WARNING!USING THIS SYSTEM AT EXCESSIVE VOLUMES CAN CAUSE PERMANENT HEARING DAMAGE.USE AS LOW A VOLUME AS POSSIBLE.In order to use this system safely, avoid prolonged listening at excessive sound pressure levels. Please use the followingguidelines established by the Occupational Safety Health Administration (OSHA) on maximum time exposure to soundpressure levels before hearing damage occurs. 90 dB SPL at 8 hours95 dB SPL at 4 hours100 dB SPL at 2 hours105 dB SPL at 1 hour110 dB SPL at 1/2 hour115 dB SPL at 15 minutes120 dB SPL — avoid or damage may occurIt is difficult to measure the exact Sound Pressure Levels (SPL) present at the eardrum in live applications. In additionto the volume setting on the PSM, the SPL in the ear is affected by ambient sound from floor wedges or other devices.The isolation provided by the fit of quality earpieces is also an important factor in determining the SPL in the ear.Here are some general tips to follow in the use of this product to protect your ears from damage:1. Turn up the volume control only far enough to hear properly.2. Ringing in the ears may indicate that the gain levels are too high. Try lowering the gain levels.3. Have your ears checked by an audiologist on a regular basis. If you experience wax buildup in your ears, stop usingthe system until an audiologist has examined your ears.4. Wipe the ear molds with an antiseptic before and after use to avoid infections. Stop using the earphones if they arecausing great discomfort or infection.This symbol indicates that dangerous voltage constituting a risk of electric shock is present within this unit.This symbol indicates that there are important operating and maintenance instructions in the literature accompanyingthis unit.FCC Statement. The P4R Receiver complies with part 15 of the FCC rules. Operation issubject to the following two conditions: (1) this device does not cause harmful interference,and (2) this device must accept any interference received, including interference that maycause undesired operation.Licensing Statement. A user license may be required for operation. Contact the com-munications authority in your country for more information.Modifications to Approved Equipment. Changes or modifications not expressly ap-proved by Shure Brothers Incorporated could affect compliance with telecommunicationsstandards, thereby voiding the user’s authority to operate this product.
IntroductionThank you for buying the P4T Transmitter. The P4T is a component in the PSM400 family of wireless personal monitors. When used in conjunction with a P4RReceiver, it provides the many advantages of an in–ear monitoring system, including:SImproved Sound Quality - high fidelity without the risk of feedback,SIncreased Mobility - your mix moves with you,SPersonal Control - through volume adjustment and MixMode.This user’s guide covers the use and features of the P4T Transmitter. For further instruction on the use of the PSM400 system, see the PSM400 system user’sguide, availaible on the web at www.shure.com.P4T Transmitter Features123456789Front PanelBack Panel1. Local Earphone Output Jack (1/8 inch): Connects to E1 or E5earphones.2. Local Earphone Level Control: This knob adjusts the volume ofthe local earphone jack’s amplifier. Always listen at low levels.3. Input Level LEDs: Two vertical strings of four LEDs display theinput level of the left and right input channels. The four LEDs onthe left displays the status of the signal from channel 1 and thefour LEDs on the right displays the status of the signal fromchannel 2:LED Signal StatusRED (top) Limiter ActiveYELLOW (middle) Nominal LevelGREEN (bottom two) Signal Present4. Frequency Select LED: This indicates which of the 16 Chan-nels (0 - 9 and A - F) is selected.5. Frequency Select Button: This recessed button allows thetransmission channel to be changed. To use, hold down thebutton until the desired channel number is displayed in theLED. Release the button and the number will flash. Quicklypush and release the button again to confirm changes.6. Front-Mounted Antenna: The units antenna is permanentlyattached and break-resistant.7. Loop Out Jacks: Two 1/4” TRS jacks allow the audio signal topass through the transmitter to other devices, such as othertransmitters, tape recorders, or amplifiers.8. Input Jacks: Two 1/4” TRS Switching Jacks for line level audioinputs. If only one input is used, the signal will be routed to bothsides of the modulator for Mono operation. If both Jacks areused, the signals will be transmitted in Stereo/MixMode.9. 12VDC Locking Connector: Input for PS40 Power Cord.Set Up and OperationFollow these directions to set up the P4T for operation.1. Plug the power cord into the P4T’s 12 VDC locking power connec-tor. Plug the other end of the power cord into a wall outlet.2. Connect line level outputs of an audio source into the audioinputs of the P4T transmitter. Use both of the P4T’s input jacksfor a two-channel source. Use either input jack for a monosource. The P4T Transmitter will transmit in MixMode/Stereo ifboth inputs are used, but will automatically transmit in mono ifonly one input is used.NOTE: All inputs are phantom power protected up to 50 VDC.3. Select an operating frequency using the Frequency Select Button.The selected frequency will be displayed in the LED.IMPORTANT: Never set more than ONE transmitter to thesame operating frequency.4. Once audio is being transmitted by the P4T, observe the InputLevel LEDs. If the input signal is consistently causing the redLED to illuminate, decrease the output level of the audio sourceuntil the red LED only flickers occasionally.5. Set up the P4R receiver as directed in the P4R user’s guide,making sure that the frequency selected on the receivermatches the frequency selected on the transmitter.
LOOP ApplicationsThe LOOP OUT L (left) and R (right) outputs allow the signal going through the P4T to be routed to other devices. The LOOP feature of the P4T can be usedfor any number of applications. Shown here are only a few examples of how it can be used. MIXERFloor MonitorAmplifierP4T TransmitterP4R ReceiverRunning Floor Monitors Through a P4T TransmitterAn audio signal can be sent through the LOOP connectors to an amplifier for an onstage monitor system. When setup this way, the P4R and the onstage monitorswill reproduce the same audio.MONITORMIXMONITORMIXMIX OUT 1MIX OUT 2MONITORMIXMIX OUT 2SOLO MIXSOLO MIXSOLO MIXBAND MIXBAND MIXBAND MIXRunning Multiple PSM Wireless Systems Under MixMode ControlA single mono monitor mix can be sent to multiple P4T transmitters, then independent monitor mixes or direct outputs can be sent to the second channel of each.This will allow an entire band to hear the same monitor mix, while giving each individual player a separate mix of their own. Each player can then use the balancecontrol to adjust the levels between their own mix and the main mono monitor mix.MONITORMIX MIX OUT 1 MIX OUT 2MONITORMIXNOTE: See the P4M and PSM400 User’s Guides for forther information on this feature.MONITORMIXMONITORMIXAUDIO INAUDIO OUT TOFRONT-OF-HOUSEMONITORMIXMIX OUT 1MIX OUT 2Running Two PSM Wireless Systems Under MixMode Control From a P4M MixerWhen using the P4T in conjunction with a Shure P4M Mixer, a single mono monitor mix can be sent unaltered to two P4Ts. Each P4T can also receive a seperateMix Out signal, providing each P4T with a common monitor mix and a custom mix created by the P4M. The balance control on the P4R receiver is used to adjustthe levels betwen the monitor mix and the P4M mix.Running a Recording Device Through a P4T TransmitterIf you would like to make a recording of a performance, the LOOP outputs can be connected to the inputs of a tape deck, DAT, or other recording device.
