noise squelch leaving only pilot squelch on.
NO SQUELCH* Turns off noise and pilot tone squelch. (Sometimes used as a debugging tool by monitor engineers or RF coordinators to "listen" to the RF environment.)
* Symbol appears in display window.

Point-to-Point Wireless Audio

Use PTP mode to allow a P9T to transmit to a UHF-R receiver. This allows a transmitter and receiver setup where both units are racked and powered by AC.
