The equipment may be used in dry rooms only. 3. The equipment may be opened, serviced, and repaired by authorized personnel only. The equipment contains no userserviceable parts. 4.
2 Description 2.1 Introduction Thank you for purchasing an AKG product. This Manual contains important instructions for setting up and operating your equipment. Please take a few minutes to read the instructions below carefully before operating the equipment. Please keep the Manual for future reference. Have fun and impress your audience! 2.2 Packing List 1 SR 4500 receiver 2 UHF antennas 1 19” rack mounting kit • Check that the packaging contains all of the components listed above.
2 Description - Turn all the way CW to select a menu item or increase a parameter value. - Turn all the way CCW to select a menu item or decrease a parameter value. 4 Sticker: Indicates the receiver frequency version. 5 LED ring (green/red): If one or more warning functions are activated (see section 4.3), the LED ring will be lit red when a critical condition occurs. As long as all parameters are within their normal ranges, the LED ring is lit green.
3 Setting Up ! L Important! • Prior to setting up the receiver, check that the AC mains voltage stated on your power supply is identical to the AC mains voltage available where you will use your system. Using the power supply with a different AC voltage may cause damage to the unit. Note: • In the the following sections, flashing characters are identified by angle symbols ">" and "<". All numerical values shown are examples of possible settings. 3.
3 Setting Up In LOCK mode, the receiver receives the transmitter signal. The receiver is electronically locked so you cannot make any adjustments. You may, however, call up the various status screens one after the other. The "LOCK" label is shown on the display. To scroll through the following status screens, turn the SETUP control CW or CCW: 3.
3 Setting Up 3.8.2 Automatic Frequency Selection for Multichannel Systems 1. Select the frequency on the first receiver (refer to section 3.8.1 above). 2. Switch ON any radio microphones, personal monitor transmitters, etc. (including even those made by other manufacturers)! This is the only way to make sure the receiver will find frequencies that will be free of any mutual interference during the performance. 3.
3 Setting Up The Environment Scan function automatically searches the receiver's entire frequency band from Start to Stop (see Manual Supplement) for interference frequencies. During the search, the audio output is muted and the display indicates the frequencies in MHz as they are scanned. The frequency spacing for the automatic scan is 100 kHz.
3 Setting Up 4. The RF meter on the receiver extinguishing and the "MUTE" message appearing mean that no signal is being received or the squelch is active. Switch the transmitter ON, move closer to the receiver, or set the squelch threshold to the point that the "MUTE" message will disappear and the RF meter come on again. 3.9.
3 Setting Up 1. Be sure to assign a separate carrier frequency to each wireless channel (transmitter and receiver). 2. To find intermodulation-free carrier frequencies quickly and easily, we recommend using Automatic Frequency Selection (see sections 3.8.1 and 3.8.2) to select all required frequencies from the same Frequency Group within the same Preset. 3. Do not operate two or more wireless channels on the same frequency at the same location and time.
4 Extra Functions 4.1 Introduction 1. Select “X-TRA / EXTRA”. 2. Press the SETUP contgrol briefly. The “X-TRA / EXTRA” menu provides the following submenus: - “>NAME<” - “>STATUS<” - “>THRESH<” - “>INFO<” - “>EXIT<” - “>LIGHT<” - “>RESET<” 3. To call up the submenus in the above order, turn the SETUP control CW. The last submenu is followed by the first. 4. To call up the submenus in reverse order, turn the SETUP control CCW. The first submenu is followed by the last. 5.
4 Extra Functions 4.5 INFO The ">INFO<" submenu lets you call up information about your receiver. 1. Select “X-TRA / EXTRA” -> “>INFO<”. 2. Press and turn SETUP to call up the following screens: - Software version - Frequency band - Preset version - “EXIT”: To leave the ">INFO<" submenu, press the SETUP control briefly. The display will revert to the “X-TRA / EXTRA” menu. The “>LIGHT<” submenu allows you to adjust the brightness of the display backlighting in 10 increments from dark to bright.
6 Troubleshooting Problem No sound. Possible Cause 1. AC adapter is not connected to receiver and/or power outlet. 2. Receiver is OFF. 3. Receiver is not connected to mixer or amplifier. 4. Microphone or instrument is not connected to bodypack transmitter. 5. Transmitter is tuned to different frequency than receiver. 6. Transmitter is "OFF" or transmitter MUTE switch at "MUTE". 7. Transmitter batteries are not inserted properly. 8. Transmitter batteries/battery pack dead. 9.
