I PART I: GENERAL FCC Statement This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Parts 74, 15, and 90 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications.
PART I: GENERAL The PR 81 portable receiver is available separately or as a complete system with an HT 81 handheld transmitter or PT 81 bodypack transmitter. 1 PR 81 receiver 1 screwdriver 1 mini XLR to XLR connecting cable 2 AA size 1.5 V batteries 1 belt clip I 2.2 Unpacking 2.2.1 PR 81 Receiver Velcro tape for camera mounting 1 PR 81 receiver with accessories 1 SA 43 stand adapter 1 HT 81 handheld transmitter 1 screwdriver 2 AA size 1.
I PART I: GENERAL 2.3.3 PT 81 2.4 Frequencies CB 40 bag Color Coding Kit The PR 81 portable receiver, HT 81 handheld transmitter, and PT 81 bodypack transmitter have been factory programmed for up to 15 selectable carrier frequencies. A carrier frequency label on the receiver, on the handheld transmitter, or on the bodypack transmitter indicates the Frequency Set the unit uses and all available carrier frequencies.
PART II: PR 81 RECEIVER II 1g Antennas: Being a diversity receiver, the PR 81 uses two antennas in order to receive the transmitter signal at two different points in space. The diversity circuit will automatically activate the antenna that provides the better signal. 1h Color code platelet: If you use the receiver within a multichannel system, you can remove the black plastic platelet and replace it with a different color platelet from the optional Color Coding Kit.
II PART II: PR 81 RECEIVER Important: If you wish to set up a multichannel system, read section 1.1 Multichannel Systems in Part V first. 2.2 Powering To power the PR 81 portable receiver you can use the supplied 1.5 V AA size dry batteries, 1.5 V AA size rechargeable batteries (not supplied), or the optional PA 81 supply adapter for direct powering from a camcorder. 2.2.1 Inserting Dry or Rechargeable Batteries 1.
PART II: PR 81 RECEIVER II 18 V DC and has a fixed 20-in. (50-cm) connecting cable with stripped and tinned leads. An automatic fuse switches the PA 81 OFF if the supply voltage is shorted. The PA 81 requires a maximum power of 1 watt. 1. Check that the voltage source on your camcorder provides a voltage between 5 V DC and 18 V DC and sufficient current to satisfy the 1-watt power requirement of the PA 81. Also check what type of connector you will need. 2.
II PART II: PR 81 RECEIVER 2.6 Connecting Headphones To connect a pair of headphones to the receiver, you will need an optional MK HP adapter cable from AKG. This cable provides a mini XLR connector and a TS mini jack for connecting headphones with a mini jack plug. Important: In order to avoid overloading the headphone amplifier, do not connect headphones with an impedance of less than 16 Ω to the headphone output. 1.
PART III: HT 81 HANDHELD TRANSMITTER III 1 Description The HT 81 handheld transmitter and matching microphone elements (optional) provide the same acoustic performance as the equivalent hardwire microphone versions. The microphone elements available for the HT 81 have been specifically designed for vocal use. The HT 81 operates in a subband up to 3 MHz wide within the 710 MHz to 860.9 MHz UHF carrier frequency range.
III PART III: HT 81 HANDHELD TRANSMITTER 2 Setting Up 2.1 Selecting the Carrier Frequency 1. Unscrew the battery compartment cover CCW and remove the color code ring (2d or 2j) from the transmitter. All controls are now accessible. 2. Use the supplied screwdriver (1m) to set the CHANNEL control (2g) to the desired channel. 3. Set the CHANNEL control (1k) on the receiver to the same channel as the transmitter.
PART IV: PT 81 BODYPACK TRANSMITTER IV 1 Description You can use the PT 81 bodypack transmitter with both dynamic microphones and condenser microphones operating on a supply voltage of approx. 7 V. The PT 81 operates in a subband up to 3 MHz wide of the 710 MHz to 869 MHz UHF carrier frequency range. The PT 81 can be switched to a maximum of 15 different carrier frequencies depending on local frequency allocations. 3a POWER: Switches the transmitter power ON ("I") and OFF ("0").
IV PART IV: PT 81 BODYPACK TRANSMITTER Important: Be sure to switch power to the transmitter OFF every time before changing the carrier frequency. The new carrier frequency will not be activated before you switch the transmitter back ON. (If you change the carrier frequency while the transmitter is ON, the transmitter will remain tuned to the old carrier frequency.) Important: If you wish to set up a multichannel system, read section 1.2 Multichannel Systems in Part V first. 2.
PART V: OPERATING NOTES 2. The red AF LED (1hd on the receiver constantly lighting red and/or the status LED (2b, 3c) on the transmitter lighting constantly means the transmitter is overloaded. Turn the GAIN control (2e) or (3j) on the transmitter CCW to the point that the above LEDs will only flash occasionally. 3. Set the audio input level on your camcorder or on the mixer channel to which the receiver is connected. If the selected input provides phantom power, switch the phantom power OFF. 4.
VI PART VI: APPENDIX 1 Troubleshooting Problem No sound. Possible Cause 1. Receiver is OFF. Remedy 1. Set POWER switch on receiver to "I". 2. insert batteries into transmitter and/or receiver. 3. Connect receiver output to mixer or camcorder input. 4. Turn up audio level control on camcorder or channel fader on mixer. 5. Connect microphone to audio input on bodypack. 6. Set transmitter and receiver to the same frequency. 7. Set transmitter on/off switch to "ON". 8.
