Getting Connected Connecting Power 1. Ensure the main power switch on the rear panel is set to OFF. 2. Connect the power adapter to the power input on the rear panel. 3. Plug the power adapter into a power outlet, or a surge protector. Note: A surge protector is recommended to protect your equipment from power surges. Connecting Audio Using the XLR outputs The XLR outputs allow you to connect each channel to the mixer independently.
Getting Connected Connecting Antennas The Antennas receive the UHF wireless signals from the microphones. 1. Attach the antennas to the connectors on the front panel by twisting them clockwise until firmly attached. 2. To disconnect the antennas, twist counter-clockwise. Note: Please be sure to attach the 900MHz antennas to the top 2 antenna posts and attach the 600MHz antennas to the bottom 2 posts.

Descriptions and Functions 1 2 3 4 5 6 7 Module Display Window 1. MUTE Indicator - Displays when corresponding mic is off or disconnected. The Mute Mode is an automatic function. 2. Group and Channel - Displays the group and channel that the module is set to. *See Displaying the Group & Frequency page for details. 3. IR (infrared) Mode Indicator - Indicates when the module is in IR Mode, which is used to assign a microphone to a module. 4.
Descriptions and Functions Microphones 1. IR (infrared) Sensor - This sensor receives the infrared signal that is used to set the frequency that the wireless mic will use. This sensor is only used to set the microphone frequency, it does not send or receive audio signal. 2. Power LED - This LED indicator will turn green when the microphone is turned on. It will turn red when the batteries need to be replaced. 3. ON/OFF Switch - This switch turns the microphone on or off.
Setting up the Microphones Overview The goal is for each of the UHF-8900’s wireless channels to be operating on a frequency free of interference. This can be accomplished two ways 1) automatic frequency selection, and 2) manual frequency selection. We recommend using the automatic method first, as this method will work well for most areas. However, if you live in a metropolitan area where RF activity is dense, manual frequency selection may work better for you.
Setting up the Microphones Setting the Frequencies Automatically The microphones will be ready to use right out of the box. The below instructions are intended if interference is experienced at the venue being performed at. The Automatic instructions should be tried first and if problems persist, try the Manual settings. Note: Please read through the steps before attempting to sync the microphones.
Setting up the Microphones Setting the Frequencies Manually If the UHF-8900 is used in an area with heavy RF interference, it may be beneficial to set the frequencies manually. Please refer to the Advance Operation page to determine which frequencies to use for that area. Note: Please read through the steps before attempting to sync the microphones. The module menus have a 4 second timeout period where if a button is not pressed within that time the module will revert back to the frequency information page.
Re-syncing the Wireless Mics Occasionally the microphone will need to be re-synced with the respective module. The frequency is the same but the connection between mic and module is lost. Note: Please read through the steps before attempting to sync the microphones. The module menus have a 4 second timeout period where if a button is not pressed within that time the module will revert back to the frequency information page. 1.
Using the Wireless Mics Microphone Position The UHF-8900 is ideal for close-up vocals and can be held in the hand or mounted on a mic stand. Keep in mind that microphone technique is largely a matter of personal taste, and there is no one “correct” microphone position. Feedback Feedback occurs when the amplified sound from any loudspeaker reenters the sound system through any open microphone and is repeatedly amplified.
Basic Operations Setting Up with Stage Monitors/P.A. System If you will be using the UHF-8900 with stage monitors and/or a P.A. system, try the following: • Place the stage monitor directly in front of the microphone. • Locate the P.A. loudspeakers so that they point away from the rear of the microphone. (With the speakers located in these positions, the possibility of feedback is greatly reduced). • Always check the stage setup before a performance to ensure optimum placement of microphone and monitors.
Advanced Operation Testing a Channel for Outside Interference Once a microphone and module have been successfully paired, turn the microphone OFF (leave the module ON). With the microphone off, if the RF indicator still has bars showing, there exists interference. Note that RF interference can ebb and flow. Sometimes it may appear as 4 steady bars on the RF indicator, other times, it may weakly occupy a single bar or two. Generally, we recommend looking for another channel if ANY bars register.
Displaying the Group & Frequency The module LCD displays all the information regarding the microphone Group (GR) and Channel (CH). It is important to understand what each icon represents. • Frequency: This is the frequency that the microphone is currently using. It is easier to refer to this as a combination of both Group and Channel numbers. For example: 655.MHz would be GR 2-1 & CH 01. • Group: The Group number is the subset of frequencies to choose from in each module.

Troubleshooting There is no power • Make sure the power adapter cord is firmly connected to the back of the UHF-8900 and to the power outlet. • If using a power strip/surge-protector, make sure that it is plugged in and switched on. • Make sure the rear panel power switch and the front panel module power switches are turned on. There is no sound • • • • • • Make Make Make Make Make Make sure sure sure sure sure sure everything is connected firmly and properly. there are no defective cables.
